Three ways you can identify pairs of homologous chromosomes?

Biology

diamong [38]3 years ago

An organism inherits one chromosome of a homologous pair from the maternal parent and the other chromosome from the paternal parent. Although both chromosomes possess the same genes and loci, they may feature different alleles, or versions, of those genes. For example, a maternally inherited chromosome in a pea plant may contain an allele that codes for a green pod, while the allele for a yellow pod may be found at the same location on the paternally inherited homologous chromosome. The differences between alleles of a gene are determined by deviations in their DNA sequences.

A diploid organism possesses two copies of each type of chromosome, with the potential exception of the sex chromosomes, in each of its cells. Humans, for example, have a total of 46 chromosomes in their cells. Human females have two copies of the sex chromosome called the X chromosome, so they have 23 sets of homologous chromosomes. Human males, however, possess one X sex chromosome and one Y sex chromosome, so they have 22 sets of homologous chromosomes, plus two sex chromosomes that are not homologous.

My homework says chicken has more protein carrots, what dors that mean?
nataly862011 [7]
Meats, beans and other foods like this are considered protein foods. It means that the chicken has amino acids that your body needs to survive. That's why it can be harder for vegans to find things to eat. Carrots may be healthy for you but they don't contain the amino acids that your body needs.

Explanation:

Adrenocorticotropic hormone is a hormone from the anterior pituitary whose function is to stimulate the adrenal cortex (fasciculate and reticular areas); In other words, its biological function is to stimulate the secretion of cortisol. The ACTH test is used as an indicator of pituitary function and is useful in the differential diagnosis of: Addison's disease,Congenital adrenal hyperplasia,Cushing's syndrome.ACTH secretion is pulsatile and shows a diurnal variation in plasma concentrations, being maximum at approximately 8:00 am and minimum at midnight. ACTH secretion increases with stress.

Difference in powdered salt and granulated salt​
In-s [12.5K]
Rock salt is also known as halite. It is different to sea salt because it is already found in a solid form and then mined. Table salt (refined salt) can also be produced from solid salt which is found underground and then refined to remove any impurities.

kati45 [8]

Answer:

Excess glucose is stored as muscle glycogen, reducing the amount of lactate generated in muscle during the event.

Explanation:

Carbohydrates are a main source of energy for the body and loading up on carbohydrates is believed to help store large amountsof energy and is used to help replenish and load muscle glycogen content. Athletes tend to load a few days prior to a long endurance athletic event to help provide adequate and extra energy to muscles.
