Answer:

The answer is: Scientific theories do not become scientific laws; they are explanations for natural phenomena based on evidence.

Explanation:

The other answers talk about how 1) Science should be bias or opinion based 2) Scientists only take each other's word and 3) Science never changes. All of these are false. Science <em>does </em>sometimes change, it should <em>not </em>be bias or opinion-based, and scientists do not always take each other's words.

Explain the difference between prezygotic isolating mechanisms and postzygotic isolating mechanisms.

anastassius [24]

<h3><u>Answer and Explanation;</u></h3>

Prezygotic isolation is a type of reproductive isolation that occurs before the formation of a zygote can take place. In most cases mating does not even occur. Forms of prezygotic isolation include spatial, behavioral, mechanical and temporal isolation.
Postzygotic isolation on the other hand occurs after members of two different species have mated and produced a zygote. Forms of postzygotic isolation includes; hybrid sterility, hybrid inviability and hybrid breakdown.
Therefore; Prezygotic isolation prevents the fertilization of eggs while postzygotic isolation prevents the formation of fertile offspring.

Which of the following E. coli proteins is responsible for advancement of the mRNA during translation?A. EF-G

77julia77 [94]

Answer:

The correct answer is option A. "EF-G"

Explanation:

As its name implies, the elongation factor (EF-G) of E. coli is one vital protein that participates during the elongation phase of translocation. EF-G catalyzes the GTP-dependent ribosomal translocation step, which allows the ribosome to change from its pre-translocational to the post-translocational state, moving the process from the P to the E site of the ribosome.
