Explanation:

Starch is a carbohydrate, but specifically a polysaccharide. Unlike fats they cant be broken down so #2 is not correct for that reason. Since polysaccharides are a polymer of complex sugars they can be broken down to simple sugars in order for it to enter cells because the cell needs to transport the molecules in small portions not big. That is when the different types of transport comes in. :)

One thing causing another is known as causation; in other words, action A results in outcome B. Nevertheless, correlation is just a relationship where action A is related to action B, even when one event does not always lead to the occurrence of the other.

However, a correlation between two variables does not necessarily imply that a change in one variable is the reason for a change in the values of the other. There is a causal relationship between the two occurrences, which means that causation shows that one event is the outcome of the occurrence of the other event.

In other words, just because two things correlate does not necessarily entail that one is the cause of the other. For instance, just because shoppers in the UK tend to spend more when it's cold outside and less when it's hot outside doesn't necessarily indicate chilly weather spurs on frenetic high-street shopping.

Answer:

“The Tibetan genome appears to arise from a mixture of two ancestral gene pools,” said Anna Di Rienzo, professor of human genetics at the University of Chicago and corresponding author of the study. “One migrated early to high altitude and adapted to this environment. The other, which migrated more recently from low altitudes, acquired the advantageous alleles from the resident high-altitude population by interbreeding and forming what we refer to today as Tibetans.”

High elevations are challenging for most humans because of low oxygen levels, but Tibetans spend their lives above 13,000 feet with little issue. They are better suited to that climate when compared to short-term visitors from low altitudes, thanks to physiological traits such as relatively low hemoglobin concentrations at altitude.

Unique to Tibetans are variants of the EGLN1 and EPAS1 genes, key genes in the oxygen homeostasis system at all altitudes. These variants were hypothesized to have evolved around 3,000 years ago, a date which conflicts with much older archaeological evidence of human settlement in Tibet.

Adaptations can be anatomical (how the organism is built), behavioral, or physiological (how parts of an organism function). About 800 people each year attempt to climb Mount Everest. Mount Everest is located on the border between Tibet and Nepal in the Himalayas in Asia. The dangers of climbing Mount Everest include avalanches, cracking ice flows, and deep deadly crevices. However, the most trouble that climbers run into is altitude sickness. Altitude sickness is a group of symptoms that can happen when walking or climbing in higher altitudes. Most cases of altitude sickness are mild, while some symptoms can be life threatening. When climbing Mount Everest, there is an area known as the “death zone” that climbers hit when they reach about 8000 meters above sea level. In the death zone, the lungs and brain do not get enough oxygen, the risk of stroke and heart attack increases, and judgment is impaired. Those native to the Tibetan plateau have adapted to living at high altitudes with lower oxygen levels and are able to help mountain climbers. Tibetans have several genes that allow them to use less oxygen when they are working or exerting energy. Scientist have studied the genes of the Tibetans and found when one version of a gene was expressed, or allele, the people had a 10 percent higher saturation of oxygen.

Reproduction is the biological process by which organisms produce new individuals. The male "train" ejects semen into a woman's "Destination", and lets the "passengers leave" (semen) and the semen must reach the female egg, from there it creates a fetus.

Coniferous forests experience cold, harsh winters and mild summers with low precipitation, while tropical rainforests have warm temperatures and high levels of rainfall year-round.

Plants in coniferous forests have evolved adaptations to survive in the cold temperatures and low precipitation. For example, coniferous trees have needle-like leaves that reduce water loss due to transpiration and a waxy coating on their leaves that protects them from cold temperatures. They also have shallow roots that can absorb nutrients from the top layer of soil, which is nutrient-poor due to the cold temperatures and slow decomposition rates.

In contrast, plants in tropical rainforests face different challenges. The high temperatures and rainfall in these ecosystems create a warm, humid environment that promotes rapid growth and high competition for resources. To survive in this environment, plants have developed adaptations such as large, broad leaves that maximize light absorption and transpiration, and aerial roots that absorb nutrients from the surrounding air and water.

