X^8 + x^7 + x^6 + x^5 + x^4 + x^3 + x^2 - 2x^7 - 2x^6 - 2x^5 - 2x^4 - 2x^3 - 2x^2 - 2x
= x^8 - x^7 - x^6 - x^5 - x^4 - x^3 - x^2 - x
Correct answer: D). Contradicted the accepted belief in spontaneous generation
Rudolf Virchow's and Louis Pasteur's contradicted the theory of spontaneous generation, which state that living organism originates from non-living matter.
According to this theory, it was believed that dust creates fleas, maggot arises from the rotten meat, wheat and bread left in the dark corner produces mice.
Louis Pasteur was the first scientist to prove that cells originate from the pre-existing cells.
Rudolf Virchow proposed that Omnis cellula e cellula, which means each cell comes from another cell.
1 is C - see first attachment. Genotypes with Y's represent males, and big R represents red eyes, while little r represents white eyes. For example XRxr is a heterozygous (red-eyed) female, and XrYr is a homozygous white-eyed male.
2 is B because the absence of functional proteins and some ribosomes due to the mRNA strand is not as detrimental as the loss of the entire cell.
3 is B. (The insertion of 3 base pairs into a genetic sequence is the length of a single codon, meaning that only one amino acid in the entire polypeptide was added)
Answer:
Newton's Third Law of Motion
Explanation:
According to the given condition, the rocket is launched into space and it exhausts gases in the opposite direction of its movement. This condition is an example of Newton's Third Law of Motion. According to that, an action has a reaction but in an opposite direction. More precisely, if an object exerts a force on the other object, the second object will also exert an equal forceback on the first object. This condition satisfies what is mentioned in the statement and thus, it is an example of Newton's Third Law of Motion. Mathematically, it can be written as

I have attached a figure for better understanding.
