Which of the following is a viral infection that most adults contract 2 to 4 times a year?

Nucleosides are polymers that have just a base and a .

ra1l [238]

Answer:

Chemically altered nucleosides derived from canonical ribo-or deoxyribonucleoside-derivatives of adenosine, cytosine, guanosine, and uridine or thymidine are found in all types of nucleic acids, DNA and RNA. They are particularly abundant in noncoding RNAs, such as transfer RNAs and ribosomal RNA of higher organisms. By increasing the structural diversity of nucleic acids, modified nucleosides play important roles in gene expression and in regulating many aspects of RNA functions. They also contribute to nucleic acid stability and to protection of genetic materials against virus aggression. In this chapter we present a historical overview of the discovery, occurrence, and diversity of the many naturally occurring modified nucleosides that are present in both DNA and RNA of diverse organisms. We also briefly describe the different enzymes that accomplish these nucleic acid ‘decorations’. More information about the structure, function, biosynthesis and evolutionary aspects of selected modified nucleosides in DNA and RNA and their corresponding modification enzymes can be found elsewhere in this volume.

Professor Black explains that genetics, diet, lifestyle, activity, and exposure to pollutants all play a role in the aging proce

adell [148]

Answer: The Generalised Slowing Hypothesis Theory

Explanation:

The Generalised Slowing Hypothesis is built upon wide observations in many studies of age related slowing and suggests that it is the primary contributor to the declines in cognitive functioning seen with aging.

As people age, B lymphocytes and T lymphocytes become less active. These cells secrete antibodies and are thus crucial to the immune system. T cells are made in the thymus which shrinks as aging occurs. Thus reducing the body's ability to fight infections as aging occurs.

Through the normal aging process, DNA is damaged by environmental factors such as pollutants and toxic agents. As a result, there is deletions of genetic material and mutations in DNA replicated in new cells. Reduced functioning in cells and tissues occur when these errors accumulate.

Also as aging occurs, glucose molecules attach themselves to proteins and form cross links. These crosslinks reduce the flexibility of tissues making them become stiff. The circulatory systems becomes less efficient since the tissues of the lungs, heart and arteries lose flexibility.

How could a conditioning program, focused on muscular endurance, impact body composition? Question 5 options:

Ksju [112]

Answer:

The answer is no impact on the body fat percentage.

Explanation:

It would have no impact on body fat percentage as the conditioning would not be trying to target that area.

In which type of treatment does the patient follow verbal prompts to envision a specific?

Jlenok [28]

a form of therapy called guided imagery in which a patient is given vocal instructions to vividly picture a particular, serene setting while separating themselves from any discomfort or stress they are currently going through.

<h3>The guided imagery technique is what?</h3>

In guided imagery, a stress-reduction technique, you use your imagination to conjure up images of people, settings, or moments that make you feel calm, at ease, and joyful. In that it makes use of all of your senses, imagery differs slightly from other stress-reduction methods.

<h3>What sort of guided imagery is that?</h3>

In guided imagery, your entire body is used. Imagine the warm air on your skin, the clear, blue ocean, the sound of the waves, the pleasant aroma of tropical flowers, and the taste of coconut to create the impression that you are there, for instance, if you desire a tropical atmosphere.
