Answer:
causes of food poisoning apart from bacteria include viruses, parasites and harmful chemical substance.
Explanation:
causes of food poisoning are
a) Viruses:These are very tiny germs made up of genetic material inside a protein coating
common virus that cause food poisoning is
norovirus and hepatitis A.
b). Bacteria:These are tiny organisms that can cause disease or infection. Bacteria that cause food poisoning include salmonella, Escherichia coli,and campylobacter.
c). Parasite are tiny organisms that live inside other organisms. Parasite can enter the body through food or water. Example of parasite that cause food poisoning is Gardia.
d) Harmful chemical: These maybe present in certain foods including fish, certain types of mushrooms and unwashed produce that contains large amount of certain pesticides
The sphincter pupillae muscle controls decreasing pupil size in response to brighter light levels. This action protects the eye from potential damage. The process is involuntary and controlled by the autonomic nervous system.
The pupil size in our eyes is controlled by two muscles: the sphincter pupillae and the dilator pupillae. When we are exposed to brighter light levels, the sphincter pupillae muscle contracts, which causes the pupil to decrease in size. This acts as a protective mechanism to prevent too much light from entering the eye and possibly causing damage.
The functioning of these muscles are involuntary and controlled by the autonomic nervous system. In contrast, in lower light levels, the dilator pupillae muscle would contract to increase pupil size and allow more light in for improved vision.

B. 5'-AAUGCGUA-3'
C. 5'-UACGCAUU-3'
D. 5'-AATGCGTA-3'
E. 5'-AUGCGUAA-3'
Answer:
E. 5'-AUGCGUAA-3'
Explanation:
The nucleotide sequence of the template strand specifies the nucleotide sequence of mRNA. Adenine in template strand pairs with uracil base in mRNA, thymine with adenine, guanine with cytosine and cytosine with guanine base. Also, the polarity of the DNA template strand and that of the mRNA is anti-parallel which means that 3' end of the template strand is present opposite to the 5' end of the mRNA. Therefore, a DNA template strand with nucleotide sequence 5'-TACGCATT-3' would code for the following mRNA:
DNA template strand: 5'-TACGCATT-3'
mRNA strand: 3'-AUGCGUAA-5'
the original cell theory.
the germ theory.
plate tectonic theory.
The Ptolemy's theory of the solar system was disproved by the discovery of the new information. The Ptolemy's theory stated that the Earth is at the center of the solar system and all the planets, suns and stars orbited around it while the Earth stayed completely stationary. However, this theory was proven to be false as the sun-centeric model of the solar system better explained various phenomenon, such as the particular movement of the planets.
Hence, the correct answer is 'Ptolemy's theory of the solar system'.
B. alleles
C. factors
D. chromosomes
The correct answer is Alleles
