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:
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.

Why is the ovum so much bigger than a sperm cell?
1)It already contains all the chromosomes that will determine the zygote's traits.
2)It must store enough food for the growth of the zygote into an embryo.
3)Its big size allows the sperm to locate it better inside the oviduct.
4)A big ega is easier to implant in the uterus after tertilization.

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.
I need help with this work sheet please
Answer: 1. I would choose BbEe(black) and bbEe(chocolate) because when they crossover each other, one of the possibilities is bbEe which would be a yellow dog.
2. Yes, because when you cross the two, you will get at least 1 of each color as a result.
3. BE, Be, bE, be
4. When crossing BBee and bbee, the result was Bbee which is also a yellow dog.
5. I would not want BbEe.
6. When you cross bbEe and BBEE, the probability for a black dog would be 16/16. The other colors would be 0/16.

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.

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.

Please help... This is middle school stuff. It'll be easy for you.
Answer:
Volcano eruptions-when one plate is submerged below another, it melts and goes back to the surface as magma and creates a volcano
Earthquakes- when 2 plates slide against or hit each other
Seafloor spreading- where divergent plates move away from esch other, magma goes up to the surface and solidifies
Mountain formation- When two convergent continental plates hit each other. Continental plates are light so instead of submerging, they both rise higher to the surface and creates high land(mountains)
