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.

Which atmospheric condition will increase the amount of air pollution close to the surface of the Earth?
- Prevailing winds
- Dry deposition
- Thermal inversion
- Photochemical smog
The atmospheric condition will increase the amount of air pollution close to the surface of the Earth is Prevailing winds.
Prevailing winds in the ecosystem blows dust and other particles from
different areas into the air thereby making the air dusty and unsafe for
breathing by organisms.
Prevailing winds has its importance in helping to determine the amount of rainfall an area will receive during a period of time.

Answer:
Some existing methods for controlling Zika-carrying mosquitoes are not effective and may even be counter-productive.
Explanation:
It was found that while biological interventions did appear to reduce numbers of disease-carrying insects more than chemical controls, the quality of the evidence was often poor.
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.

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.

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.

A bacterial cell usually contains a single loop of DNA that is located in the cytoplasm of the cell and is not surrounded by a nuclear membrane. Some bacteria have additional loops of DNA called plasmids. Plasmids can be used for genetic engineering because DNA from other organisms can be spliced into a plasmid loop. For example, scientists in the late 20th century discovered a way to insert the portion of human DNA that codes for the protein insulin into plasmid E. coli bacteria. Which statement best explains why these genetically modified bacteria have been useful to society?
A. Human diabetics are now more resistant to bacteria
B. The bacteria are resistant to human diabetics
C. The bacteria can now make their own insulin
D. the bacteria are used to produce cheap insulin.
Answer: A is the correct answer.
because for the treatment of one type of diabetes insulin should be provided but isolation of insulin and production is so costly.
but as DNA recombination has developed we can use bacterial replication system to produce insulin. they replicate very fast so large amount of insulin will be produced and then it can isolated.
but we also know that insulin of bacteria needs some modification before it can be used in human.

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.
