The statement is true. Economic profit equals zero when total revenue (TR) equals total cost (TC).
In Economics, total cost is defined as the sum of costs that is incurred by firm for the production of certain level of output.
Mathematically, it is calculated as:
TC (total cost) = TFC (total fixed cost) + TVC (total variable cost)
Fixed cost refers to a cost that does not change with an increase or decrease in the number of goods or services produced or sold.
Variable cost changes with an increase or decrease in the number of goods or services produced or sold.
Total revenue is also called gross revenue. It is the total amount of income your company brings in from selling your products/services.
When total revenue (TR) equals total cost (TC), economic profit equals zero.
Hence, the given statement is true.

Which of the following describes a lysosome
Ducks are aquatic birds. Their feet are webbed and this trait makes them fast swimmers. Biologists believe that ducks evolved from land birds, which did not have webbed feet. How could this have happened
Answer:
Random chance mutations led to the webbed feet trait in ancestral land birds, conferring them an adaptive advantage. Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations.
Explanation:
Mutations are ramdom changes in the nucleotide sequence of the genome of a particular organism. In general, mutations are deleterious, but mutations may occasionally be beneficial in certain environments. A beneficial mutation must be associated with one or more phenotypic traits capable of conferring an adaptive advantage in a certain environment, thereby the individuals carrying the mutation have more chances to reproduce and survive. In this case, one or more beneficial mutations associated with the webbed feet trait passed to the next generations, increasing their frequency in the population.

Which of the following is NOT a function attributed to Glia?
~They prevent toxic substances from reaching the brain.
~They process information going into the neuron
~They eliminate foreign substances inside neurons.
~They provide insulation for axons.
Answer:
~They process information going into the neuron
Explanation:
This is because Glia or neuroglia cells are cells found in the central nervous system that is brain and spinal cord and they did not transmit electrical impulses. Glia cells don't carry information because they don't carry electrical impulses. The cells include epipdymal cells,Schwann cells e.t.c.
They perform four major function and they include; They provide support and supply nutrients and oxygen to the cells,it prevent toxic or foreign substances from entering the neurons,they provide insulation for axons.

Explanation:
Enzymes can be regulated in a multitude of ways. One such way is by covalent modification, in which functional groups are attached to or removed from the enzyme. One such functional group that can be added to an enzyme is a phosphate group. Depending on the enzyme, addition of a phosphate group may increase or decrease that enzyme's activity. Which of the following is the general name of an enzyme that functions to add phosphate groups to its substrate?
a. Oxidoreductases
b. Ligases
c. Hydrolases
d. Isomerases
e. Transferases
Answer:
Option E
Explanation:
Transferase enzyme are able to transfer a molecule or atom from one compound to the other.
For example – In the process of phosphorolysis, add phosphate to the substrate group .
X-Y + Z = X + Z-Y
Here Z in the phosphate group
Hence, option E is correct

define dorsiventral leaf
A dorsiventral leaf, also known as a bifacial leaf, is a type of leaf structure characterized by having distinct upper and lower surfaces with different functions and structures.
The upper surface of a dorsiventral leaf is called the adaxial surface, while the lower surface is called the abaxial surface. The adaxial surface is usually dark green and is exposed to more sunlight, while the abaxial surface is typically lighter in color.
This structural asymmetry allows for efficient photosynthesis on the upper surface while minimizing water loss through stomata on the lower surface.
Dorsiventral leaves are commonly found in dicotyledonous plants and contribute to their overall shape and function in terms of light absorption, gas exchange, and transpiration.

A solution has a pH of 5. If the pH changed to pH 8, which of the following statements is true?
a.The concentration of H+ increased by 3 times.
b. The concentration of H+ increased by 1000 times.
c. The concentration of H+ decreased by 1000 times.
d.The concentration of H+ decreased by 3 times.
Answer:
C. The concentration of H+ decreased by 1000 times.
Explanation:
As pH increases, the concentration of H+ decreases by a power of 10.
The pH level increases 3 times causing the concentration to decrease (10^3).

When energy from the Sun reaches Earth, the energy is not absorbed at the same rate by the air,
the land or the surface. What does the uneven heating of the Earth cause?
Answer:uneven heating of Earth's surface produces wind because the air temperature and air pressure are different. The differences in the air causes the air to a lower pressure. ... Uneven heating of the Earth's surface produces air masses of different temperatures. Cold air sinks, forcing warm air to rise, hope this helps.

Which property of water allows it to dissolve substances like sodium Which property of water allows it to dissolve substances like sodium chloride and glucose but prevents it from dissolving lipids?
A. pH
B. polarity
C. adhesion
D. cohesion
Polarity is an intrinsic property of water associated with its behavior to dissolve substances like sodium chloride and glucose.
What is polarity?It is a property of high importance because it defines the behavior of these related to other properties.
It represents the unequal electrical charges in the same molecule, said unequal splitting of electrons makes water a polar molecule.
Therefore, we can conclude that polarity is an intrinsic property of water associated with its behavior to dissolve substances like sodium chloride and glucose.
