Answer:
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. ... A gamete will end up with 23 chromosomes after meiosis, but independent assortment means that each gamete will have 1 of many different combinations of chromosomes
Explanation:
Our living species migrated to the “environment”, established in the area, and then it will increase by number. After that we have competition and co-action resulting in the survival of fit individuals and the elimination of unfit individuals from the ecosystem.
Answer:
Option A, hydrophilic/hydrophobic forces
Explanation:
The cytoplasmic membrane consists of phospholipids which have both the hydrophilic and hydrophobic regions and hence are amphipathic in nature. Due to this structural complexity, phospholipids produces barrier both at the interior and exterior of cell and hence form a membrane bilayer under suitable conditions. For instance when it is in water, it arrange itself in a way that their hydrophobic tails lie at the inner side and hydrophilic heads face outer side.
Hence, option A is correct
Answer:B) homologous chromosomes trade pieces of dna
Explanation:
Crossing over occurs between two homologous chromosome of sisters chromatid. Crossing over leads to exchange of genetic material between the two sister chromatids leading to recombination.
