What is a recombinant plasmid?
Mkey [24]

Answer:

DNA plasmid that contains both "old" and "new" gene segments and confers new characteristics to the organism in which it is placed.

Explanation:

During the genetic engineering procedure, which aims at producing an organism with better and desirable characteristics, a DNA called PLASMID is usually used to convey the gene of interest into the organism.

A plasmid is a self-replicating extra-chromosomal DNA found in the bacterial genome. The plasmid becomes a RECOMBINANT PLASMID when a foreign DNA of interest is inserted into it, in order to act as a vector (carrier). Therefore, a recombinant plasmid is a DNA plasmid that contains both "old" i.e bacterial genome and "new" i.e foreign gene segments and confers new characteristics to the organism in which it is placed.

Give the definition of parasympathetic nervous system?
SashulF [63]

Answer: Autonomic nervous system is made up of 3 divisions; Sympathetic nervous system, parasympathetic nervous system and sympathetic division. All these divisions are involuntary actions where parasympathetic is ultimately responsible for the "rest and digest" part of it. When the body is at rest the parasympathetic nervous system inhibits or lowers high energy requiring bodily functions.

This nervous system will lower any fight or flight response actions such as the release of epinephrine into the blood and enable digestion, urination and defeacation. When engaged in digestion you feel relaxed and at rest, this is solely due to the parasympathetic nevous system.

postnew [5]
Tigers are a very important part of the food chain, but sadly they are going extinct. Their habitats are being destroyed, forcing the tigers to kill farmers livestock. In some countries tigers are still used for medicinal purposes, so they are often hunted for their teeth and pelts. Tigers may not seem important but they play a very important part on the food chain. Without these tigers the population of boars and other prey would sky-rocket and that would not be good for the environment.

What’s is the unit ratio of platelets to whit blood cells in a microliter of blood?
____ [38]

Answer:

33.3

Explanation:

Normally there are 4000 to 11000 WBCs in a microliter of blood averaging almost 7500. While there are 150,000 to 350,000 platelets in a microliter blood of a normal person averaging almost 250,000. Thus the ratio can be as 250,000 :7500 resulting in 33.3. If a range is to be given, it ranges from 31.8 to 37.5 per microliter of blood.
