History of Present Problem:
Frank was driving home after a long day at work. It was late and he was having problems driving in the dark with so
much traffic. He was forced to take a detour and felt tired, so he took another sip of soda. "What would I do without
sugar and caffeine?" he mumbled to himself. Frank realized that he should probably stop the car as he noticed his hands
begin to shake, but he continued anyway. Rounding a corner, he realized that he was having trouble focusing on the
road. He tried to blink away the blurriness and shook his head, but things did not change. In an instant, the car slipped
off the road and hit a tree. "What was that?" exclaimed Frank to the night air. He quickly got out of the car and checked
himself out. Other than the shock of the accident, Frank seemed to be okay. He pulled out his cell phone and called his
wife, Stacey, to come pick him up. He then called to report the accident to the police and his insurance agent. His wife
arrived about an hour later and looked very concerned when she saw Frank sitting in the police car. "Why aren't you
going to the hospital?" screamed Stacey. "Were you drinking again?" "I'm fine, and no I wasn't drinking. Check with
Sergeant Eversman if you do not believe me. I lost focus; it has been a long day and my vision is a little off. This is too
much stress. Please, I just want to go home." The emergency staff checked him out and recommended he go to the
hospital for evaluation but Frank declined. They drove home, but Stacey continued to badger Frank about going to the
hospital.

Answers

Answer:

Frank might have been an alcoholic.

Explanation:

Because his wife,Stacey,asked him if he had been drinking and he also didnt want to go to the hospital for evaluation.

Answer:

i think that the higher the body temperature the higher the cellular respiration

Explanation:

The graph indicates the relationship between body temperature and cellular respiration. As the body temperature increases, more ATP is produced, but after a certain temperature, there is no cellular respiration.

What is cellular respiration?

In cellular respiration, the cell breaks down glucose and forms ATP. Glucose is broken down by glycolysis, the Krebs cycle, the electron transport chain, and finally ATP is formed.

In the graph, it is shown that an increase in body temperature is related to an increase in ATP molecule production. ATP molecule production is nearly zero at 80 degrees body temperature. As the temperature increases to 100 degrees, ATP production increases to nearly 50.

After 100 degrees, the body temperature rises, but there is a decrease in ATP production. After 100 degrees, the enzymes required for cellular respiration don't work. Hence, a decline in ATP is seen.

Hence, after a certain temperature, the enzymes involved in cellular respiration don't function as their structure changes.

Why to label fertilizer?

Labeling of fertilizer is to show the content of major nutrients.  They are usually labeled with three numbers i.e.,  N-P-K label, i.e., Nitrogen-Phosphorous-potassium label , such as, 0-15-15. the first number is the percentage of nitrogen, second is for phosphorus and third is for potassium.

Thus, here as per the marking, the quantity of the nutrients are: nitrogen 70 pounds, phosphorous 15 pounds and potassium 15 pounds.

Atoms with full valence electron shells are chemically stable. Most noble gases have eight valence electrons. So, one model for chemical bonding is the octet rule. This states that atoms will _________ or __________ electrons in order to reach the more stable arrangement of eight electrons in their valence shells. A) lose, gain B) conduct, share C) transfer, share D) conduct, transfer

Answers

Answer:

A - Gain or Lose

Explanation:

Atoms with full valency electron shell are usually very stable. Most noble gases with full valency shell are usually very stable . The valency electron are fully occupied(8) for all noble gases this is what makes them hard to react with other element.

During chemical bonding elements strife to attain the octet rule. The octet rule is to have a full valency electron through bonding . When this atom bond they either transfer electron or share electrons.

The case of transferring electrons forms an ionic bonding. One atom gain electrons while the other lose electrons during ionic bonding. One atom form cation while the other forms anions.

For covalent bonding  atoms are shared to attain the octet rule. This kind of bonding exist between a non metal and another non metals
