Answer 2
Answer:

Answer:

Light bounces off surfaces property most likely believed by Janssen about light during the time of his invention

Explanation:

Zacharias Janssen is ascribed as a man to discover the compound microscope. Its purpose is to amplify diminutive things so characters can analyze them. There is a mirror attached under the microscope and when light bounces off the mirror it reaches through and nearby the specimen being viewed.

Some elements do not receive light. When a light wave is reflected off a facade, it proceeds back off at an angle similar that the wave beats the surface. Using these more innovative concepts about light enacted scientists to compose new inventions.

Most living things need oxygen to survive. You breathe in oxygen and it is carried to this organ. Here the red blood cells pick up the oxygen and carry the oxygen to all the body cells that need it. What is this organ?A) diaphragm
B) heart
C) lungs
D) trachea

Answers

Answer:

The correct answer would be the C) lungs.

Lungs are the pair of air-filled spongy organs.

They are mainly associated with the exchange of gases (carbon dioxide and oxygen) in the body.

The alveoli are the group of tiny air-sacs present in the lungs which form the site of gas exchange.

The oxygen from the alveolar site diffuses into the blood and carbon dioxide from the blood diffuses into the alveolar site.

The oxygen is then transported to all cells of the body with the help of circulatory system whereas carbon dioxide is removed out of the body as a part of exhaled air.
C) the lungs.
The air moves down the trachea and into the lungs where it is picked up by the blood

Enzymes, such as the one shown in the picture, work by fitting onto the substrate molecule like a lock-and-key action. Which statement is true, with regard to the enzyme and the substrate?

Answers

Answer;

A)  The enzyme weakens chemical bonds in the substrate and catalyzes a change into the product. The enzyme itself remains unchanged.

Explanation;

  • Enzymes are biological catalysts that speed up chemical reactions. Enzymes catalyze or speed up a reaction by binding to a substrate using its active site.
  • The active site of an enzyme is suited to bind a particular substrate, that is why enzymes are known to substrate specific.
  • The binding of the substrate to the enzyme results to changes in the distribution of electrons in the chemical bonds of the substrate and consequently leads to  reactions that lead to the formation of products.
The enzyme weakens chemical bonds in the substrate and catalyzes a change into the product. The enzyme itself remains unchanged.

Why do people get asma

Answers

The most common way I believe you can get it is from another family member. Not in the sense that it's contagious, but that it's genetic. You can also get it from stuff in the air you might be allergic to such as dust or pollen. Diseases and infections in the chest will further provoke it. If you smoke, you are also more likely to get it. Also, if you are overweight it puts a strain on your lungs so your more likely to have an attack.
Well, It could be genetic, like if your mom has it then you might be likely to have it, 
It could also be because of exercising. . So when you work out  you could get it
It could also be due to cough or old age. 

Which of the following scenarios is representative of mutualism?a.
Barnacles living on whales
b.
Bees pollinating flowers
c.
Birds feeding on insects stirred up by grazing animals
d.
Mosses living on tree trunks

Answers

I think the correct answer from the choices listed above is option A. Barnacles living on whales is a scenario that represents mutualism. This is because both of the organisms benefit from their existence. Hope this answers the question. Have a nice day.
