<span>A. endoskeleton
</span>Endoskeleton is not a characteristic of Arthropods that has attributed to their diversity and success. Endoskeleton is defined as inner characteristics of the skeletal feature of an organisms such as bears, humans, fish and etc.
Exoskeleton on the other hand is the trait by which arthropods posses. It is skeletal feature that is described outside or is extrinsic, this is evident as crabs have their skeletons outside of their body.
It is 200 million years because it has been around for a long time.
Answer:
C. Larger compounds break down into two or more smaller compounds.
Explanation:
During a decomposition reaction, the bonds between the atoms break down in the starting substance. The atoms then rearrange to form new bonds, resulting in new substances with properties different from the starting material.
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.
Involuntary, meaning things in the body such as your heart is all regulated to act unconsciously while also receiving directives from the brain.
