➷ The correct answer would be D. Products of one process are used as some of the reactants for the other processes.

As you may know, the formula for photosynthesis is:

carbon dioxide + water ==> oxygen + glucose

And the formula for respiration is:

oxygen + glucose ==> carbon dioxide + water

The reactants for one are the products for the other and vice versa. This is why it would be the correct option.

Many subcortical structures, such as the hippocampus and amygdala, come in groups of two. why?

lions [1.4K]

The right answer is a.anatomy involves symmetry.

In the anatomy of multicellular animals with bilateral symmetry (which form the subregion of bilateria), there are many even organs, that is to say composed of two symmetrical halves, generally positioned on both sides of the median plane. This is the case, for example the human brain that includes two hemispheres, two amygdalas and two hyppocampus, a left and a right.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

<em>In any one species, the amount of adenine closely approximates that of thymine. </em>
<em>In any one species, the amount of guanine closely approximates that of cytosine. </em>
<em>The amounts of A, T, G, and C in DNA varies from species to species. </em>

<em>(options A, B and D)</em>

Explanation:

Organizing the data has to:

<u>Source of DNA A T G C </u>

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

Which is NOT a characteristic of a plant? multicellular eukaryotes have chloroplasts mobility

murzikaleks [220]

<span>Among all choices, mobility is not a characteristic of a plant. Plants are multicellular organisms. They have organelles inside their cells and thus they are eukaryotes. Chloroplasts are organelles that are found in plant cells and they have an important role in the process of photosynthesis. However, plants cannot move from place from place like animals.</span>

What is expected to happen to the sac containing the distilled water in the sugar solution? Will it shrink or expand? Explain yo

Drupady [299]

Answer:

Expand. Distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container. Thus, distilled water is a type of purified water.
