Answer:
2) 25%
Explanation:
Let the traits for the black coat color be = BB
Let the traits for the brown coat color be = bb
Let the traits for heterozygous black coat color be = Bb
Now; the question says what is the probability of producing a rabbit with brown coat color from two rabbits that are both heterozygous for black coat color.
This implies that if two rabbits that are both heterozygous for black coat color cross together;
i.e Bb × Bb ;
The offspring will be (BB, Bb, Bb, bb)
BB (rabbits with black coat color) = 1/4
Bb (rabbits that are heterozygous for black coat color) = 2/4
bb (rabbit with brown coat color) = 1/4
Lets focus on ''bb'' ;
bb = 1/4 × 100%
= 25%
Answer:
During Anaphase stage
Explanation:
Meiosis is the type of cell division employed during gamete formation when each resulting gamete (daughter cell) has their chromosomal number reduced by half. Meiosis occurs in a two step division; Meiosis I and II. Meiosis I involves the separation of homologous chromosomes (similar but non-identical chromosomes received from each parent) while Meiosis II involves separation of sister chromatids (replicated chromosomes).
Alleles are present on the chromosomes which segregate or separate during the anaphase stage. Alleles received from each parent are separated in Anaphase I of meiosis I, which the identical replicated alleles are separated in anaphase of meiosis II.
Positron Emission Tomography scan of the brain of cocaine addicts showed that the drug affects how the brain use glucose. Cocaine users' brain cannot use glucose efficiently and there are also reduced metabolic activity in other areas of the brain.
106.5N
Explanation:
Given parameters:
Mass of cart = 75kg
Velocity = 4.4m/s
time taken = 3.1s
Unknown:
Force = ?
Solution:
To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".
F = m x a
F = force on body
m = mass of body
a = acceleration of the body
But we know that acceleration is the change in velocity with time of a body;
a = 
F = m x 
V is the velocity
t is the time taken
F = 
= 106.5N
