What are chromosomes?

Chromosomes are a threadlike interrelation of nucleic acids along with protein that is found in the nucleus of most/more of living cells and organisms that carries genetic info in the form of genes.

Chromosomes are what give us our characteristics. In the process of reproducing, the father's DNA will travel through the sperm to the eggs. These eggs, being in the mother, will have her DNA as well. Combining these DNA strands, it can make the hair color of a child, the eye color, ethnicity, and skin color.

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
