Hey there!
The main difference between deserts and steppes is the annual rainfall

No mitosis nor cellular respiration is not the same thing
You see mitosis is the division of cells and cellular respiration is using a more usable energy
So they are not the same
Answer:
0.0014; 0.0044
Explanation:
The absolute risk (AR) of a disease refers to the risk of developing the disease over a given time period. In this case, the absolute risk of the newborn African American child having sickle cell anemia is equal to 1 individual with the disease over 700 individuals >> AR = 1 / 700 = 0.0014. Moreover, the Relative Risk (RR) is calculated by comparing the likelihood of the absolute risk occurring between two distinct groups. In this case, the relative risk for the newborn African American having sickle cell anemia compared to a newborn European American child can be calculated by dividing the absolute risk of the newborn European American child with the measured absolute risk of the newborn African American child >> RR = 0.0000625 / 0.0014 = 0.0044.
Correct answer is D. The other choices are unsafe!

Answer:
The probability of an offspring of plants that are heterozygous produce plants with homozygous recessive genotype in ratio of :
RR : Rr : rr
(red) : hybrid : (yellow fruit )
1 : 2 : 1
Explanation:
Parental generation : RR rr
(red fruit ) (yellow fruit )
Gamete formation : R,R r,r
First filial generation : Rr (All are red because red is dominant )
Now let us cross the parents that is heterozygous Rr with homozygous rr :
Parental generation : Rr Rr
Gamete formation : R,r R,r
The second filial generation generation obtained :
R r
R RR Rr
r rR rr
The genotypic ratio :
RR : Rr : rr
(red) (yellow fruit )
1 : 2 : 1
Thus, the probability of an offspring of plants that are heterozygous produce plants with homozygous recessive genotype in ratio given above
