Chemosynthesis Quick Check
Just took it xd <3
The compound can provide the energy for chemosynthesis is light photon and carbon dioxide. Thus, option C is correct.
What is photon?
The energy stored in bundles or the packets has been known as the photon. Chemosynthesis has been referred to the process by which some organism obtain food from inorganic chemicals rather than from light. There are many chemosynthetic bacteria that obtain food by the metabolism of methane, hydrogen sulfide or carbon dioxide.
Light photons are not required for chemosynthesis. It is only necessary during photosynthesis. Chemosythesis has been involves the inorganic chemicals therefore, light photons are not required during chemosynthesis.
The organism which provides evidence that matter and energy can be cycled through an ecosystem without sunlight is a lanternfish on the Atlantic Ocean floor and the technique which will prove most effective to eliminate the greatest number of organisms is to remove methane and hydrogen sulfide.
Therefore, The compound can provide the energy for chemosynthesis is light photon and carbon dioxide. Thus, option C is correct.

Given sin 0 = 4/5
use the Pythagorean Theorem to find the value of cos 0.
A) cos 0 = 3/4
B) cos 0 = 3/5
C) cos 0 = 4/3
D) cos 0 = 4/5
Answer:
cosθ = 3/5
Explanation:
Given that,
sinθ = 4/5
We need to find the value of cosθ.
We know that,
sinθ = P/H
Where
P is perpendicular and H is Hypotenuse
Using Pythagoras theorem to find base (b).
H²=P²+B², b is base
We have, H = 5, P = 4, B=?
b²=5²-4²
b=3
We know that, cosθ = B/H
Putting all the values,
cosθ = 3/5
Hence, the correct option is (b) "cosθ = 3/5".

why would breeding year round favor natural selection?
Answer:
Only the strongest would survive each year and be able to breed
Explanation:
According to Darwin's theory of evolution if an animal were to be put into terrain whether local or new, the animal would need to adapt as its surrounding slowly change. If said animal is unable to adapt in time it will perish or be unable to produce strong offspring that will survive.
Which of the following statements about plankton or nekton is NOT correct?
a. Nekton are active swimmers.
b. Phytoplankton are important primary producers.
c. All plankton are closely related to plants.
d. Plankton drift or swim weakly.
e. Zooplankton are heterotrophic plankton.
Answer:
C. All plankton are closely related to plants.
Explanation:
Plankton are organisms found in water that exist in a drifting state. They are too small or weak to swim on their own, so they let the current or tide carry them. They are usually microscopic but include larger species as well, such as some crustaceans and jellyfish.
Phytoplankton are autothrophic plankton. This means that they produce their own food. They are primary producers and closely related to plants.
Zooplankton are heterotrophic plankton, which means that they feed on other organisms. They are animals and aren't closely related to plants.
Nekton are organisms found in water that swim actively.
Based on this information, we can conclude that statement C is the only incorrect statement.
_____ is caused by stress and is the bending, tilting and breaking of rock.

The hydrogen atoms have a partial negative charge and are covalently bonded to the oxygen atom in another molecule, which has a partial negative charge. C. The hydrogen atoms have a partial positive charge and are covalently bonded to the oxygen atoms in another molecule, which have a partial negative charge. D. The hydrogen atoms have a partial negative charge and are attracted to the oxygen atom in another molecule, which has a partial negative charge.
Answer:
A. The hydrogen atoms have a partial positive charge and are attracted to the oxygen atom in another molecule, which has a partial negative charge.
Explanation:
I just took the quiz. That was the correct answer.
The hydrogen atoms have a partial positive charge and are attracted to the oxygen atom in another molecule, which has a partial negative charge. The correct option is A.
What is a hydrogen bond?A hydrogen bond or H-bond is an electrostatic attraction between a hydrogen atom covalently bound to a more electronegative "donor" atom or group.
Another electronegative atom weighing down a lone pair of electrons the hydrogen bond acceptor.
Since the electron is not shared evenly between a hydrogen atom and a negatively charged atom, hydrogen bonding occurs.
Hydrogen in a bond still has one electron, whereas a stable electron pair requires two electrons.
Hydrogen bonds form between adjoining hydrogen and oxygen atoms of adjacent water molecules in the case of water. A hydrogen bond is formed by the attraction of individual water molecules.
Thus, the correct option is A.

A person invested \$6,000$6,000 in an account growing at a rate allowing the money to double every 11 years. How much money would be in the account after 19 years, to the nearest dollar?
Answer: $19,866
Explanation:
We know that the initial investment is $6,000. And it doubles every 11 years.
Then after 11 years, the amount of money will be 2*$6,000
After another 11 years (a total of 22) the amount of money will be 2*(2*$6,000)
or $6,000*(2)^2
We already can see that this is an exponential growth equation.
After n times 11 years, the amount of money will be;
M = $6,000*(2)^n
But n represents groups of 11 years, then if y represents the number of single years, we can write the equation as:
M = $6,000*(2)^(y/11)
You can see that y = 11 is equivalent to n = 1
y = 22 is equivalent to n = 2
and so on.
Then the equation:
M = $6,000*(2)^(y/11)
Tell us how much money will be in the account after y years.
Now we only need to replace y by 19, to get:
M = $6,000*(2)^(19/11) = $19,866
Where i rounded the amount of money to the nearest dollar.
