Answer:
The different possible genotypes are AA, AO, BB, BO, AB, and OO. These are derived according to the A, B and O blood group model.
The table is given below:
Blood Type Genotype
Blood Type A Genotypes AA or AO
Blood Type B Genotypes BB or BO
Blood Type AB Genotype AB
Blood Type O Genotype OO
The alleles A and B exhibit a greater dominance than O. This is the reason why the Parent of Blood type A will form the Genotype AO.
Cigarette smoking decreases speed in track runner, due to the fact that their lungs have black spots. Making it harder for them to breathe. And harder to breathe causing slowing in speed.
Answer: Many people believe in extra-sensory perception, e.g. the ability to communicate with thoughts, to sense future events or locate radiation with the help of a V-shaped piece of wood. A majority of Americans - 57% - say they believe in psychic phenomena such as ESP (Extra Sensory Perception), telepathy or experiences that can’t be explained by normal means.
Explanation:
1) Cells duplicate their chromosomes before dividing instead of after because the daughter cells would each lose one-half of the genetic information.
The duplication of chromosomes automatically leads to the duplication of the genetic information on the chromosomes and each daughter cell receives a copy each of the genetic information.
If the information are not duplicated before dividing, it means that each daughter cell will receive half information.
2) If a cell that starts with 16 chromosomes lost half of its genes during each cell division, it will take 4 divisions for the gene to remain 1.
- First division, the genes would remain 8 from 16
- Second division, the genes would remain 4
- Third division, the genes would remain 2
- Fourth division, the gene would remain only 1.

<u>Answer:</u>
753.48 J
<u>Explanation:</u>
To increase the temperature of of m grams of water by n°C, you need to provide it with:
<em>heat = m x n x specific heat</em>
This will account for increasing the temperature of the first gram of water by n°C until you reach m grams of water.
q = mcΔT
where q = heat absorbed,
m = mass of sample,
c = specific heat of the substance; and
ΔT = the change in temperature
We know that the specific heat of water is 4.186 joule/gram °C so putting the values in the formula to get:
q = 9 x 4.186 x (20 - 0) = 753.48 J
