Describe five of these properties and provide an example of each: Hydrogen bonding, cohesion and adhesion, surface tension, heat of vaporization, specific heat, density, and universal solvent

Answers

Answer 1

Answer:

Explanation:

Hydrogen bond is an intermolecular force of attraction, it occur between a proton in a molecule and an electronegative atom in the another. It is weak bond and can be found in water molecule.

Cohesion is force of attraction thst occur when molecules are attracted to other molecules of the same type

this can be found in hydrogen bonding.

Adhesion occur when molecules are attracted to different substances. It can be founf in water when reaction with other substance

A universe solvent is a substance that is used to dissolves many substance. Example is water it can be used in dissolving many substance.

Surface tension is the ability of a liquid surfaces to reduce into the minimum surface area. It allows some insect that are less dense to float in water

Head of vapourization is the amount of heat required to change a liquid into a vapor. Heat to convert water into vapour

Answer 2

Answer:

pH

Explanation:

"The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution. The letters pH stand for 'power of hydrogen' and numerical value for pH is just the negative of the power of 10 of the molar concentration of H+ ions."

Examine the statement. A scientific theory can become a scientific law, but a scientific law cannot become a scientific theory. If the statement is true, select “True.” If it is false, select the option that is true 1.) True 2.) A scientific theory can become a scientific law, and a scientific law can become a scientific theory. 3.) A scientific law can become a scientific theory, but a scientific theory cannot become a scientific law. 4.) A scientific theory cannot become a scientific law, and a scientific law cannot become a scientific theory.

Answers

Answer:

It's true.

Explanation:

In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research.

When the scientists test the idea, they develop a theory by following a set of logical steps. A theory becomes a scientific law once it has been rigorously examined and accepted. Thus, option A is correct.

What A scientific theory can become a scientific law?

One prevalent fallacy is the idea that hypotheses eventually become laws. Despite the number of supporting examples, hypotheses do not actually become laws after repeated testing.

Scientific laws, like theories, explain occurrences that the scientific community has determined to be verifiably true. In general, laws explain what will occur in a specific circumstance and are proven by a mathematical equation, whereas theories explain how the phenomenon occurs.

Therefore, A testable explanation of a natural event is what constitutes a scientific hypothesis. The concept of gravity, for instance, explains why an apple always falls to the ground when.

While performing an experiment, it is important to:
a. change the control setup
b. test many different variables at the same time
c. reach a conclusion
d. record observations and measurements

Answers

Answer:

D

Explanation:

While performing an experiment, it is important to record observations and measurements, as in Option d. Option d is correct regarding the facts of the experiments, while the others are wrong.

What is an experiment?

The experiment is carried out to observe the hypothesis, and in this process, a control set-up is taken whose value or result is already known, and the variables are taken and compared with the control. The controls set should never change in the experiment because the variables are tested with reference to them, and the measurements and observations of the experiment should be taken into consideration to prove the hypothesis. All the variables should not be tested at once because if this is done, it would introduce error into the experiment, and not all the experiments are done to get the conclusion.

Hence, while performing an experiment, it is important to record observations and measurements, as in Option d.

Evaluate this statement: Gene flow increases the genetic divergence of populations. Evaluate this statement: Gene flow increases the genetic divergence of populations. This statement is true. This statement is false. Gene flow is not able to influence the genetic divergence of populations. This statement is false. Gene flow reduces the divergence of populations. This statement is false. Gene flow increases the number of genes in populations.

Answers

The correct answer is C. This statement is false. Gene flow reduces the divergence of populations.

Explanation:

In biology and related areas, genetic divergence occurs if populations with a common ancestor develop unique traits, which are the result of genetic changes over time. On the other hand, gene flow occurs when traits including genes flow from one population to another, usually because the populations are in contact. In this context, gene flow reduces divergence because if genetic material flows between populations is less likely each population can develop unique traits, instead the populations involved will have similar traits after some time.

