Strep throat food poisoning and anthrax are all diseases caused by the following
a. fungi
b. virus
c. protist
d. bacteria

The correct answer is D.

Streptococcus pyogens is the bacteria responsible for causing sore throat. It produces  some toxins called streptolysins. These toxins destroy red blood cells and  can cause severe disease and even toxic shock.

Food poisoning is caused by bacteria. The most commonly implicated ones are Bacillus cereus, Campylobacter jejuni, Clostridium botulinum and Clostridium perfringens.

Anthrax is also caused by a bacteria known as Bacillus anthracis. This bacteria produces toxins that cause severe disease. It is usually transmitted from infected animals and animal products.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
