Which of the following is a characteristic of hydrologic fracturing?
A. Large amounts of water force open cracks in rocks
B. Removal of topsoil to reach water supply
C. Transportation of coal via waterways
D. Use of machinery underground to mine coal
Answer:
A. Large amounts of water force open cracks in rocks
Explanation:
Hydraulic fracturing, or fracking, is a drilling method used to extract petroleum (oil) or natural gas from deep in the Earth. In the fracking process, cracks in and below the Earth's surface are opened and widened by injecting water, chemicals, and sand at high pressure.
A is basically explaining this the same way. Forcing cracks in the ground with liquids.

Two of the four main classes of organic compounds are proteins and nucleic acids. What is the relationship between proteins and nucleic acids?
Answer:
Proteins are important structural and functional biomolecules that are a major part of every cell in your body. There are 2 nucleic acids -- DNA and RNA. Your cells make proteins by following the instructions encoded in your DNA, which is genetic material and a type of nucleic acid.

PLEASE HELP WITH THIS ONE QUESTION
Answer:
perfect cube shape
Explanation:
the shape of a cell is perfectly cube- shape then its volume must be calculated with an equation:
Height×Width×number of sides and number of boxes
Surface= area of volume ratio is calculated with an equation
Area /volume
if a cell has large surface area to volume into ratio means it has greater exposure to the environment.It means that flow of nutrients and gases move freely in the small cell compared to large cell.

A 100-pound bag of fertilizer is marked 0-15-15. How many pounds of nitrogen,
available phosphate, and potassium are there in the bag?
Fertilizers are the chemical element for improvement of productivity of plants. Here, 0-15-15 shows nitrogen 70 pounds, phosphorous 15 pounds and potassium 15 pounds.
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.

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.

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.
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.

Which object is hotter in terms of its kinetic energy: the cup of coffee or the iceberg? Explain the reason for your answer in terms of your understanding of the kinetic molecular theory of matter.
Answer:
red-hot iron bar
Explanation:
An iceberg could even contain more heat energy than a cup of coffee or a red-hot iron bar. That's because its bigger and contains so many more molecules, each of which has some heat energy. The coffee and the iron bar are hotter (have a higher temperature), but the iceberg holds more heat because it's bigger.

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
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
Answer:
Explanation:A: gain or lose
What is the biology
Answer:
science that studies living things
Explanation:
it includes plants and animals so basically anything that has life
Answer:
Biology is the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behaviour, origin, and distribution.
Explanation: Branches of biology are different topics related to biology; for example the 3 major branches of biology are:
Botany, also called plant science, plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field
Zoology is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems.
Microbiology is the study of microorganisms, those being unicellular, multicellular, or acellular. Microbiology encompasses numerous sub-disciplines including virology, parasitology, mycology and bacteriology.
