Assume that the growing polypeptide chain of amino acids being produced represents an enzyme humans use to help digest starch. The original blueprint for the production of this enzyme can be found, most specifically, in the___________. A). salivary glands.
B). nuclei of gland cells..
C). ribosomes of gland cells..
D). saliva of the human mouth.

Answers

Answer:

The correct answer would be B) nuclei of gland cells.

Starch is a polysaccharide which is digested with the help of salivary amylase and pancreatic amylase in humans.

Enzymes are protein in nature and thus they must be translated from a particular gene. Genes are made up of DNA, nucleotide sequence of which is used as the blueprint for the synthesis of any protein.

This gene would be expressed in the cells of the salivary gland and pancreatic gland.

Thus, the blueprint of this enzyme can be found in the nuclei of gland cells.
I believe it's B. Nuclei of Gland Cells.

The diagram represents the ____________ formula of glucose.A)
empirical
B)
ionic
C)
molecular
D)
structural

Answers

The answer is D) Structural

That is because we can automatically cross A out, and B is not the answer because ionic compounds aren't polyatomic. Poly atomic atoms are covalent and have no charge. While on the other hand, ions have a charge.
Also, C is not the answer because the molecular formula for glucose is C6H12O6, that leaves us with choice D.

I can pretty much conclude that D is the answer because you can see that the picture, it has a structure for the compound. Its showing us how the atoms are bonded and structured. 

Answer:

answer is d) structural

Which of the following was part of the ozone depletion problem?Mining waste
Chlorofluorocarbons
DDT

Answers

The answer is Chlorofluorocarbons

Chlorofluorocarbon (CFC) is used as the aerosol propellant. An aerosol is a suspension in the gaseous form of solid or liquid particles. When these compounds reach the stratosphere, UV light affects them and they release chlorine atoms. Chlorine atoms are capable of breaking down ozone molecules. With fewer ozone molecules, the ozone layer becomes thinner and harmful UV light passes through it. 

The correct answer is B. Chlorofluorocarbons.

Besides energy, what moves through the organisms at each trophic level of an ecosystem

Answers

Besides energy biomass also moves through each tropic level of an ecosystem .

What moves through the organisms at each trophic level of an ecosystem?

Trophic levels provide a structure for understanding food chains and how energy flows through an ecosystem. At the base of the pyramid are the producers, who use photosynthesis or chemosynthesis to make their own food.

How does energy move through an ecosystem?

Energy is transferred between organisms in food webs from producers to consumers.
