Why do we see plants as differnet colors?

Biology
1 answer:
sweet [91]3 years ago
5 0
A plant can only use the light energy that it absorbs. The color that we see when we look at a plant is due to the wavelength that are reflected off the surface of the plant.

How does a food chain model energy flow ?
coldgirl [10]
Food chains model energy flow through an ecosystem. Producers pump energy into an ecosystem from an environmental source, and this energy is then passed from one organism to the next.

<h2>Transportation across the membrane</h2>

Explanation:

(a) Simple diffusion; Faciliated diffusion-Directions in which two transported solutes move

  • In simple diffusion diffusion of non polar compounds across the membrane and along the concentration gradient without the involvement of protein whereas in case of facilitated diffusion membrane transport proteins that facilitate movement pf molecules across the membrane down its concentration gradient
  • Both the diffusions does not require energy

(b) Facilitated diffusion; active transport-Direction the solute moves relative to its concentration gradient

  • In facilitated diffusion membrane transport proteins that facilitate movement of molecules across the membrane down its concentration gradient without the expenditure of energy
  • Active transport drives transportation of solute against the concentration gradient across the membrane

(c) Simple diffusion; Active transport-Directions in which two transported solutes move and Direction the solute moves relative to its concentration gradient

  • In simple diffusion diffusion of non polar compouds across the membrane and along the concentration gradient without the involvement of protein and energy
  • Active transport drives transportation of solute against the concentration gradient across the membrane;secondary active transporters coupled with transportation of two solute molecules

(d) Direct active transport; Indirect active transport-Direction the solute moves relative to its concentration gradient or its electrochemical potential

  • Direct active transport use direct energy such as ATP hydrolysis,oxidation and sunlight energy
  • Indirect active transport use indirect energy such as chemical gradient,electrochemical gradient established by direct active transporters;one solute moves along the concentration gradient while other moves against the concentration gradient

(e) Symport; Antiport-Direction in which two transported solutes move

  • In symport both the solute molecules move in same direction;coupled with primary active transport(direct transport)
  • In antiport both the solutes moves in opposite direction;coupled with secondary active transport(indirect transport)

(f) Uniport; coupled transport-Directions in which two transported solutes move

  • Uniport is the transport of single solute across the membrane
  • Coupled transport is the transport of two solute molecules across the membrane;it may be symport or antiport

(g) P-type ATPase; V-type ATPase-Kinetics of solute transport

  • P-type ATPase always transport cations and undergoes phosphorylation
  • V-type ATPase(here V stands for vacuole) transport protons and no phosphorylation occurs;catalytic activity is not reversible
  • Both are types of primary active transporters

Click and drag each label to the accurately identify the components of the visceral baroreflex
QveST [7]

The right answers are on the attached image.


Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.

As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.

Which ligaments prevents the tibia from sliding forward in the knee joint?
Vladimir79 [104]

Answer: Anterior cruciate ligament

Explanation:The anterior cruciate ligament (ACL) connects the front of the tibia to the back of the femur. It keeps the tibia from sliding forward and limits its rotation. The posterior cruciate ligament (PCL) keeps the tibia from sliding backward. The patella ligament helps secure the patella over the front of the knee joint.
