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?

Answers

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.

Which mechanism explains how both A and B antigens produce type AB blood?

Answers

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.

. A protease is added to a suspension of egg protein in a test-tube and kept at 37°C. After 8 minutes, the protein changes from cloudy to transparent. Which product, or products, will now be present in the test-tube

Answers

Answer:

amino acids

Explanation:

A protease is an enzyme capable of catalyzing the breakdown of proteins into polypeptide fragments and single amino acids, which are the building block of proteins. Proteases act by breaking peptide bonds by a process called hydrolysis, a reaction where water molecules break down peptide bonds (hydro means water and lysis means split). Proteases can be classified depending on the catalytic residue into cysteine, serine, threonine, aspartic, glutamic and metalloproteases.

The product that will be present in the test tube will be amino acids.

Protease is an enzyme that acts on protein by converting it into different

types of amino acids.

Amino acids are referred to as the building block of life and are important

nutrients in growth and replacement of worn-out tissues. The protease acts

on the protein by breaking the peptide bonds under the required

temperature.

An inadequate temperature may result in the denaturing of the enzyme

which was why the test was done at 37°C. This is the body temperature of

humans which led to the formation of amino acids which is absorbed by cells

of the body.
