y the end of this lab, you will see how some materials diffuse through a semipermeable membrane but others do not. The materials

that you examine will differ in molecule size. Some will be larger and some smaller. Formulate an investigative question for this situation.

Imagine you are a red blood cell sitting in the right atria of the heart. Write a paragraph that describes what happens to this
alexandr402 [8]

Answer:

A red blood cell, sitting in the right atria of the heart is chocolate-brown in color since its a deoxygenated red blood cell with carbon dioxide rather than oxygen in its hemoglobin.

 

First

The tricuspid valve pumps it through the right ventricle

Secondly

pulmonary valve pumps it from the right ventricle to the pulmonary circulation.

Then

In the alveoli of the lungs, gas exchange occurs during pulmonary circulation

The end product is oxyhemoglobin( bright red colour) I.e oxygenated blood

The next step

pulmonary veins is the means whereby the red blood cell go to the left atria from the pulmonary circulation through the aortic valve

to mitral valve then to the aorta and systemic circulation

Therefore

oxygen is replaced by carbon dioxide during systemic circulation indicating a end to cellular respiration

Lastly

It's transported back to the right atrium of the heart completing the cardiac cycle.

The speed of light in a vacuum is approximately 299,500,000 meters per second. In scientific notation, we can write this number
Nonamiya [84]
In scientific notation, the value of the speed of light in a vacuum
 will be written as 2.995 * 10^8. When this value is represented in the form of
 a * 10^b, then, a = 2.995 and b = 8.
The value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. In this case, the scientific notation will be written as 3 *10^8.

If two parents display distinct forms of a trait and all of their offspring (of which there are hundreds) display the same new f
Ivanshal [37]
There has been a mutation and that mutation is a dominant trait. As both the parents have displayed the trait, there has been some reaction to the local environment that has improved or increased the survivabilty of the offspring related to this trait, so much so that the trait is now a characteristic that is dominant in the gene pool.
