Answer:

The three most common ways that bacteria diversify their DNA are transformation, conjugation, and transduction. Genetic Material: the material in our cells that makes us who we are inside and out.

Deoxyribonucelic Acid (DNA): hereditary material found in the nucleus.

Ribonucleic Acid (RNA): genetic material that differs from DNA through its chemical bases.

DNA contains all the secrets that make you so awesome! So, it is super important that the cell keeps the DNA safe. DNA has so much information that it could stretch from the earth to the sun four times! No seriously, four times! I'm sure you're thinking, how does all that information get into something so small? Well, DNA is highly organized in order to keep all information safe, yet accessible to the cell. This is a great thing because you don't want to lose your awesomeness! DNA is comprised of four chemical bases also known as nucleotides: adenine (A), guanine (G), cytosine (C), and thymine (T). These bases pair with one another, A with T and C with G. Each base is attached to a sugar (ribose) and a phosphate molecule: hence the name deoxyribonucleic acid.

Now that we have the basic building blocks of DNA, let's get into the structure. DNA is double stranded, and each strand is held together by the pairing of the nucleotides. Remember what we mentioned above: A loves T and C loves G. These bases never cheat on one another; they only pair with the partner they love! The double stranded DNA is spirally coiled to form a helix. You will find many textbooks refer to DNA as a double helix. This double helix looks much like a ladder with the nucleotides representing the rungs on the ladder and the sugar and phosphate are the sides. The double helixes are then wrapped around proteins called histones and packaged into chromosomes.

The other type of genetic material called ribonucleic acid (RNA) is structurally similar to DNA, but there are a few differences--primarily in their chemical bases. Before we get more into the differences, let's examine the similarities. Both have a sugar, phosphate group, and four chemical bases. Unlike DNA which is double stranded, RNA is single stranded. The other major difference is the bases that are found in RNA. RNA contains adenine (A), guanine (G), cytosine (C), and uracil (U). So, in RNA the base thymine is replaced with uracil. In RNA the base pairs are A loves U and C loves G.

devlian [24]

Answer: All of them seem to apply.

Explanation:

A., Its important to know if your car that is being collided is a small car or big truck, as they will end up effecting who gets hurt the most.

B., Same thing as A. but with the other vehicle.

C., The velocity matters a lot with a collision, since a slow crash won't have as much damage as a car going fast and hitting someone. Also it won't be as likely to be fatal if the car crashing into you is going slow.

D., This is the only one I'm not too sure on, but it seems like how fast the car can accelerate once collided with would be a big factor on whether it would come to a halt or skid across the road.

Experimentation and data collection provides solution to certain problems. It helps to solve an hypothesis formulated providing results and serve as guide for further experiments.

1. A scientific hypothesis is best described as an "educated guess." - False

2. Failure to disprove a hypothesis proves that the hypothesis is correct.- False

3. Scientific theories are never questioned.- False

4. A scientific theory is based on educated guesses and is not backed up by facts/data.-False

5. Scientists that contribute data that contradicts an established theory are not highly regarded in the scientific community.- False

7. Scientific facts are never questioned.-False

The True

6. In order for an investigation to be considered scientific, a controlled experiment must be used.- True

A control serves as a guide in an experiment as the experimental variable is tested with it to see the possible changes or outcome.

8. Science can only answer questions about things that can be seen and observed.- True

Science provides solutions to problem that have been identified, for which data are generated in respect to the problem identified and solutions are provided.

9. Untestable hypotheses fall outside the realm of scientific inquiry -True

An hypothesis should be testable, it is the problem statement that requires a solution.
