Answer:
Facilitated diffusion is a type of passive transport of molecules down the concentration gradient between two sides of a membrane which doesn't require ATP and instead uses a specific transmembrane protein.
Active transport requires instead ATP and it is the process drawn in the figure. Moreover the figure illustrates that molecules are moving against their concentration gradient.

Answer:
Female cones contain eggs and produce seeds.
Explanation:
Strobiles, also known as cones, are structures commonly confused with flowers, but should not be so named. Found mainly in gymnosperms, strobiles are responsible for the formation of gametes.
Female cones are larger and more complex than male cones. They have egg scales, spiraling around the strobile axis, and these cones produce seeds. At the time of reproduction, the scales of this cone are well separated, ensuring that pollen grains reach the eggs, germinate and produce the pollen tube, which is responsible for bringing the male gamete to the female. It is these strobiles that will house the seed after fertilization.
Answer:
A flat line
Explanation:
Over time if there is no movement a line would be flat. If you need more clarification please comment and I will help you. :)
Answer: (Aerobic and anaerobic respiration)
Explanation:
Respiration by living organisms can be investigated by carrying out experiments to show the production of carbon dioxide and heat.
Investigating carbon dioxide production
Limewater turns milky in the presence of carbon dioxide. It can be used to show that exhaled air contains more carbon dioxide than inhaled air.
Carbon dioxide dissolves in water to form a weakly acidic solution. Hydrogencarbonate indicator is used to show the presence of carbon dioxide in solution. It is:
red at neutral pH (no carbon dioxide)
yellow at low pH (carbon dioxide present
