Radda [10]

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.

What might hershy and chase have concluded if they had found 35s instead of 35p in bacterial cells? Explain your answer

kaheart [24]

Hershey and chase have concluded that DNA is not protein it was the genetic material.

Explanation:

Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.

The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.

The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.

Can ground tissue do photosynthesis

Damm [24]

The major cells of the ground tissue are parenchyma cells, which function in photosynthesis and nutrient storage. They have thin walls, many chloroplasts, and large central vacuoles, and they form the mass of most leaves, stems, and roots. Another cell of the ground substance is the sclerenchyma cell.
