The following animals generally has the lowest volume of urine production

c. Marine bony fish

All bony fish have segmented fin rays that are derived from their epidermis and sutures in their neurocranium. Both bony fish and cartilaginous fish have gills for breathing, but the gills of bony fish are protected by a hard, bony plate. Bony fish may also have prominent rays, or spines, in their fins; this characteristic is known as a "operculum".

Bony fish, in contrast to cartilaginous fish, have swim or gas bladders to control their buoyancy. On the other hand, cartilaginous fish require constant swimming to maintain buoyancy.

Based on your knowledge of reproduction in bryophytes and ferns, is the presence of flagellated sperm in cycads surprising? Why
Alisiya [41]

Answer:

The correct answer is - All plants share a similar life cycle

Explanation:

The sperms that the bryophytes are biflagellated whereas in ferns these are multi-flagellated that helps in the swimming to the archegonia or female part to perform the fertilization, due to the presence of water.

The sperms in cycads also have flagella for the same purpose of swimming in the pollen tube. The ferns and the bryophytes both require the same or similar life cycle that includes the flagella and water for the formation of the zygote.

When an inducer molecule attaches to the repressor protein what happens to the repressor protein?
faust18 [17]

The inducer deactivates the repressor protein. This allows the gene which the repressor protein suppresses, to be actively transcribed. When the inducer fits in its allosteric site on the repressor protein, the repressor changes conformation and is not able to bind the operator site of the operon.
