Stomata- specialized cells that contract and expand to open or close pores for gas exchange. Stomata can adjust to temperature,

Answer:

CLOSED.

Explanation:

Stomata are found in epidermal layers in green aerial parts of plants, especially leaves. They occur mainly on the lower surface of dicotyledonous leaves, although on monocotyledonous, they are found on both surfaces. Intercellular air spaces found throughout the leaf are linked to stomata.

Stomata permits plant uptake of carbon dioxide, which is a necessity for photosynthetic processes. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.

Therefore, it can be said that Stomata adjust temperature, staying closed when temperatures are hot and dry.

It is an example of directional selection.

The different kinds of natural selection can influence the distribution of phenotypes within a population. In stabilizing selection, an average phenotype is preferred.

In directional selection, a modification in the surrounding changes the spectrum of the observed phenotypes, and in diversifying selection the extreme values for a trait are preferred over the transitional values. This kind of selection usually pushes speciation.

The directional selection, in the field of population genetics, refers to a mode of natural selection in which an extreme phenotype is preferred over other phenotypes, making the allele frequency to change with time in the orientation of that phenotype.

Prokaroytic and eukarayotic cells
asambeis [7]

Answer:

A prokaryote is a cellular organism that lacks an envelope-enclosed nucleus. The word prokaryote comes from the Greek πρό and κάρυον. In the two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota.Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals. These organisms are grouped into the biological domain Eukaryota.

Rina8888 [55]

The question is incomplete. The complete question is:

Question: A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white corn results in ears of corn that have an approximately even mix of yellow and white kernels. Which term best describes the relationship between the two alleles?

a) Incomplete dominance

b) Genetic recombination

c) Chimerism

d) Codominance

Answer:

d) codominance

Explanation:

Codominance is a pattern of inheritance when none of the alleles of a gene is able to mask the expression of the other allele of the same gene. When the two alleles are present together in a heterozygous genotype, both are expressed and the phenotype of the heterozygote is different from both the pure breeding parents. In the given example, cross-pollination of yellow corn and white corn results in the ears of corn that have an approximately even mix of yellow and white kernels. This means that the heterozygote expresses both the allele for the corn color. Therefore, it represents codominance.
