Answer:

S-T segment of ECG shows ventricles contraction.

Explanation:

The ECG is used to measure the electrical signals that controls the contraction and relaxation of heart, most commonly known as heart rhythm. S-T segments are the region after the QRS wave in ECG which is further followed by T waves. The S-T segment is generally shown as a straight line as no electrical signal pass through it and this is the time when ventricles contraction in the heart takes place.

MArishka [77]

An isolated colony on a selective medium is not considered a pure culture because inhibited organisms might be masked by the colonies. This statement is true.

On the basis of their constitution or usage, culture media can be classified into various groups; these include defined, complex, selective, as well as enrichment medium.

A selective medium consists of dyes or noxious substances/chemicals which inhibit the growth of specific microorganisms but promote the growth of other microbes.

A pure culture is a laboratory culture which contains a single species of microorganism. It is free from other microorganisms.

Since selective media affects the growth of distinct organisms differently, therefore, an isolated colony formed in such type of medium is not considered a pure culture.

Through the digestion system, water is mainly absorbed in the A. gallbladder. B. stomach. C. large intestine. D. small intestine
bogdanovich [222]
I would say D. small intestine

If you want an explanation, here it is

After leaving the stomach, water is absorbed mostly in the early segments of the
small intestine, the duodenum, and the jejunum. A small portion of all water absorption occurs in the stomach and the colon: the small intestine absorbs 6.5L/day, whereas the colon absorbs 1.3L/day.
