Answer:

The correct answer will be option-E.

Explanation:

The nervous system is one of the most important systems of the animal body which helps in the transmission of the signals to and fro from the body to the nervous system.

The evolution of this system is the basis of the evolution of the human species as it helped and tried the species to sense the external environment most efficiently as well as improved the response to the environment.

The nervous system improved the response by forming new interactions with each other and responding to it by reducing the response time through reflex actions which formed fast acting response to the environment. The transmission of signals improved as the cells were long-lasting that is present form the birth of an organism

Thus, option-E is the correct answer.

Answer:

The correct answer is: Clostridium Tetani.

Explanation:

Clostridium tetani is a Gram-positive bacteria found in soil.

C. tetani may grow and generate tetanospasmin, a powerful toxin that interferes with motor neurons, producing tetanus, if introduced into a wound.

Tetanospasmin travels throughout the body via the lymphatic and bloodstream, where it is taken up by different sections of the nervous system. Tetanospasmin inhibits the release of the inhibitory neurotransmitters glycine and gamma-aminobutyric acid at motor nerve terminals in the nervous system. This blockage causes extensive motor neuron activation and muscular spasming. These muscle spasms usually start at the top of the body and work their way down, starting about 8 days after infection with lockjaw and progressing to spasms of the stomach muscles and extremities. The muscle spasms last several weeks.

Tetanus toxoid vaccinations, which are often given to children around the world, can inhibit the toxin's activity.

describes the study of microbes in their natural habitats and the relationships between the microbes and that habitat.

evablogger [386]

Answer:

The study of microbes in their natural habitat and their relationship with each other and their environment is termed as Microbial ecology. It mainly constitutes of Viruses, Eukaryotes ,Bacteria and Archaea as its living entities.

Being omnipresent in the biosphere they impact the other life-forms up to a significant extent.

They also help maintaining biogeochemical cycle by nitrogen fixation, sulfur metabolism and methane metabolism. Microbes also play a vital role of availing energy in the ecosystems where sunlight is scarce and hence photosynthesis is not good means of energy trapping, in such ecosystems the microbes actively engage in fundamental ecological processes including production, decomposition, and fixation inside the host organism.
