If the somatic cells of a human contain 46 chromosomes, then after meiosis new sex cells would contain chromosomes.

23 chromosomes.

Explanation:

Meiosis is a process where a cell divides twice to produce four sex cells containing half the original amount of genetic information. These sex cells are known as gametes, which are sperm in males, and eggs in females.

These gametes are created between the first time the cell divides, called meiosis I, and the second time it divides, known as meiosis II.

Meiosis I separates homologous chromosomes producing two haploid daughter cells cells, which have 23 chromosomes each. Because of this, the ploidy is reduced from diploid to haploid, and meiosis I is referred to as a reductional division. During Meiosis II, sister chromatids are separated, creating four haploid daughter cells.

answer: although many types of viruses can cause a common cold, rhinoviruses are the most common culprit. a cold virus enters your body through your mouth, eyes or nose. the virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks. theres your answer

explanation:

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
