Why does a hypothesis have to be falsifiable? question 5 options: a it must be able to pass all its tests b all of the above c it must be possible to show that it is wrong d. it can be right only if it is found to be false

Option D,  It can be right only if it is found to be false

Explanation:

A hypothesis has be falsifiable because only then a theory or research statement can be proved right. Usually a hypothesis  is considered in a way that it is a negative representation of a fact.

For example -

If sun in round in shape and this statement is to be tested, Then the hypothesis assumed shall be

H1: Sun is not round.

And in case the main motive of researcher shall be to prove this hypothesis as false as only then he/she will be able to prove that "sun is round"

Hence, option D is correct.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
