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
The correct answer is B, I know this because none of the other answers are even reasonable. For example-
A is wrong because the size of elephant tusk has not changed over time, elephant tusk just grow...
C is wrong because it makes no sense to hunt elephants with no tusk :/
D is completely wrong because tusk have nothing to do with reproduction, those are two completely separate bodily functions.........
Answer:
Microbes play an incredibly important role in research. Many of the breakthroughs in molecular biology, such as understanding how the genetic code works and how genes are used to make proteins, were made by scientists studying microbes in the laboratory

The species likely living in an ecosystem on the other side of the mountain farthest from the coast is the cactus.
- Cacti are evergreen plants. Their stems might be meaty or succulent, cylindrical or flattened.
- The stems are green in colour and photosynthetic, usually fulfilling this job instead of leaves, which are scarce or nonexistent in most adult cacti.
Most cactus species are well-defended by spiky bristles and spines that repel most animals.
- Cacti are xerophytic plants, which means they are physiologically and morphologically suited to the high water shortages of dry ecosystems like deserts.
- Cacti's xerophytic adaptations include (1) succulent, water-retaining stems, (2) a thick, waxy cuticle, and few or no leaves to decrease water losses through transpiration.
