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.

Scientists have conducted multiple experiments on cancer cells to determine how they reproduce. All studies have shown the same
Sonbull [250]

Cancer cells reproduce the same way the other cells reproduce. The difference between cancer cells and others is that their reproduction is uncontrollable. They constantly go through the cell cycle and they reproduce. Two ways cell reproductions are meiosis and mitosis. DNA duplicates itself. Cancer is incessantly receiving messages.

Basic body color for horses is influenced by several genes, one of which has several different alleles. Two of these alleles— th
Phantasy [73]

Answer:

<h2>No,</h2><h2>Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute</h2>

Explanation:

 As given:

The chestnut (dark brown) allele and a diluting (pale cream) alleles show incomplete dominance, means that both the alleles in heterozygous condition show their effect. So the heterozygous show the phenotype which is intermediate of both the parents, here a horse heterozygous for these two alleles is a palomino.

 There is in fact, no particular allele present for palomino, this phenotype only results due  to having two  different alleles for a gene. So, palominos can never be pure-breeding because they can never be  homozygous.

Let P1 chestnut and P2  dilute,

Palomino is P1P2

The Punnett’s  Square for palomino mated to palomino:

P1P2×  P1P2

Gametes are: parent-1 P1 and  P2 , parent-2:  P 1  and P2

Progeny are:  P1P1,      P1P 2,    P 2 P1,    P2 P2

Genotypic Ratio: 1 P1P 1  : 2 P1P 2  : 1 P2P 2

Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute
