B. a cyanide compound
C. defensins
D. nitric oxide
Option (D.) Nitric oxide is not a component of saliva.
Thus Option D. nitric oxide can't be present in saliva as all the other component are present in human saliva.

a. It was inspired in part by patterns observed in the fossil record.
b. It suggests that subgroups diverge and evolve at about equal and constant rates.
c. It suggests that most species undergo little phenotypic change during most of their evolutionary duration.
d. It proposes that most evolutionary change is concentrated in relatively brief episodes of change.
e. It appears to be well supported by the fossil record.
The following is not true of the punctuated equilibrium theory is ‘It suggests that subgroups diverge and evolve at about equal and constant rates.’ The answer is letter B. the statements ‘It was inspired in part by patterns observed in the fossil record’, ‘It suggests that most species undergo little phenotypic change during most of their evolutionary duration’, ‘It proposes that most evolutionary change is concentrated in relatively brief episodes of change’ and ‘It appears to be well supported by the fossil record’ best supports the punctuated equilibrium theory.
Answer:
Gregor Mendel was the first biologist who applied the principles of mathematics to study the pattern of inheritance in Biology. This led to the criticism and not an acceptance of his work at his time but after his death, his work was widely recognised as:
1. Mendel's work provided each and every detail of the experiment from species to a number of offsprings and traits.
2. His experiments included a large sample size which reduced the chances of error in his results.
3. He studied the pattern of inheritance for distinguishing traits.
4. His ideas and explanation on experiments were logical which were supported by the scientists later.
These logical ideas later helped recognize his work and he became the Father of Genetics.

Answer:
a. all tall plants
Explanation:

(B) Species thought to be related through evolution from a common ancestor show many anatomical similarities.
(C) The stages of embryological development in animals are quite similar among highly diverse types of organisms.
(D) Similarities in chromosome structure, DNA sequence, and amino acid sequence suggest relationships among organisms descending through evolution from a common ancestor.
(E) The most well adapted individuals do not always produce the most fit offspring.
