The failure of chromosomes to separate during meiosis is called

Nondisjunction.

Explanation:

Nondisjunction occurs when chromosomes fail to segregate during cell division. It can occur during the process of mitosis as well as meiosis.

The cells in the body are all diploid, that is, have two sets of 23 chromosomes except the gametes or sex cells which are the egg and sperm cells which have only one set of 23 chromosomes also called haploid.

Meiosis occur when haploid gametes are created from a diploid cell. In meiosis, chromosomes separate to produce four gametes, all haploid.

The failure of these chromosomes to separate normally, is called nondisjunction.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
