Answer:

Two synapses.

Explanation:

Synapse or Synaptic cleft is the space two neurons or between a neuron or target organ where the signal is carried by neurotransmitter. Nerve signal first travel through interneuron to motorneuron passing through the first synapse, then the signal will travel to effector organ from motor neuron by passing through second synapse.

What are restriction enzymes and how are they used to cut DNA?
Colt1911 [192]

Answer and Explanation:

A restriction enzyme is a type of endonuclease enzyme  that recognizes  a specific short nucleotide sequences on the DNA and  cuts the DNA only at palindromic sites. There are different types of restriction enzymes:

1. Type I restriction enzyme – It cuts at sites far  from the recognition site and requires both ATP and S-adenosyl-  L-methionine as cofactor to function.  

2. Type II restriction enzymes – It cleaves at short-specific distances from the recognition  site and mostly  requires magnesium to function.

3. Type III restriction enzymes – It recognizes two  separate non-palindromic sites and cleaves at 20–30 base  pairs away from a recognition site. It requires both ATP  and S-adenosyl-L-methionine  .

The restriction enzymes cleave DNA sequences producing either sticky or blunt ends that can be ligated with other sequences.

Giardia does it lead to elevated levels of IgE and eosinophilia?
vaieri [72.5K]

Answer:

No, Giardia is a protozoan that does not cause eosinophilia.

Explanation:

Eosinophilia refers to an increase in the number of eosinophils in the blood. The eosinophil is one of the white blood cells. When this occurs, the circulating eosinophils might be over 400 or 500.

Many factors might cause. One of them is parasite infections, in which helminths trigger the IgE generation, producing eosinophilia.

In the presence of the parasite antigen, eosinophils have a shorter medullar generation time, and they express a higher number of receptors for IgE and IgG. Their function is to damage the parasite, directly or indirectly, and to decrease the damages caused by their presence.

Giardia, among other protozoans, does not cause eosinophilia. Yet some other protozoans and parasites might induce it.