In summary, the temperature and precipitation patterns in coniferous forests and tropical rainforests have shaped the adaptations of the plants that live there. Coniferous trees have evolved to withstand cold, dry winters, while tropical rainforest plants have adapted to the warm, humid conditions and intense competition for resources.

Trees and shrubs, giraffes (who eat trees and shrubs), and lions are all connected by a straightforward food chain (that eat the giraffes). Every link in this chain provides fuel for the one after it.

Energy from the sun is the source of all food chains. Plants capture this energy. There are at least two or three trophic levels in every food chain and web. There are often no more than four trophic levels. Many consumers consume food at various trophic levels. When people eat plants like vegetables, they are the main consumers.

Who eats whom is described in a food chain. All of the food chains in an ecosystem make into a food web. Each organism in an ecosystem resides at a certain trophic level, position, or web of relationships with other organisms. The base of the trophic pyramid represents producers—animals that synthesise their own food through photosynthesis or chemosynthesis.

Aquaculture is  technology have allowed for the raising and harvesting of fish for commercial sale.

The farmer's attempts to speed up and improve the growth of aquaculture species are what define aquaculture as a form of farming.

Aquaculture is the process of increasing populations of freshwater, brackish water, and saltwater species in artificial or semi-natural conditions, in contrast to commercial fishing, which also entails catching wild fish.

In contrast to fishing, these methods enable the selective expansion of production of the species that humans desire the most.

In coastal areas, the main potential threats to marine health are poisons, dregs, and overflow. The health of the marine ecosystem offshore is also assessed.

A natural researcher may be necessary, for example, to take into account the impact of an oil slick or other compound risk in the sea. In order to see concerns like the substance cosmetics of residue, the effect of disintegration, and the impact of digging sea bottoms on the marine condition, natural researchers also study the benthic conditions on the sea floor.

Option A is Correct. A synergist is a muscle that supports the muscle that performs the majority of an action.

Muscles that support or are in charge of supporting a similar group of joints during movement are known as synergist muscles. They play the agonist rather often. This muscle helps to create motion or movement close to a moveable joint.

For instance, the synergist muscle biceps brachii supports forearm flexion actions. At the muscle's origin, a fixator may also function as a synergist.

A tiny muscle called the teres major (TM) runs along the lateral aspect of the scapula. One of the seven scapulohumeral muscles, it aids in shoulder movement by acting on the glenohumeral joint.

The change in red blood cell volume is primarily due to the movement of water. The correct answer is 3.

Red blood cells, or erythrocytes, have the ability to regulate their volume through the process of osmosis. Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

In the case of red blood cells, they contain certain solutes, such as ions and proteins, that contribute to their internal solute concentration. When the surrounding environment has a higher solute concentration, water moves into the red blood cells to equalize the concentration. This causes the cells to swell and increase in volume.

Conversely, when the surrounding environment has a lower solute concentration, water moves out of the red blood cells, leading to their shrinkage and decrease in volume. This osmotic movement of water plays a crucial role in maintaining the proper volume and shape of red blood cells, which is essential for their optimal functioning in carrying oxygen and nutrients throughout the body.

While serum (option 1), oxygen (option 2), and salt (option 4) may influence red blood cell function and physiology in various ways, the primary factor responsible for the change in red blood cell volume is the movement of water through osmosis. Therefore, the correct answer is 3.

Answer:

DDT was first introduced in the United States in the 1940s as a powerful pesticide that was widely used to control insect populations.

DDT use led to the decline of the bald eagle population in the United States in the mid-twentieth century.

Bald eagles are at the top of the food chain and consume large quantities of fish, which can accumulate DDT in their bodies over time.

The accumulation of DDT in bald eagles led to a condition known as eggshell thinning, which caused the eggs to crack before they could hatch, resulting in a decline in the bald eagle population.

The thinning of eggshells occurs because DDT causes the female bald eagles to produce eggs with thinner shells.

As a result, many bald eagle chicks did not survive, leading to a decline in the population.

In addition to bald eagles, other bird species were also affected by the use of DDT, leading to a decline in their populations as well.

In the 1960s, research conducted by Rachel Carson and others brought attention to the harmful effects of DDT on the environment and wildlife.

As a result of this research, the use of DDT was banned in the United States in 1972.

