Answer:
'Cross experiments done by Morgan, illustrating the X-inheritance link of a mutation Thomas Hunt Morgan moved intensely in a program of breeding and crossing miles of fruit flies at New York University in a room that was renamed the Fourth of the Flies. He tried to mutate the flies with various means (X-rays, centrifuges, etc.) .The fruit fly which has 4 pairs of chromosomes. One of those pairs was identified as containing X and Y sex chromosomes. He applied Mendelian principles in flies. Morgan's inheritance study demonstrated inheritance linked to sex, and is one of the first evidences that confirm the chromosomal theory of cross-based inheritance. In 1909, Morgan detected a fruit fly (Drosophila melanogaster) with a strange mutation which he called "white eyes", due to the coloration of his eyes (contrary to normal, which is red). Analyzing this fly under the microscope Morgan discovered that it was a male, and could use it as a stallion so that he could observe how the new characteristic of white eyes would pass from generation to generation.All the offspring of this cross will have red eyes, which He made Morgan suspect that something strange had happened, since the color of the father's eyes could not have disappeared. He decided to take a couple of "daughters flies" and cross them together, just to see what happened. Morgan's surprise was very great, observing that among the "granddaughters" flies only males had white eyes. The problem then was to explain what had happened during the hereditary transmission for the color of the white eyes only the males possessed. .
Thanks to what we know about muscles and the fibers they contain, we can confirm that the statement in the question is in fact true.
Muscle is a type of tissue which due to coordinated systems that make up their composition, have the ability to contract. This ability allows for greater efficiency. In humans, the muscle systems are classified into three kinds:
- Cardiac muscle
- Skeletal muscle
- Smooth muscle
Despite the different classifications and functions of each muscle type, each of these muscles contains a combination of three types of muscle fibers, which are the fibers listed in the question:
- Slow oxidative
- Fast oxidative
- Fast glycolytic.

Answer:
Explanation:
B. Assessing the claims of your discussion partner
Answer: Addison disease is an adrenal insufficiency. This occurs because of the fact that adrenal gland produces very low quantity of hormones like cortisol, and aldosterone.
Explanation:
1. The symptoms of addison disease are loss of appetite, increased thirst, low mood, and muscle fatigue.
2. The addison disease is an autoimmune reaction, which can affect people of all age groups.
3. It can cause other diseases like tuberculosis.
4. The hormone replacement therapy is ideal for the treatment for addison disease. The use of oral corticosteroids is ideal. The diet containing balanced proteins, carbohydrates, fats, increased intake of vegetables including vitamins, and minerals are necessary for treatment of addison disease.
