Answer:
The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.

Suppose a particular glacier covers 100 km2, and it loses 30 cm of depth in a decade. Approximately what volume (km3) is lost? Show your work.
Answer:
0.03 km^3
Explanation:
First convert the 30 centimeters into kilometers. This will give you 0.0003 km because 1 km is 100,000 cm. Next multiply 100km^2 by 0.0003km which will give you your answer or 0.03 km^3.
Approximately 0.03 km^3 volume (km3) is lost.
How can we calculate the mass from density and volume?Density is defined as the mass per unit volume it means that mass present in 1 meter cube is called density. The S.I unit of density is kg/m^3 and in C.G.S it is gram/cm^3
So, In above question can understand that density, mass, and volume all are convert to each other it means that if we know any two variable then third one will be calculated easily.
If we want to acceleration in an object then we must apply a force on a object to give motion so we can say that we required to do work for acceleration and then we can say that required is equal to kinetic energy.
Mathematically,
Formula for density will be as mentioned below:-
Density = Mass/Volume.
From above formula we can calculate mass which is as follows:-
Mass = Volume × Density.
S.I unti of mass is kilograms and C.G.S unit is gram.
Therefore,Approximately 0.03 km^3 volume (km3) is lost.

When the levels of greenhouse gases in Earth's atmosphere increase, which statement is true? Earth's temperature increases because Hin increases. Earth's temperature increases because Hout increases. Earth's temperature increases because Hout decreases. Earth's temperature increases because Hin increases and Hout decreases.
Answer:
Earth's temperature increases because Hout decreases.
Explanation:
The statement 'Earth's temperature increases because the heat that out the Earth (Hout) decreases' is TRUE.
Greenhouse gases are gases that absorb the heat energy from the Earth's surface and reradiate this heat back to the Earth's surface, thereby increasing the temperature of the Earth's planet by a greenhouse effect.The most important greenhouse gases include carbon dioxide (CO2), methane, and vapor of water (H2O).It has been shown that these gases (greenhouse gases) are progressively and irreversibly increasing the temperature on the Earth's surface.In conclusion, the statement 'Earth's temperature increases because the heat that out the Earth (Hout) decreases' is TRUE.

How would holding your breath impact the cellular processes that are taking place in your muscles
Holding your breath has a variety of effects on the biological processes that occur in our muscles.
When you hold your breath, you're doing an anaerobic workout instead of an aerobic one.
Your muscles absorb oxygen from the atmosphere and burn it during aerobic exercise. Because your body can't accomplish that while you're anaerobic, your muscles produce lactic acid, which causes muscular soreness.

Between 1915 and 1945, the United States went through World War I, the booming 1920,
the Great Depression of the 1930, and World War II. Although this time period was traumatic for many Americans, it also transformed the US identity. Think of the 1920 in contrast with the Great Depression of the 1930. Which of these two time periods do you think has had a bigger impact on the development of US society, either from a political or cultural viewpoint? Explain why.
Answer:
Well, I think the Great Depression had a major impact on the development of American society mainly from a political point of view. There was financial panic and it was very difficult for American citizens because most of the people lost everything they had. Jobs, money, cars, and homes were some of the many things they lost during the 10-year Great Depression. This changed everything politically speaking because the people began to get demoralized and did not trust the government.
