Which of the following is the main benefit of ozone? A. reduces pollution levels B. absorbs ultraviolet radiation from the Sun C. filters particulates from the atmosphere D. neutralizes the effects of carbon monoxide Please select the best answer from the choices provided. A B C D

Answers

The main benefit of ozone is that it absorbs ultravioletradiation from the Sun. The correct option is B.

The Earth's atmosphere contains ozone (O3), which is essential for absorbing solar ultraviolet (UV) radiation.

Only a small fraction of UVArays are allowed to reach the Earth's surface because of the protective shielding effect of the ozone layer, which is found in the stratosphere.

Ozone helps shield living things from the negative consequences of excessive UV exposure, which include skin damage, eye issues, and a higher risk of skincancer, by absorbing UV radiation.

Increased UV radiation levels that reach the Earth's surface as a result of the ozone layer being depleted, as seen in some areas (like the ozone hole above Antarctica), pose serious threats to human health and the environment.

Thus, the correct option is B.

Toxic waste spills are a direct source of water pollution.
a. True
b. False

Answers

There are twotypes of sources of water pollution; the direct sources and indirect sources. Directsources include effluent streams from factories, refineries, was treatment plantsand others. Whereas for indirect sources, includes contaminants that enter the watersupply from soil or groundwater systems and from the atmosphere via rain. Most ofthese sources derive from human activities. Toxic waste spills are by-productsfrom the industrial plants or factories. It is a direct source of waterpollution. The answer is true.
Toxic waste spills are a direct source of water pollution.

Which is TRUE of only children relative to children with siblings? a. They are more egotistical. b. They are more selfish. c. They are smarter and more mature. d. They are more likely to be ""spoiled brats.""

Answers

Answer: Option B) They are more egotistical

Explanation:

A singly raised child is more likely to be egotistical i.e considering himself or herself to be better and more important than others.

This perception is simply due to the focused attention, endowment, care and nurture given to such a child (in the absence of any sibling) by the parents.

Thus, singly raised children are more egotistical than children with siblings

Some proteins on the surface of a mammalian cell contain carbohydrates. These proteins are synthesized by _______ and the sugars are added in the _______.a) cytoplasmic ribosomes; smooth endoplasmic reticulum

b) the Golgi apparatus; rough endoplasmic reticulum

c) ribosomes on the rough endoplasmic reticulum; Golgi apparatus

d) mitochondrial ribosomes; smooth endoplasmic reticulum

e) cytoplasmic ribosomes; plasma membrane

Answers

Answer:

c) Ribosomes on the rough endoplasmic reticulum; Golgi apparatus

Explanation:

Endoplasmic reticulum, a member of endomembrane system. If it contains ribosomes on their surface, they are called Rough Endoplasmic Reticulum (RER). RER is the site for protein synthesis.

Newly formed protein undergoes modification, one such modification is the addition of carbohydrate side chains to form glycoprotein. The protein then moves to the Golgi for modification.    

What is the hardy weinberg principle and why is it important

Answers

Also known as hardy-Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. Because one or more of these influences are typically present in real populations, the hardy-Weinberg principle describes an ideal condition against which the effects of these influences can be analyzed.

It is important for systems where there are large numbers of alleles that can determine the result of genotype counts. And series of test will be applied: Pearson's chi-squared test, Fischer's exact test, and MCMC method.
