Answer:
1:Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the only force acting on the object is gravity
2:Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
3:A scientific theory is an explanation of something in the natural world that is based on past observations and evidence.
4:In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
Explanation:
Order the following steps in the pyruvate dehydrogenase reaction. The answer is scored as ALL OR NOTHING, so all steps must be in the correct order for credit.
a) Pyruvate and thiamine pyrophosphate react form hydroxyethyl-TPP. CO2 is released.
b) The reduced coenzyme bound to PDH is reoxidized using electrons from FAD.
c) An acetyl group is added to a coenzyme bound to PDH, forming acetyl-dihydrolipoamide.
d) The acetyl group is transferred to CoA, forming acetyl-CoA.
e) Electrons from FADH2 are transferred to NAD+ forming NADH and H+.
Answer:
The correct order is:
1.- pyruvate and thiamine pyrophosphate react form hydroxyethyl-TPP, CO2 is released
2.- an acetyl group is added to a coenzyme bound to PDH, forming acetyl-dihydrolipoamide
3.- the acetyl group is transferred to CoA, forming acetyl-CoA
4.- the reduced coenzyme bound to PDH is reoxidized using electrons from FAD
5.- electrons from FADH2 are transferred to NAD+ forming NADH and H+
Explanation:
Pyruvate reacts with thiamine pyrophosphate (TPP) on the complex enzyme pyruvate dehydrogenase (E1). This process cleaves CO2 and generates acetaldehyde bound to TPP or hydroxyethylamine. E2 is Dihydrolipoyl-transacetylase and has Lipoamide attached. In the transfer from E1 to E2, the hydroxyethyl is oxidized to acetyl, at the same time that the disulfide bridge of the lipoamide is reduced to dihydro-lipoamide, although as this is acetylated, the product is acetyl-dihydrolipoamide. Acetyl group of acetyl-lipoamide (thio-acyl bond) is transferred to CoA-SH, to form Acetyl-S-CoA (thio-acyl bond).Acetyl-CoA is released into the mitonchondrial matrix. Lipoamide is reduced as Dihydro-lipoamide. The last reaction is catalyzed by dihydrolipoyl dehydrogenase, where it is reestablished in the disulfide bond of lipoamide to make it reactive again. For this, FAD is used as an intermediate, which is reduced to FADH2 and oxidizes the sulfides (which are then linked again). Finally, FADH2 reacts with NAD, which is reduced to NADH and H+ released, restoring FAD for a new reaction.

The substrate molecules are entering the cells, so no product is made yet As the substrate is used up, the rate decreases (the slope is less steep)
The line is flat because no new substrate remains and thus no new product appears
There is sufficient substrate, so the reaction is proceeding at a maximum rate
Section A Section D
Answer:
The substrate molecules are entering the cells, so no product is made yet.
There is sufficient substrate, so the reaction is proceeding at a maximum rate
As the substrate is used up, the rate decreases (the slope is less steep)
The line is flat because no new substrate remains and thus no new product appears
Explanation:
First the substrate molecules enters in the cell and no product is produced because the reaction is not started yet. When the reaction starts, the substrate is in large amount while on the other hand, the amount of product is low. As the reaction proceed forward, concentration of substrate is lowering and concentration of product is increasing. When all the substrate used up, so no new product is formed.

When is osmosis used by
cells to move water across a selectively permeable
membrane?
A. Osmosis is used by cells when large molecules pass freely across the selectively permeable membrane.
B. Osmosis is used by cells to create equilibrium when large molecules can't pass through the membrane.
C. Osmosis is constantly in process inside of a cell, regardless of equilibrum.
Answer:
B.
Explanation:
Osmosis moves water from the part of the membrane with less solutes to the part with more solutes. This will continue until the cell or whatever it is reaches equilibrium.
What step occurs in the cristae?
The crista of mitochondria, formed by invaginations of the inner mitochondrial membrane, is where oxidative phosphorylation occurs.
What is mitochondria?Mitochondria are cell organelles that generate the maximum of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).
The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).
The crista of mitochondria, formed by invaginations of the inner mitochondrial membrane, is where oxidative phosphorylation occurs.
Thus, the process name is oxidative phosphorylation.

As arizona poppy plant carries out photosynthesis, which of the following would not occur during stage 1 of the process?
Answer:
a
Explanation:
As arizona poppy plant carries out photosynthesis, Glucose is created using carbon dioxide. The Arizona poppy is a plant indigenous to the American Southwest.
What is photosynthesis ?Photosynthesis is a process that plants and other organisms used to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.
Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis. Water is oxidized within the plant cell, which means it loses electrons, whereas carbon dioxide is reduced, which means it gains electrons. This converts water to oxygen and carbon dioxide to glucose.
Photosynthesis is the process by which carbon dioxide and water are converted into oxygen and glucose. The plant consumes glucose as food and produces oxygen as a byproduct. Cellular respiration is the process by which oxygen and glucose are converted into water and carbon dioxide.
Thus, As arizona poppy plant carries out photosynthesis, Glucose is created using carbon dioxide.

What are the energy producing organelles and under what conditions do they produce energy
Answer: mitochondria are the site of aerobic respiration, for which of course, they require oxygen.
Explanation: mitochondria are the site of aerobic respiration and energy production for which they require a supply of oxygen
The energy-producing organelle is the mitochondria, and the mitochondria make the energy in the aerobic cellular respiration where the cell uses oxygen and makes the energy that is the ATP.
What is the function of the mitochondria?The mitochondria are cellular organelles in which energy is produced, which happens when the cell gets enough oxygen and the glucose is broken down completely to form ATP. The ATP is formed due to the proper oxygenation of the glucose, and the proton gradient is formed. The proton gradient gives the energy to the cell for energy production, and the energy is used by the cell for the overall body metabolism and growth.
Hence, the energy-producing organelle is the mitochondria, and the mitochondria makes the energy in the aerobic cellular respiration where the cell uses oxygen and makes the energy that is the ATP.

Describe: Four examples of renewable resources are featured in the Energy Conversions Gizmo. These resources are produced all the time, so they will not run out. Read about each energy source, and then explain how each is produced in your own words.
Answer:
Explanations below
Explanation:
A. Wind power:
In the principle of wind power energy, the wind turbine used in the process has blades that look like propeller. When the wind turns the blade around a rotor, it spins a generator and electricity is being generated.
B. Water power (also called hydroelectricity):
The hydro power process is similar to that of the wind power. At the hydropower plants in different localities, one would notice the flow of water through a pipe, which turns the blades in the turbine, to spin a generator and electricity is being produced.
C. Solar power:
In solar power generation, solar panels are used. The required solar energy is produced when sunlight strikes the solar panels and that converts the solar power into electricity that can be used.
D. Ethanol:
Ethanol is a renewable biofuel which can be made from different things such as grasses, corn cobs and stocks, rice straw, sawdust, and wood chips. During the process, yeast is used to ferment the start and sugars in the corn and sugar cane. The starch is fermented into sugar which can also be fermented into alchohol [ethanol].
