single celled organisms are only capable of asexual reproduction.
only cells like the eukaryote can carry out the functions of life.
even primitive cells, like the prokaryote, can carry out the functions of life.

out of; swell or lyse
30s - Q11
The process of keeping the internal environment of the body stable by responding to changes in the external environment is known as homeostasis. Which of the following accurately describes a mechanism for maintaining homeostasis at the cellular level?
Active transport, where molecules are pumped across the cell membrane against the gradient from low to high concentration.
Facilitated transport, where enzymes are used to increase the rate of solvent transfer across a membrane.
Active transport, where the solution is pumped across a membrane to from high to low concentrations.
Passive transport, where ATP is used to facilitate the movement of molecules from high to low concentrations.
30s - Q12
Which of the following would likely move through the phospholipid bilayer the most easily?
starch
CO2
Glucose
K+
30s - Q13
What type of cellular transport requires a cell to use energy?
Diffusion
Facilitated transport
Movement of glucose from an area of high concentration to an area of low concentration
Active transport
30s - Q14
Which of the following statements regarding the movement of molecules across cell membranes is true?
Three examples of passive transport are diffusion, facilitated diffusion, and osmosis.
Polar molecules generally diffuse more readily through the plasma membrane than do nonpolar molecules of the same size.
Water molecules are commonly actively transported out of cells.
In facilitated diffusion, a molecule is moved across a membrane against its concentration gradient.
