Answer:
Explanation:
Imperfect science can be described as the scientific study of a research/field that is not complete or is characterized with a number of faults. While there are many scientific research fields or focus that fall under this category (because scientists are constantly seeking to improve existing knowledge of various scientific field), let's limit our scope to DNA evidence analysis.
DNA evidence testing for instance is very expensive which makes it difficult (in most cases) for victims to request for it in cases of crime (except requested by the government). For instance, if a killing that involves a struggle was done in a small neighborhood of about a 100 people with no visual confirmation of the killer but just some blood samples of the killer, DNA evidence testing might still not be used in a case like this despite the crime happening in a relatively small community.
Also, since DNA evidence testing relies on the gene and there is a lot of research going on at the moment on genes (including gene mapping and locus system) which can assist to lower the number of suspects by predicting the origins of suspects. It should be noted that reducing the number of suspects reduces the amount that will be spent on DNA analysis of the suspects (since there are fewer suspects).
Answer:
Capillary Exchange Mechanisms
Diffusion, the most widely-used mechanism, allows the flow of small molecules across capillaries such as glucose and oxygen from the blood into the tissues and carbon dioxide from the tissue into the blood.
Explanation:
RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.
siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.

Answer:
The correct answer is:
a)FADH2
c)GTP
e)NADH
Explanation:
The Citric acid cycle(TCA) also known as the <em>Kreb cycle,</em> is a focal metabolic center of the cell. It is a sequence of chemical reactions in which the acetyl portion of acetyl CoA is degraded to carbon dioxide and hydrogen atoms.These reactions all occur in the matrix of the mitochondria. This cycle is also an important source of precursor for other molecules such as amino acids, nucleotide bases cholesterol etc. The function of the citric acid cycle is the gathering of high-vitality electrons from carbon fuels. The citric acid cycle removes electrons from acetyl CoA and use it to reduce NAD and FAD into NADH2 and FADH2 respectively.
<em>Overall, The citric acid cycle oxidizes two carbon units(from acetyl CoA) and produces two molecules of carbon dioxide, one molecule of GTP and high energy electrons which are present in the form of NADH2 and FADH2</em>
