The pH scale measures the acidity of a substance. It is a negative logarithmic scale. A pH of 3 has a hydrogen ion concentration (which is responsible for acidity) ten times greater than a pH of 4. How many times greater is the hydrogen ion concentration of a pH 2 solution than a pH 6 solution?
Answer:
The correct answer is: a pH 2 solution has a 10000 times greater hydrogen ion concentration than a pH 6 solution.
Explanation:
The pH scale is a measurement used to describe the acidity of a solution, and this acidity is given by the concentration of H+ (hydrogen ion) in said substance. A solution with a greater concentration of H+, is more acid than a solution with a smaller concentration of H+ and, therefore, has a lower pH. Given that the pH scale is a negative logarithmic scale, a solution with a pH of 3 has a ten times greater H+ concentration than a solution with a pH of 4.
A pH 2 solution has 10 times more H+ ion concentration than a pH 3 solution, 100 times more H+ ion concentration than a pH 4 solution, 1000 times more H+ ion concentration than a pH 5 solution, and 10000 times more H+ ion concentration than a pH 6 solution.

How does H. pylori help maintain the homeostasis of the human body?
Answer:
H. pylori (Helicobacter pylori) is a bacteria that maintains homeostasis of the human body by establishing chronic infection from ulcers and gastritis and using the method of autophagy to cleanse the body of damaged cells. H. pylori also contributes to the workings of the immune defense system.
here is a scale of a fountain at a museum. the scale is 1:30. how many boulders are in the real fountain
Answer: 9
Explanation:
When we do a change in scale for a model of something, like a building, all the parts of the building suffer from this change of scale.
Then, the intrinsic properties (like the number of rooms and that) does not change. This means that the number of boulders that we see in the scale will be the same that the number of boulders in the real fountain:
So, if in the scale of the fountain we can see 9 rocks, in the real fountain there also are 9 rocks, just the rocks in the real fountain are larger.

(01.01 MC)Cryptozoology is a field of study aimed at proving the existence of mystery animals such as Bigfoot and the Loch Ness monster. Why is cryptozoology not considered a true science?
Answer:
This is because it is not based on scientific evidences,but rather on hypothesis from unverified information and ear says.
Explanation:
The branch of Zoology which is called pseudoscience because of lack of concrete evidences is called Crytpozoology.
it was designed for the study of set of animals in which scientific evidences for the existence is lacking.However,hypothesis based on oral stories,unreliable description by purported eye witness. non factual physical evidences and ear says are used to judge the existence.
Blancou in 1959 first coined the word.But the actual mention in scientific field was in 1965 by Bernard Heuvelmans .
Bigfots ,Chupacabra are examples of animals that cryptozoology has been used to give account of.

Explanation:
Hey, there!!
The teacher is surely describing about kingdom Plantae. Plants and animals posses some similar characteristics such as eukaryotic, multicellular, in the above descriptions. BUT;
The reason for above answer is,
Plants only produce food by themselves in presence of sunlight and chlorophyll. So, they are termed as autotrophic in nature.Similarly, plants cell only posses cellwall made up of cellulose.Hope it helps....

The famous scientist Albert Einstein sometimes used "thought experiments" such as imagining himself chasing a beam of light or riding in an elevator in free-fall. These thought experiments, which would not be possible to conduct physically, helped him challenge current scientific thinking and develop his theories of gravity and of special relativity.
Answer:
This is in order: select equipment, avoid errors, sample size, statistical analysis, hypothesis, and revised.
Explanation:
The thought experiments of Albert Einstein helped him to challenge the current scientific thinking of his time and develop his theories of gravity and of special relativity. This statement is true.
What are thought experiments?Though experiments are mental tools utilized by mang scientists, philosophers, and thinkers. They use these experiments to test theories and ideas that would not be possible in the real world.
A thought experiment encourages the skill of logical thinking, speculation, and analysis. An entire scenario and constructed and played out in the mind. The paradigms were kept the same as the real world so that the results could be related to the real world too.
This kind of experiment help to analyze the ideas that are beyond our comfort zone by making us take up the questions that we would have thought impossible to be solved.
Therefore, this mental tool was used by Albert Einstein to challenge the current scientific thinking of his time and develop his theories of gravity and of special relativity. This statement is true.

what is the color of the sky?
Answer:
the color of the sky is actually violet
Explanation:
The human eye doesn't see individual wavelengths. Instead, the retinas of our eyes have three types of color sensitive cells known as cones. One type is most sensitive to red wavelengths, while the other two are most sensitive to green and blue wavelengths. When we look at something and the light strikes our retina, the strength of signal from each type of cone allows our brains to determine the colors we see. These colors roughly correspond to the actual wavelengths we see, but there are subtle differences. While each type of cone has its peak sensitivity at red, green, or blue, they also detect light of other colors. Light with "blue" wavelengths stimulate blue cones the most, but they also stimulate red and green just a little bit. If it really was blue light that was scattered most, then we'd see the sky as a slightly greenish blue.

