How do scientists use recombinant DNA technology to produce the drug insulin?

Biology
1 answer:
Papessa [141]3 years ago
7 0
First, scientists isolate the gene that controls insulin production. Then, they take that gene and insert into a plasmid (a circular ring of DNA found in bacteria). When the bacterium with that plasmid reproduces, it carries that insulin-producing gene. Then they can either mass-reproduce that bacteria or transfer the plasmid to another rapidly-reproducing bacteria. After some time, they harvest the insulin from the bacteria.

How does oxygen diffuse within the lungs? a. It diffuses from the capillaries into the veins. c. It diffuses from the alveoli in
Nookie1986 [14]

The answer should be C, It diffuses from the alveoli into the blood.


Alveoli, also called the air sac, is the place where the oxygen we breathed in is exchanged with carbon dioxide that our body produces. Oxygen is passed into the blood in the capillaries through the process of diffusion, while carbon dioxide is diffused from the blood back to the alveoli, so that we can exhale the carbon dioxide after that.


Both a and b are not right because when we breathe in, the oxygen travels from the trachea to the bronchi, to the bronchiole, and to the alveoli, instead of directly into blood vessels like arteries, capillaries, or veins. d is also not right because the direction is wrong.


Therefore, your answer should be C.

AB+CD (reactant~higher on graph) ---> AC+BD (product~lower on graph)
amid [387]

Answer: Option E) the products have less potential energy than the reactants

Explanation:

Though the actual graph is not displayed, but, whenever reactants occupy a position higher than the product on the graph of reaction coordinate vs time taken, it means the reactants (AB+CD) have molecules with higher energy bonds than the products AC +BD

Thus, the reaction of AB + CD to yield AC+BD will occur spontaneously with the release of energy.

There are 2,000 mice living in a field. If 1,000 mice are born each month and 200 mice die each month, what is the per capita gr
Ivan

For 2,000 mice living in a field,  the per capita growth rate  is mathematically given as

NT=0.4

<h3>What is the per capita growth rate (rmax) of mice over a month?</h3>

Generally,  the birth and death rate  is mathematically given as

BT=1000/2000

BT=0.5

Where

DT=200/2000

DT=0.1

In conclusion, per capita growth rate

NT=0.5-0.1

NT=0.4
