the endoplasmic reticulum
Explanation:
it is the endoplasmic reticulum and the ribosomes of the specialized cells in the pancreas that make insulin
The basic structure of bones is bone matrix, which makes up the underlying rigid framework of bones, composed of both compact bone and spongy bone. The bone matrix consists of tough protein fibers, mainly collagen, that become hard and rigid due to mineralization with calcium crystals.
In addition to loss of muscle mass, inadequate calorie intake can lead to loss of bone density and an increased risk of fatigue, illness, injuries and poor recovery.
<h3>Why is it important to consume adequate calories?</h3>
- When your consumption of calories is not adequate, your body will not get all the necessary nutrients.
- It slows down the metabolism so as to conserve energy
- Calorie restriction can lead to reduce in leptin, a hormone that regulates appetite.
- Lower levels of leptin can lead to increase in hunger thus a person overeats. This results in increase in body weight.
- Low-calorie dieting increases stress and results in the release of the stress hormone (cortisol).
- Due to response to stress, the body conserves energy and the metabolism slows to combat the risk of starvation.
- Therefore, it is important to consume appropriate amount of calories and nutrients.

Answer:
d. 1/3
Explanation:
Given, M is a dominant allele which is responsible for tailless kittens and m is recessive wild type allele which leads to kittens with tail. M is a lethal allele which means that if it is present in homozygous condition, the kitten will not survive. So the Manx cats should be heterozygous i.e. Mm.
When they mate, Mm X Mm :
M m
M MM Mm
m Mm mm
1/4 kittens will have MM genotype so they will not survive. Out of the remaining kittens, 1/3 will be mm and hence they will have normal tail. Remaining 2/3 will have Mm genotype like their parents and will be born without tail. Hence, there is 1/3 probability that one of the four kittens will have a normal tail.
