A. The Sex.
This is because of the last pair int he Karyotype. which is used to determine the sex of a human (XX or XY). In this case because there are 2 long chromosomes, this is a female (XX), but if there was one long and one short, that would be a male (XY). This can also be seen if the chromosome types are labeled like in this diagram. <span />
Answer:
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs called alveoli in mammals and reptiles, but atria in birds. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration.
Explanation:
8. Genetic Code is <span>the nucleotide triplets of DNA and RNA molecules that carry genetic information in living cells, which is "language" for the genetic recipe book.</span>
9. No, the RNA has not undergone RNA processing yet. The AAC may be part of an intron--a non-coding sequence of RNA that is removed from the strand before exiting the nucleus and being translated into a protein.
