How could you show both the hills and the flat fields on the same map?
Answer:
For the hills, you would have to draw a symbol to symbolize the mountains. Like, you could draw a curved line to represent the hills. Then come up with another symbol for the flat lands, but be sure to do a key, telling which means hills and which means flat fields.

which property of light causes a rainbow to form
Answer:
Refraction
Explanation: Reflection is when light bounces off a medium at an angle back to its source.
Refraction bends light, so when it's transmitted through a prism, light is refracted into the colors of the spectrum.

Which of the following statements is true?
A.
Chemical reactions can only absorb thermal energy.
B.
Chemical reactions can neither absorb thermal energy nor release thermal energy.
C.
Chemical reactions can either absorb thermal energy or release thermal energy.
D.
Chemical reactions can only release thermal energy.
Answer: C. Chemical reaction absorb or release thermal (and sometimes other) energy
Explanation:
Chemical reactions can result in products with more or less chemical energy than the precursors. When products have less chemical energy, the excess is converted to heat (exothermic reaction)
When the products have more chemical energy, heat must be added to make up the difference (Endothermic reaction)
Fireworks are examples of exothermic reactions where the excess is released as thermal, mechanical, and radiant energy. A lit match releases thermal and radiant energy.
Respiration is also an exothermic reaction
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy
Respiration is the reverse of photosynthesis, an endothermic process. The overall photosynthetic reaction is 6CO2 + 6H2O + energy —> 6C6H12O6 + 6O2
In this case radiant energy drives the reaction.
The reaction 2H2O —> 2H2 + O2 is an endothermic reaction driven by electrical energy.
Many reactions are reversible and if one is endothermic, the reverse is exothermic e.g. 2H2 + O2 —> 2H2O +energy is the reverse of electrolysis of water, or respiration vs photosynthesis.

Please answer quick will give you brainliest
Answer:c
Explanation:
Bc
A biome is a major community of plants and animals living in a specific geographic area and adapted to specific climate conditions. There are five major types of biomes: grassland, forest, desert, aquatic and tundra.
These major biomes can be divided into different categories (e.g., temperate grasslands).The grassland is a biome that has grasses as the dominant vegetation.The temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).In these regions (temperate grasslands) rainfall is insufficient to support trees.The temperate grasslands have four well-defined seasons. i.e., spring, summer, fall (autumn), and winter.Some examples of temperate grasslands include Argentine pampas, Euro Asian steppes and North American prairies.In conclusion, the temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).

HELP!Mariana eats an orange. Which statement describes the ultimate source of the energy that her body receives when she digests the orange?
Organic matter, rich soil in which the orange tree grows, and adequate water all work together to generate the energy that can be obtained from the orange.
The orange tree obtains energy from the nitrogen and other compounds in fertilizer.
The light energy that originates from the sun provides the energy to grow oranges, which contain macromolecules.
The orange contains the energy-rich nutrients that it draws from the soil.
Answer:
C.
Explanation:
The light energy that originates from the sun provides the energy to grow oranges, which contain macromolecules.
Please do not be upset if this is wrong.
The ultimate source of energy received by digesting orange is the light energy that originates from the sun provides the energy to grow the oranges, which contain macromolecules. Thus, the correct option is C.
What is the ultimate source of energy?The ultimate source of energy of the solar system is the Sun. It is the primary source of energy for the Earth. The sun is called the ultimate source of energy because it is the source of almost all energies of the earth.
With the help of solar energy, all the green plants (producers) produce food by the process of photosynthesis. In turn, animals eat plants and use the chemical energy for all the activities such as cellular activities.
Therefore, the correct option is C.

Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following?a.producing enzymesb.generating more nerve cellsc.performing cellular respirationd.transporting ions against a concentration gradien
Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.

How many ATP are produced by the ETC?
A) 2
B) 4
C) 12
D) 32
Answer:
The electron transport chain or ETC for short has 34 ATP (Adenosine Triphosphate or the energy carrying molecule) Which has the molecular formula C10H12N5O13P3. So I would go with D because this is closest.
This is because one molecule of glucose in a Eukaryotic cell generates around 30 to 32 ATP.
Explanation:
The 34 ATP produced by ETC(Electron transport chain) or the electron transport stage produces the most ATP(energy carrying molecule) out of any stage in aerobic respiration/ cellular respiration cycle. While the krebs cycle, and Glycolysis produce 2 ATP each. Making the rest of the stages 30 ATP total.

This plate is made up of fused vesicles that contain pectin, hemicellulose, and cellulose. The cell plate grows and turns into the cell wall between the two identical cells.
The motion of objects can be quite complex. The motion of this frog is an example, Suppose that the frog moves from one lily pad to the other in 1 second 1 m Describe the motion of the frog as it makes one round trip between the two lily pads Use the terms speed, velocity, displacement, and distance in your answer
Answer:
The speed of the frog is 1m per second the velocity is he can turn and jump in a different direction in 1 second the distance is 1m and there is no displacement.
( this was not my answer but it’s right. I saw it in the comments)
Explanation:
The speed of the frog is understood to be 1m/sec.and the velocity is that through which a frog can turn and jump in a different direction in 1 sec the distance is 1 m. This returning back to the original position represents no displacement.
What is Displacement?Displacement may be defined as the rate of change in the position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position.
Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s).
Speed may be defined as the rate of change of position of an object in any direction. It is measured as the ratio of distance to the time in which the distance was covered. It is a scalar quantity as it has only direction and no magnitude.
