3 is parasitism, 2 is mutualism, and 1 is commensalism.
Aneli [31]3 years ago
3 0

The right matches are:

1. is Mutualism

2. is Commensalism

3. is Parasitism

Mutualism is an interaction between two species, in which both organizations benefit from this relationship. This is called a mutual benefit interaction. However, mutualism in the strict sense is not a binding relationship between the individuals involved.

Commensalism is a type of natural and frequent or systematic biological interaction between two living beings in which the host provides some of his own food to the commensal.

Parasitism is a biological relationship between two living beings where one of the protagonists (the parasite) takes advantage of a host organism to feed, shelter or reproduce.

Verizon [17]

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>

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.
