Due to climate change, the range of malaria is expected to spread to areas where it was previously not a problem. Given this pie

The frequency of the sickle cell allele in areas where malaria is introduced will increase and it will be advantageous.

When a person is heterozygous for sickle cell anemia, it means it has one abnormal allele of the hemoglobin beta gene but doesn’t express the disease (like homozygous person).

On the other hand, a person heterozygotes for sickle-cell trait has a selective advantage in environments where malaria is present.

Is the reduced form of cytochrome c more likely to give up its electron to oxidized cytochrome a or cytochrome b, why? Provide a
Vadim26 [7]

Answer:

The reduced form of cytochrome c more likely to give up its electron to oxidized cytochrome a having a higher reduction potential.  

Explanation:

Electrons from NADH and FADH2 flow spontaneously from one electron carrier of the electron transport chain to the other. This occurs since the proteins of the ETC are present in the order of increasing reduction potential. The reduced cytochrome b has lower reduction potential than cytochrome c1 which in turn has a lower reduction potential than the cytochrome c.

Cytochrome c is a soluble protein and its single heme accepts an electron from cytochrome b of the Complex III. Now, cytochrome c moves to complex IV which has higher reduction potential and donates the electron to cytochrome a which in turn passes the electrons to O2 via cytochrome a3.

13.A dividing cell has a line of vesicles on the metaphase plate between the two daughter nuclei. Is it a bacterium, plant, or a
nata0808 [166]

Answer:

plant cell

Explanation:

The Golgi apparatus is a cell organelle responsible for modifying, sorting and packaging proteins and lipid molecules into vesicles (i.e., Golgi vesicles) for their delivery to targeted cell sites. A plant cell can contain many -even hundreds- of Golgi apparatus. During cell division of plant cells, Golgi vesicles combine at the metaphase plate in order to form a structure called phragmoplast. Subsequently, the cell plate formed by phragmoplast vesicles grows from the center to the cell walls. Finally, the vesicle membranes fuse to form a plasma membrane that divides the plant cell into two cells.

Why do you need to place a nylon membrane over the gel.
balu736 [363]

Who wants to attack Tartuffe, but is restrained by Dorine?
Leokris [45]
Damis, Orgon's son, wants to attack Tartuffe at the beginning of the Third Act (Scene 1). He acts irrationally and wants to prevent the marriage of his sister Marianne to Tartuffe, arranged by his father. However, the servant Dorine prevents him from acting stupid. She has another plan: they would trick Tartuffe into trying to seduce Elmire, Orgon's wife, so that he might see what a scoundrel Tartuffe really is.
