What evidence can you find to describe whether the lungs are active

You have a 15kb plasmid. EcoRI cuts the plasmid into 7kb and 8kb pieces, and BamHI cuts the plasmid into 1kb and 14kb pieces. If

Harman [31]

Answer:

a. Bands at 1kb, 6kb and 8kb

Explanation:

The EcoRI and BamHI are the restriction enzymes which cut the DNA sequence especially a plasmid at specific sites called the restriction sites.

The restriction enzymes produces bands of specific length therefore these restriction enzymes are used to estimate the approximate length of the DNA.

In the given question, the

1. EcoRI- produces two strands of 7 kb and 8 kb

2. BamHI- produces two strands of 1kb and 14kb

This shows that the length of DNA sequence is 15kb

But when the DNA strand are digested with both the enzymes simultaneously then it will produce three bands as:

i) 14 kb can be broken down in 2 bands of 6 kb and 8 kb

ii) 1 kb band is already produced by the Bam HI.

This shows that 1+6+8= 15 kb

Thus, Option-A is correct.

select all of the following that are examples of how organisms respond to external stimuli. multiple select question. a person r

Airida [17]

The answer is a person removes their hand after touching a hot stove and a person turns their head toward the source of loud noise.

External stimuli are factors outside of the body that is taken in by receptors and will lead to a response. Examples of external stimuli include temperature changes, vision, hearing, tasting, smelling, and even sunlight for plants.

Why are aseptic procedures important in Microbiology laboratory health care industry?

Sever21 [200]

Answer:

Aseptic technique is important in the microbiology laboratory health care industry because it reduces the contamination risk that can have serious implications on the health of a person.

If aseptic procedures are not performed in the Microbiology laboratory and health care industry then there would be chances of getting the disease because in health care industries pathogenic samples from patients are processed which can be transferred in the employee while processing if correct aseptic technique is not used.

Aseptic procedures include wearing lab coats and other protective suits while working which cover all body and give protection from entry of pathogens. Sterilization of surface where work is going on, proper sterilization of all pathogenic cultures.

Therefore aseptic procedures are important to avoid contamination in the microbiology laboratory.

What is the role of carbon storage in organisms?? Plz answer fast in paragraph form if possible

belka [17]

Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
