Answer: Mycorrhiza
Explanation: Mycorrhiza is a symbiotic relationship between a plant and a fungi. Nearly 80 percent of all plants with root systems participate in this mutualistic relationship. In mycorrhiza, the fungus forms a haustoria that penetrates the cell walls of the plant's roots. The fungus absorbs all the nutrients from the roots as they are transported to the plant. In return, the fungus gives the plant necessary chemicals and minerals that it cannot properly reach on its own.
Answer:
- Populations must be very large -True
- The frequency of all genotypes must be equal. False
- Gene flow from other populations must be zero. True
- Matings must be random. True
- There should be no natural selection. True
Explanation:
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- <u>Random matings</u>: mating probabilities between individuals with determined genotypes depends on the products of frequencies of those genotypes.
- No superposed generations: each individual can leave their gametes in the pool only once.
- No mutations: There is no incorporation into the genetic pool of new gametes originated by mutation of preexistent alleles.
- <u>No migration</u>: There is no incorporation of gametes originated in another population.
- <u>Infinite population size</u>: the probabilities of randomly taking an A gamete from the pool are p and the probabilities of taking a B gamete from the pool are q.
- <u>No natural selection</u>: Each individual has the same surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.
Hi there,
Cytokinesis is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells.
This is how it occurs:
Animal cells: divide by a cleavage furrow
Plant Cells: divide by a cell plate that eventually becomes the cell wall.
Hope this helped :)
Have a great day
