The phopholipid tail is

Biology
1 answer:
Vesna [10]3 years ago
5 0

Answer:

The phopholipid tail is hydrophobic, since it is composed of two fatty acids.

Explanation:

Phospholipids are the fat molecules that mainly compose the cell membranes, forming a double layer.

The phospholipid molecules are formed by glycerol and phosphate group, located in the head, and a tail formed by fatty acids.

The pole formed by the phosphate group is hydrophilic —since it is polar in nature— while the end formed by fatty acids, the tail, is hydrophobic.

In the plasma membrane, the hydrophobic end is located towards the surface, while the hydrophilic portion is located in the center of the lipid bilayer.

tankabanditka [31]

Answer:

1/8

Explanation:

Given that the trihybrid parents have AaBbCc genotype for fruit color. The trait is a quantitative trait i.e. each dominant allele will have an additive effect on it. In this case, AaBbCc and AABBCC will not produce same fruit color because AaBbCc has only three loci contributing to the color while in AABBCC all the six loci are contributing to the color. For an offspring to be exactly similar to the AaBbCc parents it should have the same genotype of AaBbCc.

The probability of Aa to come from a cross between Aa and Aa is 2/4 or 1/2

The probability of Bb to come from a cross between Bb and Bb is 2/4 or 1/2

The probability of Cc to come from a cross between Cc and Cc is 2/4 or 1/2

So the collective probability of AaBbCc offspring from a cross between AaBbCc and AaBbCc parents would be=

1/2 * 1/2 * 1/2 = 1/8

Hence, assuming no effects of the environment, 1/8 of the offspring will have the same fruit color phenotype as the trihybrid parent.

This question is incomplete because the images a section 2 are not given. I searched for the complete question but could not find it. However, based on my knowledge and the characteristics of the tundra this is the answer.

The correct answer is C. The climate is harsh, which limits the number of species that can live there.

Explanation

The tundra is the name of an ecosystem that occupies a fifth of the earth's surface, mainly in the northern hemisphere, this is characterized by having a frozen subsoil that limits the emergence and growth of natural vegetation and trees. This ecosystem is the coldest on the planet due to its location near the poles, its landscape is characterized by a layer of snow that covers most of the ground. In addition, the climatic conditions are extreme, which limits the number of plant and animal species that can live there. According to the above, the correct answer is C. The climate is harsh, which limits the number of species that can live there.