The correct answer is C. This statement is false. Gene flow reduces the divergence of populations.

The following information should be considered;

In terms of biology and related areas, genetic divergence arise at the time when the populations are with a common ancestor that created unique traits, due to this there are genetic changes over time. While gene flow arise at the time when traits involved genes flow from one population to another, normally due to the populations are in contact. In this given situaton, gene flow reduces divergence since genetic material flows between populations is less likely every population can create unique traits, rather the populations involved will have similar traits.

A. cancer cells grow in a more regulated fashion.

B. cancer cells do not need to adhere to a substratum to grow.

C. nutrient requirements for cancer cells are precisely defined.

D. cancer cells are better models for demonstrating what happens in an intact organism

Answer:

B.

Explanation:

Cancer cells are easier to culture in comparison to normal cells because cancer cells do not need to adhere to a substratum to grow.

As cancer cells are uncontrolled growth of cells and they do not require any substratum to grow and can easily grow to a culture while a normal cell require optimal conditions to grow in a culture.

Hence, the correct option is "B".

Las plantas son productores primarios, mientras que los animales son consumidores

Explanation:

La cadena alimenticia está conformada por niveles tróficos donde la energía fluye desde los niveles basales representados por la base de la pirámide, hasta los niveles superiores (pico de la pirámide). De este modo, los organismos representan diferentes eslabones de acuerdo a su posición en la cadena alimenticia. En el primer nivel se encuentran los productores primarios como lo son, por ejemplo, las plantas y algas de ambientes terrestres y acuáticos, respectivamente, siguiendo por los consumidores primarios (por ejemplo, especies hervívoras), continuando sucesivamente por los consumidores secundarios, terciarios y cuaternarios (especies carnívoras), los cuales se encuentran en posiciones cada vez más altas de la pirámide. No obstante, es importante indicar que existen ocasiones donde los consumidores superiores (ya sea secundarios, terciarios y cuaternarios) se alimentan de especies situadas por debajo de diferentes niveles no consecutivos e incluso también de especies pertenecientes al mismo nivel trófico, con lo cual encajando en más de una categoría y dificultando su clasificación en la cadena.

What has a greater influence on protein levels? A.

Protein degradation has a greater influence because outside factors like antibiotics can cause it, and it is difficult to recover from

Answers

Answer: b

Explanation: i got the answer wrong and i’m looking at the results rn

Protein is being produced with the help of a process called translation in which mRNA gets translated to produce proteins. The translation is followed after the process of transcription of DNA to RNA.

The cause of the greater influence of protein levels has defined as follows:

The destruction of mRNA could greatly influence protein levels as mRNA is considered the source for proteins to get synthesized. This is because if mRNA gets destroyed, proteins would not have been produced at all. Thus, directly influences the levels of protein.

Thus, we can conclude that mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced. Hence, option (b) is the correct answer.

Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything

Answers

The question is incomplete,below is the complete question.

Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything?"

You tell the Clinical Nurse Specialist (CNS). As the two of you move him into the bed, you notice that his chest tube bottle is lying on its side on the gurney, with air going into it. When you point this out to the CNS, she immediately grabs the bottle and sets it upright on the floor. You see air start bubbling through the fluid right away. "That was the problem!" she says. "They lost the water seal, and air was going into his chest from the bottle. You would not believe how many times that happens on transport." When you examine Mr. B, you have trouble detecting his lung sounds on the left. Even stranger, his apical heart sound is in the wrong place - it is over toward the right side of his chest. His respiration rate and heart rate are both increased, and he is struggling to breathe. "Let's give him a little oxygen. He'll be a lot better in a half-hour," says the CNS. "Check back on him."

QUESTION - Why would accumulation of air in his pleural space cause his heart sounds to be in the wrong place?

Accumulation of air in Mr B pleural space will cause his heart sound to be heard in the wrong place because the left side is his chest is being filled up with air making the organs in his chest to to be pushed over to the right side.
