The processes of mitosis and meiosis performed in a multicellular organism are mitosis creates indentical genetic copies of cells and meiosis creates haploid gametes. this is what make multicelllar organisms grow larger and repair damage.

Human blood groups are governed by three alleles, IA, IB, and i. IA and IB are codominant and i is recessive to both. A man who
tangare [24]

Answer:

The correct answer is e. all of the above

Explanation:

A person can only have two allele of a character, therefore, the genotype of a male parent can be IBIB or IBi and the genotype of female parent can be IAIA or IAi. Therefore during gamete formation, all allele will segregate and assort independently.

So all the possible combinations are possible that are  IAIB, IAi, IBi or ii because all the allele can be present in the two parents in which one have A blood group and another have B blood group.

Therefore their children could have A, B, AB, or O blood group so the correct answer is e. all of the above.

How is oxygen different from hemoglobin
Alex777 [14]

Answer:

This is because the hemoglobin molecule changes its shape, or conformation, as oxygen binds. The fourth oxygen is then more difficult to bind. The binding of oxygen to hemoglobin can be plotted as a function of the partial pressure of oxygen in the blood (x-axis) versus the relative Hb-oxygen saturation (y-axis).Explanation:

Identify which type of natural selection is described in each case below.
ICE Princess25 [194]

Answer:

Results in the evolution of the species: Directional selection

Results in new species: Disruptive selection

Favors traits at the two extremes: Disruptive selection

No increase in diversity: Directional selection

One extreme trait is favored: Directional selection

Diversity decreases: Stabilizing selection

Diversity increases: Disruptive selection

Explanation:

Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.

Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.

While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
