<h2>Answer:</h2>
Bacteria provide genetic engineers with <u>_vector_ </u>and <u>_host_.</u>
<h3>Explanation:</h3>
Vector are vehicles or carriers which are used to carry the gene of interest. They are usually plasmids which are bacterial circular genome which can replicate independently.
Hence bacterial plasmids are used for the insertion of gene of interest and its transfer to the host cell.
As plasmids is taken from the bacteria, so mostly bacteria is used as the host for the gene of interest.
Answer:
A
Explanation:
mtDNA is inherited from the mother of a child, this is because mitochondria are in the cytoplasm and the father's gamete (sperm cell) contributes very little or no cytoplasm to the zygote. We know that mitochondrial Eve came from Africa because the mutations in the mtDNA occurred before the <em>out-of-Africa dispersal</em>.
The answer would be Osmosis.
The correct answer is: C) thoracolumbar region, and the postganglionic fibers secrete norepinephrine
The pathway of autonomic nervous system (sympathetic and parasympathetic) involves two:
1. Preganglionic neuron - from CNS (spinal cord or brain) to the autonomic ganglion, all of these fibers release acetylcholine (Ach)
2. Postganglionic neuron - from the autonomic ganglion to the cells of the effector organ, parasympathetic postganglionic fibers release acetylcholine while sympathetic postganglionic fibers release norepinephrine.
