Answer:
If the cell was a city, what would the city have inside it for it to function as a cell?
Explanation:
The cell membrane can be a fence or wall around the city because it controls what enters and leaves the cell, and separates the cell from the outside.
The nucleus could be the city hall because it protects DNA and controls the cell (city)
The mitochondria could be the greenhouse because it makes ATP energy from sugar + 02
The chloroplasts could be a farm or garden because it is where photosynthesis takes place and makes energy + sugar from sunlight
The ribosomes could be the factory to make stuff because it makes proteins
The endoplasmic reticulum could be a kitchen or restaurant because it helps finish proteins, and makes membranes.
The golgi apparatus could be the postal office because it finishes packages and ships proteins
The vacuoles could be a water tank because it storages water
I hope this helps. It is basically as if something was turning into a city-type thing. Like Lysosome could be a recycling center in a city.

As the warmer material rises, it also cools, eventually pushed aside by warmer rising material and sinking back toward the core. Mantle material flows slowly, like thick asphalt or mountain glaciers.

How much heat is necessary to 20g of water at 100*C into steam at 100*C?
Answers
Answer:
To convert 100.0 g of water at 20.0 °C to steam at 100.0 °C requires 259.5 kJ of energy.
The amount of heat which is required for a phase change of a substance without any change in temperature is known as latent heat. Here the amount of heat required is 10,800 calories.
What is heat capacity?The heat capacity of a substance or a system is defined as the amount of heat required to raise its temperature through 1°C. It is denoted by C. The specific heat capacity is the amount of heat required to raise the temperature of 1 gram of the substance through 1°C.
The equation to calculate the heat required is:
Q = mc (T₂ - T₁) + mL₁
L = Latent heat of vaporization of water
m = mass
c = specific heat capacity
T₂ = Final temperature
T₁ = Initial temperature
T₂ - T₁ = 100 - 100 = 0°C
Q = 20 g × 1 cal /g°C × 0°C + 20 g × 540 cal/g
Q = 10,800 calories
Thus the amount of heat required is 10,800 calories.

CFCs (or halocarbons) are ____ - _____ (range) times as powerful a GHG as CO2.
A) 1,000 - 15,000
B) 2,000 - 25,000
C) 5,000 - 65,000
D) 500 - 5,000
Answers
CFCs are 1000-15000 times powerful as compared to greenhouse gas such as CO2.
Chlorofluorocarbons are present in less amount or less abundant than carbon dioxide gas in the atmosphere but they are 10,000 times more powerful as a greenhouse gas.
These CFCS gases can remain in the atmosphere for more than 45 to 100 years. CFCS gases greatly damaged the ozone layer by reacting with it that leads to increase in the diseases such as skin cancer so we can conclude that CFCs are more powerful as compared to carbondioxide gas.

d. Electrons lose energy as they travel around the nucleus
e. Each energy level has a specific energy value
Answers
The model of Neils Bohr postulates that electrons in atoms are found in specific energy levels. Transition from a higher to a lower energy level produces an emission spectrum characteristic of elements.
According to Bohr's model of the atom, an electron in atom exists in distinct energy levels. Electrons can be promoted from lower to higher energy levels when they absorb energy. The electrons are unstable in this higher energy excited state hence they quickly return to the ground state emitting energy. This emission is characteristic of elements.

If an ionic compound has a 2- charge how does that affect the total number of electrons in a Lewis structure
Answers
In the situation where an ion has a charge of -2, the Lewis structure is affected because it must add two additional electrons.
The Lewis structure is a term to refer to the graphical representation that shows the pairs of electrons in dashes or points of bonds between:
The atoms of a moleculeThe lone electron pairs that may existAdditionally, the charge of an ionic compound is calculated using the difference in electrical charge between the electrons. On the other hand, an ion is formed by adding or removing electrons, so the magnitude of the resulting charge depends on the number of electrons added or removed.
According to the above, if an ionic compound has a -2 charge, the Lewis structure must add two electrons.

g. What is the density of the oil?
Answer in a complete sentence. Show your work. Your final answer should have the cor-
rect number of sig figs. show work!
Answers
Answer:p=m/v
p=(292.2-130.2)/200
p=0.8100g/ml
Explanation:
Density of a substance is the ratio of its mass to volume. The density of the oil filled in a 200.01 ml beaker is 0.815 g/ml.
What is density?Density of a substance is the mass per volume. Thus we het how much of its particles are located per one unit of volume.
Mathematically density can be written as mass/ volume. The mass of the beaker containing oil is given as 293.2 g. The mass of beaker itself is 130.2 g. Hence, mass of oil is 293.2 - 130.2 = 163 g.
Volume of the oil is 200 ml. Thus density is 163 g/200 ml = 0.815 g/ml.
Hence, the oil in the beaker with 200 ml volume and 163 g mass have a density of 0.815 g/ml.
