<span>Charles Darwin theory is theory of biological </span>evolution, that explains how modern organisms evolved over long periods of time through descent from common ancestors. Evolution is the process of change over time and Darwin explains in his theory the changes in humans over time and <span>shows how the living world is constantly changing.</span> This is the reason why cientists refer to charles darwin’s ideas about evolution as the theory of evolution.
Hydrogen Gas has been nonexistent in the atmosphere since that time period
The mass number, also known as an atomic mass number or nucleon number, refers to the total number of neutrons and protons (in a combination known as nucleons) in an atomic nucleus. It determines the atomic mass of atoms. However, while calculating the mass number, the small contribution of mass from electrons is ignored.
Mass number is equal to Number of protons + Number of neutrons
Mass number = 11 + 7 = 18.
Hence, the correct answer is 18.
It would be C
<span>Deflation is wind activity which also causes rock erosion or transports sand and dirt.</span>
Answer:
Option: A and D are the correct answer.
A. 50% and D. 25%
Explanation:
We know that the probability of an event is the chance of occurring of an event.
The probability of an event always lie between 0 and 1.
It is equal to zero if the event will never occur and is equal to 1 if the event is certain to occur.
Also, the probability could be in ratio or it could be in percentage and the percent may be between 0%-100%
Hence, in the given options:
B) 557 is incorrect as the probability is greater than 1.
c) 1×104=104 is incorrect since the probability is greater than 1
Hence, the correct options are:
A. 50%
and D. 25%
