A scientific Theory is a well-tested explanation for a wide range of observation or experimental results
2.1 false, Salive breaks down starch as it has amylase enzyme
2.2 true
2.3 false, small intestine
2.4 true
2.5 true
I’m not sure of all of my answers so i’m sorry if i got anything wrong.
when no oxygen is present, there is no electron acceptor, thus pyruvate goes through a process known as fermentation which usually forms lactic acid or ethanol as a by-product. During lactic acid fermentation, pyruvate is reduced directly by NADH to form lactate as a waste product, with no release of CO2.
Answer: Phenotype ratio is two heterozygous round pea : two homozygous wrinkled pea
Probability of getting a wrinkled pea is 1/2
The number of flowers that are homozygous is 2
The probability of getting a round pea is 1/2
Genotype ratio = 2 Rr : 2 rr
Explanation: From the information provided, round pea R is dominant while wrinkled pea r is recessive. A monohybrid cross between a heterozygous round pea Rr and a homozygous wrinkled pea rr will produce four offsprings, two of which are heterozygous round pea Rr and the other two are homozygous wrinkled pea rr.
The genotype ratio is 2 Rr : 2 rr while the phenotype ratio is two heterozygous round pea : two homozygous wrinkled pea. Heterozygous round (Rr) peas will manifest outwardly as round pea because R is dominant while r is recessive.
Since two out of the four offsprings are homozygous wrinkled pea, therefore the probability of getting a wrinkled pea is 2/4 = 1/2. Also, two out of the four offsprings are heterozygous round pea, therefore the probability of getting a round pea is 2/4 =1/2.
Since, only the two wrinkled peas are homozygous, therefore the number of flowers that are homozygous is 2
<span>I believe that the answer is a. one day. After the egg leaves the ovaries it then travels to the fallopian tube where it sticks there waiting for it be fertilized. After a 24 hours of sticking in the fallopian and fertilization made. The ripe egg disintegrate and then either flies out of the body or absorb by the body.</span>
