How does knowing its own history provide a group with a sence of unite
ozzi
Knowing one's own history provides a group with a sense of unity as it unites them to know how their past brought them together through their past hardships. 

It brings a sense of unity as people can feel they share a history together and have something to relate to, sort of like a nationalistic feeling in a sense.

Therefore, knowing one's history provides a group with a sense of unity as it allows them to feel as though they have something to relate to and have a past that makes them them, in a sense.

Hope this helps!

Predict how a fish's behavior would change if it had an open circulatory system instead of a closed circulatory system
o-na [289]

Since the blood does not return to the heart after flowing through the gills, pressure is not regenerated within the system before it flows to the systemic circulation (the rest of the body). A single circulation would experience a loss of pressure after flowing through the gas change organs (gills of a fish) due to the high cross-sectional area presented by the capillaries of the gills. For ectotherms like fish, this is efficient enough to support their activity level. A fishes behavior would change in a few ways if it had an open circulatory system. However, the most common would be the fish would become extremely active.

Interpret the model. Drag "True" or "False" to the end of each statement. ResetHelp True False The two lines on the outside of t
Aleonysh [2.5K]

(see attached image)

Answer:

  1. The two lines on the outside of the chloroplast indicate a double membrane: True
  2. The Golgi apparatus is not shown in this cell but this does not mean that this organelle does not occur in the cell: True
  3. The relative dimensions and placement of the membranes and organelles in this model are exact representations of those structures in a living cell: False
  4. The large structure in the center is a nucleus: False
  5. This cell is capable of photosynthesis: True

Explanation:

  1. Chloroplast, like mitochondra, have double membrane called the chloroplast envelope. Hence the first statement is true.
  2. Golgi apparatus is found in all plant and animal cell. It is usually located close to endoplasmic reticulum. Hence this statement is true.
  3. The relative dimensions and placement of the membranes and organelles in this model are not an exact representation of those structures found in living cell. Hence its a false statement.
  4. The large structure in the centre is vacuole and not nucleus. Hence its a false statement.
  5. Since its a plant cell so it is capable of photosynthesis. Hence its a true statement
