Solution:
The most appropiate unit of measurement fro most types of cells is CD4 counts are measured in cells per cubic millimetre = cells/mm3. A cubic millimetre (mm3) = mm3 = 1 mm x 1 mm x 1 mm.
This is the required answer.
Answer:
Release of electrons from reducing powers to O2 via four protein complexes allows release of small amount of energy at each step and makes the process energy efficient.
Explanation:
If NADH and FADH2 would reduce O2 directly, a large amount of energy would have been released in a single step. On the other hand, oxidation of these reducing powers through a series of electron carrier release a small amount of energy at each step which in turn is temporarily stored in form of proton motive force across the inner mitochondrial membrane.
Transfer of a pair of the electron to O2 pumps four protons by complex I, four by complex III and two by complex IV. The resultant proton motive force effectively stores the energy of electron transfer. This energy is then used to drive ATP synthesis.
Answer is in the attachment.
Answer:
The DNA is a double stranded nucleotide. The DNA is consisted of deoxyribose sugar, phosphate group, and nitrogenous bases such as adenine, thymine, guanine, and cytosine.
The adenine always base pairs with thymine, so whatever the percentage of an adenine in a DNA strand is, always the same with thymine. Same thing with Guanine as it always base pairs with Cytosine.
A = T
G = C
Explanation:
Let's take the cow as an example.
If its adenine content is 28%, it has also 28% thymine content. 28 + 28 = 56% So, the remaining percentage is G and C, which is 44%. The 44% will be consisted of 22% guanine and 22% cytosine, making it 100%.

Answer:
Transduction
Explanation:
Among the three types of gene transfer in bacteria, transduction does not require physical contact between the two bacteria cell. Viruses that infect bacteria accidentally move pieces of chromosomal DNA from one bacterium to another. These viruses that infects bacteria are called bacteriophages.
Simply put, transduction is a process of genetic recombination in bacteria which involves the incorporation of the genes of a host cell (bacterium) into the genome of a viral cell (bacteriophage) and then conveyed to another host cell when the bacteriophage infects it. The process of transduction is of two types; generalized and specific depending on whether any gene or specific gene is transduced respectively.
The aim of these viruses when they infect bacteria cell is to harness the ability of bacteria to replicate, transcribe and translate their genetic material and use it to procreate into many virons or complete their viral particle.
