2. the carrying capacity is around 24 since that is when they reach population equilibrium.
3. This will lower the mice population since it will introduce a predator that will lower the carrying capacity.
4. The mice population can change in the future if more predators are introduced, if predators die out/go away, if an invasive species is introduced that competes with the mice for resources, if the climate changes, and if the amount of resources available to the mice increases or decreases.

b. because the warmer air allows the particles to be free from gravitational forces
c. because the heat liberates the potential energy inside each molecule eliminate
d. because the warmer air is less dense and particles can move more
Answers
Answer: Option (a) is the correct answer.
Explanation:
When temperature of surrounding atmosphere around the tire increases then it will lead to increase in the kinetic energy of molecules.
Due to increase in kinetic energy of molecules there will be more number of collisions between the air molecules that are present inside the bicycle tire.
Hence, it means heat has been transferred from the surrounding atmosphere to the molecules inside the tire.
Thus, we can conclude that the air molecules inside a bicycle tire speed up as the temperature gets warmer because the heat is transferred to the molecules and gives them more kinetic energy.
B. Impulses have to be sent to the brain through the auditory nerve.
C. The brain has to interpret the direction from which the sounds are being delivered.
D. The outer ear has to collect the sound waves and lead them to the middle ear.
Answers
Answer : Option D) The outer ear has to collect the sound waves and lead them to the middle ear.
Explanation : Hearing is dependent on a series of complex steps that change vibrations of sound waves in the air into electrical signals. At first the vibrations of sound waves gets collected by the outer ear and from there sound waves travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. The auditory nerve then carries these signals to the brain.

Answers
The concentration of a solution can be expressed in (4) moles per liter
Further explanation
Stoichiometry in Chemistry learn about chemicals mainly emphasizes quantitative, such as the calculation of volume, mass, number, which is related to numbers, molecules, elements, etc.
In the reaction there are also manifestations of reagent substances namely gas (g), liquid (liquid / l), solid (solid / s) and solution (aqueous / aq).
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
- Kelvin
Temperature is used as a guide to the level of heat energy from objects
Temperature cannot be measured by the surface of the hand because it is not accurate but can be measured by a thermometer. Temperature units include Celsius, Fahrenheit, Reamur or Kelvin
- milliliters
Volume is a derivative quantity derived from the length
The unit of volume can be expressed in liters or milliliters or cubic meters
- joules per kilogram
Energy can be interpreted as the ability to do work
Energy units can be stated in joules or calories (J or Cal)
- moles per liter
Mole
The mole itself is the number of particles contained in a substance amounting to 6.02.10²³
Mole is the result of dividing the amount of substance mass and its molar mass
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
So to find the number of moles can be expressed as
n = V x M

Telophase because it is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.
