Answer:
C) the phrenic nerve that serves the diaphragm receives its fibers from here
Explanation:
Description:How an X-ray diffraction pattern is created and how the DNA X-ray diffraction pattern can be interpreted to give the dimensions. (DNAi location: Code > Finding the Structure > piece of the puzzle > Franklin's X-ray)Transcript:This is the X-ray crystallograph pattern of DNA obtained by Rosalind Franklin and Raymond Gosling in 1952. It is know as the B-form. It was clearer than the other X-ray patterns because water was included in the DNA sample. Both James Watson and Francis Crick were struck by the simplicity and symmetry of this pattern. The distinctive "X" in this X-ray photo is the telltale pattern of a helix. Because the X-ray pattern is so regular, the dimensions of the helix must also be consistent. For example, the diameter of the helix stays the same..........Keywords:x ray diffraction,x ray crystallography,rosalind franklin dna,diffraction pattern,ray pattern,s college
The resulting mice will be induced with the changed gene either on or off. The offspring will have altered genes if both the alleles have the trait. This is a heritable change.
Explanation:
Making gene on or off is a process of gene regulation when one of the gene is methylated or histone modification to prevent access to transcription factors hence no expression of the protein. This process is called epigenetics.
The resulting progeny in mice will receive the allele of on or off the gene. Such genes with altered allele are also called as
The altered genes will be expressed in the resulting progeny of mice.
The epigenetic genes can be reverted with environmental effects in the offspring paramutable alleles. They are heritable.
Answer:
D. DDT
Explanation:
DDT is highly persistent in the environment means that it break down very slowly in the environment. The half-life for DDT is from 2 to 15 years. Half-life is the time needed for the degradation of half of the compound. Persistent bio-accumulative toxic substances (PBTs) are chemicals that break down slowly in the environment and its accumulation in living organisms are toxic. Some PBTs are dispersed through air currents while some uses other environmental pathways, resulting in contamination of regions far from their points of origin.
Answer:
The electron transport chain may be defined as the sequential steps of the oxidation and reduction of the cytochromes. The electron transport chain is important for the production of ATP.
The gramicidn protein is an ionophoric antibiotic that can affect the electron transport system. The electron transport rate, oxygen uptake and proton pumping remains the same as more hydrogen ions will enter in the cell. But the ATP synthesis rate might decrease and completely stop by using gramicidin.
