Answer:
<u><em>The correct option is C) Meiosis produces 4 daughter cells each with half the number of chromosomes of the original cell.</em></u>
Explanation:
There are two main processes by which cell divides:
1) Mitosis
2) Meiosis
All the cells of the body divide by the process of mitosis except the sex cells.<em> Sex cells divide by the process of meiosis.</em>
Meiosis can e described as a type of cell division in which four daughter cells are formed each having half the number of chromosomes as the parent cell. This is because the cell has to attain half of the maternal and half of the paternal chromosomes at the time of fertilization.
Crossing over and independent assortment are the phenomenon of meiosis which bring genetic diversity among parent and children.
Answer:
Hormones act as first messenger but not as second messengers.
Explanation:
Second messenger act as signaling molecule which are secreted in response to various biological signals generated by first messenger such as hormones,neurotransmitters etc.Second messengers include various bioactive molecules such as cyclic AMP(cAMP),cyclic GMP(cGMP),inositol triphosphate(IP3),diacylglycerol(DAG),calcium ions(Ca2+) etc.
Hormones are extracellular signaling molecules whereas second messengers are intracellular signaling molecules.
The answer is D.They reproduce independently. It is false because they need a host and can't survive by themselves.

In most cases, one uses tests whose size is equal to the significance level.
i would say by collecting data
