Compare and contrast DNA and RNA

1 answer:

6 0

Compare: both RNA and DNA have 3 nitrogenous bases: Adenine Cytosine and Guanine. Also both have a phosphate groups in their nucleotides

Contrast: RNA is a polymer with a ribose AND a phosphate backbone. It has four different nitrogenous bases: adenine, guanine, cytosine, and uracil.

DNA is a long polymer with deoxyriboses AND phosphate backbone. It also has four different nitrogenous bases: adenine, guanine, cytosine and thymine.

Hope this helps

Explanation:

Enzymes are identified to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Enzymes' specificity appears in their unusual three-dimensional structures. Like all enzymes, enzymes improve the reaction rate by decreasing its activation potential.

A sound wave with a frequency of 300 hertz is traveling through a medium at a speed of 320 meters/seconds. What is it’s waveleng

dalvyx [7]

1. The wavelength is the ratio of the wave's speed to its frequency in hertz or 1/s. This is shown below,
λ = s / f = (320 m/s) / (300 1/s) = 1.07 m
The wavelength is approximately 1.07 m.

2. The frequency is the ratio between speed and the wavelength,
f = (330 m/s) / 0.45 m = 733.33 hertz

Schach [20]

Answer:

D. All of these are correct.

Explanation:

Depending on the institution, substance-abuse treatments may vary in regard to duration and phases. Generally, treatments for substance abuse consist of four phases:

Initiation: This first stage focuses on providing helpful information to the person/patient about all treatments and options. During this phase, the person goes through a process of detoxification, that is, preventing them from using the drug to remove their dependence.
Abstinence - first phase: This stage is one of the most difficult ones as the person usually exhibits a variety of emotions associated with depression, sadness, anxiety because of the withdrawal of the drug. During this phase, they received psychological help to prevent any relapse and to become more stable, that is, to control drug cravings.
Abstinence - second phase: This stage is focused on maintaining abstinence and stability. In conjunction with the second phase, this is also difficult but rewarding. The person receives behavioral therapy so he/she can acknowledge how the drug intake resulted in numerous issues and, in contrast, stopping its use can change her/his life in a diversity of positive ways.
Aftercare: This stage focuses on long-term goals and, through therapy and counselling, helps the person to obtain education, find a job, and continue their stability and abstinence.
