Answer: option D) Cells can function equally as well at all pH's because enzymes are effective at all pH's.
Explanation:
Studies in biology have demonstrated that:
- All living tissues have different pH (stomach is acidic, it has a pH below 7; saliva is alkaline, it has pH above 7 etc)
- All living tissues has a stable physiological temperature of 37°c
- All living tissues contain enzymes such as Catalase
Thus, based on the information given, we can infer that all cells can function equally as well at all pH's (whether acidic, neutral or alkaline) because enzymes are also effective at all pH's.
Answer: Option C
Explanation:
Protein building begins on the DNA strand. Usually, the DNA contains genetic information which flows from nucleic acids to proteins in a series of steps:
1) Replication: this is the first step. It involves the copying of parental DNA into daughter copies.
2) Transcription: this is the second step. Here, parts of the coded genetic message in DNA are copied precisely in the form of RNA - in the form of messenger RNA (mRNA).
3) Translation: this is the third step. Here, genetic message coded in mRNA is translated, on the ribosomes, into a protein with a specific sequence of amino acids.
Simply put, DNA makes RNA, and RNA makes protein.

I dont want to mislead you, but I believe the answer is A because letter B is wrong because plants go through cellular respiration and photosynthesis, whereas animals go through cellular respiration but not photosynthesis, and for C, I've never heard of that so it doesnt seem likely.
Answer:
via hydrogen bonds; there are two between adenine and thymine and three between cytosine and guanine
