In self-pollination a plant has both reproductive structures and fertilizes itself with pollen. The offspring is identical to the parent. Which type of reproduction is this?
Answer:
Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Asexual reproduction produces plants that are genetically identical to the parent plant because no mixing of male and female gametes takes place.
Explanation:
Self-pollination is when pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) gymnosperm. Some plants have mechanisms that ensure autogamy, such as flowers that do not open (cleistogamy), or stamens that move to come into contact with the stigma. The term selfing that is often used as a synonym, is not limited to self-pollination, but also applies to other types of self-fertilization.

what role does isolation play in adaptive radiation ??
Answer:
Such exploitation of a new environment gives rise to an evolutionary pattern called adaptive radiation. Through migration, isolation, or possibly a new mutation giving rise to a brand new adaptation, a population of organisms moves into a new geographic area where that species never previously existed.
Decomposers, producers, dead matter, and consumers are all part of the ecosystem. Which part does NOT give off carbon dioxide?

Explain whether or not you expect the chaparral biome to be sensitive to the loss of a single species.
NEED HELP ASAP PLEASE!!
Answer:
Explanation:
The chaparral biome has a large amount of biodiversity, which helps insulate an environment against the loss of a single species. Therefore, one would not expect the chaparral biome to be too sensitive to the loss of a single species.

Which mechanism explains how both A and B antigens produce type AB blood?
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

Why forest and wild life are closely related
Answer:
Wildlife and Forests are heavily dependent on each other since Wildlife forms forests and helps them sustain and grow. In return, Forests provide wild organisms with food, shelter and other resources. Wildlife that live in the forest require it for survival. The forest protects them, in many cases feeds them.
