NOTE: In RNA, the pentose sugar is ribose and not deoxyribose. RNA contains uracil in place of thymine.
See attached file for the table.
The answer is; student 1
The reason RNA is a ribose sugar is because it’s pentose rings have an H, rather than an OH in DNA, in their 2’ carbon. DNA has deoxyribose sugar in comparison. In addition, rather than having Thymine base (bases attach to the 1’ carbon in the rings), like in DNA, this base is replaced by Uracil (so Uracil binds complementarily to Adenine in RNA).

Answer: "Dyslexia has a biological/genetic basis."
Explanation:
Dyslexia is a learning disorder which occurs when there is a problem with the way in which the brain processes and interpretes written materials. This makes it difficult for the individual to recognize, spell or decode words. Dyslexia is characterized by difficulty in reading.
Answer:
Dyslexia has a biological/genetic basis.
The trees in the northern hemisphere will be very negatively effected by the declining numbers of the migrating songbirds.
The reason for that is that the songbirds are the predators of the caterpillars. With the declining number of the songbirds, the caterpillars will grow in numbers.
The caterpillars are feeding on the leaves of the trees. As the numbers of the caterpillars grow, they will eat more and more leaves from the trees, thus making huge problems for the trees because they will not be able to properly perform the photosynthesis which is crucial for their survival. The trees will start to get diseased and lot of forests in the Northern Hemisphere will be destroyed.
