There are two continents with an ocean between them. Today, the continents have very different plants and animals on them. However, a geologist found fossils of the same type of organism on both continents. Millions of years ago, when this type of organism was alive, we know it lived in only one place. The geologist is using the fossils as evidence to argue that the two continents used to be touching. How could the continents have gotten so far apart, and how long did it take for this to happen?
Answers
Answer:
The continents could have gotten so far because of plate tectonic movement. We know that the plates are always moving so if these plates were very active then it would have caused supercontinent pangea to drift apart. This process must have taken more than a million years to happen.

How does the presence of coal in Antarctica provide evidence for continental drift?
Answers
Answer:
There have been glacial deposits founded in the tropics and coal founded in Antarctica. This supports the theory of the Continental Drift, because coal originates from tropical plants, which can only be founded in the tropics. Additionally glacial deposits can only come from Antarctica, proving the theory.

Which process is illustrated in this picture, given that the particles shown are water molecules?
a) diffusion b) osmosis c) endocytosis d) active transport
Like, right now
Answers
Answer:
The answer is A diffusion
The process which is illustrated in the given picture shown by water molecules is that of diffusion.
What is diffusion?
Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.
There are 2 main types of diffusion:
1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.
2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.
There are 2 types of facilitated diffusion one is osmosis and dialysis.

Why is there less air pressure at higher altitude?
A: Air at higher altitudes doesn't have as much air weighing down on it from above.
B: Air at higher altitudes is cooler and less turbulent.
C: The warmer, lighter air rises bringing cooler heaver air to low altitudes.
D: The molecules in the air lose mass and are less effected by gravity, significantly lowering their weight.
Answers
Hope this helps you have a good night
There less air pressure at higher altitude because the molecules in the air lose mass and are less effected by gravity, significantly lowering their weight. Thus, option D is correct.
What is the mass percent?Mass percent is the mass of the element divided by the mass of the compound or solute.
Step 1: Calculate the mass of the compound.
mCH₄O = 1 mC + 4 mH + 1 mO = 1 (12.01 amu) + 4 (1.00 amu) + 1 (16.00 amu) = 32.01 amu
Step 2: Calculate the mass of hydrogen in the compound.
mH in mCH₄O = 4 mH = 4 (1.00 amu) = 4.00 amu
Step 3: Calculate the mass percent of hydrogen in the compound.
%H = (mH in mCH₄O / mCH₄O) × 100%
%H = 4.00 amu / 32.01 amu × 100% = 12.5%
The mass percent of hydrogen in CH₄O is 12.5%.
CO2 = 1.580 grams H2O = 0.592 grams Lookup the molar mass of each element in the compound Carbon = 12.0107 Hydrogen = 1.00794 Oxygen = 15.999 Calculate the molar mass of CH4O by adding the total masses of each element used. 12.0107 + 4 * 1.00794 + 15.999 = 32.04146 Now calculate how many moles of CH4O you have by dividing by the molar mass.
Therefore, There less air pressure at higher altitude because the molecules in the air lose mass and are less effected by gravity, significantly lowering their weight. Thus, option D is correct.

What is a fossil?A fossil refers to the mineral impression or remains of both living and non-living organisms that are generally considered to be prehistoric in nature.
This ultimately implies that, fossils are obtained from ancient organisms such as H-o-m-o Erectus, which is an organism that could walk on two (2) feet like humans.
However, amber-preserved fossils are actually very helpful in studying organisms that are generally considered to be prehistoric in nature.
