1 answer:

7 0

<span>Everyone has cells because these are the building blocks of life. These tiny particles that clump into groups that form tissues, organs, and organ systems are what makes organisms distinct from non-living things that exist on Earth. Where there are cells, life is present, and in its absence life cannot exist as we know of today. Cells are responsible for bringing different species of organisms that are found in different ecosystems all over Earth. They are tiny but in groups they are responsible for every living organisms that have existed through time. </span>

As blood moves away from the heart toward the tissues, the relative size of blood vessels ________, the blood pressure ________,

KonstantinChe [14]

<span>As blood moves away from the heart toward the tissues, the relative size of blood vessels decreases, the blood pressure drops, and the velocity of blood flow slows.

The size of the arteries progressively decreases as they branch out from the major arteries of the body. Once the arteries are the size of the arterioles, the resistance to blood flow increases and velocity of blood flow slows then blood pressure drops.

Fireflies emit flashes of light because of chemical reactions, which occur in their abdomens. The rate of the chemical reactions

damaskus [11]

Since the rate of flashing depends on the rate of reaction, it means that fireflies will flash slower during cold weather.

<h3>How does temperature affect rate of reactions?</h3>

Temperature affects the rate of reaction such that reactions are faster at high temperatures and slower at low temperatures.

Thus, since the rate of flashing in fireflies depends on the rate of reaction, cold temperature means that the rate of flashing will be low as compared to warm temperature.

In other words, fireflies will flash lower during cold weather and vice versa.

51. how do the differences in amino acid sequences lead to different protein functions?

Setler [38]

DifferentDifferent amino acid produce different proteins based on the bonds formed between them .

<h3>How does the sequence of amino acids affect the functions of protein ? </h3>

The sequence of amino acid of a protein determines protein shape , since the chemical properties of each amino acids are forces that gives rise to intermolecular interaction to begin to create secondary structure .

Amino acids are monomers of protein. So , different amino acids produce different proteins based on the bonds formed between them.
