Answer:
zinc oxide is a pure substance
The correct answer here is C. A molecule that has both polar and
nonpolar regions is called ampipathic. The polar end of the molecule is
water-loving, or hydrophilic, and the nonpolar end of the molecule will
be water-repelling, or hydrophobic. This means the molecules are able to
connect both to other water molecules, and to molecules of other
substances.
The answer is “there is genetic variation within the population”
The answer while be true because it's around the same rate.
Answer:
The answer is mother in meiosis II
Explanation:
nondisjunction can be defined as the failure of the segregation of the child chromosomes in meiosis I and meiosis II resulting in gametogenes. This results in abnormal gametes with some chromosomal imbalance being formed and subsequent fertilization of these gametes results in a generation of abnormal individuals.
According to exercise, red-green color blindness follows an X-linked recessive pattern and the phenotype is only expressed. the father cannot bring the possibility of color blindness to his children, and the nondisjunction, defined earlier, cannot occur in either meiosis I or meiosis II. As a conclusion we can say that it may have a place in meiosis I or meiosis II corresponding to the mother and although the mother's condition may be normal, the first child would be compromised with color blindness, therefore, the mother is the carrier.
