B. The flower color in a population changes over time.
Answer:
Diamonds are extremely durable and graphite (pencil lead) is very fragile.
Explanation:
Answer: 20 amino acids
Explanation:
The Genetic code permits the triplet nature of codons whereby three nucleotides from Adenine, Uracil, Guanine and Cytosine on the messenger RNA (mRNA) join to form 64 codons.
Since more than one codon can specify for an amino acid, the 64 codons then specify for 20 amino acids, that then form the sequence of various proteins
Carbon dioxide is a colorless and non-flammable gas at normal temperature and pressure. Although much less abundant than nitrogen and oxygen in Earth's atmosphere, carbon dioxide is an important constituent of our planet's air. A molecule of carbon dioxide (CO2) is made up of one carbon atom and two oxygen atoms. Carbon dioxide is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.
Modern Prokaryotes are sing celled organisms without complex organelles.
