B. RNA contains ribose and thymine
C. RNA contains uracil and ribose
D. RNA contains uracil, thymine, and ribose
DNA and RNA differ in their structure and function. DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil. RNA transmits genetic information from DNA to proteins.
The key differences between RNA and DNA are found in their structure and function. DNA (Deoxyribonucleic Acid) contains deoxyribose sugar, has thymine as a base (along with adenine, guanine, and cytosine), is double-stranded and primarily functions as the storage material for genetic information.
On the other hand, RNA (Ribonucleic Acid) has ribose sugar, contain uracil instead of thymine (the other bases are adenine, guanine, and cytosine), is single-stranded, and serves as the intermediary in the process of converting genetic information from DNA into proteins. Thus, the correct answer is: C. RNA contains uracil and ribose.

The correct answer is a - silicon dioxide.
Diatoms are single celled algae. They have a silica - based cell wall called a frustule, which gives each diatom a particular shape.
Diatoms exist as separate single cells although some may be found in groups or colonies. The ones found in colonies create very pretty forms: leaf shaped, oval , star and even like a period.
Outer shells of diatoms are quite valuable. They are used in industry in the manufacture of toothpaste to give it grit.
Answer:
Diatoms have cell walls composed of silicon dioxide.
