Answer:
Towards the southern of the sound
Explanation:
As the motion of the source of sound is moving,the percieved sound frequency varies .this is known as Doppler effect.the sound waves emited by the sources tends to bunch up in front of the source and spread out behind the source.
Since the falcon is moving towards the sound,the frequency increases and so does the pitch of the sound
in the muscles.

Answer:
The functional unit of a muscle cell is known as a "sarcomere" which covers the distance between the two Z-lines.
The sarcomere consists of A-zone which contains both thick and thin filaments, H-zone which contains only thick filaments and I band which contains only thin filaments.
During muscle contraction, thick and thin myofibrils slide over each other due to which the distance between two z-line get reduced.The H and I zone gets shortened but A zone does not shorten but come close to other A- bands and disappears.

3-only one type of cell involved
4-requires two parents
Answers
It requires two parents, does not describe parthenogenesis in organisms.
The correct option is 4.
What is parthenogenesis?
Parthenogenesis is the process in which reproduction happens without the fertilization of sperm.
It is the development of an embryo without fertilization of the egg.
Animals such as bees, wasps, and ants, do parthenogenesis.
It includes only one parent.
Thus, the correct option is 4, which requires two parents.

Answer:
Probability that at least one of them will be affected = 3/16 + 3/16 + 1/16 = 7/16
Explanation:
If both parents are heterozygous for a genetic disease; Xx and Xx
The offspring's they will produce will be as follows ; XX, Xx, xX, xx
- Probability that first child will be affected = 1/4
- Probability that first child will not be affected = 1 - 1/4 = 3/4
- Probability that first child have it and second does not = 1/4 x 3/4 = 3/16
- Probability that first child does not have it, second child have it = 3/4 x 1/4 = 3/16
- Probability that both of them will have it = 1/4 x 1/4 = 1/16
- Hence, Probability that at least one of them will be affected = 3/16 + 3/16 + 1/16 = 7/16
