Why have food prices been a more serious problem than food supply?

Biology
1 answer:
dem82 [27]3 years ago
4 0
Because food prices are very high and some people can not afford them. And food supply is way up high so they don't have to worry about how much food is being made. They have to worry about the prices to make sure that they are reasonable enough for people to have money to buy them so that they won't starve to death.

How do stabilizing and disruptive selection differ? how do stabilizing and disruptive selection differ?
skelet666 [1.2K]

Disruptive selection is made of natural selection which favor both extreme phenotype and both  from one extreme in directional selection. Stabilizing selection is favors the middle phenotype, average trait value over two extreme trait values.

Both the selection are disruptive selection favors phenotype while stabilizing selection favors average phenotype in population , eliminating both extreme.Disruptive selection also known as diversifying selection.

Stabilizing selection is natural selection pursue population towards the average or median . Normally environment favors average phenotype within a population.Both are two natural selection , affect the distribution of phenotype within a population,Applies to  a phenotype trait.

Species in which dark brown fur (D) is dominant relative to light brown fur (d). Using the Punnett square below, predict the fre
Debora [2.8K]

Answer:

<h3>Genotype frequencies</h3>

25% DD

50% Dd

25% dd

or

1 DD: 2 Dd: 1 dd

<h3>Phenotype frequencies</h3>

75% Dark brown, 25% light brown

or 3 dark brown: 1 light brown

Explanation:

Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.

           D                   d

D        DD                 Dd

d        <em>Dd                  dd</em>

<em />

25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown,  since it has two copies of the dark brown fur allele (DD)

50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown  fur (d).

25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)

abruzzese [7]

The correct answer is the mesophyll tissue from a leaf.

The mesophyll is the term given to the two cell layers present within the leaves of a plant. The first layer is situated within the epidermis but above the second layer. The second layer is the palisade parenchyma cells.

The palisade layer is loaded with ample of chloroplasts, making it the layer most directly accountable for photosynthesis. These chloroplasts absorb the maximum part of the light energy utilized by the leaf.
