Answer:
D. Molecules called pumps function to control active transport.
Explanation:
Active transport is one of the two types of transport (the other being passive transport). It is the type of transport in which substances move against their concentration gradient i.e. from a lower concentration to a higher concentration. Hence, due to this, energy input in form of ATP is required by the cell.
However, the process of active transport makes use of certain molecules called PUMPS to control it. The pumps moves ions/molecules against their concentration gradient. An example is the sodium-pottasium pump which moves sodium ions from a region of low conc. to a region of high conc.
Angiosperm have flowers.It is a flowering plant.
They are able to respond to the presence of invading organisms because they recognize the<u> antigen </u>on the surface of organisms. There are specific receptors on the surface of immune system cells.
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.
