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?
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.
Explanation:
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.
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.

Two types of worms exist in London. One which comes out during the day and the other which come out at night. The day worms are eaten more often by the birds.
i) After a few years only night worms existed in the region. Why? (2)
ii) What kind of selection has taken place? (1)
i) Because the worms would have either learned to become night worms or all day worms would have been eaten faster than they could reproduce
ii) Natural selection. Humans had no interaction with which worms survived, so it's all natural.

remnants of a dead organism.
b. Amber-preserved fossils are the most
common form of fossils and are actually the
least helpful in studying organisms.
c. A mold fossil is an imprint of the organism on
the rock.
d. Petrification is the result of a dead organism
hardening and turning to stone or rock, as
seen in petrified trees.
Answer:
a. A trace fossil is a fossil created from the
remnants of a dead organism.
Explanation:
All of the aforementioned statements regarding fossils are true except: B. Amber-preserved fossils are the most common form of fossils and are actually the least helpful in studying organisms.
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.

God blessed youWhich 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
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.

It converts energy to food.
Answer:
It is used by every living thing.
Explanation:
This would be correct because all living things use cellular respiration.
Cellular respiration does not produce oxygen in all cases. In animals and humans, cellular respiraction actually produces carbon dioxide. It definitely does not convert energy to food and it does not necessarily require water to be performed.

Explain how heat can be a source of water pollution.
Answer:
Decreases amount of available oxygen in water causing some fish to decay because of the lack of oxygen.
Explanation:
Heat boosts fish metabolism and lowers water's ability to hold dissolved oxygen, making it a water pollutant. Low-dissolved oxygen water kills game fish like trout.
Why is heat a source of water pollution?The ability of water to keep dissolved oxygen in solution is reduced when heat is present, and fish have a faster metabolic rate when heat is present. For these reasons, heat is regarded to be a pollutant in water. In waters with exceptionally low concentrations of dissolved oxygen, game fish such as trout and other valuable species simply are unable to live.
The release of warm water into existing bodies of water is referred to as thermal pollution. Thermal or nuclear power plants, industrial effluents such as petroleum refineries, pulp and paper mills, chemical plants, steel mills and smelters, and sewage effluents, as well as biochemical activity, are the primary contributors to thermal heat pollution. Other contributors include biochemical activity.
