Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.
Answer:
Man: Bb
Man’s mother: bb
Woman:Bb
Woman’s father: bb
Explanation:
Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.
The correct answer is option (h) the breathing rate to supply more oxygen to cells for the release of energy.
Breathing refers to the process of inhaling oxygen and exhaling carbon dioxide from the lungs. A normal breathing rate at rest is around 15 breathes per minute which is significantly increased to 40 -50 breathes per minute during vigorous activity or excercise.
During exercise, the breathing rate, pulse rate and lactic acid levels increase in the human body. Muscle cells have an increased need for energy and heart pumps more oxygen to the muscle cells to meet the requirement. Breathing rate increases to supply more oxygen to the muscle cells which is required for the oxidation of the glucose, release of more energy and to get rid of the carbon dioxide.
Huh what that’s not an question
Answer:
Below
Explanation:
mRNA is a complimentary copy of a DNA segment (gene) and consequently can be used to deduce the gene sequence. For converting a sequence from mRNA to the original DNA code, apply the rules of complementary base pairing: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A).
The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain. The anticodon is the complementary three nucleotide sequence in the appropriate tRNA.
