Answer:
The question lacks options and the incomplete punnet square; the incomplete punnet square has been added as an attachment while these are the options:
A) All red flowers
B) All pink flowers
C) 1 red : 3 pink flowers
D) 3 red : 1 pink flowers
The answer is D
Explanation:
According to the question, the genotype of a plant that produces red flower phenotype is about to be determined. For this flower colour gene, two alleles are involved in which the red color (R) allele is dominant over the pink color (r) allele I.e. the R allele will mask the expression of r allele in a heterozygous state.
The red-flowered plant with unknown genotype was crossed with a heterozygous red-flowered plant (Rr). Since a red flowered plant can either be Rr (heterozygous) or RR (homozygous), we use the Rr plant in the punnet square. The unknown genotype, assuming it has a Rr genotype, will produce RR, Rr, Rr and rr offsprings when crossed with another heterozygote (Rr).
These offsprings show a 3 red : 1 pink phenotypic ratio, making option D a valid prediction.
R r
R RR Rr
r Rr rr
Answer:
<h2> Mutant 4: can grow on minimal medium supplemented with T, P, or A.</h2>
Explanation:
In minimal medium, those bacteria who lacks some enzyme which are necessary for the synthesis of all their required compounds can not grow. They require these metabolites supplemented in minimal medium. In this case , if any of these 3 metabolites T,P,A which are required for the synthesis of H are absent in minimal medium,then there will be no bacteria growth.
Answer:
D) Mouth, pharynx, esophagus, stomach, small intestine, large intestine.
Explanation:
Food is ingested in the mouth, passes through the pharynx that connects the mouth to the esophagus. It moves down the esophagus by parastalsis. It is further digested in the stomach, absorbed in the small intestine and indigestible material together with fibre is passed to the large intestine where its either digested by freindly bacteria or eliminated as waste by defecation.
When you cut down a tree, there are rings on the inside of the tree. You can count these lines to help determine how old the tree is.
