One example is that biotic humans drink water to survive and water is abiotic.
Answer:
The answer is A fungi
Explanation: Fungi are multicellular,with a cell wall, organelles including a nucleus, but no chloroplasts. They have no mechanisms for locomotion.
Answer:Recombination occurs through
crossing over and independent assortment. The correct option is B
Explanation:
-Genetic recombination is the process by which two different DNA are disintegrated and recombined to form new pairs of alleles. The process of recombination also involves the breakage and rejoining of parental chromosome. It occurs during meiosis ( that is formation of sperm and egg cells) and it gives them the correct number if chromosomes). Recombination occurs in meiosis through:
- CROSSING OVER: this is when paired chromosome press together and break, each may swap a portion of its genetic material.
- INDEPENDENT ASSORTMENT: which is the chromosome invented from either the father or mother can sort into any gamete and this produces a tremendous genetic variation. I hope this helps, thanks!
There is a physical barrier (small village in a mountain valley) that does not let those traits to escape the region. In other words, the physical barriers prevent gene flow occurring. This is what makes that specific gene for polydactylism to be prevalent in that area.
hope this helped.
The consequences of genetic drift are numerous. It leads to random changes in allele frequencies. Drift causes fixation of alleles through the loss of alleles or genotypes. Drift can lead to the fixation or loss of entire genotypes in clonal (asexual) organisms.
