ziro4ka [17]

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.

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.

How much heat is needed to raise the temperature of 9g of water by 20C
Vilka [71]

<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
