What does ATP mean?
ATP stands for adenosine triphosphate. It is a molecule found in the cells of living organisms. It is said to be very important because it transports the energy necessary for all cellular metabolic activities. ... Without ATP, various metabolic activities in the human body cannot take place.
The main function of ATP?
ATP functions as the energy currency for cells. It allows the cell to store energy briefly and transport it within the cell to support endergonic chemical reactions. The structure of ATP is that of an RNA nucleotide with three phosphates attached.

2. Consider a well-trained 130-pound female marathon runner, Jordan. Jordan has just loaded up on a carbohydrate meal and has the maximum amount of stored glycogen (6.8 grams of glycogen per pound of body weight). (10pts) a. How many grams of glycogen is Jordan storing in her body? Show your calculations
Answer:
884 grams of glycogen
Explanation:
Jordan's body weight = 130 pounds
Rate of storage of glycogen per pound of bodyweight = 6.8 grams
Total grams of glycogen that Jordan can store at maximum capacity:
bodyweight x rate of storage
= 130 x 6.8 grams
= 884 grams
Hence, Jordan is storing 884 grams of glycogen in her body.

Discuss the mechanisms of speciation
Answer:
There are four major variants of speciation: allopatric, peripatric, parapatric, and sympatric. Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

4)The flu, also known as the influenza virus, is diagnosed year-round in the United States. Fall and winter seasons are when the greatest impact is usually seen and, therefore, is considered the "flu season." Influenza activity has a period of greatest activity between December and February, but the activity can last until May.
Every year at the beginning of the fall season, people are encouraged to get a flu shot.
CDC data on influenza vaccine:
• 116 million doses of influenza vaccines have been distributed.
CDC
(Centers for Disease Control and Prevention) recommends that all persons 6 months and older receive the influenza vaccine at the end of October.
• Influenza vaccination offers important benefits

A flu is a common viral infection that can be deadly if not treated on time. This is caused by the influenza virus. The common symptoms include fever, chills, muscle aches, cough, fatigue and runny nose.
What is Flu?
Flu is a viral infection caused by the Influenza virus. This is a communicable disease. The flu virus attacks the lungs, nose and throat. The respiratory system is weakened. People who have a weak immune system or have a chronic disease are more prone to flu infection.

This misdiagnosis can complicate the situation which makes the treatment of infection difficult.
Flu season is an annually recurring period. The season occurs when its half cold in each hemisphere.
Flu is a communicable disease which lasts for approximately two-three days. During this period, an affected person is advised to stay away from other healthy people which interferes with the business and government work. Also, the residents are not advised to go in public which affects their access to certain resources.

Which of the following is NOT a reaction of the
parasympathetic nervous system?
A. Decreased respiration
B. Decreased heart rate
C. Increased blood flow to digestive tract
D. Decreased saliva production
Answer:
D
Explanation:
D, or decreased saliva production is not a reaction of the parasympathetic nervous system (PSNS) since the PSNS actually increases/causes salivation which helps you digest your food.
As a tip, I usually associate the PSNS with a state of rest/restful conditions, as opposed to the sympathetic nervous system which is the opposite and is associated with stress and high-pressure conditions (like fight or flight).

Analyze the example of gene expression of the bacteria below:
In this example, what would cause the genes to be expressed?
An operon that is turned off
Polymerase being blocked from bonding to the DNA
The presence of an active repressor
A repressor that is unable to bond to the DNA
Answer:
This question is incomplete as it lacks the image. The answer is:
D. A repressor that is unable to bond to the DNA
Explanation:
The expression of a gene in a prokaryote like bacteria is regulated at the transcription level. Normally, a Gene is expressed by first undergoing transcription from DNA to mRNA with the aid of an enzyme called RNA polymerase.
However, a protein called REGULATORY PROTEIN which serves as a repressor inhibits the binding of RNA polymerase to the DNA sequence. According to this question, the gene will only be expressed if the repressor is unable to bond to the DNA, hence, not being able to prevent transcription.

The process when rocks break into smaller pieces due to exposure to
natural elements is called
Answer:
Weathering.
Explanation:
Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.
The process when rocks break into smaller pieces due to exposure to natural elements is called weathering.
What is weathering?Weathering can occur through physical, chemical, or biological means.
Physical weathering involves the mechanical breakdown of rocks into smaller fragments without changing their chemical composition. Chemical weathering, on the other hand, involves the breakdown of rocks through chemical reactions, resulting in the formation of new minerals. Biological weathering is caused by living organisms, such as plants and animals, that can physically break down rocks or release chemicals that can alter the rocks' composition.
