Minerals are naturally-formed substances that have a specific chemical properties: abiogenic (minerals are not produced by or derived from living organisms,  non-organic in origin), stable at room temperature (i.e. at 25 degrees C) , are represented by a known chemical formula , have an ordered atomic arrangement/structure. Coal is not classified as a mineral because it is an organic substance. Correct answer: D (coal is formed from the remains of dead plants and animals).

Cite the three main types of RNA and describe briefly the function of each.
sveticcg [70]

Answer:

mRNA: Carry genetic information from DNA to protein; serve as template for protein synthesis.

tRNA: Serves as adapter molecule and deliver specific amino acid from the cell pool to the mRNA-ribosome complex.

rRNA: Structural component of ribosomes.

Explanation:

There are three types of nongenetic RNAs: mRNA, tRNA, and rRNA.  

1. The messenger RNA (mRNA) is formed by the process of transcription in the nucleus. Transcription uses template strand of DNA to specify the nucleotide sequence in mRNA. The mRNA enters cytoplasm to join ribosomes. The nucleotide sequence of mRNA serves as a template and specifies the amino acid sequence of proteins.  

2. The transfer RNA (tRNA) serves as an adapter molecule during the process of protein synthesis and binds to the specific amino acids to deliver them to the protein-synthesizing machinery. The anticodon of tRNA binds to the complementary mRNA codons.  

3. The ribosomal RNA (rRNA) serves as structural components for ribosomes. Each of the subunits of ribosomes is made up of rRNA and proteins.

How might a single base substitution in the sequence of a gene affect the amino acid sequence of a protein encoded by the gene,
vovangra [49]
The effect differs. It could produce a different amino acid in the sequence because the corresponding codon has changed. It could also prevent the production of the originally intended sequence by changing one of the amino acids of a "start" codon (aka AUG) or extend the protein's sequence by modifying a "stop" codon (UAA, UAG, UGA or UGG), producing a new protein that might be useless or have different effects on the cell.

*<br> Which is a type of scavenger?<br> Hyena<br> Lion<br> Bear<br> Deer
DerKrebs [107]
I think that I might be HYENA.

Since they don’t really kill they are mostly “scavengers”

I am not 100% sure though. I hoped I helped at least a little.
