I believe the answer should be mitosis.
Mitosis is a kind of cell division that produces 2 daughter cells that are genetically identical to both the other daughter cell and the parent cell. It is a process of exact duplication of the genetic material (chromosomes) in the parent cell, then dividing, each with the same original number and sequence of chromosome.
It is used for growth and development because they're the process of where the number of cells increases, and how? By mitosis. These new cells must be exactly identical to the other originally existing cells, as for example you wouldn't suddenly grow some skin cells as a replacement of nerve cells. Mitosis of nerve cells produces the same type of nerve cells, mitosis of skin cells produces skin cells.
Therefore, your answer should be mitosis.
Answer:
a,c,d
Explanation:
Crossing over occcur when genetic material is exchanged between homologous chromosome this leads to formation of new genes that creates diversity.
homologous chromosome assort imdependently i.e seperate from each other leading to the formation of an entirely new gene that creates diversity.
Genetic recombination when gene recombines together to produce a unique type. It occurs between different species.
The most constant temperature is found in tropical rainforest.
Tropical rainforests are found near the equator and have temperatures between 20°C and 25°C year-round. There is no dry season in tropical rainforests, all months have an average precipitation and receive about 250 cm of rainfall per year. Tropical forests are classified by the amount of rainfall received each year.
Answer: Option A ,Band C.
Explanation:
Sympatric speciation is the evolution or isolation of new species from the original populations of species occupying in the same geographical area. Sympatric speciation commonly occur due to sexual selection of mates can cause reproductive barriers or isolation which keep gene pools separate. A plant with extra set of homologous chromosomes is an example of sympatric speciation.
