1. Suppose that you take your boat offshore for a day of deep-sea fishing. You drop anchor at a supposed ‘hot spot’ and you noti
Mashcka [7]

The swim bladder is more or less an oval, soft-walled pouch located in the abdominal cavity, just below the spinal column. Its shape varies greatly, but the volume is constant between species, most often around 5% of body.

<h3>Day of deep-sea fishing</h3>

1. The volume of your swim bladder when you put it back in the water would be 7.5 liters.

2. The time the fish would float on the surface before the oval could restore neutral buoyancy would be a few seconds.

3. If I were a red blood cell that has just delivered its oxygen to the tail musculature of a mako shark, the route through the circulatory system to eventually reach the mako's swim bladder would be the venous route, like other fish, they have a heart with two chambers, an atrium and a ventricle, and closed circulation.

With this information, we can conclude that the volume of her swim bladder when she was put back in the water would be 7.5 liters.

If a man and a woman, each with sickle-cell trait, were planning to marry, what information could you provide them regarding the
kiruha [24]

Answer:

I'll inform them that the possibility of all their future children/offspring being phenotypically sickle-celled is very high.

Explanation:

Sickle cell is an inherited disease condition in which the red blood cells of the blood loses its shape and hence, dies or gets broken down. It has to do with the blood genotype of an individual. There are three major types of blood genotypes in humans namely: AA, AS, and SS. SS is the recessive genotype that codes for the sickle cell trait.

Hence, a human with the sickle cell trait has a genotype- SS. Therefore, according to this question, a man and a woman, each with sickle-cell trait (SS), were planning to marry, This will mean that both the man and the woman will always produce a gamete with S allele, which will combine to form an SS offspring. In other words, all of the offsprings of this man and woman will be sickle-celled.
