The water molecule slows down, meaning that it freezes because When water vapor in the atmosphere cools down, it will condense and change back into liquid water, forming clouds.
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.
Answer:
True
Explanation:
Cholesterol is a lipid organic molecule which is the modified steroid form. The cholesterol is secreted by the animal cells as it a constituent of the animal cell membrane.
The cholesterol easily dissolves in the blood and is hydrophobic in nature so cholesterol is transported into the blood plasma in the form of lipoprotein complex.
There are four types of lipoproteins formed on the basis of their cholesterol density which are: VLDL, LDL, IDL and HDL.
HDL or high-density lipoprotein transports the cholesterol to the hepatic cells of Liver where the Liver enzymes convert the cholesterol to the bile acid and thus bile juice is excreted with bile.
Thus, True is the correct answer.
Answer:
The HIV genome is originally a RNA based genome.
Explanation:
Human immunodeficiency viruses are the one which infects human over time. The virus infects human body cells and progresses towards immune system failure which creates life threat for a patient. The disease is incurable till date but the effects can be slowed down by the medication and treatments. The disease in contagious and spreads by transfer of infected blood.
Answer:
the answer would be chromosomes.
Explanation:
A chromosome contains hundreds to thousands of genes.
