Jlenok [28]3 years ago
5 0

Answer:

a) and b) All the 12 plates taken by the food controller for the analysis are test plates in light of the fact that the food inspector is trying distinctive spinach from 10 unique bundles and do try different things with every one of the 12 plates.  

C) and D).only #11 plate is a negative control since he utilized the spinach which isn't cleaned. so microorganisms can develop on that pate because they have the positive condition to develop themselves.  

e) and f). all #1 - #10 and #12 plates are positive control plates since he swipes all the plates and spinach that can be the reason for the development of microbes so there is an excess of fewer opportunities to the defiling of spinach and he is playing it safe.

UNO [17]

Answer:

The correct answers are options B, D and E.

Explanation:

One of the essential parts of the innate immune system is the complement system. This system performs an essential function in elevating the tendency of antibodies and phagocytic cells to eliminate the pathogens. There are three biochemical pathways, which instigate the complement system that comprises the classical, alternative, and lectin complement pathway.  

The fundamental activities of the complement system are opsonization, cell lysis, chemotaxis, and agglutination. The process of cytolysis takes place through the complement pathway by the generation of membrane attack complex in the raiding cells. The complement pathway also leads to inflammation.

A research team needs an antibody that binds to a protein of interest so that protein expression can be monitored. They use epit
antiseptic1488 [7]

Answer:

C.The added epitope disrupts the function of the tagged protein

Explanation:

When an additional sequence is tagged to a protein to use comercial antibodies, there are several reasons why this procedure wouldn't work as expected (note that we're assuming the protein is being expressed but it's not possible to detect it).

For example, the sequence of nucleotide added to codify for the tagged epitope are removed during the RNA processing. In that case, the protein would be expressed without the epitope, so it would be impossible to localize it with the antibodies.

Also, it could be that the new epitope is affecting some way the protein folding, making it not functional. This way, it would be degraded by the cell so it wouldn't be detected.

Another possibility is that the epitope doesn't affects the protein folding nor its function, but during the folding ends up in a conformation that makes it inaccesible for the antibody.

In summary, the way as the possible answers to this question are shown, the correct option seems to be C:<em> The added epitope disrupts the function of the target protein.</em>

A neuromuscular junction is a junction between a_________ and a ___________. A neuromuscular junction is a junction between a___
garri49 [273]

Answer:

myofibril bulbous end of axon and skeletal muscles fibres.

Explanation:o

It represents the  chemical synapse  of the axon bulbous ends  of the motor neuron ( motor end plate) and the skeletal Muscle fibres.

The influx of calcium ions into the bulbous ends leads to the fusion  and empty of the vesicles containing neurotransmitters into the synaptic cleft.

The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or  PSEP)across the synaptic gap  to the muscles fibers  to initiate  their  contraction or relaxation.
