Answer:

Simple epithelium is a single layer of cells with every cell in direct contact with the basement membrane that separates it from the underlying connective tissue. In general, it is found where absorption and filtration occur. The thinness of the epithelial barrier facilitates these processes.

Why does the exchange of gases between blood and body tissues not occur through the walls of arteries?
Novosadov [1.4K]

Explanation:

Capillaries are thinnest blood vessels there are in human body or basically in any multicellular living creature. Capillaries are so thin, they are like a sheet made of cells. So there is nothing like capillaries which can introduce blood with the materials to be absorbed without letting both of them mix directly. Arteries and veins are too thick to carry out such exchange.

If you have a pet cockroach with a brown body, how could you find out if it is
aleksklad [387]

Answer:

by testcrossing with a homozygous recessive partner

Explanation:

<u>If a pet cockroach exists whose zygosity is unknown, this can be determined by a test cross. A test cross involves crossing an organisms whose zygosity is unknown with a partner that is homozygous recessive for the same trait.</u>

Let us assume that brown body is represented by the allele B, the dominant allele. The homozygous recessive version would be bb.

The genotype of a brown cockroach whose zygosity is not known can be denoted as B_, where '_' can be a 'B' or a 'b'.

When B_ is crossed with bb:

B_   x   bb

Progeny

2 Bb

2 _b

The phenotype of Bb would be brown (since B is dominant over b) while the phenotype of _b would depend on the zygosity level of the cockroach.

If the unknown genotype is BB, then _b becomes Bb and the phenotype will be a brown body. This means that all the progeny will appear brown. (<em>see the first attached image for the Punnet's square</em>)

In other word, if the unknown genotype is bb, then _b becomes bb and the phenotype will be a alternate color (non-brown) body. This means that 50% of the progeny will appear brown while the remaining 50% will be in the alternate color. (<em>attached</em>
