What happens to the expression of the lacI gene if lactose is not available in the cell? View Available Hint(s)

Biology
1 answer:
olchik [2.2K]3 years ago
3 0

Answer:

There is no change, the lac l gene is constitutively expressed, regardless of the presence of lactose.

Explanation:

Lacl gene codes for the lac repressor hence is always expressed to produce lac repressors which may or may not be bounded dependent on the presence of lactose. Lacl gene expression is not regulated, thus is constitutively expressed.

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.

the esophagus is the tube that connect the mouth to the stomach. heartburn occurs when some kf the stomach juives flow backwards
beks73 [17]

<u>Answer:</u>

To help relieve heartburn, a person should take medicine that is 'Over-the-counter (OTC) antacids and acid blockers'.

<u>EXPLANATION:</u>

  • Heartburn is a very common symptom of a condition called Gastroesophageal reflux disease.
  • This affects the lower part of the esophageal sphincter and also the muscle ring-like connection between the 'esophagus and stomach' which tends to infuse a backward flow of the stomach secretions.
  • Along with some dietary and life style changes, the intake of antacids and acid blockers can help in the relieve of the symptoms of occasional heartburn.

Heart rate decreased suddenly and then MAP immediately fell because peripheral blood vessels were extensively vasodilated.

Explanation:

A VO2 max test is a clinical test done in a lab and is the ‘golden standard’ for measuring the potential and cardio-respiratory endurance of athletes and bikers.

It measures the oxygen carrying capability through a graded step test which determines the average power output. The maximal oxygen uptake along with cardiorespiratory responses is measured.

As per exercise physiology, the heart rate and cardiac output increases with exercise. When the potential is less, the resistance decreases, heart rate and mean arterial pressure also decrease .
