Why is it necessary to check total aerobic microorganisms in microbiological quality control but not to test total anaerobic microorganisms?
Answer:
While many microbes are harmless to humans, others can cause serious problems. They can spoil food, introduce toxins, cause disease and lead to a host of other problems. The importance of microbiological testing is to quickly identify these contaminants and treat them before they do irreversible damage.
Explanation:
Aerobic bacteria are bacteria that can grow and live when oxygen is present.
After fertilization occurs, the zygote undergoes cleavage and gets converted into 2,4,8 and subsequently a 16 celled stage known as morala. Thereafter certain changes occur in the morula and a blastocyst is formed. The blastocyst then gets implanted in the wall of the uterus.
A.3days
b. 6 days
c 10 days
d 14 days
Answer:
B. 6 days
Explanation:
I don't know a proper explanation, but overall it takes approx 6 days for the blastocyst to get implanted in the wall of the uterus.

The precursor of EGP is translated from a transcript that has had one non templated nucleotide added to the open reading frame. This change does not create or eliminate a stop codon. Compared with the protein sGP, which is produced from the unedited transcript, EGP most likely has the same primary:
Answer:
Explanation:
It was added somewhere in the middle. Since this is a frameshift, everything downwind of the addition will most likely be different.
The question is basically asking, if you change everything from the middle to the end of an amino acid sequence, which end changes and which end would remain the same?
It basically asks, when amino acids are assembled into proteins, are they built from the amino to the acid direction, or the acid to the amino direction?
The answer is that amino acid sequences are always assembled N to C, much like nucleotide sequences are built 5 to 3.
Why DNA synthesis is faster than RNA synthesis?is there any advantage of being faster?
Answer:
Explanation:
I read it's has to do with the amount of nucleic acid that must be synthesized. RNAs are tiny compared to DNA, so there is little selection pressure for speed. Also, multiple RNA polymerases can initiate simultaneously, effectively increasing the synthesis rate
Answer:An obstacle to the triviality of the first issue includes the fact that DNA polymerase replicates DNA at a rate of 10-15 times faster than RNA polymerase transcribes DNA so that these enzymes inevitably collide if they attempt to function concurrently and co-directionally
Explanation:
At any given instant, only a fraction of the genome (total DNA) is being transcribed. Consequently, speed is not necessary.

Answer:
the answer is osteon
Explanation:
A suspension of yeast cells is being grown under anaerobic conditions such that glucose is metabolized to ethanol and carbon dioxide. An inhibitor of alcohol dehydrogenase is added to the suspension, the cells rapidly die. Explain.
Answer:
The correct answer is - NAD needed to keep glycolysis going is not being recycled so the entire process is shut down and no ATP is produced
Explanation:
Alcohol dehydrogenase plays role in metabolizing the bulk of ethanol consumed as part of the diet and their activities contribute to the rate of ethanol elimination from the body.
Inhibitor of this zinc enzyme prevents it to perform its function which results in NADH generated during anaerobic conditions glycolysis cannot be recycled back to NAD+, So the ATP production pf anaerobic condition through glycolysis cannot be maintained.
In biological systems, there are several membrane transport systems responsible for the passage of ions like Na+ and K+.
a. True
b. False
Answer:
The correct answer is: a. True.
Explanation:
There are several membrane transport systems responsible for the passage of ions like Na+ and K+.
Cell membranes are semipermeable, which means they can regulate which molecules may and cannot flow through them. Some molecules may simply drift in and out of a cell (this is called simple diffusion), while others require specific structures to enter and exit (this type of diffusion is called facilitated diffusion), and still, others require an energy boost to pass the cell membrane (this is known as active transport).
Both simple diffusion and facilitated diffusion are types of passive transport: they happen without the energy boost that ATP gives, unlike active transport.
In passive transport, molecules follow their chemical gradients and travel through the most concentrated compartment to the less concentrated one to equal the concentrations. In active transport, on the other hand, the cell makes an effort to enter or exit ions against their chemical gradients and this is done particularly to maintain said gradients (they are required for the correct functioning of the cell).
Sodium and Potassium are two of the most important ions when it comes to maintaining these gradients: sodium is very concentrated in the outside of the cells (the extracellular compartment), while potassium is highly concentrated in the intracellular compartment. These differences in concentrations are maintained thanks to the Na+/K+ pump, a form of active transport. Apart from the Na+/K+ pump, these ions go through the membrane through passive transport as well, without requiring energy.

