Which gas is most effective in absorbing incoming harmful ultraviolet radiation in the earth's stratosphere before that radiatio

n reaches earth's surface?

Answer:

Ozone (O₃) gas

Explanation:

In the Earth's stratosphere, oxygen gas (O₂) is combined with atomic oxygen (O) to form ozone gas (O₃). This is very important because ozone protects the life on Earth from ultraviolet (UV) radiation from the Sun. UV radiation is high-energy radiation, and it is very dangerous for living organisms. Ozone molecule (O₃) absorbs UV radiation and it breaks down by forming O₂ and atomic oxygen (O) again. In this way, it protects the Earth from nocive radiation.

<h2>Capillary Smooth Muscle Contraction</h2>

Explanation:

  • Blood flows through blood vessels, which form the closed system called the circulatory system. Like a system of roads, the circulatory system has its highways, back roads, and alleyways, which we call arteries, veins, and capillaries
  • Capillaries are the alleyways that extend and branch into every tissue of your body, ensuring that every cell has a blood supply. It is here, in the capillary beds, that your cells pick up oxygen and nutrients and drop off carbon dioxide and wastes
  • Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events
  • All muscles contract as a result of interaction between special proteins within the myocytes. Skeletal, cardiac, and smooth muscle cells synthesize the contractile proteins actin and myosin, which are needed for muscular contraction

Which of the following human activities would be most beneficial to soil conservation?
kifflom [539]
The best answer is D because construction would be bad for the environment and take up space on the soil that is trying to be preserved. Also, for C, planting only one crop type in soil is not very beneficial to the soil at all. IT is best to plant multiple crops in the soil and move the crops to different parts of the soil each year when planting them.

Does a mom or dad ever give more DNA to a baby than the other parent? Why?​
andreyandreev [35.5K]

The mother actually gives more DNA to a baby more than the father because of the little organelles, aka the mitochondria that live inside your cells are only to be received from your mother.

But in DNA, it can vary who's side you can get more of, and in some rare cases, equally. This is because dominant genes carry out around 75% of the time and genes that are recessive can carry out 25% of the time, depending on the genetics of both the mother and the father. Example, brown eyes are a dominant gene over blue eyes, so there is a 75% chance that the baby will have brown eyes and a 25% chance that the baby has blue eyes if one parent has the brown eye gene and one has the blue eye gene.

I hope this helped!! :D
