Answer:
O Vestigial organs show that whales may have evolved from a common ancestor shared with land-dwelling animals
Explanation:
Vestigial organs are defined as the organs which are no longer beneficial for survival.
Whales can be observed with tiny, unused hip and pelvis bones which are vestigial organs for them as they are no longer beneficial for their survival. The vestigial organs are the evidence of evolution in organisms and in whales also these vestigial organs says that whales and land-dwelling animals may have common ancestors. Later on with evolution some land-dwelling animals might move to water systems and hip and pelvis bones become vestigial organs for them which along with time decreasing in the future offspring.
Hence, the correct answer is "Vestigial organs show that whales may have evolved from a common ancestor shared with land-dwelling animals".
Answer:
The variable b represents the growth or decay factor. If b > 1 the function represents exponential growth. If 0 < b < 1 the function represents exponential decay. When given a percentage of growth or decay, determined the growth/decay factor by adding or subtracting the percent, as a decimal, from 1.

Virulence factors of virus aids in its ability to infect cells.
Explanation:
Virulence factors help pathogenic microbes to infect host cells by virulence mechanisms – invade host, cause and spread disease, evade the defense or immune mechanism of the host. These factors makes the virus to grow, replicate, and modify the host cells due to its toxicity.
Viruses binds to the receptor protein of the host cell.
Different types of virulent factors are: invasion factors, adhesive or adherent factors, capsules, endo and exotoxins, etc.
The virulence factors decides the severity and rate of spread of an infection
