B
An inorganic mineral is not composed of anything that was once alive
Explanation:
Organic minerals made from life. They mainly make up the biosphere and examples are minerals in plants and animals. Even after the death and decomposition of the living organisms, the minerals from the decomposition are considered organic. Organism matter is mainly made up of carbon and hydrogen.
Inorganic material, on the hand, are not derived from life and include substances like metal elements and inorganic salts.

answer is the first1 off spring to parants
Oxbows and loess both show similarity as they both show the constructive power of erosion. An oxbow lake starts as a curve in a river. Oxbows are formed where the river often empties into another water body. ... A loess is a sediment which is formed by the accumulation of the wind blown silt
I’d like to believe the answer is C. Inbreeding tends to increase the proportion of homozygous individuals in a population.
Answer:
If an mRNA strand is 6399 nucleotides long, it will code for 2132 amino acids, as the last triplet is the terminating codon.
Explanation:
Codons are found in the RNA chain and are made up of nucleotides trios, whose specific sequence determines the genetic code.
There are 4 nitrogenous bases in RNA - Adenine, Guanine, Cytosine and Uracil - which when combined in trios give rise to 64 possible codon combinations that code for 20 amino acids, so an amino acid can be formed by more than one codon.
Determining how many amino acids are encoded according to the amount of nucleotides in the mRNA would be as easy as <u>dividing the number of nucleotids in the chain by 3</u>, but considering that the last codon is not taken into account, since it is the termination codon.
- Amino acids = (amount of nitrogenous bases in mRNA / 3) - 1
- Amino acids = (6399 / 3) - 1
- Amino acids = 2133 - 1 = 2132
