Answer:
Smoking and cardiovascular disease
Smoking increases the risk of cardiovascular disease in several ways:
Smoking damages the lining of the arteries, including the coronary arteries. The damage encourages the build-up of fatty material in the arteries. This can lead to a heart attack or a stroke.
Inhalation of carbon monoxide in cigarette smoke reduces the amount of oxygen that can be carried by the blood.
The nicotine in cigarette smoke increases the heart rate, putting strain on the heart.
Chemicals in cigarette smoke increase the likelihood of the blood clotting, resulting in a heart attack or stroke.
Explanation:
The investigative question that would focus on the steps of the process of exploring the microscopic building of proteins from RNA would start with a 'how'. This is because how questions ask about the process. For example, 'How are proteins built from RNA?' would be a good investigative question.
No organism would survive.
Answer:
526.12 μm³
Explanation:
Given that;
A typical human cell is approximately 10.00 μm in diameter &
enclosed by a membrane that is 8.000 nm thick.
What is the volume of the cell including the membrane?
First, let's determine the radius of the human cell=
= 
= 
= 5 μm
Now, the radius of the cell including the membrane
= 5 μm + 8.000 nm
= 5 μm + 0.008 μm
= 5.008 μm
The volume of the cell including the membrane is given by the formula:
![V_{cell]= \frac{4}{3} *\pi *(r_{cell})^3 um^3](https://tex.z-dn.net/?f=V_%7Bcell%5D%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2A%28r_%7Bcell%7D%29%5E3%20um%5E3)
526.1160731 μm³
526.12 μm³
