Answer:

C). Mutations sometimes improve the chances of survival for a plant.

Explanation:

Within the genome of a cell, changes occurs in the nucleotide sequence of the gene from time to time. This change is referred to as MUTATION. It occurs via mistake during replication or induced by a mutation-causing substance (mutagen). Mutations are of different types and produce different results in the cell they occur. A common type of mutation is the SUBSTITUTION mutation, which is the kind of mutation where one or more nucleotide bases are replaced by another in the sequence.

Substitution mutation will change the amino acid sequence to produce either a protein that is same as the original, or different. The different protein can either be non-functional and therefore harmful or beneficial to the cell. For example, in a plant cell, the mutation can sometimes lead to a protein that confers resistance to certain environmental stresses on the plant cell. This MUTATION can be said to have improve the chances if survival of that plant. However, it does not always occur this way. It only happens sometimes.

finlep [7]

Answer:

The correct answer is e. <em>Postzygotic barrier.</em>

Explanation:

Different species can not mate and produce viable, healthy and fertile descendence, due to certain mechanisms of <u>reproductive isolation</u>.

These mechanisms involve different kinds of barriers that make it difficult for two different species to produce viable and fertile progeny.

One of these is the <u>postzygotic barrier</u>, which avoids the hybrid zygote to develope to adultness. In these situations, there is a mix of chromosomes that can not happen to meet or that they lack information.

There are cases in which the embryo dies, but some times the individual can reach some more advanced develope stages.  If this is the case, in general, they can not survive because the organism is unhealthy. And if they reach adultness in good sate they can not leave descendence, as they are sterile.

Which statement correctly describes greenhouse gases in the atmosphere?<br>​
Nostrana [21]

Answer: It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.

Explanation:

Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.
