Consider this situation: you want to reabsorb sodium ions but you do not want to increase the volume of the blood by reabsorbing

choli [55]

Answer:

Increase aldosterone and decrease ADH

Explanation:

Aldosterone causes reabsorption of sodium ions while Antidiuretic hormone (ADH) causes reabsorption of water. Aldosterone also causes water reabsorption due to increased osmotic pressure by reabsorbing sodium ions. But for water reabsorption, Aldosterone has to work along with ADH to increase permeability for water. If we increase Aldosterone and decrease ADH, the sodium ions will be reabsorbed while water cannot be reabsorbed due to decreased permeability of DCT and collecting tubules for water.

The sporophyte of an unknown plant species grows as a separate plant than the gametophyte. The plant produces both female and fl

N76 [4]

Answer:

The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".

Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.

They show alternation of generation in which sporophyte is the dominant stage.

The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.

The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.

The gametes fertilize to produce a diploid zygote.

The zygote divides mitotically and matures into the diploid sporophyte.
