Answer:
c. Sarcomere
Explanation:
Sarcomere is one of the basic components of striated muscle that allows muscle contraction. That is, it is the contractile unit in the muscle cell.
The sarcomere is made up of a protein complex, the most important of which are actin and myosin. In the presence of Ca2 +, the ends of the myosin bind to nearby actin molecules and fold with great velocity. The actin filament then moves to the center of the sarcomere, triggering the approach of the two Z lines. This causes the sarcomere to shrink and, to a large extent, lead to contraction of the entire muscle.
Answer:
for starters the 5 stages are called prophase, metaphase, anaphase, telophase, and cytokines. in prophase the nuclear membrane will devolve and the chromosomes will be seeable. in metaphase the chromosomes meet in the middle. anaphase is when the spindle fibers start to move and attach to the chromosomes and start to pull and anaphase stops when everything stops moving. in telophase, well it the opposite of prophase, in cytokines it starts in the middle of anaphase and what it does is it like pinches it in two new cells.

Answer:
Target cell: this cell has a receptor that can bind the ligand. The ligand binds to the receptor and triggers a signaling cascade inside the cell, leading to a response. ... When a signaling molecule binds to its receptor, it alters the shape or activity of the receptor, triggering a change inside of the cell.
Explanation:
Cytosine
I believe, I had this question as well a while ago
Cytosine forms with guanine and adenine with thymine making cytosine and Adenine base pairs.
