3 Only b, d
4 a, b, d
Explanation:
b
RNA = unstable, rate of mutation high
DNA = more stable, rate of mutation low

According to Hardy-Weinberg’s law, if the homozygous recessive allele frequency of given species in a population, is 16%, then find out the frequency of dominant allele. Also calculate the percentage of heterozygous individuals in the population.
1 Frequency of dominant allele 0.4, % of heterozygous individuals 16%
2 Frequency of dominant allele 0.4, % of heterozygous individuals 60%
3 Frequency of dominant allele 0.6, % of heterozygous individuals 60%
4 Frequency of dominant allele 0.6, % of heterozygous individuals 48%
Explanation:
d
Given frequency are recessive allele that is 16%.

What was the most significant trend in the evolution of modern man (Homo sapiens) from his ancestors:
1 Shortening of jaws
2 Binocular vision
3 Increasing cranial capacity
4 Upright posture
Explanation:
c
About 15 mya, primates called Dryopithecus and Ramapithecus were existing. Ramapithecus was more man-like while Dryopithecus was more apelike.Homo habilis.The brain capacities were between 650-800cc. They probably did not eat meat. Fossils discovered in Java in 1891 revealed the next stage, i.e., Homo erectus about 1.5 mya. Homo erectus had a large brain around 900cc. From ancestral human to modern man and then man of today cranial capacity are gradually increased hence it is most important trend in the
evolution of man.
