Romashka [77]

Answer:

The lactose present prevents the production of lactase

Explanation:

This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.

According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.

Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.

Serhud [2]

Answer:

Gastro-esophageal reflux disease is a disease in which the upset stomach causes re-flux of acid back to esophagus. This may produce highly uncomfortable feeling of chest burn that may last even for two hours. GERD can get worse after eating because more volume of acids are released by stomach on detection of food like fast food and food that have high protein content. Patients are recommended to lose weight because that loses the pressure on abdomen a decreases the chance of GERD. Head elevation is also recommended to keep the acid within the stomach. It is same in while sitting upright after eating is recommended by doctors. GERD symptoms may have some respiratory complications like lung inflammation and chest congestion due to the action of stomach acid. This may lead to asthama.

What food chain is represented in the above food web?
fenix001 [56]
<span>B- tree > insect > frog> snake> hawk

The food chains are represented by organisms interconnected by red arrows that point in the direction of the one that's eating. So, the relation that is explicit by the arrow is that the organism from where the arrow departs is eaten by the organism where the arrow is pointing towards to. So, the food chain that can be observed accurately in the food web is: the tree is eaten by the insect, the insect is eaten by the frog, the frog is eaten by the snake, and the snake is eaten by the hawk.
