What does natural selection favor?​
ratelena [41]

Answer:

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

The reason that natural selection is important is that it's the central idea, stemming from Charles Darwin and Alfred Russel Wallace, that explains design in nature. It is the one process that is responsible for the evolution of adaptations of organisms to their environment.

Which two factors of a molecule determine whether or not it can cross the membrane? A. Color and weight B. Shape and texture C.
myrzilka [38]
D. Polarity and size. 
<span>The size, polarity, and charge of a substance will determine whether or not the substance can cross the cell membrane by diffusion. The cholesterol was an example of a lipid, and is highly soluble in the nonpolar environment of the lipid bilayer. You saw, in the animation above, the cholesterol freely passing into the hydrophobic environment of the membrane. Cholesterol distributes freely in the membrane and then some fraction will dissolve in the aqueous environment of the cytoplasm. Water, on the other hand, while polar, is small enough to cross the membrane at a slow rate. Note that specialized transport proteins in certain cell membranes can provide a channel for the water, greatly increasing its rate of crossing the membrane. The lipid bilayer is much less permeable to the ion, because of its charge and larger size. As a general rule, charged molecules are much less permeable to the lipid bilayer.</span>

Two heterozygous dominant parents for attached earlobes are crossed to predict the traits of their offspring. What is the ratio
photoshop1234 [79]

Answer:

A - 3:1

Explanation:

In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.

| P | p

——————-

P | PP | Pp |

——————-

p | Pp | pp |

As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.
