Answer: Meiosis produces the sex cells, that is the gametes (sperm cells and eggs) that unite to form a zygote. Meiosis ensures that the gametes have have haploid chromosomes so that the resulting zygote from their fusion will have diploid chromosomes.
Explanation: Meiosis is a type of cell division in which a cell divides twice to produce four daughter cells each with the half the number of chromosomes as the parent cell. Without meiosis new gametes are not produced. Meiosis ensures that the chromosomes are evenly distributed among the daughter cells and that each daughter cell contains 23 chromosomes. A sperm cell with 23 chromosomes fuses with an egg with 23 chromosomes to form a zygote with 46 chromosomes. If meiosis does not occur, gametes with haploid chromosomes will not be produced, and if the gametes have diploid chromosomes because meiosis does not occur, sexual reproduction will be a disaster because when two diploid gametes fuse the resulting zygote with be abnormal.
Answer:
B. Heating water
Explanation:
Molecular motion not not decrease but rather increase when heat is applied to water.
Answer:
Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. ... During the elongation stage, the ribosome continues to translate each codon in turn. Each corresponding amino acid is added to the growing chain and linked via a bond called a peptide bond.
Explanation:
Taking it
before exercise may stop the symptoms before they come. Albuterol is a bronchodilator that relaxes
muscles in the airways and increases air flow to the lungs. Albuterol inhalation is used to treat or
prevent bronchospasm in people with reversible obstructive airway disease. It
is also used to prevent exercise-induced bronchospasm.
