Estelle makes a Venn diagram to compare the fast- and slow-flowing areas of rivers and streams.
Olegator [25]

Image is not provided in the question, so the image is attached below.

Answer:

Fewer plants

Explanation:

The region X in Venn diagram represents fewer plants in the region.

As the regions marked X represents  fast-flowing areas of rivers and streams which can be possible if the flow of water get less obstruction in its way, so if their will be fewer plants, river will get less resistance and can flow faster.

Other option do not affects the flow of water.

Hence, the correct option is fewer plants.

For the following biomolecular interactions, choose the main weak force interactions that mediates them.
Juliette [100K]

Answer:

Interaction between hydrophobic (nonpolar) amino acid side chains is due to hydrophobic interactions.

Repulsion between negatively charged backbone of DNA double helix is due to electrostatic repulsion forces.

Interaction between water and carbonyl oxygen of guanine is due hydrogen bonding

Explanation:

The hydrophobic effect refers to the tendency of non-polar substances forms aggregates in an aqueous solutions in order to avoid interactions with water molecules. This results in a favorable entropy increase.

For non-polar amino acids, hydrophobic interactions are important in stabilizing their structure wherein they are densely packed within the core of a protein while those with with polar groups are found in the exterior.

The phosphate backbone of DNA is negatively charged. Since like charges repel, therefore, electrostatic repulsion forces of the ions are responsible the repulsion of the backbone DNA double helix.

Hydrogen bonds are formed between electronegative oxygen atoms and hydrogen atoms of neighboring molecules due to the partial negative and positive charges on each of the atoms.

This hydrogen bonding is responsible for the interaction between water and carbonyl oxygen of guanine as the hydrogen atoms of the water molecules are attracted to the oxygen atoms of the guanine molecules due to the partial charges on each of the atoms.

Giacomo, Brian, and Barbara have each consumed two margaritas during the last two hours. If Giacomo weighs 176 pounds and both B
sergey [27]

Answer:

The correct answer is - Barbara.

Explanation:

BAC or basic alcohol concentration is vary in male to female as females are smaller than men so the total blood is less than the men even the weight is same in both.

This the cause that affects the females to get impaired more than the males and easily get intoxicated even though the weight and amount of the alcohol is similar.

Thus, the correct answer is - Barbara.
