Answer:

Here are the options to complete the question

A. Fenestrated capillaries

B. continuous capillaries

C. sinusoids

D. anastomoses

A. Fenestrated capillaries is our Sure ANSWER

Explanation:

Fenestrated capillaries (is located wherever active capillary absorption or filtration occurs)

The renal glomerulus - a network of capillaries - can be identified as fenestrated capillaries aiding the diffusion of small molecules and small amount of protein into the blood stream.

In a certain group of African people, 4% are born with sickle-cell disease, an autosomal recessive disorder. Heterozygous indivi

love history [14]

Answer:

the correct answer is C) 32%

Explanation:

Sickle-cell anaemia is an autosomal recessive genetic disorder. Individuals with the homozygous recessive have sickle-shaped blood cells. Whereas, individuals with heterozygous are only carrier of sickle cell trait. The carrier individuals are resistant to malarial parasite and do not have malaria.

As per the question, 4% of an African population is born with sickle-cell disease, then the percentage of the population is heterozygous and resistant to malaria will be:

Hardy-Weinberg formula is equilibrium,

p² + 2pq + q² = 1

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p2 = percentage of homozygous dominant individuals

q2 = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

Given, homozygous recessive for this gene (q2) is 4% which is 0.04, the square root (q) is 0.2 (20%) then p should be 1-0.2 = 0.8 (20%).

Thus, the frequency of heterozygous individuals = 2pq.

2 (0.8 x 0.2) = 0.32 (32%).

(b) Describe the characteristics of the interior of the aquaporin channel protein that allow water to flow through AND exclude g

Valentin [98]

Answer:

Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices.

Explanation:

Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices. These aquaporin protein have different size of water channels that allow water through to pass through it but it does not allow glucose to move through it due to its large size. The direction of water movement is toward the cell because there is low water inside the cell as compared to outside environment so the water moves inside the cell and rate of water movement slows down over time due to filling of empty spaces with water.

To study cells with a light microscope different types of stains are usually available. why is it generally more useful to stain

kari74 [83]

<span>Cells are difficult to see in light microscopy,so to help visualize the structure of cell ,dyes are used to impart a particular color to cells. Eukaryotic cells have both acidic and basic components so, Hematoxylin and Eosin staining is the standard method of staining used for an eukaryotic cell. Hematoxylin is a basic dye that binds to negatively charged DNA and RNA and is blue in colour.Eosin is pink in color and it binds to positively charged particles like the mitochondria and other components of cytoplasm.</span>
