when a homozygous white rabbit (bb) is crossed with a heterozygous black rabbit (Bb). what proportion of white rabbits would the offspring have?
Answer:
Based on the Mendelian fashion cross,
bb is hetezygote reccessive.(white)
Bb is heterozyote dominant.(black)
Therefore,the the cross to show the proportion is below
Bb,Bb,bb,bb,
2 blacks(hetero zygote blacks) and 2 white.(homo zygote whites)
thus 2 of the offspring will be white, in 50%, of the number of offspring

Answer:
The correct answer will be- formation of membrane
Explanation:
The three-stage origin of life theory suggests that life on Earth originated in three phases which are:
1. Phase I: The larger molecules formation began during this unsuitable earthly conditions full of volcanic eruptions and harmful gases underwater.
2. Phase II: The self-replicating molecule begins to form during this phase which contained the coding of life. The self-replicating molecule is known as the formation of the membrane.
3.Phase III: The formation of the membrane which help separate the outer environment from the inner environment was observed during this phase.
Thus, the formation of a membrane is the correct answer.
Answer:
23 Chromsomes
Explanation
Thus, if a skin cell or somatic cell contains 46 chromosomes then the egg or sperm (gametes) would contain only 23 chromosomes
