Answer:
A pH scale measures how acidic or basic a substance is.
Explanation:
The pH measures the H+ concentration in a substance. The more lower the pH, the more acidic the substance, the higher the pH, the more basic the substance. It measures from 0-14, with 7 being neutral. Anything less than 7, acidic. Anything above 7, basic.
If I helped, a brainliest answer would be greatly appreciated!

Giant salvinia is an aquatic plant that floats on water and reproduces rapidly. When these plants die, decomposition by bacteria affects oxygen levels in the water. As more plants die, less oxygen is available in the water. Students observe a pond covered by giant salvinia.
(Insert a picture of some Giant Salvinia floating in a pond)
Which statement is the best prediction the students can make about the immediate future of the pond?
A) The depth of the water in the pond will increase.
B) Fish populations in the pond will begin to decrease.
C) The amount of bacteria in the pond will suddenly decrease.
D) The number of different types of plants around the pond will increase.
Answer:
B
Explanation:
I think it’s B
Answer:
B
Explanation:
There would be no oxygen, so the fish couldn't survive in that water.

Why do light-fur mice survive LESS often on dark rocks, compared to dark-fur mice?
Answer:
for a creature with a lighter fur color it is next to impossible to blend into darker colored environments compared to darker fur colored creatures
The light fur mice survive less on the dark rocks compared to the dark fur mice. The reason is the light fur mice can be easily visible by the Predator and eaten by them.
What is adaptation?An adaptation is a process in which an organism tries to adapt with the environment in order to protect itself from the predator. There are different types of adaptation seen in the animal kingdom, such as mimicry.
An example is mice fur coloration on the dark rocks. Dark rocks have dark coloration. When dark-furred mice live on this type of rock, their colour will mix with the dark colour of the rock. As a result, they can't be clearly visible to the predator's eye. Predators that are present at a distance, such as birds can't distinguish between the rock and the dark mouse's fur. This increases their chance of survival. When a light fur-colored mouse lives on the dark Rock, it can easily be differentiated by the Predator and eaten by them.
Hence, light colour fur mice survives less than the dark fur mice on the dark Rock as they can easily be seen by predators.

The amount of Cytosine plus Guanine is 40%. What would be the amount of Adenine?
Answer:
30%
Explanation:
Considering that the amount of Cytosine added to the amount of Guanine is 40%, that explains that Cytosine and Guanine each equal to 20%.
Cytosine: 20%Guanine: 20%Now, the remaining bit is 60%. Since Adenine and Thymine both equal the same, that would mean: 60/2 = 30.
Adenine: 30%Thymine: 30%Cytosine and Guanine pair together and will always be equal to one another. The same goes for Adenine and Thymine. (A=T, C=G)
Always remember that you want it to total up to 100% at the end.
why are onion cells yellow?
Answer:
I believe they are actually white but onions can be yellow when they are old or when they turn bad
Dylan wants to observe some onion cells with a microscope. He places the cells on a slide. Describe how Dylan uses the microscope so he can see the cells with a ×20 objective lens.
Answer:
See the answer below
Explanation:
After routinely cleaning the microscope and ensuring that all the parts are working fine, Dylan would have to place the slide on the stage of the microscope, switch on the light source, and adjust the diaphragm of the condenser to ensure that adequate light gets to the slide on the stage.
Thereafter, Dylan would need to turn the revolving nosepiece in order to shift to the lowest objective of the microscope assuming it is not already in place. Then, the slide on the stage is brought into focus (by viewing through the eyepiece/ocular) by using the coarse/fine adjustment knob to bring the stage up/down.
Once the slide is brought into clear focus, the revolving nosepiece is then turned to switch the x20 objective. Generally, at higher objectives, the coarse adjustment knob is rarely needed and the fine adjustment knob is solely used instead to bring the slide back into focus. Thus, Dylan can see the cells of the onion at the desired objective.

1. Friction can cause a moving object to stop.
TRUE OR FALSE
Answer:
true
Explanation:
cus over a time when the objects energy get's reduced it would be halted by friction
Friction can absolutely causes a moving object to stop (stationary). So, the answer is True.
What is Friction?
It is a type of force that tries to slow down or stop the movement of a moving object when the two surfaces are touching each other.
To stop the object, surfaces also play an important role. For example, Rough surfaces produce more friction otherwise things would be just rolling.
Therefore, friction can cause a moving object to stop.

Please answer as soon as you can
Answer:
Differences in air temperature cause movement in the air, which creates pressure.
The radiant energy from the Sun is transferred to the atmosphere, causing air movement. The air becomes less dense, so it rises.
As the air falls, it becomes more dense and cools to Earth’s surface.
The higher the latitude, the colder the climate; the lower the latitude, the hotter the climate.
At the end of meiosis ll, each of the haploid sex cells had only half the number of chromosomes as the original diploid cell. Why is this important?
Answer:
The cells at the end of meiosis II must have half the number of chromosomes because, if they didn't have, the reunion of both gametes with diploid number of chromosomes for example, in gametes would form twice the number chromosomes.

What is scaling?
Removing bark from a tree
Cutting down trees for timber
Measuring wood for harvesting timber
A survey of the number of trees in a forest
Answer:
measuring wood
Explanation:
for harvesting timber
Scaling is a survey of the number of trees in a forest. Therefore, option (D) is correct.
What is scaling?Scaling is a method of estimating the amount of wood in a tree or in a stand of trees by measuring the diameter and height of the trees. This information is used to calculate the volume of wood in the tree, which can then be used to determine the amount of timber that can be harvested from the tree or stand.
Scaling is an important part of the forestry industry, as it helps to ensure that the timber harvest is sustainable and that the forest is managed in a responsible manner. Scaling does not involve cutting down trees or removing bark from a tree.

Explanation: took the test got an A
According to the Northern Hemisphere, all the statements given are exactly true.
What is the Northern hemisphere?It is one-half of the earth that is located in the north of the equator. It has about 90 percent of the world's population and most of the world's land.
Equinox means the duration of day and night are equal in length. There are two equinoxes in a year when the sun moves across the celestial equator, which lies directly above the earth's equator. The summer solstice occurs when the earth's pole is tilted towards the sun and receives more sunlight in the northern hemisphere. Winter solstice occurs when the earth's north pole is tilted away from the sun and receives less sunlight. Overall, the tilting and revolution of the earth is the main reason for the causation of different seasons.
Therefore, all the given statements are true with respect to the northern hemisphere.
