Answer:
The pericardium is the most outer layer of the heart. Main function to protect the heart from external forces/entry.
Answer:
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Explanation:
Nerve cells release neurotransmitters in the synaptic cleft which are capable of affecting nearby cells such as other nerve cells and muscle cells. Neurotransmitter molecules include, among others, serotonin, acetylcholine, dopamine, norepinephrine and histamine. Moreover, the synaptic cleft is the space that separates a neuron cell and its target cell. On the other hand, neurons transmit signals through electrical impulses. Electrical impulses travel long distances in the body carried by axons of the nerves. Thus, nerve impulses connect the brain and spinal cord and they carry signals to different parts of the body.
Answer:
1.) The solute molecules will not move between the two sides because the membrane does not have large enough spaces for the molecules to move through. The water molecules will move to the right side because water moves to places of a higher solute concentration.
2.) The right side represents high concentration because it contains the majority of the solute molecules.
3.) The left side represents low concentration because it contains a small amount of solute molecules compared to the right side.
Answer:
B
Explanation:
a conclusion is a definite wrap up to a theory or experiment, in option A the experiment is ongoing, option c, the option is still a theory, option D is your question that made you experiment not the conclusion, therefore b is the conclusion since it gives a definite answer to the problem/experiment