Is a robot an open, closed, or isolated system?
EXPLAIN WHY.
Answer:
Closed system.
Explanation:
Robot is an closed system because there is no transfer of mass but transfer of energy occurs from robot to its surrounding. According to the definition of closed system, closed system is a type of system in which there is only transfer of energy occurs while in open system both mass and energy can be transferred from the system to their surrounding. So no mass transferred from the robot only energy in the form of mechanical energy is transferred.

which of the following statements are true regarding active transport and facilitated diffusion (choose two answers) a) Active transport utilizes channel proteins and facilitated diffusion utilizes carrier proteins b) Both processes require the use of membrane proteins c) Both processes require the input of energy (ATP) d) Active transport moves substances against the concentration gradient and facilitated diffusion moves substances along the concentration gradient
Answer: B and D
Explanation: We can break down why the correct answers are choices B and D by understanding why A and C are incorrect.
Option A states that active transport utilizes channel proteins, and facilitated diffusion utilizes carrier proteins. This is incorrect. Active transport involves carrier proteins, and facilitated diffusion involves channel proteins. Carrier proteins are different from channel proteins in that, while channel proteins can only facilitate the passive diffusion of ions into or out of the cell along their concentration gradient, carrier proteins can also use ATP to move ions in or out of the cell against their concentration gradient.
This brings us to why option C is also incorrect. Option C states that both processes require the input of energy in the form of ATP. While active transport requires the use of ATP to transport ions with or against their concentration gradient, facilitated diffusion does not. This is easily remembered when we consider that active transport is called *active* transport because the cell is *actively* using energy to transport ions.
Hope this helped.
Answer: Choice B
Active transport moves substances against the concentration gradient and facilitated diffusion moves substances along the concentration gradient.
Choice D
Both processes require the use of membrane proteins.
Explanation: B- Active transport is active because it requires ATP in order to go against the gradient and facilitated diffusion is a type of passive transport that goes with or along the gradient without the use of ATP.
D- Active transport utilizes carrier proteins on the cell membrane and facilitated diffusion can utilize either channel or carrier proteins on the cell membrane.

What is an analogy of protein synthesis
Answer:
Ribosomes and tRNA
The ribosome will 'read' the mRNA and insert the appropriate amino acids. An
amino acid is a unit used to build up a protein , like a piece of timber used to build
up a house. There are 20 amino acids that cells can use, and different
combinations of these amino acids can make different proteins .
The analogy for protein synthesis or translation is building a house. In this process, DNA acts as an architect which plans for the whole house.
What is Translation?Translation is the process in which the ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins after the process of transcription of the DNA molecule to mRNA (messenger RNA) in the cell's nucleus. The entire process of translation is called as gene expression.
Building a house could be good analogy for the process of protein synthesis. Here, the DNA would be the architect, who has the plans for construction of the whole house. The DNA is changed into mRNA, which is like the copy of the blueprint that is given to the general contractor.

When you go to make yourself a sandwich, you notice that the bread has mold on it. Yuck. You decide to find out which brand of bread lasts the longest without molding. You buy 8 brands of bread and leave them on the counter. You record how long it takes for mold to form.

What is the DEPENDENT variable in this experiment? *
Your answer
What are the CONSTANTS in this experiment? *
This is for a Grade :,
Answer: Independent variable - brands of bread; dependent variable - how long it takes for mold to form; constant - bread that's not on the counter but in the fridge (or wherever it's supposed to be) instead
Explanation:
The dependent variable is the one that DEPENDS on what will happen. How long it will take for mold to form DEPENDS on the brand of bread.
The thing that is being "depended on" is the independent variable so that would be the brands of the breads.
The constant is the part of the experiment that always stays the same. Here, we aren't really given a constant so we can assume it would be the bread that's in its original position (in the fridge), untouched, so you can compare it with the other experiments (breads on the counter).
Hope this helps!
