DENIUS [597]2 years ago

Answer A seems like the best choice for this question. Just think about some of the synonyms for therefore—”hence,” “consequently,” and “thus.” Because the adverb therefore often plays the role of a conjunction, it's sometimes called a conjunctive adverb.

B isn’t the correct answer to this question because you use “On the other hand” to introduce two contrasting points, facts, or ways of looking at something.

C isn’t the correct answer because we are not comparing or contrasting anything in this sentence.

D isn’t the correct answer because “Especially” is used in a formal sentence example: She can't be sure she will win, especially at this early stage of the campaign.

A forensic scientist is trying to find out the number of adenine in the DNA sample that he obtained from a crime scene.
Anuta_ua [19.1K]

The right answer is The number of adenine will be equal to the number of thymine.

Chargaff's rules indicate that the DNA of any cell or organism must have a ratio of 1 to 1 between purine bases and pyrimidine bases and, more specifically, that the amount of guanine is equal to the amount cytosine, and that the amount of adenine is equal to the amount of thymine. This trend is found in both strands of DNA.

why might it be beneficial to regulate what species of plats and animals people are allowed to own in particular environments
Neko [114]
Hi there!

Regulating species and plants in a certain area is beneficial for a lot of reasons. Below I'll list one of the most important reasons for regulating.

- Invasive species. As a direct result of the danger invasive species pose, regulating animals and plants in an area can help reduce the risk of a non-native species wrecking havoc on the environment. In the past and as of today many pet owners buy plants and animals from across the globe. Once they get too big some release them into the environment without any regards for the potential disaster it could bring. An example of this would be the Burmese Python which completely upset the ecosystem of souther Florida once let loose.
