Which one of the following statements is not correct? A. Over a week-long period, if a healthy person were to ingest 35 g of NaC

baherus [9]

Answer:

The option D is incorrect.

Explanation:

It is not necessary that the substance needs to get filtered out of the glomerulus to be present within the urine. Some of the substances may be present in the urine due to the secretion in the renal tubules post the filtration process in the glomerulus.

Like in the proximal tubule of the nephron, secretion results in the transport of some of the molecules out of the blood and within the urine. These secreted substances can be hydrogen ions, potassium ions, creatinine ions, and some kinds of waste components like drugs.

The conduction of substances from peritubular capillaries to the renal tubular lumen is termed as tubular secretion, and the process generally takes place by passive diffusion and active transport.

White feathers in canaries are dominant to yellow feathers. A heterozygous canary is crossed with a homozygous recessive canary.

Lera25 [3.4K]

2:4 homozygous recessive; 50% heterozygous.

Explanation:

I will be using the letter B to represent dominant alleles and b to represent recessive alleles.

If a canary is heterozygous, that means that it will have (Bb). Hetero, means different, so it will never be both (BB) or (bb).

If the other canary is homozygous recessive, it will be (bb). Homo, means the same, so it will never be (Bb). If the canary were homozygous dominant, it would be (BB).

I made a Punnett square to figure out the ratio and the percentage that is being asked in the question. As you can see, if you bring down the alleles from both of the parents accordingly, you will get...

2:4 of the offspring will be potentially homozygous recessive.

50% of the offspring will be heterozygous.
