What is the relationship between blood vessel length and blood flow?

1 answer:

4 0

The length of a vessel is directly proportional to its resistance: the longer the veessel, the greater the resistance and the lower the flow. As with blood volume, this makes intuitive sense, since the increased surface area of the vessel will impede the flow of blood.

katrin [286]

Hypoxia is inadequate oxygen delivery to body tissues. The form of hypoxia that reflects poor oxygen delivery resulting from too few Rbcs of from Rbcs that contain abnormal or too little hemoglobin is the Anemic hypoxia. Hemoglobin plays a substantial role in carrying oxygen through out the body, and when it is deficient, anemia can result, causing anaemic hypoxia' if tissue perfusion is decreased. Iron deficiency is the most common cause of anemia.

Gametes that will be produced are:

YST, YSt, YsT, Yst, yST, ySt, ysT, yst

Explanation:

From YySsTt, it is obvious that as there 3 type of genes.

The number of gametes = $2^{3}$ = 8

5 genes = $2^{5}$ = 32 genotypes

10 genes = $2^{10}$ = 1024 genotypes

20 genes = $2^{20}$ = 1048576 genotypes

There are three ways you can solve this problem:

1.- You can guide yourself through knowledge, and therefore know the answer. There isn´t much to explain here.

2.- You can eliminate obvious options such as sarcodina or apicomplexa. Euglenoid isn´t an extremely obvious removal since it has a flagela, which can be mistook by a hairy-structure. But, if you do things correctly, obtaining your answer wont be a problem.

3.- You can do an etymologic-guess, which works really well in biology. If you guide yourself this way, you´ll bump into the answer quickly --> "cilio" means hair and according to the description the specimen was covered in hairy structures.

Hope it helped,
