Maintaining an internal body temperature is one of the key components to maintaining homeostasis. ____________________ involves

cooling the body down by bringing more blood to the capillaries on the surface of the skin where the heat can be lost. ___________________ involves shutting down those capillaries so less heat can be lost and the body can warm.

15. When there is light, plants do which of the following biological<br> processes?<br> *
zhuklara [117]

Answer: Plants do both photosynthesis and cellular respiration.

Explanation:

All cells do cellular respiration even without light.

Honestly, photosynthesis alone would be right since the teacher didnt  state the questions correctly. But you should choose both cause in the light it does both.

8-2 Telling Them Apart. From the following list of properties, indicate which one(s) can be used to distinguish between each of
Oksanka [162]
<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

Which is a tough and flexible layer that surrounds plant cells, as well as some algal and bacterial cells?
Vika [28.1K]


This layer is called the cell wall.

The cell wall is located outside the cell membrane and provides the cells with structural support and protection.  It gives cells rigidity and strength, offering protection against mechanical stress.

In most cells, it is flexible, meaning that it will bend rather than hold a fixed shape, but has a lot of tensile strength which is necessary to be able to withstand internal osmotic pressure.

Cell walls are found in plants, bacteria, fungi, algae and some archaea.
