The biggest difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus.
Presence of nucleus and nuclear membrane in eukaryotes distinguishes them from prokaryotes.
What is the difference between prokaryotes and eukaryotes?Prokaryotes have primitive body structure and they lack nucleus while a well defined nucleus and nuclear membrane is present in all eukaryotes.
Prokaryotes do not have membrane bound cell organelles whereas eukaryotes contain membrane bound organelles like endoplasmic reticulum, mitochondria etc in their cellular structure.
Prokaryotes are made up of single cell while eukaryotes are mostly multicellular organisms.
Prokaryotes are smaller organisms with the size ranging from 0.1 to 5um. The eukaryotes are larger in size. Their size ranges from 5-100um.
Mode of cell division is binary fission in prokaryotes while in eukaryotes it is through mitosis.
Prokaryotes contain one chromosome whereas many chromosomes are seen in eukaryotes.
Bacteria and archaea constitute prokaryotes while plants and animals comprise eukaryotes.
Therefore, prokaryotes are simpler than the eukaryotes.

if there is a low concentration of sucrose to water (so there’s more water than sugar in a solution) outside of a cell, will the cell shrink or expand? and why (using osmosis to explain)?
i believe that the cell will expand because there is less sugar in the water. if you were to add more sugar into the water, then the cell will shrink in size because sugar and salt is the same thing if you add it in water.
What is the role of acetyl-CoA? Where does it fit into the Krebs cycle?
acetyl CoA: Acetyl coenzyme A or acetyl-CoA is an important molecule in metabolism, used in many biochemical reactions. Its main function is to convey the carbon atoms within the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.
Acetyl-CoA plays a key role in the Krebs cycle where it delivers the acetyl group for further metabolism. It is produced from the three-carbon pyruvate molecule and enters the Krebs cycle by combining with oxaloacetate to form citrate.
Explanation:Acetyl-CoA is a crucial molecule involved in many biochemical pathways in cellular organisms where it plays a key role in delivering the acetyl group to the citric acid cycle (Krebs cycle) for further catabolism.
The three-carbon pyruvate molecule generated during glycolysis is converted into a two-carbon acetyl coenzyme A (acetyl CoA) molecule by the enzyme pyruvate dehydrogenase. This transformation releases carbon dioxide and transfers two electrons that combine with NAD* to form NADH.
Acetyl CoA then enters the Krebs cycle by binding to a four-carbon molecule oxaloacetate to form a six-carbon molecule citrate or citric acid. In the process the coenzyme A molecule is simultaneously released.

Imagine that you are buying books one by one and then piling them up after reading them. Which geologic concept could you use to identify the topmost book as the newest?
A.
principle of inclusion
B.
principle of lateral continuity
C.
law of superposition
D.
principle of unconformities
Answer: Law of superposition.
Explanation: The law of superposition is an axiom that can be used as the basis of geology and archaeology.
This is a form of relative dating which can be used to determine the age of the rock. It states that the oldest layer will be at the bottom of the sequence and the newest layer formed will be at the top of the sequence.
Buying books and piling the books after reading them shows the law of superposition.

40 POINTS! DON'T GUESS! Millions of years ago, the Indian plate began pushing gradually towards the Eurasian plate. The land above started rising in various patterns. Which physical feature most likely resulted from such a motion?
This is probably a mountain. It was caused by the crust moving together. When one tectonic plate moves beneath another at a plate boundary the plate boundary it is called is Convergent boundaries. So mountains form at convergent boundaries.
Folded mountain with waves, twists, and turns
Its actually beautiful there!
The Himalayas is the physical feature resulting from the collision between the Indian and Eurasian tectonic plates. This ongoing process causes the rise of the mountains and frequent seismic activity in the region.
Explanation:The physical feature that most likely resulted from the motion of the Indian plate pushing towards the Eurasian plate millions of years ago is the Himalayas. This massive mountain range was formed by the collision of the two tectonic plates, a process that continues to this day. As the plates collide, the land above is pushed upward, forming the mountain ranges we see. The continued pressure not only results in the elevation increase of the Himalayas by one to five millimeters per year but also makes the region seismically active, leading to frequent earthquakes and tremors.
The creation of the Himalayas and other mountain ranges such as the Tibetan Plateau is a prime example of the dynamic nature of Earth's crust caused by plate tectonics. This geologic activity reflects the constant motion of tectonic plates and the associated heat transfer process that helps cool the Earth's interior.

What happens to the portion of the cell membrane that surrounds a large molecule during endocytosis?
it separates from the membrane.
hope this helps.
Answer:
Endocytosis is a cellular process in which large molecules, parts of cell and whole cell enter the cell from the external environment without passing through the plasma membrane directly.
Although material do not pass directly through plasma membrane but membrane is constantly being remodeled by this process as plasma membrane invaginates, form a pocket around macromolecule and pinches off from the plasma membrane and forms an intra-cellular vesicle and transport the macromolecule within.
Thus, after surrounding target material plasma membrane pinches off and form vesicle.
