The most generally accepted form of conclusive evidence for the theory of Evolution is the fossil record.
<h3>What is the theory of Evolution?</h3>
- The theory of evolution was proposed by Charles Darwin.
- It states that as time passes, organisms evolve to better adapt to their environments.
- This is closely related to natural selection, which is considered a <em><u>driving force of </u></em><em><u>evolution</u></em><em><u>. </u></em>
<h3>How the fossil record supports this theory</h3>
- The fossil record provides essential data to support this claim.
- The data comes in the form of the comparison between fossils of two closely related organisms, separated by a matter of generations, that <em><u>present changes in the genetic code that made them more apt for survival.</u></em>
Therefore, we can confirm that the most generally accepted form of conclusive evidence for evolution is the presence of <u>fossils </u><u>that show the genetic correlation between two organisms and the progression of </u><u>evolution </u><u>between them. </u>

Answer:
The answer is 0.75M HCl
Explanation:
To calculate the concentration of 10 ml of HCl that would be required to neutralize 50.0 mL of 0.150 M NaOH, we use the formula:
To calculate the concentration of 10 ml of HCl that would be required to neutralize 50.0 mL of 0.150 M NaOH, we use the formula:
C1V1 = C2V2
C1 = concentration of acid
C2 = concentration of base
V1 = volume of acid
V2 = volume of base
From the information supplied in the question:
concentration of acid (HCl) is the unknown
volume of acid (HCl) = 10ml
concentration of base (NaOH) = 0.15M
volume of base (NaOH) = 50ml
C1 x 10ml = 0.15M x 50ml
C1 x 10 = 7.5
divide both side by 10
C1 = 0.75M
concentration of acid (HCl) is 0.75M
Answer:
Among the given options which one best suits the definition of an element?
Explanation:
Element:
Element is the pure form of matter which cannot be broken down into new simpler substances either by physical or chemical means.
It is made up of the same type of atoms.
For example:
Copper, silver, gold, oxygen, etc.
Among the given options:
the third option that is elements are made of atoms is the correct option.
Remaining statements:
Elements are made up of complex chains of carbon and oxygen is wrong,
Elements can be broken down into other simpler substances is wrong.
Because we don't get any simpler substances from elements.
For example, if we break a gold rod many times also only its size varies and no new substance is obtained from it.
All elements have the same chemical properties is a wrong statement.
Because each element is unique and it has its own properties.
H₂O + H₂O ⇌ H₃O⁺ + OH⁻
