Question 58 1 pts Name the tick borne disease caused by Ricketsii that acutely features a speckled rash on the wrists and ankles and may lead to long term damage due to intracellular pathogenic bacteria destroying epithelial cells of the blood vessels Name the tick borne disease caused by Ricketsii that acutely features a speckled rash on the wrists and ankles and may lead to long term damage due to intracellular pathogenic bacteria destroying epithelial cells of the blood vessels A) scarlet fever B) sequelea C) pyoderma D) Lyme disease E) rocky mountain spotted fever O sequelea Oscarlet fever sequelea Lyme disease

Answer 1

Note: According to Chegg rules and time constrain I am allowed to answer First 4 question, but I will try to cover as many as possible (as I have to provide you with a good explanation for your better understanding). If you want an answer for the rest please but them as separate question.

Answer 58:

NOTE: The options are incorrectly given in the question.

Option A (with the question contains the correct answer)

Rocky Mountain Spotted Fever is the disease caused by Rickettsia rickettsii a bacterium especially found on ticks and is the pioneer of the tick-borne fevers.

Options B & D are incorrect: Sequela is a pathological condition caused by some disease, injury, therapy or some other trauma.

Option C is incorrect: The scarlet fever is disease-causing symptoms of rashes, but these rashes are caused on the tongue. This disease is not spread by ticks.

Option E is incorrect: Lyme disease is also caused by a bacteria associated with a tick, but it is caused by Borrelia burgdorferi.

Answer 56:

Option C is correct. Bacterial conjugation is not a target for antibiotic drugs because bacteria can acquire antibiotic resistance from another bacterial strain via conjugation (a simple mating process common in bacteria).

Option A is incorrect. Bacteria contain a basic component in its cell wall called Peptidoglycan, these antibiotic drugs prevents the synthesis of this component and the cell wall get weakened and the bacterial cell cannot survive in the human body.

Option B is incorrect. The antibiotics which target bacterial protein synthesis actually attack the ribosome and inhibit its function so the bacteria are incapable of producing necessary protein to survive and eventually dies.

Option D is incorrect. Same as option A

Option E is incorrect. The antibiotics which target bacterial DNA synthesis mechanism hampers the mechanism of replication in bacteria i.e., it inhibits the action of DNA polymerase, inhibition of this process will lead to the death of the microbe without a genetic material.

Answer 57:

Option B is correct. The first observed antibiotic resistance was seen in penicillin-like antibiotic called methicillin, therefore the name "Methicillin-resistant Staphylococcus aureus and in present scenario MRSA is resistant to all beta-lactam antibiotics.

Option A is incorrect. No study has found it producing Shiga toxin.

Option C is incorrect. Yes, MRSA infection is pyogenic i.e., it accumulated pus in the lungs, but it is mostly treatable until the infection is chronic.

Option D is incorrect. The MRSA is not contagious. S. aureus always resides on our skin and will only enter our body through a cut on the dermis and in later stages when it becomes antibiotic-resistant, the infection is deadly.

Option E is incorrect. There is no study evidence of it showing hemolysis activity.

The question above "Question 55"

Option D is correct. Humans are an example of chemoheterotrophs, which depends on food from another organism. Glucose taken from the plant is the major source of energy in these organisms, which is broken down to simpler form through aerobic respiration while producing energy (ATP).

Option A is incorrect. Photosynthesis is a process of production of food by taking sunlight and carbon dioxide. It is the production of Glucose C₆H₁₂O₆.

Option B is incorrect. Methanotrophs are the organism which metabolises the monomer 'methane' for producing energy.

Option C is incorrect. Though they also depend on chemical reaction for energy, unlike chemoheterotrophs, these organisms can synthesis there own food and do not depend only on aerobic respiration for energy.

Option E is incorrect. Photoautotrophs are organism which does photosynthesis to produce their own food.

Please put the next question as different set, and always remember to not put more than 4 questions at once.

Thank You.!!!
