The answer is both in males and females; only in males. Males
have one Y chromosome and one X chromosome, while females
have two X chromosomes. In mammals, the Y chromosome controls a
gene which is the SRY, which produces embryonic improvement as a male. The Y chromosomes of males and
other mammals also contain other genes needed for normal sperm production.

<span>Q1. The answer is A.Biological information in a cell passes from DNAto RNA to proteins. The biological information is the part of DNA. During transcription, DNA is transcribed into RNA which now serves as a template for the synthesis of proteins. Thus, the central dogma of molecular biology describes how biological information in a cell passes from DNA to RNA to proteins.
Q2. The answer is D. 46. In a human diploid somatic cell (2n), there are 23 chromosomes present in two copies - 22 pairs of autosomes and 1 pair of sex chromosomes. So, in a normal human karyotype there will be in total 46 chromosomes (23 pairs in 2 copies: 23 × 2 = 46).
Q3. The answer is A. inbreeding. Inbreeding is a breed from closely related organisms. Inbreeding causes a decrease of genetic variation by increasing homozygosity. This way, it can cause the genetic defect by bringing two recessive alleles together.</span>

Explanation:
Answer:
The procedure you would follow to identify the three solutions A, B and C by Benedict’s test;
- a brick-red precipitate will be seen, with the glucose solution that is a positive result, separate remaining solutions in boiling water to a high temperature until enzyme will be denatured.
- Mix these heated solution samples with the sample of the other solution;
Allow the solution to react and then carry out Benedict’s test on the two tubes; one will produce the positive result for the benedict test due to the presence of maltose sugar.
