Answer:
The nervous system is composed predominantly of neural tissue.
Explanation: Anatomist study anatomy, the study of the structure of organisms or their parts. By observing the structure of the nervous system, anatomist will tell that it is composed predominantly of neural tissue. So, he observed the structure of one part of an organism.
Answer: B.
Explanation:
Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth's rotation results in the Coriolis effect which also influences ocean currents.
Answer:
D (Swell and Burst)
Explanation:
Pure water contains a very low concentration of solute materials, hence it is regarded as HYPOTONIC. Since the red blood cell contains intracellular fluid that contains more solutes than the extracellular pure water it is placed in, it is said to be HYPERTONIC in comparison with the pure water.
This difference in concentration between the extracellular solution (pure water) and the intracellular fluid (red blood cell) called CONCENTRATION GRADIENT facilitates the movement of water by OSMOSIS. Osmosis is the process whereby water moves across a semi-permeable membrane from a region of low solute concentration to a high solute concentration.
Based on this osmotic gradient, water moves from the extracellular solution into the cell, causing it to swell and eventually burst as a result of excessive water intake.
Answer:
C
Explanation:
Since the dark green phenotype allows the insects' to blend in with their surroundings, there will be generally more of the same dark green phenotype on the remote island. Since they are blending in with their surroundings, they survive easier, and they are able to stay alive long enough to reproduce. Let me know if this helped!
