Answer:
D. Pool temperature
Explanation:
The dependent variable in an experiment is the variable that is measured or responds to another variable called the independent variable. The outcome of the dependent variable is dependent on the independent variable.
In this computer model, the engineers compare which of several pool designs require the least amount of energy to be heated. The TEMPERATURE at which each pool design is heated is dependent on the type of pool design used. Hence, POOL TEMPERATURE is the dependent variable. It is the variable being measured in response to the type of pool design used.

What is ABO Blood Groupings?A system which is used to group human blood into different types that is based on the presence or absence of certain markers on the surface of red blood cells. The four main blood types are A, B, O and AB. The ABO blood group system is used to match the blood types of the donor and the person receiving the transfusion.
People with O blood group can donate blood to anyone and are called universal donors. People with blood type AB can accept blood from all donors and are called universal recipients. People with type A or B can receive matching blood or type O blood.Blood group A has A antigens on red blood cells, with anti-B antibodies in the plasma.
Blood group B has B antigens with anti-A antibodies in the plasma
Blood group O has no antigens, but has both anti-A and anti-B antibodies in the plasma
Blood group AB has both A and B antigens, but no antibodies
Thus, a person with type AB blood has anti-A and anti-B RBC antigens. So, the correct option is (B).

A) Which amino acid residue's backbone forms a hydrogen bond with the backbone of the seventh(7th) residue?
B) which of the following peptide segments is most likely to be part of a stable alpha helix at physiological pH?
A) -Lys-Lys-Ala-Arg-Ser-
B) -Gly-Arg-Lys-His-Gly-
C) -Pro-Leu-Thr-Pro-Trp-
D) -Gly-Gly-Gly-Ala-Gly-
E) -Glu-Glu-Glu-Glu-Glu-
F) -Glu-Leu-Ala-Lys-Phe-
G) -Tyr-Trp-Phe-Val-IIe-
Answer:
The correct answers are "amino acid3" and option F) "-Glu-Leu-Ala-Lys-Phe-"
Explanation:
The alpha helix is one the most common secondary structures of proteins, characterized by seven residue repeating units that alternate hydrophobic and hydrophilic residues. This sequence match with the peptide segment "-Glu-Leu-Ala-Lys-Phe-", where glutamic acid (Glu) is hydrophilic, leucine (Leu) is hydrophobic; and it does not contain amino acids that disrupt alpha helix such as proline and glycine. The alpha helix structure is stabilized by hydrogen bonds within the residue's backbone, one of them stablished between the third and the seventh amino acid residues.
Describe how replacing diesel/petrol fueled vehicle to electric-operated vehicles may change the environment
Answer:
By reducing the amount of carbon dioxide emissions contributing to global warming
Explanation:
Global warming is an arising problem caused by the emission of gases called GREENHOUSE GASES into the Earth's atmosphere. The greenhouse gases include Carbon dioxide, methane etc.
Carbon dioxide as the principal cause of global warming is emitted when fossil fuels like petroleum products like diesel or petrol are burned. Therefore, the use of automobiles like cars releases CO2 into the atmosphere. Therefore, replacing diesel/petrol fueled vehicle to electric-operated vehicles may change the environment by reducing the amount of greenhouse gases (CO2) emitted into the atmosphere, ultimately helping to reduce global warming.
Corals form symbiotic relationships with microscopic photosynthetic algae that live in their cells and give the corals their distinct colors. The relationship is an example of mutualism, in which both species benefit. Predict how each organism in this relationship could benefit the other.
Answer and Explanation:
Corals are translucid or white, but they look brightly colored because they host symbionts with colorful photosynthetic pigments . They can host different organisms that live on and among them, giving place to an amazing ecosystem.
One of these organisms is the photosynthetic unicellular microalgae, called zooxanteles, that are colorful and provide nutrients to the coral.
Corals provide shelter and protection to the algae, while algae provide nitrogenated nutrients, sugars, and color to the corals. Algae can store nitrogen in their tissues as nitrogen-rich crystals, which are constantly provided to corals.
This symbiotic relation allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as the tropical clear waters.
When changes in radiation, temperature, or salinity in water occur, corals react to these changes losing these algae and becoming translucid again.
During the cell cycle, the cell must pass through several checkpoints that confirm that the cell is ready to progress to the next phase of the cycle. If the requirements of one phase have not been met, the cell cannot proceed to the next phase. These checkpoints help control the rate of cell division. If a mutation disables one of these checkpoints, what is most likely to happen
Answer:
The correct answer would be - Cells begin dividing faster, leading to cancer.
Explanation:
In the process of the cell cycle, there are several checkpoints that ensures that the cell is all set to move to next phase, the cell that not match the requirements cell have not move to next phase.
These checkpoints control the rate of cell proliferation or division and if a dividing cell fails to pass through any checkpoints due to the mutation, it is most likely divide uncontrollably and lead to cancerous or tumor cell.
Thus, the correct answer is - Cells begin dividing faster, leading to cancer.

