<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.
The answer to this would be true.
Answer: alternating dark and light bandsof protein filaments
Skeletal muscle fibers contain striations that can be described as alternating dark and light bands of protein filaments. Actin, tropomyosin, and troponin are among the protein filaments. The dark bands are the so-called A bands. Alternating light bands are referred to as I bands.
Ontonic Pressure, or colloid osmotic pressure, is a form of osmotic pressure exerted by proteins, notably albumin, in a blood vessel's plasma (blood/liquid) that usually tends to pull water into the circulatory system. It is the opposing force to hydrostatic pressure.
