If you want a description of Bryophyte or how it looks like is that:
It is a small green plant that is flowerless and consists of Mosses and Liverworts. It can also be referred as Embrophytes.
Answer:
Environmental factors can influence natural selection because they can increase or decrease the amount of genetic variation in a population.
Explanation:
Natural selection is a process that involves the survival of species through changes in the expression of their genes, making possible the process of adaptation to environmental changes. It is one of the explanations for the biological evolution of species.
The second premise, necessary for natural selection to be possible, implies the existence of a variability (genetics) of traits among individuals in a population.
The other premises of natural selection are the faculty of traits to be inheritable and that genetic variability should lead to reproductive success and survival.
- <em>The other options are not related to the process of natural selection, since it is not possible for natural selection to increase or decrease the number of chromosomes, in addition to the fact that genetic variability must be observed in a population, not in a single individual, to be considered natural selection </em>
Finches recognise individuals of their species based on appearance and songs. More specifically, finches differences in appearance that they can recognise include the body colour, size and shape. Concerning the songs that they sing, they are significant differences between the song that each species sing.
Unfortunately this question is incomplete as it is a multiple choice question. The following options are provided:
<span>A) body cavity between body wall and digestive system
B) number of embryonic tissue layers
C) type of body symmetry
D) presence of Hox genes
E) degree of cephalization
The answer is D: presence of Hox genes

Hox genes are a group of genes that determine the basic structure and orientation of animals.
Erosion is brought about by the forces of nature or human activity: water, wind, earthquakes, mining, quarrying, etc. In the desert, there is very little water that can cause weathering or erosion, so the most probable answer is wind or maybe even animal activity.
