Answer:
The correct answer will be- the vascular system
Explanation:
The plants and algae evolved from a common ancestor and studies have also found that the algae-like Chara also evolved into plants.
The plants became adapted to grow in the terrestrial habitat by modifying themselves. The modification was that they developed the vascular system which helps them in conduction of the nutrients and water from the soil to the top of the plants and also the food to every part of the plant.
The plants also added the deposition of the cutin layer over their structure which allows the plants to stand straight and few amounts of loss of water from the plants.
Thus, the vascular system is the correct answer.
Endothermy is the proper term for this. I got a 100% on the test.
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.
