Answer:
The best answer to the question: The Z disc forms the end____ of a sarcomere, would be: the end border, or the point where sarcomeres join, within a muscle fiber.
Explanation:
Concretely, a Z disc is the boundary line that divides sarcomeres within a muscle fiber. They are the bordes between sarcomeres and they contain the most important molecule, actin, which forms the thin filaments essential for muscle tissue movement. This actin molecule, present along the Z discs, under the correct stimulation and circumstances, will bind to myosin and thus movement will be possible.
Answer:
500 amino acids
500 codons
Yes
Explanation:
A codon is a set of 3 base pairs. Each codon codes for a specific amino acid. So the ratio between codon and amino acid is 1:1 and the ratio between base pairs and codon is 3:1.
If you have 1,500 base pairs then we can mathematically solve the number of codons:
Since the ratio of codon to amino acid is 1:1, then for every 500 codons, there are 500 amino acids.
I hope this helps clear it up a bit for you.
Aquatic life transitioned to terrestrial life when anatomy structures began to change in ways such as fins slowly evolved into legs, gills into lungs, and instead of suction feeding they started to bite instead.
Answer:
Explanation:
The vertebrate land invasion refers to the aquatic-to-terrestrial transition of vertebrate organisms in the Late Devonian epoch. This transition allowed animals to escape competitive pressure from the water and explore niche opportunities on land. Fossils from this period have allowed scientists to identify some of the species
