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.

Which of the following is an example of maintaining homeostasis? Learning Jumping Shivering Smiling
Anestetic [448]
The answer is D, sweating.

Homeostasis is where the body uses some mechanisms to maintain a optimum condition for the body to function. These conditions may include body temperature, blood glucose level etc.

Sweating is a mechanism that can help maintain the body temperature. During hot conditions, the sweat glands under the skin surface may produce sweat, which is then released to the skin surface. When the sweat is on the skin surface, they evaporate. During evaporation, heat energy is brought away from the skin as the sweat molecules that have a higher kinetic energy (=temperature) escaped from the sweat drop. The average temperature of the sweat is reduced. Eventually, the temperature of the body is decreased and this help maintain the suitable temperature for the body to function.

Therefore, your answer is D, sweating.

Choose all that apply.
Elodia [21]

The correct answers are options:

1. Amphibians evolved before land reptiles.

4. Elephants appear in the fossil record after dinosaurs became extinct.

The relative dating is a technique of dating with respect to any past event. In this case, two events are discussed to be occurred in a sequence related to one-another. In the option 1, the amphibians are said to be evolved before reptiles. So, the evolution of the amphibians is relatively dated with the evolution of reptiles. Same in the option 4, the evolution of the elephants is relatively dated with the extinction of the dinosaurs.
