This is because it has many parts, arteries, and tubes that pass blood around the body. It is hard because it has many parts which are difficult to be cut open. Hope I helped!
Answer:
<em>Bright white fur 3/4</em>
<em>Black fur 3/16</em>
<em>brown fur 1/16</em>
Explanation:
From the Punnet's square analysis (see the attached image);
- <em>A_B_ 9/16 </em>
- <em>A_bb 3/16</em>
- <em>aaB_ 3/16</em>
- <em>aabb 1/16</em>
A_B_ and A_bb will always give offsprings with bright white fur since allele A always mask the effect of B.
aaB_ will always give offsprings with black fur since allele a does not produce any protein.
aabb will give offsprings with brown fur since b codes for brown fur colour.
Hence, the phenotypic ratio of the offspring will be;
<em>Bright white fur 3/4</em>
<em>Black fur 3/16</em>
<em>brown fur 1/16</em>
Answer:
The correct answer is: 600,000 years
Explanation:
Half-life is the time which is essential or required to decrease a specific substance to half of its initial amount of the substance. So, if a substance has a half-life of 200,000 years then it means it takes 200,000 years to decrease or change into a new substance and remain half of its initial quantity.
half-life amount
0 20000
1 10000
2 5000
3 2500
total half-life = 3 to 2500 atoms of A
so, the time will be = 3 * 200,000 years
= 6000000
The correct sequence is -
B , E , A , C , D
