Answer:
The correct answer is peas have characteristics that have two forms.
Gregor Mendel used pea plant <em>Pisum sativum </em>as a model plant for his experiments. There are many applications behind his choice, one of which is observable characteristics with contrasting traits.
Pea plant has many observable characteristics which exist in two forms for example:
- Plant size (tall or dwarf)
- Pea color (green or yellow)
- Pod shape (yellow or green)
- Flower color (purple or white)
- Pea shape (round or wrinkled)
Other benefits were like: short life cycle, it produces a good number of offspring in a cross, easy to breed or cross-pollinate, hybrids were liable, bisexual flowers which makes it easy to produce true-breeding etc.
Answer:
B
Explanation:
many of the same organelles are located in both plants and animals cells
Homeostasis:is the state of steady internal, physical, and chemical conditions maintained by living systems.
ACh is released into the synaptic cleft in response to an action potential in the motor neuron. Gradient potentials are started when ACh binds to sarcolemma receptors.
<h3>What triggers a muscle contraction when an action potential occurs?</h3>
The ryanodine receptors (RyRs) in the SR also open and release calcium as a result of the action potential's invasion of the T-tubules, which opens the L-type calcium channels and stimulates contraction.\
Sodium ions within a muscle cell start the action potential. When a muscle contracts, calcium ions are released into the muscle cell, strengthening the muscle. This occurs after the cell becomes positive, starting the action potential.
ACh is released into the synaptic cleft in response to a motor neuron action potential.
