Answer: The correct answer is: C The are the same except osmosis specifically and only involves water.
Explanation:
Osmosis is the process in which a solvent moves across a semipermeable membrane in order to dilute a concentrated solution and it ends up equalizing the concentration of the solution at both sides of the cell membrane.
On the other hand, diffusion occurs when particles move from an area of higher concentration to an area of lower concentration and it ends up equalizing the concentration.
So the main difference is the presence/ Lack of water in the processes.
In conclusion the correct answer is : C.

describe how an amino acid molecule passes from the lumen of the ileum to the liver
Answer: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides.
Explanation: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides. They are then transported across the alabaster membrane via facilitated diffusion. Di and tripeptides are absorbed via separate H+ dependent cotransporters and once inside the cell are hydrolyzed to amino acids.
Amino acid molecule passes from the lumen of the ileum to the liver
through Sodium cotransporter.
The protein first of all hydrolyzed into amino acids through the enzymes
gastric and pancreatic proteases.
Amino acids are absorbed from the lumen of the ileum to the liver through
the cotransporter. This is done by it moving through the alabaster
membrane through the mechanism called facilitated diffusion and
subsequent absorption through H+ dependent cotransporters.

how is Lysosomes are formed
Answer:
lysosome formationLysosomes form by budding off from the membrane of the trans-Golgi network. Macromolecules (i.e., food particles) are absorbed into the cell in vesicles formed by endocytosis. The vesicles fuse with lysosomes, which then break down the macromolecules using hydrolytic enzymes.

Answer:
I think the answer is Convection but I'm not sure
Explanation:
Observations from plant breeding and animal husbandry over thousands of years has shown:
variations are limited to the confines of a particular taxon
step by step transitions between divisions or phyla have occurred
variation is the result of evolution from one species to another
observable changes from one basic kind into another have never been documented
Answer:
The correct answer is -
variations are limited to the confines of a particular taxon (only if is is lower taxa)
observable changes from one basic kind into another have never been documented
Explanation:
The higher will be the taxa the lesser the effect of the variation takes place so the variations are often limited to the confines of lower taxa. Higher taxa show the difference from other organisms if the huge changes take place due to the set of variations.
As this is a method that is not supposed to be part of ongoing researches so, such observable changes that take place due to the variation have never been documented.
Thus, the correct answer is - 1 and 4 statements.
Analyze how osmosis affects the size of the cell when placed in either an isotonic, hypotonic or hypertonic solution.
Discuss the direction of the movement of water across the cell membrane for each situation above and how this affects cell size.
Explanation:
Osmosis is defined as the movement of water from a LOW concentration of solute to a HIGH concentration of solute.
Isotonic means that both the solution (environment of the cell) and the inside of the cell have equal concentrations. Now, it is important to know that even though they may have similar concentrations, there may be different solutes inside or outside of the cell.
Hypertonic is when one solution (either the inside of the cell or the outside) has a higher concentration of a certain solute
Hypotonic is the solution that has the less concentration of a certain solute.
If the inside of the cell has more solute than the outside, then the water will move inside the cell, make it bigger, and eventually make it burst.
If the outside of the cell has a higher concentration of a solute, the water inside the cell will move out of the cell and go to the environment. This will cause the cell to shrink in size.
If both the outside and inside of the cell have the same solutes at the same concentration, then the two are said to be isotonic, and the cell will keep its normal shape.
What forms at a convergent plate boundary?
Answer: Usually, one of the converging plates will move beneath the other, a process known as subduction.
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.

Answer:
The statements which are indicative of a covalent bond are as follows -:
Electron movement is concentrated somewhere between the two bonded nuclei.The greatest probability of finding the shared electrons is in the area of orbital overlap.The valence electrons involved in the bond are moving solely around the nucleus of the atom with the higher electron affinity.Explanation:
Among the given four statements, three statements are correct, the statement- "Electron density is focused on one element in the bond, generally resulting in the formation of a crystalline substance." is incorrect as In ionic bonds, crystalline formation takes place.
Somewhere between the two bonded nuclei, electron movement is centered. --: Covalent bonds are a class of chemical bonds in which valence electrons are shared between two atoms, typically two non-metals. The formation of a covalent bond helps the non-metals to obey the octet 's law and thus become more stable.The greatest probability of finding the shared electrons is in the area of orbital overlap.-: A pi bond (π bond) is a type of covalent bond arising from the overlap of two p orbitals side by side.The valence electrons involved in the bond are moving solely around the nucleus of the atom with the higher electron affinity.- : As pairs of electrons are exchanged by atoms, covalent bonding happens. In order to achieve further stability, which is gained by forming a complete electron shell, atoms can covalently bond with other atoms. Atoms can fill their outer electron shell and achieve stability by exchanging their outermost (valence) electrons.Hence , the correct option is D (I,II and IV )Pls help asap!!!

Bats, birds, and humans are vertebrates. Birds and bats have wings that help them fly, and humans don't have wings. But if you looked at the bone structure of all three organisms, you'd notice similarities in the arrangement of their bones. What can you infer from this information?
Answer:
The correct answer is: Bats, birds, and humans share a common ancestor.
Explanation:
By observing the similarities between bats, birds and humans one can infer that according to the theory of evolution proposed by Charles Darwin, humans, bats and birds indeed share a common ancestor due to the similarities in the arrangement of their bones.
If bats, birds and human didn't share a common ancestor the arrangement of the bones would have been different.

the graph of the linear equetion 3x + 5y - 15 = 0 cuts the y - axis at the point full solution
Answer:
y = [tex]-\frac{3}{5}x+3[/tex]
Explanation:
3x + 5y - 15 = 0
So we want to get it in the form y = mx + b
Subtract 5y from both sides;
3x - 15 = -5y OR -5y = 3x - 15
Divide both sides by -5
y = [tex]-\frac{3}{5}x+3[/tex]
