Why are the cells of the alveoli so flattened?

Biology
1 answer:
Advocard [28]1 year ago
3 0

Gas exchange occurs in the alveoli of the lungs and each is made from a single layer of flat cells, Many alveoli in the lungs, so a large surface area for exchangement of C02 and O2. They are surrounded by a network of capillaries and oxygen diffuses out of them via the alveolar epithelium to the hemoglobin.

Hope this helps

After the completion of meiosis in humans, a diploid germ cell has produced cells with half the original chromosome number, gene
Andreas93 [3]

Answer: 23

Explanation:

After the completion of meiosis in humans, a diploid germ cell has produced cells with half the original chromosome number, generating 23 haploid nuclei.

Meiosis is cell division that reduces chromosome number by half. Hence, a diploid germ cell with 46 chromosomes (23 pairs) is halved to 23 nuclei at the end of meiosis, the 23 nuclei will be carried by the sex gamete

Which term best describes the macromolecule shown below? А monosaccharide В polysaccharide С amino acid D nucleic acid​
nadezda [96]

Answer:

B. Polysaccharide

Explanation:

A polysaccharide is a carbohydrate molecule made up of several units of monomers called monosaccharides linked together by glycosidic bonds. The monosaccharide is the simplest unit of a carbohydrate with the general formula, (CH2O)n.

However, the monosaccharides, which include glucose, fructose, galactose etc can link up by a bond to form a much larger carbohydrate molecule called POLYSACCHARIDE. As depicted in the image attached to this question, each ring is a monosaccharide, which becomes linked to one another to form a polymer called polysaccharide. Examples of polysaccharides are starch, glycogen, cellulose

The yellow ring inside the bacterial cell represents the bacterial DNA. Why does this structure disappear by step 3 of the lytic
adell [148]

Answer:

The bacterial DNA gets degraded at step 3 of the viral lytic cycle.

Explanation:

Viruses are organisms that are incapable of replicating on their own, hence, they require a living host which they infect and use its replicational ability to reproduce theirselves. The infection cycle of this virus is regarded as its replication cycle. Viruses employ either the LYTIC or LYSOGENIC cycle for infection.

The lytic cycle involves killing of their host cell at the end of the cycle. Generally, the cycle starts with the attachment of my the virus to the cell membrane of its host using specific receptor sites (step 1). It then penetrates the host cell as seen in step 2.

After penetration, the virus then secretes certain degrading enzymes called ENDONUCLEASES that degrades the bacterial DNA. After which the virus uses the replicational and gene expressing ability of the host to transcibe its genetic material and replicate itself. This process called SYNTHESIS occurs in step 3.

Hence, the yellow ring in the image that represents bacterial DNA disappears in step 3 (synthesis stage) because it gets degraded by viral digesting enzymes.

LiRa [457]

<h2>\boxed{Explained\:Answer}</h2>

______________________________

✿━━━━@♥ℳg━━━━✿

■Here,The corn syrup is hypertonic to the carrot, so will take water from the adjoining cells, causing those cells to shrink, become hypertonic to their neighboring cells and to take water from them.

■Conversely the water is hypotonic, and will enter the cells in the outer of the carrot.

■Because of this water will pass from the outside of the carrot to the inside, and cause liquid in the tube to rise
