Answer: Stars?
Explanation: I think it is stars because there is only one star in our solar system. I don't know for sure if it is, but I think it is. Don't be too sure of my answer.
Answer:
The chloroplasts and lysosomes are the membrane-bound organelles that are not found in both...
Explanation:
Answer:
1. The initial decay rate is very fast, but the decay rate decreases over time.
2. Due to randomness, the last couple of radioactive atoms may take a long time before they become nonradioactive.
3. The pattern becomes very predictable.
4. Only a few radioactive nuclei are left to decay, so fewer and fewer atoms decay.
5. The rate of the decay decreases with each half-life cycle.
hope it helps!
Answer:
This is what I put (its kinda bad so don't judge)
Explanation:
A) Examining Table 1 with cancerous cells and HeLa cells we can see that with both HeLa and cancerous cells when treated with EGF increase in cells. Examining Table 2 we can see that HeLa cells create the most cells when treated with a concentration of 25 ug of EGF.
B) Normal cells increased by 33 when treated with a concentration of 10 ug of EGF. Cancerous cells increased by 405 when treated with a concentration of 10 ug of EGF. We can conclude from this that the cancerous cells multiply faster than normal cells with a concentration of 10 ug of EGF.
C) The mitotic index of HeLa cells with zero EGF treatment is 11 mitotic figures noted per 73 high power fields. The mitotic index of HeLa cells with 10 ug of EGF treatment is 8 mitotic figures noted per 90 high power fields. The mitotic index of cancerous cells with zero EGF treatment is 22 mitotic figures noted per 60 high power fields. The mitotic index of cancerous cells with 10 ug of EGF treatment is 27 mitotic figures noted per 465high power fields.
I'm on D right now so I'll put that in when I'm done with it
