Answer:
adenine = 26%
guanine= 24%
cytosine=24%
Explanation:
adenine=thymine
then 100 - (adenine+ thymine)= cytosine+guanine
Answer:
Genotypic results: 1 (TT):2 (Tt) :1 (tt)
Homzygous Dominant: 1/4
Heterozygous: 1/2
Homzygous Recessive: 1/4
Phenotypc results: 3 tall: 1 short
Tall: 3/4
Short: 1/4
Explanation:
This question involves a gene coding for height. The alelle for tallness (T) is dominant over the allele for shortness (t). According to this question, a cross between two Brassic rap parent plants known to be heterozygos tall (Tt) is performed.
Each parent will produce gametes T and t. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
TT (1), Tt (2), and tt (1)
Based on this result, the following results are obtained:
Genotypic results: 1 (TT):2 (Tt) :1 (tt)
Homzygous Dominant: 1/4
Heterozygous: 1/2
Homzygous Recessive: 1/4
Phenotypc results: 3 tall: 1 short
Tall: 3/4
Short: 1/4
Answer:
The sensory neuron receive the stimulus by tapping at the knee cap and its going to send the message all the way to the spinal cord. And then it will make a U-turn and they will send the message back to motor neurons and then back to the knee cap so that the muscle will contract and your knee will just kick up.
Explanation:
Answer:
1) transport process, 2) removing waste, 3) reproduction, 4) produce energy
Answer:
C) Because apoptosis genes kill cells, natural selection is seldom involved in apoptosis pathways.
Explanation:
Apoptosis is a natural process taking in the cell which causes the physiological and biochemical changes in the cell which could cause the death of the cell.
The apoptosis is controlled at the genetic level therefore apoptosis is also known as the programmed cell death.
The studies have shown that the process is involved in the development of the finger and the toes in humans and the sequences controlling the process has been conserved during the evolution in a different organism.
This shows that humans and nematode have the same conserved sequence of apoptosis but the natural selection does not control the apoptosis.
Thus, the selected option is the correct answer.
