Which animal kingdom does the organism that causes plague belong to?
aniked [119]

Answer:

Plague is caused by Yersinia pestis. It is unicellular and placed in the bacteria domain.

Explanation:

Plague is caused by bacteria Yersinia pestis , a zoonotic bacteria usually found in the small mammals and their fleas. It is a gram-negative, nonmotile, rod-shaped, coccobacillus bacteria, with no spores. It is a facultative anaerobic organism that can infect humans via the Oriental rat flea.Y. pestis was discovered in 1894 by Alexandre Yersin, a Swiss/French physician and bacteriologist from the Pasteur Institute, during an epidemic of the plague in Hong Kong. Yersin was a member of the Pasteur school of thought. Kitasato Shibasaburō, a German-trained Japanese bacteriologist who practised Koch's methodology, was also engaged at the time in finding the causative agent of the plague. However, Yersin actually linked plague with Y. pestis. named Pasteurella pestis in the past, the organism was renamed Yersinia pestis in 1944.

HELP!!<br><br> What are the steps from gene to protein? Label and describe each step.
Alika [10]

DNA makes up genes. Transcription: The info stored in the gene's DNA is transcribed to RNA in the cell nucleus. The type of RNA that contains the info for making a protein is called messenger RNA, also known as mRNA. It carries out the information from the DNA, out of the nucleus, and into the cytoplasm. Translation: This happens in the cytoplasm. It is where the mRNA interacts with the ribosome, which "reads" the sequence of mRNA bases. Three bases make a <em>codon</em>, which usually codes for one particular amino acid, which is building blocks of proteins. Then, another type of RNA called transfer RNA, aka tRNA, assembles the protein by folding. This continues until the ribosome reaches a stop codon.

What would happen if you fed termites a drug that killed trichonympha?
yaroslaw [1]
<h2>Answer:</h2>

Termite will not perform its function which is digesting cellulose. Hence termite will unable to decay woods.

<h3>Explanation:</h3>

Termites and trichonympha ( a protist ) are in symbiotic relation. Trichonympha lives in the hind gut of a termite. Termites give a home to trichonympha while trichonympha produce an enzyme which is used by termites to digest cellulose. So without trichonympha, there will be no enzyme and no digesting activity by termites.
