What did Chargaff discover while studying bases in the DNA of organisms? The bases in the DNA of each organism were unique. The

ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine. The overall percentages of bases were different from one organism to the next. There were equal amounts of all four bases in every organism, or 25 percent of each base.

Answer: The correct answer is - The ratios of Thymine and Adenine were similar, as were the ratios of Guanine and Cytosine.

According to the Chargaff's rule, in a DNA molecule, the amount of Guanine (G) is equal to the amount of Cytosine (C) and the amount of Adenine (A) is equal to the amount of Thymine (T).

This is because A pairs with T and G pairs with C.

This means that the ratio of T and A are similar, as are the ratio of G and C.

Q6: A
Q7:D
Q8:C

Reasoning
Q6: Based on all the other questions talking about common ancestors I deduced that to find a “common” ancestor they need to find things that are the same.

Q7: All arthropod have a exo skeleton for example a lobster or crab. They all have a head, abdomen and thorax for example ants. They all have legs with joints for example a spider.

Q7:So bones are traveled down by ancestors so the types of bones stay the same but natural selection has changed them to better fit their environment.

Hi!

It's interesting to note that evolution is a <em>proven fact</em>. It is also interesting to note that a <em>theory </em>can be a <em>proven fact. </em>

So, with this in mind, the idea of evolution by natural selection is a <em>theory. </em>A theory cannot become a law! 

It also isn't a hypothesis, as it is far beyond that. A hypothesis is just what you think will happen in an experiment.

This is a theory!

Hopefully, this helps! =)

How does water transfer when it evaporates from the ocean?​
3241004551 [841]

Answer:Most of the water that evaporates from the oceans falls back into the oceans as precipitation. Only about 10 percent of the water evaporated from the oceans is transported over land and falls as precipitation. Once evaporated, a water molecule spends about 10 days in the air.

Punnet squares are your friend with these kinds of questions :)

   <u>   A  |  a  |</u>
A <u>| AA | Aa |</u>
a <u>| Aa | aa |</u>

Now we can easily see that 1/4 of the offspring will be AA, 1/2 will be Aa, and 1/4 will be aa. Therefore, it is the third answer that's correct (1/4 AA, 1/2 Aa, 1/4 aa). Hope this helps! :)
