32. 8) What type of solution has an equal concentration of substances on both sides of the membrane?
A. osmosis
B. hypotonic
C. isotonic
D. Otonic
D. hypertonic
Answer:
C. isotonic
What is a isotonic solution?
Two solutions exerting the same osmotic pressure over a semipermeable barrier are said to be in an isotonic solution. Without affecting the concentration of solutes on either side, this condition enables unrestricted passage of water over the membrane.
What is osmosis?The tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.
Monomers are single organic
compounds that can link together to
form larger compounds.
What are the lipid monomers?
A. fatty acids and mitochondria
B. fatty acids and ATP
C. fatty acids and glycerol
D. fatty acids and DNA'
Monomers are molecules of simple structure that compose the polymers. Option C. fatty acids and glycerol.
What are monomers?
Monomers are the basic unit of polymers. When many monomers join through chemical bonds they form a polymer.
There are many types of monomeric molecules. To name a few, we can mention
Monomer Polymer
• Monosaccharide ⇒ Carbohydrates
• Fatty acid ⇒ Lipids
• Amino acid ⇒ Proteins
• Nucleotide ⇒ Nucleic acids
Monomers are organic molecules of reduced molecular mass and relatively simple, defined structure.
Monomers are composed of carbon, oxygen, and hydrogen atoms, which establish covalent bonds.
In the case of lipids, fatty acids and glycerol are the composing monomers.
Lipids have a hydrophilic head composed of glycerol and hydrophobic tails composed of fatty acid chains.
The correct option is C. The lipids monomers are fatty acids and glycerol.

2. Explain why low carbohydrate diets cause a los of fat. You must describe how aerobic cellular
respiration works in your body when you answer this question.
Low carbohydrate diets cause a loss of fat because it leads to the process called ketosis associated with burning stored fats for energy.
What is cellular respiration?Cellular respiration is the main process by which cells obtain energy by synthesizing ATP, which is mainly achieved by burning glucose (carbohydrate) molecules.
Low carbohydrate diets lead the body to a process known as ketosis where fats are converted into ketones that act as good respiratory fuels.
In conclusion, low carbohydrate diets cause a loss of fat because it leads to the process called ketosis associated with burning stored fats for energy.

Carbon fixation occurs in the second stage of photosynthesis, during the light-independent reactions of the Calvin cycle. In the first step of this cycle, the enzyme Rubisco adds CO2 to the energy-rich compound ribulose 1,5-bisphosphate, ultimately producing two molecules of 3-phosphoglycerate. In a culture of green alga that is carrying out photosynthesis in the presence of CO2 in the laboratory, what would happen to the levels of ribulose 1,5-bisphosphate and 3-phosphoglycerate in the minutes after the lights were turned off and the cultures were plunged into darkness
Ribulose 1,5-biphosphate will be depleted while 3-phosphoglycerate will accumulate.
Carbon fixationThe first step of the carbon fixation during which Rubisco adds CO2 to Ribulose 1,5-biphosphate to produce 2 molecules of 3-phosphoglycerate requires energy molecules from the light reaction.
In the subsequent steps, Ribulose 1,5-biphosphate is regenerated in a step that requires energy molecules from the light reaction.
Thus, in the first few minutes of turning off the light, the available energy molecule from the light reaction will be used up to produce 3-phosphoglycerate. However, the regeneration of Ribulose 1,5-biphosphate will become impossible.

© D.
it uses the Doppler effect to raise trie pitch of sound waves so objects in distant space can be he:
Answer : (A) "It reflects waves off of objects, measuring the difference of the waves it sends and receives".
Explanation :
In Doppler radar system, radio waves emitted from an antenna. It gives information about the motion of targets and their position.
Phase change between a transmitted wave and received echo is calculated using Doppler radar system.
It also gives radial velocity i.e. velocity in the direction of radar. If the phase shift is positive this means the motion is toward the radar and if the phase is negative this implies the motion is away from the radar.
So, the correct option is (A) "It reflects waves off of objects, measuring the difference of the waves it sends and receives".
