Answer:
Meiosis creates 4 unique haploid gametes through 2 rounds of divison.
Explanation:Gametes are created to make genetically different daughter cells.In the first round the homologous chromosomes are split so 2 cells with two chromosomes are created.In the second round the two cells undergo divison again and the chromosomes are split and 4 cells are created with half the DNA.

Your answer would be B. The reason is because the ears of any species of fox are used to keep cool, depending on the size of the fox's ears. In this case, the arctic fox is trying to stay warm, to the ears must be smaller in order to conserve heat. Hope this helps!
Answer:
The modified hemoglobin with free imidazole cannot be expected to show cooperativity in oxygen binding. The movement of iron ion takes place up in the plane of heme when binding of one subunit of hemoglobin takes place with oxygen. One of the iron's and oxygen's axial ligands comprise the proximal histidine's imidazole ring.
With the movement of iron into the hemoglobin ring, the pulling of proximal histidine takes place along with it. Therefore, when binding of oxygen takes place with one subunit, a modification also takes place in the intersubunit associations, this also comprises displacement of the alpha helix. This phenomenon plays an essential role in modifying the hemoglobin's tensed state to the relaxed state. The withdrawal or mutation of the imidazole ring from the histidine residue does not further permit the cooperative binding as it is not associated physically with the alpha-helix.

<span>Cilia and flagella are made up of microtubules covered by
plasma membrane and they projection from the cell. Thus, cilia are flagella are
motile and designed to move substances over or around the cell and they can as
well move the cell itself. In eukaryotes, they are conserved in their polypeptide
composition, structure and function as motile and sensory organelles.</span>
