there are at least 2 million species on earth, and species have been naturally evolving and going extinct for billions of years (in fact, over 99% of all species that ever existed are now extinct!). given these facts, why do we care if human activity is driving other species extinct as we grow?

Answers

Answer 1

Answer:

This is because humans are causing species to go extinct at a faster rate than the normal rate.

Explanation:

It is documented that there are at least 2 million species on earth, and species have been naturally evolving and going extinct for billions of years. Some may say even if nothing is done there would still be extinction of this species which is true.

We care if human activity is driving other species extinct as we grow because humans are causing species to go extinct at a faster rate than the normal rate.

ATP hydrolysis _______.to ADP and Pi is the most common mechanism for transferring free energy to drive endergonic reactions

would be more exergonic if phosphate did not have resonance structures

results in products that are less solvated than the ATP

is usually in the form of ATP -> ADP Pi or ATP -> AMP PPi

Answers

Answer:

The correct answer is to ADP and Pi is the most common mechanism for transferring free energy to drive endergonic reactions.

Explanation:

Many endergonic reactions(the free energy change of these reactions are highly positive) proceed in a thermodynamically unfavorable manner.

To make those reactions thermodynamically favorable,these reactions are coupled with hydrolysis of high energy compound such as hydrolysis of ATP to ADP and Pi.

As a result the free energy change of those reactions becomes negative which allow those reactions to proceed in a thermodynamically favorable manner.

This diagram shows that embryos of certain species develop almost identically in the earliest stages of embryonic development. These physical similarities indicate that there are also genetic similarities among these organisms. The physical and genetic embryological similarities among these organisms suggest that they A. descended from a common ancestor. B. have multiple vestigial organs in common. C. are members of the same genus. D. hunt and breed in similar habitats.

Answers

The correct option is A.
The observation that the embryos of certain species have physical and genetical similarities in the earliest stages of embryonic development shows that individual development of an organism shows its revolutionary history and this is taken as an evidence of common ancestry. Scientists takes this observation to mean that all life on earth developed from a single ancestor.

Answer:

Explanation:

an example is the ability to endure the sugar, lactose, in milk. In many places of the world, people can't drink milk in light of the fact that their body turns off the intestinal creation of lactase, a chemical that processes the sugar in the milk.
