Question

________________ signaling can occur over relatively long distances in a multi-cellular organism. _____________ signaling occurs over relatively short

Answer 1

The correct answer will be-

1. Endocrine signaling

2. Paracrine signaling

Step-by-step explanation:

In multicellular organisms, the cells communicate with each other through one of the three ways that are endocrine, paracrine and autocrine signalling.

The cells communicate with each other in very short distances through the release of chemical messengers through a mechanism called paracrine signalling. Paracrine signalling allows the coordination of cellular activities locally.

The cells present at long distances in the body communicate with each other through the production of the chemical messengers called hormones. This type of communication is known as endocrine signalling. It is one of the most common methods of communication.

Thus, 1. Endocrine signalling and 2. Paracrine signalling is the correct answer.
