What would happen to the concentrations of
Pyruvate, NADH and intermembrane H+ if the ETC
stopped working?
Answer:
Stay the Same, Increase, Decrease
Explanation:
Glycolysis produces pyruvate which is functioning normally if only the ETC (electron transport) stopped working because the ETC happens AFTER glycolysis, hence pyruvate is being produced and used at a normal rate (no change). NADH is produced in the cellular respiration stage PRIOR to the ETC so it is being created at a normal (or average) rate, however, it is not being used and split properly (meaning, not enough) in the ETC stage hence it's concentration increases. H+ decreases because it cannot be made if the prior step(s) were not complete.
What would happen to the concentrations of pyruvate, NADH and intermembrane H+ if the ETC stopped working are:
Pyruvate would stay the same and not be affected.that is it would remain the same.NADH would increaseH+ in the intermembrane would decrease.The concentration of the Pyruvate would not be affected If ETC stopped working and so this will make NADH would increase. Due to the fact that there is no electrons been transported down the chain, so therefore, no H+ would be moved and this in turn would make the concentration of H+ in the intermembrane space to reduce.Conclusively, we can therefore say that what would happen to the concentrations of pyruvate, NADH and intermembrane H+ if the ETC stopped working are:
Pyruvate would stay the same and not be affected.that is it would remain the same.NADH would increaseH+ in the intermembrane would decrease.Learn more from

Explanation:
I have a huge test tomorrow and I need to know every thing about Cells, like the eukarotic cell, i need to know the cell membrane, and osmosis.
Answer:
look it up or ask your friends to look it upmaybe?
Explanation:
Answer:
Cell Definition“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.”
Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.
Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids. Moreover, cellular structures called cell organelles are suspended in the cytoplasm.
Types of Cells.Prokaryotic CellsProkaryotic cells have no nucleus. Instead, some prokaryotes such as bacteria have a region within the cell where the genetic material is freely suspended. This region is called the nucleoid.
They all are single-celled microorganisms. Examples include archaea, bacteria, and cyanobacteria.
The cell size ranges from 0.1 to 0.5 µm in diameter.
the hereditary material can either be DNA or RNA.
Prokaryotes reproduce by binary fission, a form of sexual reproduction.
Eukaryotic CellsEukaryotic cells are characterised by a true nucleus.
The size of the cells ranges between 10–100 µm in diameter.
This broad category involves plants, fungi, protozoans, and animals.
The plasma membrane is responsible for monitoring the transport of nutrients and electrolytes in and out of the cells. It is also responsible for cell to cell communication.
They reproduce sexually as well as asexually.
There are some contrasting features between plant and animal cells. For eg., the plant cell contains chloroplast, central vacuoles, and other plastids, whereas the animal cells do not.
Functions of Cell:Provides Support and StructureFacilitate Growth MitosisAllows Transport of SubstancesEnergy ProductionAids in ReproductionCell Membrane The cell membrane supports and protects the cell. It controls the movement of substances in and out of the cells. It separates the cell from the external environment. The cell membrane is present in all the cells. The cell membrane is the outer covering of a cell within which all other organelles, such as the cytoplasm and nucleus, are enclosed. It is also referred to as the plasma membrane. By structure, it is a porous membrane (with pores) which permit the movement of selective substances in and out of the cell. Besides this, the cell membrane also protects the cellular component from damage and leakage. It forms the wall-like structure between two cells as well as between the cell and its surroundings. Plants are immobile, so their cell structures are well-adapted to protect them from external factors. The cell wall helps to reinforce this function.What is Osmosis?Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.
Any solvent can undergo the process of osmosis including gases and supercritical liquids.
Osmotic Solutions There are three different types of solutions:An isotonic solution: is one that has the same concentration of solutes both inside and outside the cell.
A hypertonic solution: is one that has a higher solute concentration outside the cell than inside.
A hypotonic solution; is the one that has a higher solute concentration inside the cell than outside.
Effect of Osmosis on CellsOsmosis affects the cells differently. An animal cell will lyse when placed in a hypotonic solution compared to a plant cell. The plant cell has thick walls and requires more water. The cells will not burst when placed in a hypotonic solution. In fact, a hypotonic solution is ideal for a plant cell.
An animal cell survives only in an isotonic solution. In an isotonic solution, the plant cells are no longer turgid and the leaves of the plant droop.
The osmotic flow can be stopped or reversed, also called reverse osmosis, by exerting an external pressure to the sides of the solute. The minimum pressure required to stop the solvent transfer is called the osmotic pressure
Significance of Osmosis Osmosis influences the transport of nutrients and the release of metabolic waste products.It is responsible for the absorption of water from the soil and conducting it to the upper parts of the plant through the xylem. It stabilizes the internal environment of a living organism by maintaining the balance between water and intercellular fluid levels. It maintains the turgidity of cells. It is a process by which plants maintain their water content despite the constant water loss due to transpiration. This process controls the cell to cell diffusion of water. Osmosis induces cell turgor which regulates the movement of plants and plant parts. Osmosis also controls the dehiscence of fruits and sporangia. Higher osmotic pressure protects the plants against drought injury.The proteins found in your hair and fingernails would be classified as what type of proteins?

Describe what needs to occur in order for a metamorphic rock to form.
If your not gonna put a HELPFUL ANSWER, please do not answer, thanks.
Answer:
Any sort of prexisting rock whether sedimentary, igneous, or even metamorphic rock must change under extreme conditions like extreme heat or pressure.
Explanation:
An igneous rock is a rock that has been created via cooling of magma.
A sedimentary rock is formed from sediments, whether they be natural like seashells, or other pieces of older rocks that have worn away. usually formed under pressure.
A metamorphic rock is a rock that's changed, because it was put under extreme pressure or exposed to extreme heat.
Think of the part morphic in the word metamorphic-it literally means that it morphed or that it changed dramatically.
There are two ways for a rock to become metamorphic under extreme pressure or extreme heat. and there are two types of metamorphic rocks, contact metamorphism and regional metamorphism.
Those mean pretty much exactly what they say.

A pair of fruit flies reproduces and has 1000 offspring. All 1000 offspring have the alleles Gg. What is the most likely combination of alleles that each parent has, and why are other combinations not likely.
Answer:
The correct answer would be - GG and gg.
Explanation:
As it is given that all the 1000 offspring having the same allele Gg which is only possible in one condition that is cross between GG and gg because it is a heterozygous condition in the offspring. So there must be both allele present and it can not be heterozygous parents as there would be a different combinations of offspring in that case.
If the parents either GG only all the offspring would be GG the same with gg than all the offspring will be gg, thus the correct answer would be GG and gg.
