Answer:
D
Explanation:
This involves a dihybrid inheritance I.e. two genes are being passed on. During meiosis, specifically, the Prophase stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) line side by side. According to the question, one chromosome contains A and B alleles and its homologue, received by the other parent carries a and b alleles. This means that the diploid individual has a genotype AaBb for that gene.
According to Mendel's law of independent assortment, the alleles separate independently of one another into gametes. I.e. allele A and a separates into the gametes without affecting alleles B and b of the other gene.
Crossing-over, which is the exchange of chromosomal segment occurs between the two homologues. Hence, the exchange of chromosomal segments containing alleles in the individual will possibly produce four gametes with the genotypes: AB, Ab, aB, ab.
Organ system is the answer
Answer:
The volume of solution B will increase
Explanation:
In a non-penetrating solute, there is denial of a solute to cross the cell membrane.This implies that the solute will not be able to cross the cell membrane. So if the biological membrane is serving as a partition between a solution A containing 400 mosmol/L non-penetrating solute and a solution B containing 600 mosmol/L non-penetrating solute, The volume of solution B will increase.
Your answer is D. Mustard Seeds. They grow in the the Middle East.
There are 4 electrons altogether shared between carbon atoms in a molecule of C2H4, to be more precise there are 2 electron pairs shared between the carbon atoms.
