16. Niles Eldredge found evidence in trilobite fossils of a pattern of evolution in which short periods of large change are mixed in with longer periods of little or no change. This pattern is called WHAT.
I think it is punctuated equilibrium, but not sure.
PLEASE ONLY ANSWER IF YOU KNOW THEY ARE CORRECT!!!!
organs
striated muscles
cardiac muscles
i know this is late but the correct answer is the cardiac muscles
b. fish and birds in freshwater habitats dying off
c. people receiving acid burns on there skin
d. whales and dolphins dying off in the oceans
A situation that is commonly caused by acid rain is the dying off of fish and birds in freshwater habitats. Thus, the correct option for this question is B.
Acid rain may be defined as a type of precipitation that correspondingly include acidic components, like sulfuric acid, nitric acid, etc. that fall to the ground from the atmosphere in wet or dry forms like rain, fog, hail, etc.
The pH of acid rain is generally low compared to normal water. So, it causes numerous impacts on the earth's surface. But the most consequential influence of acid rain is the destruction of fish and birds in freshwater habitats.
It generally lowers the pH of the freshwater ecosystem and makes it unfavorable for many organisms like producers, small fishes, birds, etc. They cannot adapt themselves to such lower pH and have to dye off.
Therefore, the correct option for this question is B.

Answer:
The correct answer would be the skeletal system, muscular system, and nervous system.
The skeletal and muscular systems are involved in making any kind of movement as well as maintaining the body posture.
The nervous system control and coordinate the movement and posture of the body.
The nervous system controls the skeletal muscles to produce movement.
Skeletal muscles are connected to the skeletal system of the body. Thus, ultimately they produce movement in the skeletal system.
Endothermic reaction
Exothermic reaction
Endothermic reaction
An endothermic reaction is those reactions that take up energy from the environment as that proceeds. The opposite is an exothermic reaction that gives off energy to the environment.
Explanation:
When cooking an egg you require energy to break down the interactions between the protein chains and atoms of the raw egg so they are rearranged into a cooked egg. This is akin to the denaturing of proteins. Cooking food helps ease their digestion. Because we need energy to break down the interactions and bonds of the proteins in the egg this is why we use fire in cooking. This is, therefore, an endothermic reaction.
