The answer is a.Tapeworms living in a mammal's intestinal tract
1. Osmosis
Recall that osmosis specifically refers to <em>water specifically</em> moving through a membrane in and out. In this case, water is moving out of cells through the cell membrane into the water.
2. Diffusion
Diffusion is the movement of molecules according to a concentration gradient. Because of this, diffusion is a form of passive transport because it does not require energy. In this case, oxygen is moving freely from the lungs into the bloodstream. This process does not take energy, and because oxygen is a small, non charged molecule, it can diffuse freely, therefore the process is diffusion.
3. Active Transport
The sodium pump is a prime example of active transport. Remember that when pumps are involved, it essentially means whatever is moving cannot move by itself, but rather needs force behind it, which is provided by the pump. Because sodium cannot simply move out of a nerve cell, this is a form of active transport.
Hope this is helpful!
I believe the answer is cell division, I hope this helps. Let me know if my answer is correct, I’d like to know.
Answer:
c.
The rows of bushes
Explanation:
<em>The experimental unit in this experiment would be the rows of bushes in the field.</em>
<u>By definition, experimental units are considered physical entities that can randomly be assigned to varied treatment regimes during the course of a research.</u>
In this case, the entity that are given different treatment condition during the process of experimentation are the rows of berry bushes within one of the several fields. Half of the rows were covered with nets while the remaining half were left uncovered.
<em>The rows were given different treatments and hence, considered the experimental units in this particular experiment.</em>
The correct option is c.