Since the ban of DDT, the bald eagle population has shown signs of recovery, but is still considered a threatened species in many parts of the country.

Explanation:

"Catching the seeds" is possible in some crops due to their specific characteristics, such as self-pollination, and the ease with which their seeds can be collected and stored.

"Catching the seeds" refers to the practice of intentionally collecting and saving seeds from a crop in order to use them for planting in the next growing season. This is possible in some crops due to their specific characteristics and growth patterns.

One example of a crop in which "catching the seeds" is possible is beans. Beans are self-pollinating plants, which means that the flowers on each plant contain both male and female reproductive structures. This reduces the likelihood of cross-pollination and ensures that the seeds produced by each plant will be similar to the parent plant.

Another example of a crop in which "catching the seeds" is possible is tomatoes. Tomato plants produce fruit that contain seeds, and these seeds can be collected and saved for planting in the next season. Additionally, tomatoes are typically grown in a controlled environment, such as a greenhouse, which reduces the likelihood of cross-pollination with other tomato varieties.

The correct answer is: wildflowers, rabbits, foxes

Explanation:

The correct answer is: wildflowers, rabbits, foxes

In a food chain, energy is transferred from one organism to another in a linear sequence. The organisms at the beginning of the food chain are usually producers, such as plants, which are eaten by herbivores, such as rabbits. In turn, the herbivores are consumed by predators, such as foxes.

In a temperate deciduous forest, wildflowers are a common type of plant that can be eaten by rabbits, which are in turn eaten by foxes. Therefore, the correct food chain is wildflowers (producer) → rabbits (herbivore) → foxes (predator).

Phytoplankton are the foundation of the ocean food web, providing organic matter for virtually all other marine creatures. Their primary productivity limits the growth of crustaceans, fish, sharks, porpoises and other marine creatures. They are responsible for half of the photosynthetic activity on the planet. Phytoplankton’s role in the global ecosystem has made them a target for controlling carbon-dioxide levels in the earth’s atmosphere.

Giant kelp is a type of brown algae that grows in shallow, nutrient-rich saltwater near coastal fronts around the world. It provides habitat and food for a variety of marine organisms. Kelp and other types of marine vegetation absorb an estimated 20 times more carbon dioxide per acre than forests on land, making it a powerful force in storing this persistent greenhouse gas and mitigating the effects of climate change.

During the Calvin cycle, the process of carbon fixation occurs, in which carbon dioxide (CO2) is added to a five-carbon sugar molecule called ribulose-1,5-bisphosphate (RuBP) through the enzyme RuBisCO, forming an unstable six-carbon molecule.

This molecule immediately splits into two molecules of 3-phosphoglycerate (3-PGA), which can be further converted into glyceraldehyde-3-phosphate (G3P), a three-carbon sugar that can be used to build more complex organic molecules such as glucose.

The Calvin cycle is a series of biochemical reactions that occur in the chloroplasts of plants and algae and is essential for the process of photosynthesis, which converts light energy into chemical energy stored in the bonds of organic molecules.

Explanation:

After an extreme disturbance, the kind of organisms that move into an area first are the pioneer species.

After an extreme disturbance, such as a fire or volcanic eruption, pioneer species are often the first organisms to move into the area. These are typically hardy, fast-growing species that can quickly colonize the area and establish themselves in the newly available space.

In terrestrial ecosystems, pioneer species may include grasses, mosses, and lichens, which are able to quickly grow and spread across the disturbed area. These plants are often adapted to harsh environmental conditions, such as drought, high temperatures, and low soil nutrients, which may be present in the aftermath of a disturbance.

In aquatic ecosystems, pioneer species may include algae and other microorganisms, which can quickly colonize the available surface area and begin photosynthesizing. These organisms are often able to rapidly reproduce and establish themselves in the disturbed area, creating a foundation for other organisms to colonize the area.

Pioneer species play an important role in ecosystem recovery, as they help to stabilize the soil, build organic matter, and create habitats for other organisms. As the ecosystem recovers, other, more specialized species can move in and establish themselves, eventually leading to the development of a more complex and diverse ecosystem.
