If it wasn't for___reproduction, the passing of mutations from one generation to the next would continue.

Answers

Answer: If it wasn't for Sexual reproduction , the passing of mutations from on...

Explanation:

There are several types of reproduction that living things present, but they can all be grouped into two broad categories: asexual and sexual reproduction. Sexual reproduction considered to be more complex is characterized by the presence of meiotic gametes and, consequently, by recombination of genes, resulting in genetic variability, genetically different from their progenitors. It can occur by conjugation (present in bacteria, protozoa, and algae), autogamy (present in protozoa) and syngamy (present in most living things).
Sexual reproduction because it provides sexual diversity

The information that can be determined by observing dark lines within the spectrum of a given star includes "the approximate size of the star" since the other options are unknown. 

Answer:

the elements present in the star's atmosphere      

Explanation:

The spectrum showing dark lines is an absorption spectrum. The dark lines actually indicated the energy absorbed by the elements present in the atmosphere of the star.

The elements absorb particular wavelengths and reach higher energy state. The absorbed wavelengths appear as dark lines in the spectrum.

Which of the following is not a good polling technique? A. asking clear questions B. using a push poll C. using a large sample D. using a random sample

Answers

Question is which is NOT a good technique.
Answer is "B" and here's why:

A) Clear questions -- good. People understanding the question will answer accurately.
C) Large sample size -- good. Answers will be more accurate with more people asked (like if you flip a coin 1,000 times its going to be closer to 50% heads than if you only flipped it twice)
D) Random sample -- good. Avoids your own bias in choosing who to ask.

B) Push poll -- bad. Pretends to be unbiased, the pollster's real objective is to get a person thinking in a way that is to their advantage. Some political candidates do this just before elections.
