The correct answer is: B) continuous transcription of the structural gene controlled by that regulator

A regulatory gene is gene that encodes for a protein, such as a repressor (or activators) that controls the transcription of another gene or group of genes.

The regulatory gene of a repressible operon encodes for the repressor that inhibits gene transcription. So, when that repressor isn’t active, transcription occurs continuously.

Anton [14]

Answer:

X-linked recessive inheritance

Explanation:

Since the disease is primarily present in males vs females, it is a s.ex linked disease.

In X-linked recessive inheritance, males tend to get disease b/c they only have one x (the other is y) which means if they get the bad "x" copy from mom then they definetely will get the disease.

Females can be carriers b/c they are XX. If they get a good copy from mom and suppose a bad copy from dad, they can still be healthy b/c the good copy is dominant. They will be carriers (cuz they have the bad copy) but themselves wont have the disease.

Match the gastric phase on the left (1-3) with the correct description on the right (4-6):
dem82 [27]

Answer:

1 and 5,

2 and 6,

3 and 4

Explanation:

Intestinal phase: stomach empties and decreases secretions

The intestinal phase is the phase where stomach empties its contents(chyme) and decreases secretion. In this stage the duodenum responds to arriving chyme and moderates gastric activity through hormones and nervous reflexes.

The Chyme is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum.

Gastric phase: stomach secretes juice and mixes food into chyme

The gastric phase is a period in which swallowed food and semi-digested protein ( peptides and amino acids ) activate gastric activity  which secretes juice and mixes food into chyme. About two-thirds of gastric secretion occurs during this phase.

Cephalic phase: prepares stomach for arrival of food

The cephalic phase of digestion is the gastric secretion that occurs prior to when food enters the oral cavity. Cephalic phase result from the ignition of  visual, olfactory, and auditory inputs to the brain and also induce anticipatory responses i.e  prepare the gastrointestinal tract for the meal.
