zlopas [31]

Answer:

A series of nonpolar amino acids would most likely be located in the interior region of the tridimensional molecule.

Explanation:

Proteins are formed by linearly arranged amino acids, each with a side chain: the R-group.

Of the 20 different amino acids that compose the proteins, about half of them -10- are non-polar. Their R-groups are not stable if they are in contact with water, meaning that non-polar amino acids are hydrophobic.

When proteins are synthesized, they acquire a three-dimensional structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. When they are in an aqueous media, their bent shape leaves the hydrophilic R-groups in contact with water. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water.

What information did you include in our<br> response?
Daniel [21]

Answer:

All of the statements are true.

The X chromosome is one of the two sex chromosomes of humans and some animals (the other sex chromosome is the Y chromosome). Men have a single X chromosome and women two X chromosomes.

Diseases whose gene is localized on the X chromosome are most often transmitted in the X-linked recessive mode; some are transmitted on the dominant mode related to the X.

In this mode of inheritance, the morbid allele behaves like a recessive trait.

Women heterozygotes are not affected but can transmit the disease; they are aid to be conductive of the disease.

The disese is only manifested in male subjects (XY) with only one copy of the gene (hemizygous subjects)

Kruka [31]

Answer:

Option B, It increases the probability that some offspring will survive long enough to reproduce.

Explanation:

The larger the number of eggs, the larger will be the available opportunities for at least few of the youngsters to develop into adult being and survive till the age of fertility. This shall enhance the chances of producing new offspring before the older  one dies thereby replacing them without changing the population number and further producing offspring that can survive to replace them and continue this chain.

Hence, option B is correct

Keystone predators can maintain species diversity in a community if they _________. A. competitively exclude other predators B.
Alisiya [41]

Keystone predators can maintain species diversity in a community if they  prey on the community's dominant species

Option B is correct.

What is meant by keystone predator?

A keystone species is usually a dominant predator whose removal allows a prey population to explode and often decreases overall diversity. other forms of keystone species are those, like coral or beavers, that significantly alter the habitat around them and thus affect large numbers of other organisms.

Are keystone species always predators?

A keystone species is usually , but not always, a predator. Just some predators can control the distribution and population of large numbers of prey species. the whole concept of keystone species was founded on research surrounding the influence of a marine predator on its environment.
