In aerobic cellular respiration the products are ATP, CO2, H20, where as the reactants are 02 and glucose
What is the difference between aerobic and an-aerobic cellular respiration ?Cellular respiration is just opposite to photosynthesis where glucose break down to produce energy in the form of adenosine triphosphate or ATP.
If It occurs either in presence of oxygen called aerobic respiration and in absence of oxygen called anaerobic respiration.
Aerobic respiration where organism combine oxygen with food substances and produce biochemical energy in the form of ATP, release carbon dioxide, and water as by product.
It occurs in inner membrane of the mitochondria.
Example is glycolysis.
Anaerobic respiration occurs in the absence of oxygen, involve break down of sugar into lactate and it occurs in Cytosol of cell.
Fermentation is example of anaerobic respiration.

A couple has three children, two without sickle cell anemia and one with sickle cell anemia. The mother has sickle cell anemia as well, while the father does not.
Make and defend a claim as to how this couple could have children with and without sickle cell anemia.
Answer:
Explanation:
The sickle cell allele is recessive. Hence, in order for any child of the couple to have sickle cell anemia, such a child will have to inherit an affected allele each from the two parents. This means that both the father and the mother must have affected alleles in their genotypes. In other words, two sickle cell alleles are required for the abnormality to manifest.
Let us assume that the sickle cell allele is represented by S and the normal allele is represented by A.
Now, it is established that the mother has sickle cell anemia, her genotype would be SS. The father does not have sickle cell, his genotype can either be AA or AS.
Assuming the genotype of the father is AA:
SS x AA
AS AS AS AS
All the children would be normal in this case.
Assuming that the genotype of the father is AS
SS x AS
AS SS AS SS
50% of the children would have sickle cell while the remaining 50% would be normal.
Therefore, in order to produce children with sickle cell, the father has to be AS, otherwise, he has to be AA.
If we found a way to repair a single cell with the DMD gene in a 2-year old child, could we cure DMD by repairing that single cell?
Answer:
No
Explanation:
because every cell will have that gene and you can't change a gene that was inherited from your parents.
No, there is no chance of curing DMD, by repairing a single cell with the DMD gene because it is a genetic disorder.
What is DMD?Duchenne muscular dystrophy, is the full form of DMD. It is a disease that cause weakness of muscles and leads to degeneration of muscles, it occurs due to change in dystrophin protein which is necessary to strengthen the muscles.
Thus, the correct option is No.

Describe what happens during interphase. Be sure to include all three parts of interphase.
Answer:
Interphase is divided into three subphases which are G1 phase, S phase and G2 phase.
Explanation:
During G1 and G2 phases, the cell grows by producing proteins and cytoplasmic organelles. Cell growth and cell differentiation occur. In the S phase, synthesis of DNA occurs. The chromosomes are duplicated and DNA has replicated to form two identical sister chromatids joined together by centromere. During interphase, the chromosomes are not visible but appear as thread-like structures, chromatin. In general. Interphase is the phase where the cell prepares for cell division. It involves synthesis of protein and organelles, growth, replication of DNA, cell differentiation and energy storage.

What is cancer ?
Cancer is a disease in which abnormal cell growth occur with the help of uncontrolled cell division and spread to other parts of the body. If it is fixed to one specific area of the body called as benign whereas if it spreads over different parts of body called as malignant.
In case of normal cell growth when human cells will grow and multiply to form new cells, when become old it will get damaged; In case of cancer mainly caused by genetic changes that control the way our cells function.
These Genetic changes that cause cancer include errors in cell division, damage of DNA due to harmful substances in the environment like chemicals in tobacco smoke and ultraviolet rays, also inherited from parents.
gamma rays which is the most powerful radiation energy could be focused to a pin point, and kill cancer cells with out harm the adjacent normal tissue, Now a days Gamma knife device is used to treat brain tumors.

how does sickle cell anemia mutation impact the structure and function of the protein produced
Answer:
The beta globin protein is one of the subunits of hemoglobin, a protein necessary for the oxygen-carrying function of red blood cells. People with the sickle cell mutation in both copies of the HBB gene produce proteins that clump together and lead to changes in the shape and behavior of red blood cells.
