The answer is cross-pollination, by using parents that had different traits.
Gregor Mendel researched pea plants and he <span>established the principles of heredity. To explain his experiments and discoveries, he invented terms dominant and recessive in reference to traits. In his experiments, he used cross pollination which includes the crossing of parents with different traits. For example, he crossed a plant with green peas and a plant with yellow peas (two different traits) and studied how these traits are inherited to the next generation.</span>
<u>Answer:</u>
<em>There are innermost serious membranes that cover the heart is Parietal Pericardium.</em>
<u>Explanation:</u>
Heart is <em>covered by pericardium</em> in two sides, inner and outer sides. The inner membrane is parietal pericardium and the outer one is visceral pericardium. Pericardium is made up of <em>fiber tissues</em> that strongly protect the heart from all around.
The<em> main function of pericardium</em> is to protect the heart from any injuries and prevent the infections. The serious pericardium helps in<em> lubricating the heart. </em>
1.Gravity caused the disk-shaped nebula to shrink.
<span> A cloud of gas and dust started to shrink or more corectly started condensate, due to the force of its own gravity. This process started slow, but increased in velocity as more material were moving toward the center.</span>
2.<span>Rotational motion caused the nebula to flatten out in its disk-like shape.</span> The nebula spined counterclockwise to conserve the angular momentum of the material of the material that were going to the center. This rotation, made the materials that were not in the center flatten out, that's why it looks like a disk.
Answer:
A) protects earth's surface
Explanation:
took the test
Answer:
It means that species are selective when they are on copulation, and try to mix their genes with other individuals of its own population.
Yes, there are some exceptions like when there is not a lot of population and the individuals have to copulate with very close gene individuals to keep the species alive.
Explanation:
Gene flow has 2 important complex states and are: inbreeding and exogamy.
in Inbreeding, very close individuals from an species (Brother and sister, mother and son, father and daughter etc.) coopulate and generate new individuals, this copulation is something that doesn't help the species because stimulates recessive genes, and makes the population more susceptible to diseases.
In exogamy it's the contrary, mix genes from two individuals who are really different genitecally causes that the individuals have no common characteristics and they are more susceptible to the environment.
