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.
I can't be completely accurate without the texts, but based on my own knowledge I would have to say:
Explanation:
Yes, I think communities should use these green energies because not only does it keep the atmosphere safer and cleaner, it could help tremendously in the case that we run out of fossil fuels before we can find an alternative. Yes there are environmental risks, such as birds dying from wind turbines, but the lack of electricity might be more severe.
In Unicellular-reproduce organisms while Multicellular-repairs
dead or damaged cells. They both help
develop and grow. in the multicellular
this organism is made up of 2 or more cell they can be made up to trillion if
cells, it is much more complex than the unicellular. They reproduce asexually and the cells cannot
live outside the organism, they perform specialized functions an example:
nerves.
A numerical expression includes numbers and operations, so if youre wanting a numerical expression for the number 20, all you have to do is add, subtract, multiply, or divide numbers to equal that.
For example, 5+15=20, 4*5=20, 80/4=20, 29-9=20
Answer:
Explanation:
A cell is adapted to its function because of differential expression of genes during fetal development during which they get differentiated and determined to provide division of labour to different tissues. They contain protein fibres that can contract when energy is available, making the cells shorter.
