Answer:

It is D

this shows that there was likely greater diversity during the time that is represented by that rock layer

it could also be random chance that those fossils ended up being fossilized in that location as fossilization is a random and rare occurence so this is usually corraborated with multiple locations

also remember that a mass extinction event can fit within as large of a window as over 100k years because dating isn't bang on and a large cataclysmic even could take a long time for it to effect the whole planet enough to cause a mass extinction

Spend one minute writing an explanation of
the FUNCTION of enzymes. YOU MUST USE
THE WORDS CATALYST, ACTIVATION
ENERGY, RECYCLABLE

Answers

Like all catalysts, enzymes work by lowering the activation energy of chemical reactions. Activation energy is the energy needed to start a chemical reaction. This is illustrated in Figure below. The biochemical reaction shown in the figure requires about three times as much activation energy without the enzyme as it does with the enzyme.

The reaction represented by this graph is a combustion reaction involving the reactants glucose (C6H12O6) and oxygen (O2). The products of the reaction are carbon dioxide (CO2) and water (H2O). Energy is also released during the reaction. The enzyme speeds up the reaction by lowering the activation energy needed for the reaction to start. Compare the activation energy with and without the enzyme

Answer:

Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.

What is the function of an enzyme? They allow chemical reactions to occur at normal body temperature fast enough to sustain life. They reduce the activation energy needed to start a chemical reaction.

There are four steps in the process of an enzyme working. (1) An enzyme and a SUBSTRATE are in the same area. The substrate is the biological molecule that the enzyme will work on. (2) The enzyme grabs onto the substrate with a special area called the ACTIVE SITE.

Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

Answers

Answer:

The birds do not breed with each other where their territories overlap.

Explanation:

The correct answer would be that the birds do not breed with each other where their territories overlap.

A species consists of organisms that are phenotypically similar and are capable of mating to produce fertile progeny.

Hence, the first thing to establish that two organisms are not of the same species is the inability to breed with each other. If an eventuality occurs and they are able to breed, the resulting progeny would be invalid.

Therefore the fact that the golden-cheeked warbler and the black-throated green warbler do not breed with each other where their territories overlap is enough information to determine that the birds are separate species.
