What are the different methods of transport across a membrane ?
dusya [7]
If I remember correctly, there are two main types of transport—passive and active. Passive transport does not require energy or ATP, whereas active transport does.


Types of passive transport include diffusion and osmosis, both of which involve moving down a concentration gradient and thus not requiring energy.


Active transport moves up the concentration gradient and does require energy.


Perhaps someone who has taken bio within the last several years can correct anything I might have misstated here.

How many red blood cells does your body make and kill in a seccond?
Andru [333]
 The average red blood cell lives for 120 days.

2. There are 2.5 trillion (give or take) of red blood cells in your body at any moment. To maintain this number, about two and a half million new ones need to be produced every  second by your bone marrow.That's like a new population of the city of Toronto every second.

3. Considering all the tissues and cells in your body, 25 million new cells are being  produced each second.That's a little less than the population of Canada - every second !

4. A red blood cell can circumnavigate your body in under 20 seconds.

5. Nerve Impulses travel at over 400 km/hr (25 mi/hr).

6. A sneeze generates a wind of 166 km/hr (100 mi/hr), and a cough moves out at 100 km/hr(60 mi/hr).

7. Our heart beats around 100,00 times every day.

8. Our blood is on a 60,000-mile journey.
