Botulism is caused by endospores of C. Botulinum that have?

Question

a . been killed b. produced toxins. c. germinated. d. reproduced

Nitrogen is important because all organisms need it to make
a. proteins b. ATP C. DNA d. all of these

The process by which bacteria use enzymes to convert nitrogen gas into ammonia is called

A. Nitrogennation b. atmospheric separation c. nirtrogen fixation d. eutrophication

Answer 1

Botulism is caused by endospores of C. Botulinum that have?

Botulism is caused by b. produced toxins

Nitrogen is important because all organisms need it to make
Nitrogen is imporant in amino acids and nucleic acids as well as ATP so the answer would be d. all of these.

The process by which bacteria use enzymes to convert nitrogen gas into ammonia is called
by c. Nitrogen fixation

Answer 2

These bacteria exist either as spores or as vegetative cells. The spores, which are comparable to plant seeds, can survive harmlessly in soil and water for many years. When ideal conditions exist for growth, the spores produce vegetative cells which multiply rapidly and may produce a deadly toxin within three to four days of growth in an environment consisting of: a moist, low-acid food, a temperature between 40°F and 120°F, and less than 2 percent oxygen.

Answer 3

Botulism is caused by toxins produced by C. Botulinum

Nitrogen is found in amino acids and nucleic acids as well as ATP

Not certain on #3. It's either A or C, I suspect A.

Answer 4

b. produce toxins
d. all of these is right.
I just changed according to another answer because I looked at the chemical makeup of ATP, Amino Acids which both contain Nitrogen and Proteins are made of Amino Acids which have nitrogen.
c. nitrogen fixation
