Explanation:
By gene pool definition it says genetics are pass on throughout a population.( one can say humans or any other type of organism that's the same species)
Describe the scientific explanations of the origin of life of Earth.
The scientific experiment on the origin of life on earth is according to the RNA world hypothesis, which is supported by many scientists, RNA rather than DNA was the earliest genetic molecule of life on Earth.
What is the origin of life on earth?The natural process through which life emerges from non-living materials, such as simple organic compounds, is known as abiogenesis or biopoiesis. Abiogenesis theories can be broken down into three basic stages: geophysical, chemical, and biological. Therefore, biogenesis, protobiogenesis, and biopoiesis are other terms for the origin of life.
Although the signature traits of living systems are explained by the creation of a self-replicating catalytic enzyme, the origin of the photobiological molecule itself is not explained.
Therefore, according to a scientific experiment on the genesis of life on Earth, RNA rather than DNA was the first genetic molecule of life on Earth.

Where can you find the DNA in a eukaryotic cell? Where can you find the DNA in a prokaryotic cell?
Answer:
first question:The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms
:second question: The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane.

The United States is often called the "melting pot" because people from all nations have made a home here. If someone has a grandmother from Brazil, for example, that came to live in the US, would relocating to Chicago change her grandkids’ skin tone phenotype? Why or why not?
Answer:
Technically no
Explanation:
Technically no. The skin tone of the individual is caused by two factors, one is genetic and the other is environmental. The genetic factor will continue being there since the grandkids would be descendants of the grandmother. The environmental factor can change skin tone phenotype over the course of an individual's life. Although in this scenario, both locations have the same type of weather. Both Brazil and California are incredibly hot locations all year round.

Sustainable forestry: seeks to conserve forests for the long-term commercial harvest of timber and non-timber forest products by maintaining a mix of forest trees, by age and species, rather than imposing a monoculture. due to the complexity of goals, is most effective when it involves cooperation among environmentalists, loggers, farmers, indigenous peoples, and local, state, and federal governments. approaches vary from one forest ecosystem to another, in response to different environmental, cultural, and economic conditions. is all of the above.
Answer:
Yes, it is all of the above.
Explanation:
Yes, all the above statements are necessary for sustainable forestry because trees and other wild plants of the forest are necessary for all farmers, loggers, environmentalists, indigenous peoples and for the governments. The environmentalists study on these plants to find out the impact of these different plants on the environment, the farmers cultivate trees and plants to get money by selling it, the employment of loggers also related to these forests and the indigenous peoples also gain benefits by gaining food as well as medicines from it. This forest also fulfill the needs of wood and other products of the country.

An enzyme
Please help!!!
Answer:
Enzyme molecules are made up of one or more amino acid chains. The sequence of these chains is what specifies different enzymes. These long chains fold up into unique shapes which allows the enzyme to carry out chemical reactions, this varies based on the type of enzyme.
Enzymes speed up chemical reactions in the body that help keep us alive, for example, enzymes help with multiple things such as digestion, growth, healing, reproduction, etc.

Answer/Explanation:
Using body systems respiratory, circulatory, and muscle.
The respiratory, circulatory, and muscle work together because the circulatory carries blood to the muscles and respiratory systems. The respiratory systems gives breathe and makes it able to live so the other two can function. The muscle systems helps move using the breath of life and the blood from the circulatory.

why would you expect Greenland to have a higher albedo than its surrounding areas?
The albedo of the ice sheet is high in winter when much of Greenland is covered by fresh snow.
Greenland is filled with ice and has a higher reflectance rate as in winters it's covered with fresh snow.
Where is Greenland?The greenland is an island nation and lies between the arctic and Atlantic ocean. Has an area of 2.166 million square km and is among the largest island in the world.
It has the third-largest area in North America after Canada, The lowest temperature is recorded in Greenland in the northern hemispheres. Greenland is Greenland snow is thick and fresh in winter this creates a higher albedo.
