Answer:
The genes that the child inherited from the parents is the SS gene
Explanation:
The genetic composition of the haemoglobin genotype is given by two gene variants; A which is dominant and S which is recessive. As such, an individual can be AA, AS or SS. Individuals that are AA and AS do not show traits of the disease, but SS individuals have sickle cell anaemia.
From this example, since both parents have no symptoms and their child have sickle cell, their genotypes most likely were AS and AS. Let me show you how:
A S
A AA AS
S AS SS
From the cross above, there is a 1 in 4 chance that if both parents were AS, their child will be SS. Any other composition from the parents will not produce an SS offspring. Hence the genes that the child inherited from the parents is the SS gene.
double stranded molecule does not describe the structure of RNA. Most RNA are single stranded with partial double stranded regions. RNA has basic component as the DNA that is have four nitrogenous base, contain phosphate group and have 5 carbon sugar.
Answer:
The main reason for exhalation is to rid the body of carbon dioxide, which is the waste product of gas exchange in humans. Air is brought in the body through inhalation. During this process air is taken in through the lungs.
Ghrelin is a hunger-stimulating hormone which is secreted by specialized cells in the stomach.
Ghrelin is a hormone made in the intestine. It is often called the "hunger hormone" and is sometimes called lenomorelin.
It reaches the brain through the bloodstream and tells the brain to feel hungry and start looking for food.
It's main function is to increase appetite. Eat more food, take in more calories and store fat.
In addition, it affects the sleep-wake cycle, reward-seeking behavior, taste sensation, and carbohydrate metabolism.
This hormone is made in the stomach and is secreted when the stomach is empty. It enters the bloodstream and affects a part of the brain called the hypothalamus, helping regulate hormones and appetite. Lower levels make you feel fuller and easier to cut calories.
