List the structures of a sperm. (Module 26.3C) List the structures of a sperm. (Module 26.3C) acrosome, head, cilia, and flagell
Mademuasel [1]

Answer:

I think your question is poorly worded, just like all the parts are: a head and its flagellum, but within them we can distinguish several structures, which, in cephalad-caudal order (from head to tail, that is, from top down), son: acrosome, nucleus, membrane, neck, middle piece, tail and end piece.

Explanation:

Sperm are zygote cells that have half the genetic load, which is why when they join the ovum in fertilization, they form the complete genetics of the human.

In turn, the sperm has very efficient mechanisms for obtaining rapid energy, since they consume many ATP molecules when inoculating the ovum during fertilization.

They are formed by with the help of the sertoli cell, which sets the physiological state so that in the human testicle they are formed releasing in the male semen.

A ____ fish controls the concentration of salt in its body by actively excreting salt across its gills, drinking, and producing
kvv77 [185]

Answer:

The answer is hyper-tonic.

Explanation:

The hyper-tonic fishes are found in freshwater. In these fishes, their blood conveys a lower water focus than the encompassing freshwater. With the death of freshwater by means of the mouth over the layers of the gill, the particles of water diffuse from the freshwater into the blood as a natural side effect.  These fishes need to create an extremely tremendous amount of pee to offset this abundant utilization of water. These fishes therefore deliver little measures of concentrated pee.
