The ________ plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking a sample from the water blanks to add to empty petri plates which will be filled with melted agar.
The standard plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking a sample from the water blanks to add to empty petri plates which will be filled with melted agar.
The standard plate count is a method used in microbiology, which is used to gain an insight to estimate the density of bacterial population which is present in a bacterial culture broth. This is done by plating a small concentration of the culture in a petri-dish and then counting the colonies which form in the petri-plate. This method is used mostly in the food industry, to find the density of mesophilic bacteria in food. This method is extremely essential to determine the primary source of the bacterial contaminant.

Assuming that the rest of the genome is normal, cells with an inactivating mutation in one copy of a tumor-suppressor gene with the second copy of the gene still wild-type are most likely to_____.
Assuming that the rest of the genome is normal, cells with an inactivating mutation in one copy of a tumor-suppressor gene with the second copy of the gene still wild-type are most likely to show no changes in DNA sequence.
Tumor suppressor genes are normally present in the body. These function properly and keep processing the cell growth and cell death (apoptosis). It can also suppress tumor development. If both copies of a tumor suppressor gene is mutated then only it cause a change in cell growth and form a tumor. So these are recessive in nature. And if only one gene is mutated then it shows no mutation. When a tumor suppressor gene is inactivated by mutation, the protein it encodes is not produced or does not function properly, and as a result, uncontrolled cell division can occur. Such mutations can contribute to the development of cancer.

(c) Telomeres when cells divide.
What does the telomere do in the body?A chromosome's end contains a stretch of repeating DNA sequences known as a telomere. Chromosome ends are shielded from fraying or tangling by telomeres. The telomeres get a little bit shorter every time a cell divides. They eventually get so short that the cell can no longer successfully divide, and the cell then perishes.
With age, telomere length decreases. The health and lifespan of an individual are impacted by the progressive shortening of telomeres, which causes senescence, apoptosis, or oncogenic transformation of somatic cells. Reduced survival and higher illness incidence have been linked to shorter telomeres.

Homogenization, salt fractionation, column chromatography, Electrophoresis.Proteins called enzymes operate as natural catalysts for cellular non-spontaneous chemical events, starting and accelerating them. Despite their high turnover rates, they are picky and precise in their behavior.
Cell extract preparation, often known as cell lysis, is a stage of the capture phase. It entails liberating the cellular material from the host cells or tissue into an extraction buffer, producing the crude extract while preserving and stabilizing the target protein.The phenomenon known as "salting-out" occurs at very high ionic strengths, where protein solubility declines as ionic strength rises.As a result, salting out can be used to separate proteins according to how soluble they are in salt solutions.One of the most popular techniques for purifying enzymes is column chromatography. The foundation of chromatography is the idea that mixtures of molecules applied to surfaces or solids, and fluid stationary phases (stable phases), separate from one another while moving with the help of a mobile phase.Specific proteins in the blood can be measured using a test called protein electrophoresis.

How would an increase in the sympathetic nervous system increase stroke volume? decreased end diastolic volume increased end systolic volume increased contractility increased end diastolic volume
The correct answer is (c) increased contractility which increases the stroke volume.
Stroke volume is the blood volume that is pumped by left ventricle of heart during each systolic contraction or the difference in end diastolic and end systolic volume. Sympathetic nerves arise in the intermediolateral nucleus of lateral grey column near the middle of spinal cord.
Increase in the sympathetic nervous system increases the myocardial contractility because sympathetic nerves innervate the myocardium which as a result increases the stroke volume and heart rate and ultimately a higher cardiac output is observed.
Therefore, with increase in sympathetic nervous system stronger contactility is observed which results in higher stroke volume.

Finally it facilitates movement and exercise of the bowel , by prompting regular movement .
a short sequence of DNA is replicated using a mixture of dideoxynucleotide triphosphates, which lack a hydroxyl group at the 3' location. The new strands are separated from the old DNA
Sanger sequencing mimics the natural process of DNA replication by using dummy nucleotides to stop replication whenever a specific nucleotide is encountered. Because this truncated replication happens repeatedly, nucleic acids of various lengths accumulate and can be used to determine the position of each nucleotide in the sequence
ddNTPs are included (dideoxynucleoted)
A representation of 16 nucleotides arranged in a single horizontal strand of DNA is shown. Horizontal cylinders represent the deoxyribose sugar molecule and vertical rectangles represent the nitrogenous base in each nucleotide. The deoxyribose sugar and nitrogenous base of a single DNA strand are shown in grey. Below the single strand are four DDNTPs and four individual nucleotides. Sugar molecules are black in the bottom four DDNTPs in the bottom four individual nucleotides. To represent the bases' chemical identities, the nitrogenous bases on the DDNTPs and the lower four nucleotides are colored differently: DDATP is green, DDCTP is orange, DDTTP is red, and DDGTP is blue. Thymine is blue, cytosine is orange, and adenine is green.
DNA sequence :
DNA sequencing is the process of determining the order of the nucleotides within a gene. The first DNA sequencing methods were time-consuming, but a major breakthrough came in 1975 with the development of the Sanger sequencing method. Sanger sequencing is named after the English biochemist Frederick Sanger, and it is also known as chain-termination sequencing or dideoxy sequence. The Sanger method was used to sequence the human genome some 25 years after its invention, and it remains an important method in laboratories around the world today, despite many technological advances and modifications.
