Answer:
The correct answer is option - A. Gametophyte, C. spore, and D. sperm.
Explanation:
The egg cell of a plant is haploid in the cell which means it has only one set of chromosomes. The haploid cells arise from the meiosis cell division in parent sex cells. These parent cells are divided into four cells with half of the chromosome number in comparison to the parent cells.
The gametophyte, spore, and sperm all three are the product of the meiosis division and are haploid in number.
Thus, the correct answer is option - A, gametophyte, C. spore and D. sperm.

Answer:
<u>Endocrine system, minutes to days</u>
<u>nervous system, less than one second</u>
Explanation:
Nervous system takes information through senses, processes the information and triggers reactions.
Nervous system has less reaction time because it uses <u>electrical signalling </u>(neural impulses) while Endocrine system uses<u> chemical signalling </u>(hormones).
The endocrine system responds to stimulus by secreting hormones in the blood (circulatory system) that travels to the target organ, and hence take more reaction time.
Answer:
DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect.

Answer:
<h2>Facilitated diffusion
.</h2>
Explanation:
1. Diffusion: it is the net passive movement of particles from higher concentration to lower concentration. Diffusion continues until the concentration of substances is equal through out.
2. Facilitated diffusion: is the process of passive transport of molecules or ions across a biological membrane and requires (via) a specific carrier protein.
3. Facilitated diffusion is passive type and require specific protein and it requires no energy from the cell.
4. It requires specific proteins through which molecules move from one side to another.
