A person has a high fever of 105°F. State one effect that this high fever would likely have
on enzyme activity.
Answer:
The enzyme will change shape/denature, and stop activity
Explanation:
A person has a high fever of 105F. an effect that such a high fever would likely have on enzymatic activity is denaturing enzymes in the nervous system, possibly causing epileptic seizures.
What is the reason of high fever ?High fever (above 100F) is very dangerous for humans and can be fatal. One of the causes of this problem is the fact that high temperature modifies enzymes in the central nervous system which inducing the modification of the amino acid sequence of the enzymes.
With this given information, it is concluded that a person has a high fever of 105F. an effect that such a high fever would likely have on enzymatic activity is denaturing enzymes in the nervous system, possibly causing epileptic seizures.
Therefore, A person has a high fever of 105F. an effect that such a high fever would likely have on enzymatic activity is denaturing enzymes in the nervous system, possibly causing epileptic seizures.

how does the pleura help with breathing?
question 2) what is the purpose of the diaphragm?
Biology!
Answer:
1.The pleural cavity aids optimal functioning of the lugs during breathing. It transmits movements of the chest wall to the lungs, particularly during heavy breathing. The closely approved chest wall transmits pressures to the visceral pleural surface and hence to the lung (10-19.
2.The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarge.

A structural change in the alpha-factor of Saccharomyces (a type of yeast) is shown to render the molecule defective. What effect would this mutation have on the reproductive behavior for this yeast cell species? Justify your claim by discussing cell signaling and response events.
The ability of the yeast cell to divide and reproduce is lost if the alpha receptor's structure is damaged. Structure loss leads to function loss.
What is alpha factor in yeast?The alpha cells of Saccharomyces cerevisiae release alpha-Factor, a 13-amino-acid pheromone, which binds to Ste2p, a seven-transmembrane, G-protein-coupled receptor, to trigger a signal transduction pathway necessary for mating and conjugation.
Yeast has two mating types, MATa and MAT. A yeast cell undergoes physiological changes when triggered by pheromone from an opposing mating type cell. These include alterations in the expression of 200 genes (approximately 3% of the genome), pause in the G1 phase of the cell cycle, directed growth toward the mating partner, and the fusion of the mating partners' plasma membranes, followed by the fusion of their nuclei. Process takes 4 h.

One limitation of Armando’s model is that all the water enters the model from one source: the water tank. Explain why this is a limitation of the model.
Answer:
No other source of water is used for this model.
Explanation:
All the water enters the Armando’s model from only one source and that source is the water tank. This is considered as a limitation of the Armando’s model because only water tank source is used in this model and no other source is compatible with this model so that's why this water source is considered as limitation of this Armando’s model.

A) 2,000 kilometers
B) 4,600 kilometers
C) 1.5 million kilometers
D) millions of kilometers
Answer:
D) millions of kilometers
Explanation:
The sun's corona extends million of kilometers into space from the sun outward.
The corona of the sun is one of the layers of the sun with blistering plasma extending into the space. It extends several million of kilometers away into the solar system. This layer has a whooping temperature of about 2-5million degree Celsius.
It is the light and energy conveyed through the corona that furnishes all the planets with radiant energy.

If a limiting nutrient is supplied to the producer in the diagram above, what effect could it have on the birds?
Answer: The producers are the bluegrass. Adding a limiting nutrient to the grass would increase the amount of primary productivity. The result would be an increased amount of biomass at the producer level, and increasing biomass and available energy at each successive level. The number of birds could increase, because there would be more for them to eat.

The following are sources of Earth's internal heat energy EXCEPT
a. Decay of radioactive isotopes
b. Primordial heat
c. pressure from overlying layers
d. Sun’s energy
The sun's energy is not a source of Earth's internal heat. So the correct option is D.
What is the earth's internal heat?
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move may reveal a lot to scientists about the composition of the Earth.
The solidity, liquidity, or partial solidity of these materials can also be determined using seismic data. Laboratory results, meanwhile, show what pressures and temperatures the materials inside the Earth should melt at.
The temperature of the Earth's core is thought to be between 5,000 and 7,000 degrees Celsius based on this information. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.
Although the amount of heat created inside the Earth is immense, the amount of heat energy received from the sun is around 5,000 times stronger. The weather is influenced by the sun's heat, which ultimately leads to erosion. It is so paradoxical that although the heat of the Earth creates mountains, the energy of the sun gradually breaks them down again.
Therefore the correct option is D.
