Answer:
50%
Explanation:
DNA replication is a semi-conservative process. It means that after DNA replication, the newly formed DNA molecules have one parental strand and one newly formed strand. The cells in the experiment have DNA with 15N. After one round of DNA replication, each DNA molecule would have one parental DNA strand with 15N and one newly formed DNA strand with 14N.
However, after the second round of DNA replication, each hybrid DNA with strand having 15N and the other with 14N would be unwound. The parental heavy DNA strands would be present in the 50% of the newly formed DNA while the rest 50% of DNA molecules would have both strands with 14N (both light strands).
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.
Answer: A. scalp hairs grow constantly throughout life.
Explanation:
Hair is a squamous keratinized epithelium which is consist of multi-layered flat cells. Hair are made up of protein called "keratin".
The statement "scalp hairs grow constantly throughout life" is false because at a particular age or due to several factors scalp hairs stop growing.
Scalp hair growth rate depends on three main factors including sex (female hair grows faster than male), age (hair growth slows with age), and ethnicity (Asian hair grows slower than Caucasian hair).
Scalp hair growth stops because of follicle devitalization when the hair length become two or three feet.
Hence, the correct answer is A. "scalp hairs grow constantly throughout life".
Answer:
1.25 µm
Explanation:
The cell will have a length dimension that is 1/40000 times the length of the image:
(50·10^-3 m)/(40·10^3) = 1.25·10^-6 m = 1.25 µm
The answer is <span>bird droppings that contain seeds from a different location.
</span><span>Gene flow includes a transfer of alleles from one population to another. So imagine a population of plant A on location 1 and another population of plant A on location 2. They cannot interchange their genes. But if birds drop seeds from location 1 and those seeds get to location 2, gene flow may occur.</span>
