Answer:
All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions.
Mitosis = Division of the cell’s genetic material
Cell cycle = All the life processes of the cell, including cell division
Cancer = Disorder in which the cell cycle is disrupted, causing uncontrolled cell growth
Binary fission = Process that prokaryotic cells use to divide
Synthesis = Phase when DNA replication occurs
Checkpoint = Point in the cell cycle where the cell verifies that it is ready to go to the next phase
When a muscle cell receives a signal from a motor neuron, every sarcomere within that muscle cell is activated. The signal moves from the motor neuron to the muscle cell by crossing the synapse. When acetylcholine binds the sodium enters the T tubules and this causes calcium to be released from the sarcoplamic reticulum. Calcium binds to tropomyosin, which allows actin to bind to myosin and each sarcomere contracts. There is nothing and no way to separate individual sarcomeres. They are all activated together.
Answer:
The roots pulled up the food coloring with the water and it was transported through the xylem to the petals.
Explanation:
the xylem is one of the transport tissues in plants. It transfers water and nutrient from roots to stems and leaves.
