During the transcription, the DNA is used to produce proteins. But DNA is not directly transformed into protein
In order to do so, it must first copied to RNA to ensure the genetic information from the DNA doesn't become tainted

DNA is present within the nucleus of the cells and it is responsible for the production of various proteins and enzymes to keep the cellular activity going on. However, it cannot directly do so and seeks help of the messenger RNA molecules. DNA transcription is a process that involves transfer of the DNA code from the DNA to the mRNA molecule for the production of proteins.

Peripheral resistance depends on all of the following factors except __________.

pantera1 [17]

Options for the question have not been given. They are as follows:

blood vessel length

blood viscosity

blood vessel diameter

blood colloid osmotic pressure

Answer:

blood colloid osmotic pressure

Explanation:

Peripheral resistance is the resistance to blood flow by blood vessels.
It is directly proportional to blood vessel length as more the distance to travel, more will be the resistance.
It is also directly proportional to blood viscosity as more energy is required to push viscous material.
It is indirectly proportional to blood vessel diameter. More the diameter of the vessel, easier it is for the blood to pass.
However, it does not depend on blood colloid osmotic pressure. Colloid osmotic pressure is created by the protein components of blood and they do not have any direct impact on blood flow.

Exercising causing ___________

goldfiish [28.3K]

Answer:

c. increase HDL levels

Explanation:

Cholesterol is carried in blood in two ways, LDL and HDL. Both of them are lipoproteins made of fat and protein. LDL or Low Density Lipoprotein has 50% cholesterol and 25% protein by weight. HDL or High Density Lipoprotein has 20% cholesterol and 50 % protein. LDL carries cholesterol to arteries and deposits it there which is not good for the body. HDL on the other hand removes excess cholesterol from body via liver.

Aerobic exercise increases HDL values and lowers LDL values. It has been shown that exercising regularly can increase HDL level by 6% which is good for the overall health of the body. For maximum effect 30 minutes of moderate exercise should be done 5 times a week.

Describe an individual with the karyotypes shown?

Tems11 [23]

Answer:

Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions.

Explanation:

this is copied so be careful hope it helps

Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If two

PolarNik [594]

First, we consider the parents:

Phenotypes: Polka dots
Genotypes: Pp

Using a punnet square,

P p
P PP Pp

p Pp pp

Therefore, out of four, the phenotypes and genotypes of the offspring will be as follows:

Phenotypes: 3 with polka dots (75%) and 1 with solid (25%)
Genotypes: 1 dominant homozygous (25%), 1 recessive homozygous (25%) and two dominant heterozygous (50%)

The answer is option D.
