Answer:

There will be 23 chromosomes in a sperm cell, 23 chromosomes in an egg cell, and 46 chromosomes in a white blood cell

Explanation:

Human cells are diploid in number i.e they exists in two basic sets (2N =46, where N is 23). So, cells of human body such as blood cells like white blood cells have two basic sets of chromosomes i.e 46 chromosomes, since they are produced by mitosis.

On the other hand, cells of humans involved in sexual reproduction such as the gametes (sperm and egg) have only one set of chromosomes since they are produced by meiosis - so they are haploid (N =23).

Answer:

Sperm=23

Egg cell=23

White blood cell=46

Explanation:

During cell division Meiosis produce haploid number of gametic chromosome 23.

The somatic cell contains 46 chromosome i.e diploid chromosome number. During cell division in meiosis gametes cells contains haploid number-23 chromosome which is half of the somatic cell chromosome.

During conjugation, haploid chromosome is donated by each parent to give a diploid organism with 46 chromosome number.

White blood cell contains 46 chromosome because it doesn't undergo cell division it is a somatic cell.

What happens to an enzyme when it performs its function? What does this mean about enzyme molecules??
ratelena [41]
1. Enzyme interacts with substrate
. 2. Enzyme may undergo a conformational change to capture the substrate ("induced fit" model)
3. Enzyme-substrate complex may undergo several changes to form the product(s).
4. The product(s) are released
. 5. The enzyme returns to its original form. It is then ready to do the cycle all over again.

If GFR is 125 ml/min, and you are studying a drug that has a renal clearance rate of 20 ml/min, you can conclude that
ahrayia [7]

Answer:

(B). The drug is reabsorbed.

Explanation:

Renal clearance rate determines the excretion of drugs into the urine during excretion. It is used to study the main process associated with a drug's renal excretion.

When the renal clearance rate is lower than GFR (glomerulus filtration rate), the drug is absorbed in the renal tubules. When the renal clearance rate is higher than GFR, the drug is secreted into the urine. When the renal clearance rate is equal to the GFR, the drug is neither reabsorbed nor secreted.

As for given drug, renal clearance is 20 ml/min (less than GFR), this drug will reabsorbed.

Thus, the correct answer is option (B).
