In which ways are RNA and DNA different?a. RNA has ribose sugar, DNA has deoxyribose sugar
b. RNA has uracil, DNA has thymine
c. RNA is single-stranded, DNA is a double-helix
d. all of the above

Answers

Answer 1
Answer:

Answer:

d. all of the above is the correct answer.

Explanation:

These are the main difference between RNA and DNA

  • Sugar present in RNA is ribose sugar whereas sugar present in DNA is deoxyribose sugar.
  • Nitrogenous bases present in DNA are adenine, guanine, cytosine, and thymine whereas in the case of RNA nitrogenous bases present are adenine, guanine, cytosine and uracil which is replaced by thymine in DNA.
  • RNA is single-stranded whereas DNA is a double-helix.

thus the all the above(D) options are correct.
Answer 2
Answer:

Final answer:

RNA and DNA differ in three major areas: the types of sugars they contain, the bases they use, and their structure. RNA contains ribose sugars and the base uracil, while being single-stranded. In contrast, DNA contains deoxyribose sugars, the base thymine, and has a double helical structure.

Explanation:

RNA and DNA, which can both be found in cells, have several significant differences. To answer your question, the correct choice would be (d) all of the above because:

  • RNA has ribose sugar, while DNA has deoxyribose sugar. The difference is that the deoxyribose sugar in DNA is missing one oxygen atom compared to the ribose sugar in RNA.
  • RNA contains the base uracil whereas DNA uses the base thymine. This change makes DNA more stable and less likely to mutate.
  • Finally, RNA is single-stranded and DNA is a double helix. The double-stranded DNA is more stable resulting in a reduction in damage and loss of genetic information.

In 1831, Charles Darwin visited the Galapagos Islands. While observing the giant land tortoises that lived on these islands, Darwin noted that the shape of the tortoise shell varied depending on which island the tortoise lived. Tortoises on one island had round shells, for example, whereas tortoises on a neighboring island had more flattened, saddle-shaped shells. Which statement BEST summarizes Darwin's explanation for these differences?A) Random mutations caused the shape of the shells to fluctuate periodically. B) The shape of the tortoise shell varied because the predators on the islands were different. C) The particular shape of the shell was best suited for the island on which the tortoise was living. D) Tortoises who used their shells in special ways caused the shells to become larger, rounder, or flatter.

The uniqueness of individual offspring for many animals and plants is the result of a process called _____. mitosis meiosis

Answers

The uniqueness of individual offspring for many animals and plants is the result of a process called Meiosis.

During meiosis , the number of chromosomes in parent cell are reduced by half and produces four gamete cells.

Later on, these chromosomes are mixed into the new offspring, causing it carried out some characteristic from its parents and became a new unique individual.

The answer is meiosis.

The appearance of fireflies at dusk is an example of a circadian rhythm because it a. is related to the phase of the moon
b. is related to the temperature of the air
c. happens daily
d. happens seasonally

Answers

It is a circadian rhythm because it happens daily. That is what circadian means as a term.

the right answer is C. happens daily

The circadian rhythm is studied by chronobiology. The circadian rhythm is the study of a 24-hour period during which a number of biological and physiological mechanisms are repeated. Circadian rhythms are modeled on an internal clock that regulates the rhythm of the waking / sleeping state, the rate of nail or hair growth, the rhythm of hormone production, blood pressure, the state of alertness, body temperature ... All living organisms have a circadian rhythm.

which of the following is not a characteristic of Arthropods that has attributed to their diversity and success A. endoskeleton B. jointed appendages C. highly developed nervous system D. segmentation

Answers

A. endoskeleton

Endoskeleton is not a characteristic of Arthropods that has attributed to their diversity and success. Endoskeleton is defined as inner characteristics of the skeletal feature of an organisms such as bears, humans, fish and etc.

Exoskeleton on the other hand is the trait by which arthropods posses. It is skeletal feature that is described outside or is extrinsic, this is evident as crabs have their skeletons outside of their body.
