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!
7. Challenge yourself: You have already learned that mutation is one source of
variation in a population. Based on what you have just seen, what is a second
source of variation?
(I just need more information or explanation) please
Answer:
Natural selection would be the other source because organisms that have a beneficial trait will live, but organisms that do not have a beneficial trait might die. So the organsims that do survive will reproduce and pass on those traits to their offspring. Eventually all the organisms that do not have a beneficial trait will die out, leaving most of the population having that beneficial trait.

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.

A. an increased number of Argentine ants B. an increased number of native ants C. no dependence between the populations of the two ant species D. an equal number of Argentine and native ants
Answer:
The answer is C.
Explanation:
No dependence between the populations of the two ant species.
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.

A different couple has a child with O type blood who has a blood disorder and
needs regular transfusions. The mother is type B, and the father is type A. A
genetic counselor created a punnett square to show them the chance of having
another child with type O blood. The results are shown below:
What is the chance of the couple producing another child with type O blood? __%
Answer:
25%
Explanation:
A simple way to think of the punnett square is to think of it as divided into fourths. Only one of these fourths has o type blood. Therefore, there is only a 1/4 or 25% chance of them having another child with o type blood. Hope this helps :)

What is the importance of forest to the stability of ecosystems and why does deforestation still take place despite the negative impacts?
Answer:

Answer:
Forests help provide many essential resouces such as wood, leafs, bark, food, oxygen, and maybe water if their are lakes. For the second question, mostly human activity, and carbon dioxide happen to negatively affect the forests, people are the stimulis to deforestation.

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.

A type of mountain formed when magma collects beneath an overlying rock layer, forcing the layer upward into a blister-like structure is known as a domed mountain.
What is magma?Magma has been defined as the molten or the semi-molten material which is natural and from magma all igneous rocks are formed. Beneath the surface of the earth magma has been found and there are very proofs of magmatism and it has been observed on the other terrestrial planets as well as some of the natural satellites.
Sedimentary rocks are generally made up from directly heat and these are formed when deposition or accumulation of particles that are organic or minerals at the surface of Earth, later followed by the process of cementation. The main feature of sedimentary rock is that they are formed in multiple layers.The rocks are made up of more than one mineral and the size of some rocks are small or big it depends upon their constituents.
Therefore, A type of mountain formed when magma collects beneath an overlying rock layer, forcing the layer upward into a blister-like structure is known as a domed mountain.