Answer: Air enters through the nose (and sometimes the mouth), moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi and bronchioles till the alveoli.
Explanation:The pathway of air in the respiratory system starts with the external organs of the nose and mouth.
Nose: Air is inhaled through the nostrils (and sometimes through the mouth) where it is filtered by the hairs and cilia to remove dust particles and moistened. The nasal cavity also moderates the temperature of the inhaled air.
Pharynx: This is a common passage for food, water, and air. It leads from both the nose and the mouth and leads to both the trachea (windpipe) and the oesophagus (foodpipe).
Larynx: This is the voice box situated just over the trachea and has a flap called the epiglottis which closes during swallowing to prevent food from entering the trachea and opens during breathing.
Trachea: Air now enters the windpipe which is situated behind the sternum (breastbone) and between the two lungs.
Bronchus: From the trachea, two bronchi (one bronchus for each lung) enter the lungs and divide and subdivide into secondary and tertiary bronchi, getting narrower as they proceed into the lung.
Bronchioles: The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air.
Alveoli:. Air ends its pathway in the alveoli (sing. alveolus) which are tiny sacs with very fine singe-celled walls. These alveoli are surrounded by capillaries that connect the pulmonary arteries and veins and that enable transfer of oxygen and carbon dioxide.

The CT reveals several issues with the cranial structure, one of which might be in the cribriform plate but the image isn't well defined. What non-invasive test can you do to test if the cribriform plate is severely damaged? Why?
The non-invasive test that can be used to test if the cribriform plate is severely damaged is called the pledget study.
CRIBRIFORM PLATE is the part of the ethmoid bone that forms the nasal cavity.
The olfactory nerve which is part of the cranial nerves passes through the small opening found in the cribriform plate.
A damage to the cribriform plate leads to cerebrospinal fluid (CSF) leak which usually comes out from the nose and ears.
Therefore to test if the cribriform plate is severely damaged, the pledget study is performed.
Pledget study is a non-invasive method of diagnosing a CSF leak.
To perform this test,
Cotton pads called Pledgets are placed in the nostrils.If the leaking fluid contains CSF it will be detected.The presence of CSF shows that there is damage to the cribriform plate.
This method is non invasive because it doesn't require the breaking or opening of any part of the body.

Explanation:
The sodium-potassium pump does not do which of the following actions?
-Moves sodium molecules against their concentration gradient into the cell
using ATP.
-Moves sodium molecules against their concentration gradient out of the cell
using ATP.
-Maintains the cell's physiological needs by establishing an electrochemical
gradient.
-Moves potassium molecules against their concentration gradient into the cell
using ATP.
The sodium-potassium pump does not allow the movement of sodium molecules against their concentration gradient into the cell with the use of ATP molecules.
In sodium-potassium pump, the sodium moves outside the cell whereas potassium moves inside the cell with the help of using ATP molecules. The sodium-potassium pump maintains the gradient of higher concentration of sodium extracellularly means outside the cell and a higher level of potassium intracellularly means inside the cell. This process is done only in the presence of ATP molecules that provides a force for the movement of sodium and potassium so we can conclude that no movement of sodium occur inside the cell in the sodium-potassium pump.
https://brainly.com/question/24347696
Answer: Moves sodium molecules against their concentration gradient INTO the cell using ATP.
Explanation:
The sodium-potassium pump moves sodium molecules against their concentration gradient out of the cell and moves potassium molecules against their concentration gradient into the cell. It also helps to regulate internal physiological needs through gradients. However, it doesn’t move sodium ions into the cell—that occurs through passive transport.
