Is non-gene coding DNA considered junk DNA? Explain why or why not?
The non-gene coding portions of DNA are no longer considered junk DNA. Why? Because just because the DNA doesn`t code for a gene doesn`t mean it`s useless. We`ve discovered that many of the so-called junk portions of DNA code for mRNAs and snRNAs under the right conditions. These forms of RNA can catalyze certain processes just as if not more effectively than a gene which will make a protein can. If fact, it`s believe that mutations in these non-coding regions of DNA might result in some of our genetic diseases such as Type I Diabetes.

Which of the below sentences is correct: A) I rode in the train. B) I rode next to the train. C) I rode on the train. D)I rode in front of the train.
The correct answer is C. Why? Because trains are considered platforms. Trains have such a large floor space that the floor space is considered a platform instead of a container. Therefore, we have to use "on" for things with large amounts of floor space like ships, buses, and trains. However if the area has a small floor space, we use "in". Cars and hot air balloons have very small floor spaces, so we must use "in" since it`s classified as a container space not a platform.

Throughout the years, it`s been discovered that a more active, playful teaching style is better for student learning. A student learns best when their mind is relaxed. When the mind is relaxed by a more active style of teaching, a student is able to more effectively retain information. Please find the grammatical error in the sentences located above.
The answer is the "their" located after "A student..." in the second sentence. This "their" should actually be a he or she because the pronoun must agree with the singular "student" noun that it is referring to.
