Explain how the structure of a cell allows localization of reactions, protection from reactive molecules, and greater efficiency of cellular processes than a bacterial cell.
The structure of a eukaryotic cell allows localization of reactions because there are subcompartments in the cell where specific enzymes colocalize, protection from reactive molecules refers to structural barriers, while greater efficiency of cellular processes in this cell than a bacterial cell is based on the subdivision of work.
What does subdivision of work mean in terms of a eukaryotic cell?The expression subdivision of work mean in terms of a eukaryotic cell makes reference to the presence of different cell compartments such as those associated with particular organelles which provide a suitable medium to carry out particular reactions such as the presence of hydrolytic enzymes in lysosomes.
Therefore, with this data, we can see that the subdivision of work is fundamental in a eukaryotic cell in order to perform different tasks, which is translated to higher metabolic efficiency when compared to bacteria.

If a solution is 8% solute, it is [x]% solvent
If a solution is 8% solute, that means 8% of it (or 8/100ths) is made up of the stuff you added to it. We know that the whole solution is 100%. Therefore, we need to subtract 8% from 100%, which gives us 92%. We know this is correct since you can't have a less than 100% solution, since it exists wholly.
92% should be your answer.

4, Ecosystems
Answer:
All of these can be affected
Explanation:
A change in the Earth's climate can have a number of impacts on the planet and its inhabitants. Weather is a key aspect of climate, and a change in climate can lead to changes in patterns of weather, such as changes in the frequency or intensity of storms, droughts, or other extreme weather events. These changes can have significant impacts on plants and animals, as they may be adapted to specific types of weather and climate conditions. Ecosystems, which are complex systems of interacting plants, animals, and other organisms, can also be affected by changes in climate, as these changes can alter the relationships between different species and the availability of resources. Overall, climate change can have a range of impacts on the Earth and its inhabitants, and understanding these impacts is an important part of addressing this global challenge.
Is there an impact on the environment if blue whales went extinct?
Answer:
Yes.
Explanation:
Blue whales are the largest animals in the world, and they are the apex predator in the ocean, meaning they help to regulate the population of other species in the ecosystem. As with any species, the loss of blue whales would cause imbalances in the food chain, which would have far-reaching effects throughout the ocean and its inhabitants. In addition, blue whales help maintain the balance of carbon dioxide in the ocean which could be lost if the species were to go extinct.

Evan was 54 meters away from his car adter shopping. It took 9 seconds to push a shopping card one third of the way directly to his car at a constant velocity. What was his velocity whilehe was pushing the cart ?
The velocity while Evan was pushing the cart is 50.15m/s.
How to calculate velocity?The velocity of a moving body can be calculated using one of the following equations of motion as follows:
s = ut + ½at²
Where;
s = distanceu = velocityt = timea = accelerationAccording to this question, Evan was 54 meters away from his car after shopping. It took 9 seconds to push a shopping card one third of the way directly to his car at a constant velocity. The velocity used is as follows:
54 = (u × 9) - ½ × 9.81 × 9²
54 = 9u - 397.31
54 - 397.31 = 9u
u = 50.15m/s
Therefore, 50.15m/s is the velocity while pushing the cart.

Evan's velocity while pushing the cart towards his car would be 2 m/s.
Velocity calculationThe velocity of a moving object is the speed of the object in a specific direction. Thus, velocity is the ratio of distance covered relative to time.
Mathematically, velocity = distance/time.
Evans took a total of 9 seconds to cover 1/3 of his distance from his car.
1/3 of 54 = 18 meters.
Thus, Evan covered a distance of 18 meters in 9 seconds. His speed can be calculated as follows:
Distance = 18 meters
Time = 9 seconds
Speed = 18/9
= 2 m/s
In other words, the velocity of Evan while he was pushing the cart is 2 m/s towards his car.

Which of the following is not a good method in examining fossils anatomical features of
living organisms?
O a. Homologous structures
O b. Vestigial structures
O c.
Index fossils
O d. Analogous structures
Answer:
d. Analogous structures is not a good method in examining fossils anatomical features of living organisms.
Explanation:
Analogous structures are physical characteristics that are similar in different organisms due to convergent evolution, rather than being inherited from a common ancestor. While analogous structures can provide valuable information about the environment and adaptations of living organisms, they are not helpful in examining the fossils of ancient organisms because they do not reflect the evolutionary relationships between different species. Homologous structures, vestigial structures, and index fossils are all useful methods in examining fossil anatomy, as they can provide insights into the evolutionary relationships and characteristics of ancient organisms.

Dengue fever is an infectious disease of humans that is caused by a virus. There are four main viral strains, and an individual can never be infected by the same strain twice. However, a second infection can occur by any of the other strains. The severity of the second infection depends on the identity of both the strain that caused the first infection and the strain causing the second infection, as well as the order in which these were acquired.
Required:
How many different levels of severity are possible for an individual acquiring a second infection
Answer:
12
Explanation:
Suppose the four different strains are P, Q, R, S. Thus, the first infection can be from any of the four strains and it occurs in 4 ways.
Since an individual cannot be infected again with the strain from which he/she is been previously infected;
Then, at the second time;
The possible number of strain to be infected with = 4-1 = 3 ways
Thus; the number of possible different levels of severity can be viewed by forming two lettered word P, Q, R, and S without repetition which is:
= 4 × 3
= 12
What is the answer for Tia makes a model of a glacier with clay, sand, and an ice cube. She pushes the ice cube over the clay that is covered with sand. Explain how she could use the model to show that glaciers carry soil.
The model prepared by Tia could be used to show the glaciers which carry soil as similar to the clay which carries the ice cubes and sand, the glaciers also carry various materials along with them.
What are Glaciers?A glacier is a persistent body of dense ice and other materials that is constantly moving under its own weight and force. A glacier forms where the accumulation of snow exceeds the ablation over the period of many years, often centuries.
Glaciers acquire the distinguishing features, such as crevasses and seracs, as it slowly undergoes flow and deforms under the stresses which are induced by its own weight. As it moves constantly, it abrades rocks and debris from its substrate to create the major landforms such as cirques, moraines, or fjords. Although a glacier may flow into a waterbody, it forms only on the land surface and is distinct from that of much thinner sea ice and lake ice which form on the surface of bodies of water.

At times, a cell may be infected with a virus, or there may be an organelle within the cell that is not working any longer. A cell needs to remove such waste materials to maintain its well-being. Enzymes within the cell break down these waste materials, and the broken down materials are released from the cell. Which organelles within the cell are most responsible for processing the waste and removing it from the cell?
Answer:
Lysosomes.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles found in all living organisms such as trees, birds, and bacteria includes; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, ribosomes, chromosomes, endoplasmic reticulum, vesicles, lysosomes, etc.
Lysosomes are organelles within the cell that are most responsible for processing waste and removing it from the cell.
Basically, they are responsible for absorbing materials and breaking the materials taken in by the cells because they're typically rich in various acid hydrolases or hydrolytic enzymes such as phosphatases, lipases, nucleases, proteases, etc.

Is it possible for you to find out whether a plant has taproot or fibrous roots by looking at
the impression of its leaf on a sheet of paper? Think and explain the answer.
Answer:
No, it is not possible to determine whether a plant has taproot or fibrous roots by looking at the impression of its leaf on a sheet of paper. This is because the root system of a plant is hidden underground and cannot be seen from the surface. The shape and size of a leaf can provide clues about the type of root system a plant has, but the impression of a leaf on a sheet of paper does not provide enough information to definitively identify the type of root system.
