Answer:

A hydrogen bond is a type of attractive (dipole-dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This bond always involves a hydrogen atom. Hydrogen bonds can occur between molecules or within parts of a single molecule.

Answer:

The correct answer is "Yamnaya".

Explanation:

In genetics, a population or genetic bottleneck is defined as a reduction on the size of a population as a result of an environmental effect or human intervention. Regarding the Y chromosome bottleneck, the Yamnaya is an ancient population that contributed the most due to its sex-biased and stratified culture. The Yamnaya were violent and left behind many male skeletons, where just few type of persons were able to reproduce.

Answer:

Its fossil energy non renewable source

Explanation:

Answer:

Coal vs Natural Gas             Coal is a sedimentary rock with a high concentration of hydrocarbons and carbon. Given that it takes millions of years for coal to develop, it is categorized as a nonrenewable energy source. Coal is combustible and typically black or brownish black in color. Natural gas is a naturally occurring mixture of gaseous hydrocarbons, mostly methane, with small traces of other higher alkanes. Coal and natural gas have different benefits, effects on the Earth, and impacts on human health.             Natural gas is a fossil fuel; however its global warming emissions are significantly smaller compared to those from coal or oil. When combusted in a modern, efficient natural gas-power plant, natural gas releases between 50 and 60 percent less carbon dioxide (CO2) than pollution from an average modern coal plant. The impacts of human health due to air pollution from both coal and natural gas can lead to asthma and breathing issues, brain damage, heart problems, cancer, neurological disorders, and early mortality. These conditions are from the releasing of mercury, lead, sulfur dioxide, nitrogen oxides, particulates, and other heavy metals in to the air. In 2021, electricity producers in the United States paid roughly $4.98 per million British thermal units for natural gas. Coal power plant operators, on the other hand, paid an average of 1.98 US dollars; in simpler terms, the cost of generating electricity is cheaper using coal.             Coal is a reliable, cheap source of power. It is easy to store, reduces dependence on oil, and creates many jobs.  On the other hand, when burned to create power, natural gas produces roughly half the carbon dioxide (CO2) and one-tenth the air pollutants produced by coal. By using gas instead of coal, there is significant potential to cut near-term CO2 emissions and air pollution by using gas over coal.  It is adaptive. A gas-fired power plant starts and stops much faster than a coal-fired unit. Both gas and coal have plentiful pros and cons however gas is the better one to use. Gas is more abundant and pollutes more than coal. Though coal is cheaper, the effects on the environment and human health are not worth the gamble.               https://www.shell.com/energy-and-innovation/natural-gas/natural-gas-and-its-advantages.html  http://groundtruthtrekking.org/Reports/Coal-Electricity-Prices-Externalities-Analysis/1/Coal-Electricity-Prices-Externalities-Levelized-Cost/ https://www.statista.com/statistics/189180/natural-gas-vis-a-vis-coal-prices/

Answer:

1. False

2. True

3. False

4. False

5. False

6. True

Explanation:

1. Remember, the term Genetic diseases implies that they are diseases inherited genetically. Thus, environmental conditions have no direct influence on the spread of genetic diseases.

2. We can make this conclusion because research has shown that genetic disorders are more common in families with one affected member as compared to the general population. In other words, the family's medical history is part of the determinant factor.

3. Some recent studies have shown that both members of identical and fraternal twin pairs do not have the same likelihood of expressing the same genetic disease.

4. Genetic diseases do not occur at the same rate in all human populations.  Researchers often make reference to findings discovered from surviving victims of the Hiroshima nuclear bomb which is said to be the cause of some genetic diseases. Also, the sickle cell genetic disease rate of occurrence is believed to be high in Africa than in North America.

5. Scientists believe that there is no specific age of onset of genetic disease. That is to say, they may appear within an age range but not a specific age.

6. Indeed, many human and animal genetic disorders share similar characteristics . A good example is the albino genetic order in humans has been discovered to share similar characteristics that is found in animals.

Answer:

Over-watering severely limits, even cuts off the supply of oxygen that roots depend on to function properly, meaning that plants do not get adequate oxygen to survive. Furthermore, too much water can also lead to root rotting and the irreversible decay of roots.

Explanation:

Answer:

d. ​Very small cells are the best adapted for nutrient exchange.

Explanation:

The need to be able to pass nutrients and other substances into and out of the cell limits how big cells can get. The larger a cell is, the more difficult it is for nutrients and gases to move in and out of the cell because the volume is larger than the surface area. Smaller cells can exchange nutrients with the external environment more quickly.

Explanation:

Trypsin is a serine protease enzyme capable of hydrolyzing different types of proteins. This enzyme is used in biotechnology and molecular biology to hydrolyze at the carboxyl side of arginine or lysine residues. Moreover, chymotrypsin is another digestive protease that also catalyzes the breakdown of proteins into small polypeptide chains. This enzyme cuts the C-terminal side of aromatic amino acids such as tryptophan (W), tyrosine (Y) and phenylalanine (F) on peptide chains.

Answer:

  Reproductive strategies are not an either/or sort of affair; some organisms fall somewhere between semelparity and iteroparity reproduction. In addition to various reproductive strategies, organisms differ in their survivorship strategies. Some organisms are at high risk of dying early in life, but if they can survive long enough, they have a decreasing probability of dying as the years go on. Well, to a point anyway. Other organisms have a steadily increasing probability of dying while still others live for a long time with the probability of dying only increasing dramatically after a certain (often old) age.

Answer:

Autosomal dominant inheritance: A person affected by an autosomal dominant disorder has a 50 percent chance of passing the mutated gene to each child. The chance that a child will not inherit the mutated gene is also 50 percent. However, in some cases an autosomal dominant disorder results from a new mutation that occurs during the formation of egg or sperm cells or early in embryonic development. In these cases, the child's parents are unaffected, but the child may pass on the condition to his or her own children.

Answer:

Light-dependent

Light-independent

Explanation

The light-dependent reactions of photosynthesis require energy from the sun to split a molecule of water into hydrogen and oxygen. The oxygen is released and the hydrogen ions are used as energy for the next steps, as is ATP.

In  the light independent reactions, sugar is made from carbon dioxide using the energy from the light-dependent steps

Answer: C - Most of the energy collected by an organism is not passed on to other organisms.

Explanation:

right on edge 2020

also only 10% of energy is transferred to the next trophic level

The best description of energy transformation in an ecosystem is most of the energy collected by an organism is not passed on to the other organisms. Thus, the correct option is C.

Energy is transferred between different organisms in a food web from producers to different consumers. The energy is used by the organisms to carry out most of the complex tasks in the food web. The vast majority of energy which exists in a food web originates from the sun and is transformed into chemical energy by the process of photosynthesis in the plants.

Energy transformation in an ecosystem follows 10% law, where only 10% of the energy is transferred to the next trophic level in an ecosystem. Thus, most of the energy collected by an organism is not passed on to other organisms.

Therefore, the correct option is C.
