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

Answer 1
Answer:

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.

A biology student is studying ways to grow crops in soils that are high in salts and other dissolved solids. To determine whether corn plants can tolerate salty soil conditions, she grows one corn plant in typical non salty soil and one corn plant in the same soil plus 0.5 kilograms of salt. after 6 weeks of growth, the corn plant grown in salty soil is only about 50% of the mass and height of the corn plant grown in non-salty soil. How can this research be improved so that she will have greater confidence in her data?

A student did an experiment with two identical plants, Plant 1 and Plant 2. About 10 mL fertilizer was added to Plant 1. About 200 mL of water was added to each plant every day. The height of the plants was recorded over a period of 5 weeks in the table shown below.Week Height of Plant 1 (in inches) Height of Plant 2 (in inches)

Fertilizer helps plants grow taller. Fertilizer can help a plant survive for five days. Plants need more than 10 mL fertilizer to grow in size.
I choose A is it right?

Answers

Answer:

Answer A is correct

Explanation:

This is an experiment in which both plants were with the same conditions of water and sun during the whole experiment, so the dependent variable that you want to test is the heigh, that is why is the main difference in both plants, and the independent variable is the fertilizer, is the one that you observe in your results.
A would be correct because the other answers make no sense since they both grew.

The scientist who first studied the world of microscopic life was A. Copernicus.
B. Kepler.
C. Leeuwenhoek.
D. Bacon.

Answers

I believe the answer is C, Leeunwenhoek because Copernicus was an astronomer, Kepler was a mathematician and astronomer and I THINK Bacon was a philosopher. Out of the 4, Leeuwenhoek was the only one strictly known for being a microbiologist, not only that but he was the first. I hope this helped :)

A stem has nodes and internodes. Which of the following features helps identify nodes on a stem?the presence of buds on the nodes

the origin of roots from nodes

the swollen appearance of nodes

Answers

The answer is the presence of buds on the nodes.

Node is a segment of the stem where buds are attached. A segment between two nodes is known as internode. Node is not swollen, and more important, there are no nodes on the roots, nor the origin of roots is from nodes. Nodes are easily identified thanks to buds attached to them.
