Do you think people use energy before modern times why or why not
Answer:
Yes
Explanation:
Before the modern times, energy consumption was vital in order to survive. For example, you need heat (thermal energy) to cook food and also be in a decent state of temperature for your body. If they had be never used energy, the generations wouldn't go on. Energy is our main source of living. Solar energy provides sunlight to plants so they can be grown healthily to provide nutritious fruits and vegetables.
To conclude, yes, people did use energy before the modern times otherwise, they would've not survived.
Before the manufacturing revolution, our energy demands were mediocre. For heat, we relied on the sun. Whenever the sun disappointed us, we scorched wood, hay, and withered dung. Our society's energy use changed forever, even with the low-cost automobile and the expanse of electricity. Energy usage increased rapidly, doubling every decade. The price of energy production was decreasing unwaveringly, and the efficient use of energy was not a concern. Drivers lined up at gasoline stations to purchase gas, and President Jimmy Carter went on television to announce that energy preservation was "the moral equivalent of war." New factory orders had already stopped because of multibillion-dollar price overruns, soaring-high inflation, and a slowdown in electricity demand growth due to the early effects of energy preservation. So I think people used energy before modern times.

A group of students is doing an experiment where they roll a ball down a
ramp and then measure how far across the floor it rolls. The factors that are
the same each time are: - the ball - the ramp, including its length and angle
to the surface - where on the ramp the ball starts from The students do
change the type of surface the ball rolls on. What is the independent
variable in this experiment? *
ramp
ball
distance
type of surface the ball rolls on.What is the independent variable in this experiment
Answer:
The Ramp.
Explanation:
You don't move the ramp, the ramp isn't dependent on the ball or the distance.
The distance depends on the ball and ramp
the ball depends on the ramp

what is the main purpose of WBC in blood platelets
Answer: You can consult:
They protect you against illness and disease. Think of white blood cells as your immunity cells. In a sense, they are always at war. They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health.
Explanation:
I'm not sure but hope it helps.
Answer:
Explanation:
The cellular portion of blood contains red blood cells (RBCs), white blood cells (WBCs) and platelets. The RBCs carry oxygen from the lungs. The WBCs help to fight infection, and platelets are parts of cells that the body uses for clotting.White blood cells are part of the body's immune system. They help the body fight infection and other diseases. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).
How can water-holding capacity of soil be improved?
O Increasing irrigation on the soil
O Reducing drainage on soil surface
O Tilling soil
Adding compost or organic matter to the soil
Answer:
Soil organic matter (SOM) is another factor that can help increase water holding capacity. Soil organic matter has a natural magnetism to water. If the farm increases the percentage of soil organic matter, the soil water holding capacity will increase. SOM is decayed material that originated from a living organism.

define terms organic molecules and inorganic molecules
Answer:
Organic molecules are molecules that have non-carbon atoms inside them. And, Inorganic molecules are molecules which don't consist of any carbons at all, unlike organic molecules.
Answer: Organic molecules contain carbon particles in them but inorganic molecules have no carbon particles in them
Explanation: In organic molecules they contain a carbon-hydrogen bond mostly found or created in humans or living organisms but inorganic molecules contain none of them.
Organic molecules are molecules which are able to decompose due to what they contain e.g carbohydrates.....
inorganic molecules cant decomposes because they contain no carbon -hydrogen bond.

What is the overall net gain of ATP in cellular respiration per one molecule of glucose? between 0-10 between 10-20 between 30-40 between 40-50
Answer:
C 30-40
Explanation:
The overall net gain of ATP in cellular respiration per one molecule of glucose is - between 30-40 (aerobic respiration)
In aerobic respiration, macromolecules such as glucose break in the presence of oxygen to produce energy. That occurs in mitochondria. The stages of aerobic respiration are glycolysis, the Krebs cycle, and ETS.
Glycolysis is the first stage of cellular respiration that is a metabolic pathway of glucose that takes place in the cytosol. Here, the glucose molecule converts into two molecules of pyruvic acid or pyruvate that forms ATP and NADH as energy.
In glycolysis - six ATP molecules are produced.The citric acid cycle is the second stage where In the citric acid cycle, two molecules of ATP are produced.Oxidative phosphorylation of cellular respiration that produces FADH₂ two and eight NADH molecules that produce ATP.=> Two ATP molecules = one molecule of FADH₂ and, therefore, the number of ATP produced from 2 FADH₂ - 4 ATP.
=> NADH = ATP molecules by each molecule and therefore the number of ATP produced from 8 NADH - 24 ATP.
=> The number of ATP produced from the one glucose molecule under aerobic respiration is given as follows:
From glycolysis = 6 ATP
From citric acid cycle = 2 ATP
From FADH₂ = 4 ATP
From NADH = 24 ATP
total 36 ATPs.
Thus, under aerobic respiration 36 molecules of ATP are produced from one molecule of glucose thus, the correct answer would be - between 30 - 40.