The pH of blood is not affected by: ______a. hyperventilation.b. the pKa of acetic acid or acetate. c. consuming large amounts of sodium bicarbonate.d. fasting and starvation.
Answer:
The correct option is the pKa of acetic acid or acetate.
Explanation:
The blood pH is affected by hyperventilation since it triggers hypercapnia, an increase in metabolic acids and therefore a decrease in blood pH.
Excessive consumption of sodium bicarbonate, since this would alkalize the blood, and finally, prolonged fasting or excessive hunger generates the degradation of fat sources, with the consequent formation of ketone bodies as a product, and therefore entering a metabolic acidosis.

Explanation:
Juan, a biologist, notices that a particular group of hummingbirds leaves during the colder winter months and returns during the warmer spring months. Juan hypothesizes that the birds fly south to locations with warmer weather and blooming flowers during the winter months. Which procedure should Juan use to test his hypothesis?
This question is incomplete because the options are missing; here is the missing section:
Which procedure should Juan use to test his hypothesis?
A. Survey northern and southern residents about the birds in their areas.
B. Observe the direction the birds fly when they depart in the winter.
C. Tag the hummingbirds with transmitters and track their movement.
D. Set up observation posts in the south to verify the time of year that birds arrive.
The answer to this question is C. Tag the hummingbirds with transmitters and track their movement.
Explanation:
To prove or disprove his hypothesis about birds Juan needs to test the direction hummingbirds fly to during the winter because only in this way he can know if the birds fly to the South as he thinks or they go to a different place. Moreover, this can better be tested through precise instruments such as trackers because these will register the movement of birds and clearly show if they are going to the South. Moreover, others such as the opinions of residents or the initial direction when birds migrate might be inaccurate.
There is a theory that gravity Eould pull galaxies back together, causing a reverse big bang Which observation makes this theory less likely than the idea that the universe may continue to expand? Background radiation is present, Galaxies exist outside of the Milky Way. The expansion of the universe is accelerating Gas giants form farther from the Sun, where temperatures are cooler.
Answer:
Explanation:
The correct answer is derived from Hubble's observation that galaxies that are further away from the sun are moving away from our sun at a rate that is greater than those that are close by.
This observation suggests that our universe is expanding.
Now which choice best fits this observation? I don't know that this answer is correct, but it might be the closest choice. Galaxies exist outside the Milky Way, but that answer does not take into account their motion which is a necessary part of the theory.
Answer: The expansion of the universe is accelerating

What characteristics of a northwest coniferous forest biome make it an appropriate home for banana slugs
Answer:
It is a humid place that helps them to hide in places according to their corporal environment. They are scavengers on the forest floor that feed on small animals (already dead), but most of them are decomposers, feeding on debris.
Explanation:
The characteristics of a northwest coniferous forest biome that makes it an appropriate home for banana slugs is due to the fact that it's a humid place and this helps the banana slugs hide from their enemies.
The northern coniferous forest biome can be found below the tundra and it extends across Canada. It's also referred to as the boreal forest. It has a warmer and longer growing season.Some examples of animals that can be found in the northwest coniferous forest biome include moose, red fox, owl, snowshoe hare, etc.It should be noted that due to the fact that the northwest coniferous forest biome is humid, banana slugs protect themselves. They typically stay moist in order to stay alive. They also produce mucus which is used for self-defense.In conclusion, banana slugs hide in damp places in order to retain their body moisture.
