This happens early in embryonic development in females, where one of the two X-Chromosomes is randomly (and permanently) inactivated, as you said, in cells other than egg cells.
This phenomonon is actually called X-Inactivation.
X-Inactivation make sure that females, just like males, have a single functional copy of the X Chromosome in each and every one of their cells in their body.
Glad I could help, byee now
Answer:
The ear length will be 11 cm.
Explanation:
To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.
As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.
6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.
The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.
The Answer are :
Nervous Tissue
Immune System
Again, Immune System
Antibody
Antibodies
Vitamins
Vitamin C
osteomalacia
Chyme
glomerulus
Explanation:
Nervous tissue is one of four major classes of tissues. It is specialized tissue found in the central nervous system and the peripheral nervous system. It consists of neurons and supporting cells called neuroglia. The nervous system is responsible for the control of the body and the communication among its parts.
The immune system protects your child's body from outside invaders, such as bacteria, viruses, fungi, and toxins (chemicals produced by microbes). It is made up of different organs, cells, and The immune system protects the body from worms, germs, and other agents of harm. The immune system is like a medieval castle. ... The body's first line of defense consists of different types of barriers that keep most pathogens out of the body. Pathogens are disease-causing agents, such as bacteria and viruses. proteins that work together.
Honey has been linked to health benefits like improved heart health, wound healing, and blood antioxidant status. However, consuming too much may cause adverse effects due to its high sugar and calorie content. Thus, it's best to use honey to replace other forms of sugar and enjoy it in moderation.
Antibodies are proteins that recognize and bind parts of viruses to neutralize them. Antibodies are produced by our white blood cells and are a major part of the body's response to combating a viral infection. Antigens are substances that cause the body to produce antibodies, such as a viral protein.
Vitamins are substances that your body needs to grow and develop normally. There are 13 vitamins your body needs. They are. Vitamin A. B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B-6, vitamin B-12 and folate)
a disease caused by a deficiency of vitamin C, characterized by swollen bleeding gums and the opening of previously healed wounds, which particularly affected poorly nourished sailors until the end of the 18th century.
osteomalacia
Rickets is a rare disease that causes the bones to become soft and bend. African American infants and children are at higher risk of getting rickets. In adults, severe vitamin D deficiency leads to osteomalacia. Osteomalacia causes weak bones, bone pain, and muscle weakness.
Chyme or chymus is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum. Chyme results from the mechanical and chemical breakdown of a bolus and consists of partially digested food, water, hydrochloric acid, and various digestive enzymes.
The first step in making urine is to separate the liquid part of your blood (plasma), which contains all the dissolved solutes, from your blood cells. Each nephron in your kidneys has a microscopic filter, called a glomerulus that is constantly filtering your blood.
