Explanation:
animals often compete over common resources such as food and shelter
Answer:
B. 20%
Explanation:
The complementary base-pairing rule states that Adenine always pairs with Thymine (A with T), and Cytosine with Guanine (C with G).
Because of this, the amount of Adenine present must be the same as the amount of Thymine present, and the same for Cytosine and Guanine.
This means that if there is 30% Adenine, there is also 30% Thymine as each A base is paired to a T base. This adds to 60%, so Cytosine amounts and Guanine amounts must add to 40% to make 100%.
Since they are equal in amount, there must be 20% of each.
Therefore the answer is B. 20%
There is 30% Adenine, 30% Thymine, 20% Guanine and 20% Cytosine.
Hope this helped!
Answer:
The answers are explained below:
- Black rough fur -
. - Black smooth fur -
. - White rough fur -
. - white smooth fur -

Explanation:
- The genotype of homozygous black fur and smooth texture: BBrr.
- The gametes produced are : Br
- The genotype of white and heterozygous for rough texture: bbRr
- The gametes produced are : bR and br.
- The cross,
bR br
Br BbRr Bbrr
(B/R) (B/S)
- B - Black.
- R - Rough.
- S -Smooth.
- The cross can develop two types of offspring, that is,
- Black and Rough (BbRr) - 1.
- Black and smooth (Bbrr)- 1.
- Black rough fur -
. - Black smooth fur -
. - White rough fur -
. - white smooth fur -
