WHICH SPECIES OF ANIMALS ARE AFECTED THE MOST BY ACTIONS OF HUMANS IN CURRENT TIMES?SUGGEST WAYS TO PROTECT THEM.
Answers
Answer:
Polar Bears
Explanation:
The species that has most likely been the most affected by human actions would be the Polar Bears. The human population is growing at a staggering rate and this causes industrialization to expand rapidly as well. This continued and increasing use of fossil fuels for all of our basic necessities is rapidly heating up our world (Global Warming) and melting the ice caps. Without this it becomes nearly impossible for Polar bears to survive as they cannot find shelter and ultimately end up starving to death due to not being able to hunt for food as well. The only way to protect them is to begin protecting our planet, switching to more environmentally friendly sources of energy, and being mindful of our choices.

Charles Darwin took a five-year voyage around the world observing different
organisms and their adaptations. Darwin concluded that change was happening ever
so slightly in organisms, until eventually leading to a new species. What form of evolution was Darwin describing?
Answers
Answer:
Natural selection.
Explanation:
Natural selection is when organisms who are most adapted to their environment survive and pass on their genes while those with "unfit" genes die and don't get the chance to reproduce! This slowly creates a population that is most well suited to their habitat. Hope this helps again LOL! :)

describe how the chemical reactions of cellular respiration and photosynthesis keep the amount of carbon dioxide and oxygen balanced
Answers
Answer:
Cellular respiration and photosynthesis have the opposite formulas of each other. Cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O and photosynthesis is 6CO2 + 6H2O --> C6H12O6 + 6O. Because both require the products of the other equation, they are balanced.

Look again at the enzyme diagram and it’s target molecule. How might a mutation affect the interaction between the enzyme and its target and the function of the enzyme in the organism?
Answers
By viewing the enzyme diagram and its target molecule, we can infer that a mutation might affect the interaction between the enzyme and target because it may change the shape of the enzyme and consequently inhibit its function.
What is a genetic mutation?A genetic mutation can be defined as a permanent alteration in the DNA sequence that makes up a gene, which affects the production of a protein and may have a wide range of effects on the function of a cell.
Therefore, with this data, we can see that a genetic mutation may modify the protein and thus affect the reaction.

Natural selection can occur as a result of...
o genetic variation in species
o asexual reproduction in species
o competition for unlimited resources
o the gradual warming of earth
Answers
Answer:
a
Explanation:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
Answer:
Genetic variation in species
Explanation:
Natural selection is based on the idea of differential survival and reproduction. Basically this means there are genetic differences between individuals and there are too many individuals in the population to survive. The ones with the best genetic variations will survive and pass their genes on to their offspring. This doesn't happen if all organisms in the population are identical - either they all die, or they all survive.
