Answer:
Hydrogen bond
Explanation:
The covalent bonds between the oxygen and the hydrogen atoms result from a sharing of the electrons. This is what holds the water molecules themselves together.

Jayden is taking a test. He has to write why scientists support the theory that life began near hydrothermal vents in the ocean. Which point should he include in his answer?
A.
Hydrothermal vents were closest to ocean surface, and therefore could receive oxygen.
B.
Oceans were dry and only had water near the hydrothermal vents in the earlier ages.
C.
Even today, all life forms are first born near hydrothermal vents and they later migrate to land.
D.
Fossils of archeabacteria, which are early common ancestors, were found near hydrothermal vents.
Answer:
The answer is; D
Archaebacteria are early life forms on earth. They utilized the process of chemosynthesis to make organic molecules from inorganic molecules and for energy. The word archae means ‘ancient’ life forms. These single-celled organisms evolved around sulfur-rich environments of the hydrothermal vents.

Which letter marks the zone of inhibition?
Answer:
A. B
Explanation:
"B" as labelled in the above is the zone of inhibition.
The Zone of Inhibition is actually a test which is used to assess antimicrobial activities of a material or solution in relation to an micro-organism as a target. It is also known as Kirby-Bauer Test. It measures the antibiotic resistance and also used to inhibit microbial growth.
At the Point B, microbes can not grow in there; they are inhibited.
In the test, if bacterial strain or any other strain is susceptible to the antimicrobial agent, a zone of inhibition appears. If it shows resistance to that agent, then no zone is evidential.
why are pig/sheep hearts used to study the anatomy of the human heart?
Answer:
Pig hearts are used to study the anatomy of human hearts because they are very similar in structure, size and function to human hearts. These similarities, combined with the fact that they are much more readily available than human hearts, make them an ideal choice for research and study.

When the isotonic saline solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. Based on this information, what can be said about these two solutions?
Answer:
The new solution has a higher concentration than the isotonic saline solution
Explanation:
Here, we want to deduce what has happened in the question.
We are told that the level of the isotonic saline solution dropped because it was connected an unknown solution using a semipermeable membrane.
Since the level of the solution dropped, then it must have occurred that there has been the loss of some of the molecules of the solution.
What has occurred is the process of Osmosis
Osmosis simply involves a movement through a semipermeable membrane of solvent molecules due to the fact that the previous solution is of lower concentration than the present one.
So what we can see here is that there has been a movement due to osmosis as a result of the fact that the new solution has a higher concentration than the former one
After Pedro had breakfast, he went for a run. Identify at least three energy transformations that had to take place to allow Pedro to complete his run. Then use evidence to support the claim that energy in this system was conserved as it was transformed.
1) Chemical to mechanical (calories -> muscle contractions)
2) mechanical to mechanical (muscle -> motion)
3) mechanical to thermal (motion -> heat from the body causes sweating)
The potential energy is stored in the body chemically (via food). That potential energy is then released when the body is put in motion.

I believe that the solubility of oxygen will decrease as the temperature increase.
I believed that because as temperature increases molecules start to move faster and move farther away from each other.
Temperature can have a significant impact on the concentration of oxygen in various environments. 1) Solubility of Gases, Oxygen Dissociation, Biological Processes.
Here's a step-by-step explanation of how temperature affects oxygen concentrations:
1. Solubility of Gases: The solubility of gases, including oxygen, in a liquid like water is affected by temperature. Generally, as temperature increases, the solubility of gases decreases. This means that at higher temperatures, less oxygen can dissolve in water or any other liquid.
2. Oxygen Dissociation: In the context of the human body, temperature affects the dissociation of oxygen from hemoglobin in red blood cells. As temperature increases, the affinity between oxygen and hemoglobin decreases. This means that oxygen is more readily released from hemoglobin and made available to tissues and organs. Conversely, as temperature decreases, the affinity between oxygen and hemoglobin increases, making it more difficult for oxygen to be released.
3. Biological Processes: Temperature also affects the metabolic rates of organisms. Generally, as temperature increases, metabolic rates increase, leading to higher oxygen consumption. For example, in aquatic ecosystems, warmer water temperatures can enhance metabolic rates of aquatic organisms, leading to increased oxygen demand. Conversely, lower temperatures can slow down metabolic rates and reduce oxygen demand.
It's important to note that the specific effects of temperature on oxygen concentrations can vary depending on the system or environment being studied. Different factors such as pressure, salinity, and the presence of other substances can also influence the relationship between temperature and oxygen concentrations.

Why are carbon important to these molecules
Answer:
Hiya! ^^
Explanation:
Carbon's molecular structure allows it to form bonds with many elements, itself other carbon elements. Because of this, it can form long chain molecules, each having different properties. Carbon remains in balance with other chemical reactions in the atmosphere and water because of its stability.

If a red-eye female fly is crossed with a red-eye male fly, could they produce offspring with white eyes? Briefly explain your answer. Your answer must include a Punnett square that proves your answer.
If the red-eye parents are homozygous, no. But if the red-eye parents are heterozygous, yes.
Monohybrid crossingWe are assuming that the red-eye trait is dominant over the white-eye trait. If two red-eye parents are crossed with one another, whether they could produce white-eye offspring would depend on the zygosity level of the parents.
Assuming that red-eye is R and white-eye is r. If the two parents are homozygous red-eyed, their genotypes would be RR. Crossing the two:
RR x RR
RR RR RR RR
All the offsprings would be RR and there is a zero chance of producing a white-eye offspring.
Now, assuming that the two parents are heterozygous:
Rr x Rr
RR Rr Rr rr
Both RR and Rr are red-eyed while rr is white-eyed. The Punnet's square for the cross can be found in the attached image.
In other words, it will only be possible for the two red-eye parents to produce white-eye offspring if they are both heterozygous. Any other genotype will give a zero chance of white-eye offspring.
