<span>The movement of ions, glucose and amino acids, group the group of molecules necessary for the active transport that is the transport that occurs when there is the circulation of molecules. The solutes are routinely produced which are ions and other smaller molecules and lipid bilayers that have proteins and circulate through the plasma membrane.</span>

What male reproductive structure releases sperm into the vas deferens?

lisov135 [29]

The answer is epididymis.

<span>Testicles contain seminiferous tubules, in which sperm is produced, and an epididymis, in which sperm matures. Mature sperm passes through the epididymis to the vas deferens. There, it combines with a liquid secretion from the seminal vesicles and continues through the prostate gland to the urethra. Sperm containing fluid is called semen and it is ejected through the urethra.</span>

Glucose travels in the plasma or liquid part of

djverab [1.8K]

Answer:

Explanation:

Glucose is a sugar, highly soluble in water because it has lots of polar hydroxyl groups (-OH) which can form hydrogen-bonds with water molecules. These types of bonds are intermolecular forces which are present in other macromolecules like the DNA or proteins.

Cholesterol and triglycerids are lipids. These have long chains of hydrocarbons, which are non polar and therefore insoluble in water.

Blood is made of a solid and a liquid part. <u>The solid part contains cells</u>. <u>The liquid part (plasma), is made of water, salts, and proteins</u>. Glucose and cholesterol/triglycerids travel in the liquid part of the blood, in an aqueous environment. Because the lipids are not soluble, they need to travel with a carrier protein that keeps them protected from the surrounding water.

In numerous studies, treatment of prion preparations with ionizing and UV radiation does not reduce transmission of disease; how

mel-nik [20]

Answer:

A. Prions do not contain genetic information, which is affected by ionizing radiation.

B. Denaturants may affect the tertiary structure of prions.

C. Prions are proteins.

Explanation:

Prions are the proteinaceous infectious particles that cause many degenerative diseases of neurons in both animals and humans. They consist of only protein and no DNA or RNA. Due to the absence of DNA or RNA as genetic material, these infectious particles are resistant to ionizing radiation. Ionizing radiations affect nucleic acids of pathogens to destroy them.

Denaturation of proteins affects their secondary and tertiary structures and leave them non-functional. Denaturation may be caused by changes in temperature, pH, disturbance of hydrogen bonds, etc. Therefore, to destroy prions, they need to be denatured.
