Which of these organisms lacks nervous tissue? a. sponge b. jellyfish c. nematode d. earthworm

The correct answer is A. Sponge

Explanation:

The nervous tissue is one of the types of tissue; this tissue is mainly composed of neurons that transmit and receive electrical signals; additionally, the main function of the nervous tissue is to control movement and process signals, besides it regulates some functions such as digestion. This tissue can be found in most organisms from mammals and complex organisms to worms.

However, in the case of sponges, these do not have nervous tissue as these are a simple multicellular organism that relies on filtering water for most functions and does not require a system for transmitting signals or moving. Also, besides lacking a nervous system, sponges do not have a digestive, and circulatory system.
