A. All four polysaccharides are homopolymers.
B. All four polysaccharides are heteropolymers.

Answer:

Option A

Explanation:

All four types of polysaccharides are homopolymers ie they are made up of repeating units of only one type of monomers.

Starch, glycogen and cellulose are made up of repeating monomeric units of glucose with the number of glucose units and the different linkage types different these molecules. E.g the linkage between glucose units in glycogen is alpha 1-4 linkages and in cellulose, we have glucose in beta 1-4 linkages.

In chitin, a derivative of glucose is present in repeating units, here, we have N-acetyl-D-glucosamine in beta 1-4 linkages.

Explain how the data from your experiments showed that cyanide was used to poison Jared, and that 2-deoxyglucose, arsenic and ol
Aliun [14]

The question is incomplete as the background of the case and symptoms of Jarod is not provided, however, the missing data required for the question is as follows:

Jared was investigating a drug cartel and ate a meal with one of the suspects. After the meal, he had trouble breathing and felt weak and dizzy. Jared may have been poisoned. He is being taken to the CIA hospital for treatment. You are a medical toxologist working for the CIA. It is your job to find out what poison was given to Jared and try to save his life. Patient: Jared Sondheim Age: 32 Occupation: CIA Agent Symptoms: Muscle Weakness Shortness of Breath Dizziness. Jared has arrived at the hospital! It is your job to find out what toxin was used to poison Jared. You can then give him the correct antidote to save Jared's life.

Answer:

Poisning by 2-deoxyglucose syops the glycolysis process which leads to cardiovascular and respiratory symptoms. Due to property of inhibiting the enzyme reqquired for glycolysis, glucokinase. So, there is no ATP production takes place.

Arsenic poisoning inhibits the second stae of cellular respiration, the Krebs cycle which leads to pyruvate accumalation. The symptoms associated with arsenic are diarrhea, sking tone, abdomunal pain, and muscle cramps.

Oligomycin is used as an antibiotic to inhibit proton ATPase present in mitochondria membrane which blocks ATP formation. Watery eyes, cough, congestion in chest and nose are sysmptopms of oligomycin poisining.

The symptoms cyanide poisoning are dizziness, short breath, nd muscle weakness which matches with the symptoms of jarod.

AleksAgata [21]

Answer:

B) Cells will pass through the G1/S checkpoint even if conditions are not ideal for cell division.

Explanation:

The cells will pass through the G1/S checkpoint even if conditions are not ideal for cell division. Because cyclin E is an activator of CdK 2 which stimulates functions of cell entry into S phase.

The most important regulators of Cdk are called cyclin proteins. Cyclines are a family of proteins involved in cell cycle regulation. Cyclines form complexes with cyclin-dependent kinase enzymes (Cdks), activating their kinase function in the latter.

Hope this helps!
