Unlike eukaryotes, bacterial DNA is not enclosed by a nuclear membrane. instead, bacterial DNA is condensed into a region called the nucleoid.
Eukaryotes are the organisms that possess the eukaryotic cell. The eukaryotic cell is advanced type of cell with well-defined nucleus and also the cell organelles are present. Eukaryotes can have both 70S and 80S type of ribosomes.
Nucleoid is the condensed region in the prokaryotic cell that comprises of the genetic material, the DNA. It is an irregular shaped structure lying in the cytoplasm of the cell. There is usually a single pair of chromosome present in the nucleoid.

The difference in concentration between solutions on either side of a cell membrane is?
The difference in concentration between solutions on either side of a cell membrane is a concentration gradient.
In the field of biology, a concentration gradient can be described as a difference in the concentration of molecules inside and outside of a cell. It is due to concentration gradient that molecules move into and out of a cell through the cell membrane.
Some molecules move from an area of higher concentration gradient to an area of lower concentration along the concentration gradient. Diffusion is an example of such a process.
On the other hand, some molecules move from an area of lower concentration to an area of higher concentration against the concentration gradient. Active transport is an example of such a process.

Which phrases apply to metamorphic rocks? Check all that apply.
Oform under extreme heat and pressure
form from existing rocks
Oform from magma and lava
Oform when sediments combine
Oform from volcanic eruptions
Answer:
Oform under extreme heat and pressure form from existing rocks
Oform when sediments combine
Oform from volcanic eruptions
Explanation:
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.Sedimentary rock may be broken down into sediment once again by weathering and erosion. It may also form another type of rock. If it becomes buried deep enough within the crust to be subjected to increased temperature and pressure, it may change into metamorphic rock.
Answer:
from under extreme heat and pressure, form from existing rocks

After soaking for one hour in a solution of unknown concentration, a slice of potato appears to be very soft and limp. you can determine that the solution is:______
If the potato slice becomes soft and limp after soaking for one hour in the solution, the solution is hypertonic.
What is a hypertonic solution?In biology, a hypertonic solution is a solution with more solute concentration than it is found in the sap of any other cell placed in it.
Such solutions have lower water potential than the cells placed in them. Thus, water will readily move by osmosis from the sap of the cells into the solution.
Cells that are placed in hypertonic solutions, therefore, usually end up becoming flaccid as a result of water loss.
So, if after soaking for one hour in a solution whose concentration is not known, a slice of potato becomes soft and limp, it means the solution is hypertonic.

Within absorptive columnar cells re-synthesized triglycerides are incorporated into ______ before exocytosed through the basal side.
Within absorptive columnar cells re-synthesized triglycerides are incorporated into nascent triglyceride-rich lipoprotein particles, termed chylomicrons before exocytosed through the basal side.
Once consumed, triacylglycerol is hydrolyzed into free fatty acids and monoglycerides in the small intestine prior to absorption. Once these compounds enter the intestinal cell, they are used to resynthesize triacylglycerol.
This lipid is then incorporated into nascent triglyceride-rich lipoprotein particles, termed chylomicrons, for subsequent introduction into peripheral circulation.
Chylomicrons are secreted directly into the lymph before entering the blood stream. Once in circulation, triacylglycerol is hydrolyzed before crossing the plasma membrane of peripheral cells.
The primary enzyme that hydrolyzes triacylglycerol in plasma is lipoprotein lipase.
Lipoprotein lipase hydrolyzes triacylglycerol into free fatty acids and 2-monoacylglycerol. The enzyme is attached to the luminal surface of capillary endothelial cells via a highly charged membrane-bound chain of heparin sulfate-proteoglycans.

Nitric oxide (no) participates in a signal transduction pathway that promotes relaxation of smooth muscle cells lining blood vessels and so increases blood flow. nitric oxide accomplishes this by:_______
Nitric oxide accomplishes this by elevating cGMP levels.
NO is the unmistakable message. It dissolves in aqueous solution but is a gas. It is free radicals with free electrons that react with protein thiol groups to form new complexes. Unlike other second his messengers, NO does not require energy to enter or exit the cell. They can go wherever they want, but being reactive free radicals, they cannot travel very far. NO functions as a second messenger within NO-producing cells. It functions as a paracrine molecule that can travel 10-20 times the cell diameter to affect the biology of surrounding cells. It can form complexes with proteins such as hemoglobin, glutathione, and other proteins and be separated from those complexes.Therefore, increasing cGMP levels is necessary.

Answer: The answer is facilitated diffusion, simple diffusion , facilitated diffusion , active transport and simple diffusion.
Explanation: Facilitated diffusion is the process of passive transport in which the ions or the molecules moce or trasported across the biological membrane via transmembrane integral protein or protein channels and they do not need the ATP as energy whereas in simple diffusion the movement of ions and the molecules takes place but without the help of any kind of proteins and it happens through the semi permeable membrane and lastly the active transport is the movement of ions and molecules against the concerntration gradient and requires energy by hydrolysis of ATP and uses it .
In first case the aquaporins are used which are transport channels or helper proteins so it a passive transport but facilitated by proteins so is facilitated diffusion.
In second case it is simple diffusion because due to the smaller size of water molecules the they move and doesn't require any kind of help while doing so.
In third case as the movement is down the gradient and the molecules are charged so is an example of facilitated diffusion.
In the fourth case as the inward movement of glucose is needed and to move from inside the cell to outside the cell it is against the concerntration gradient so it will require the ATP hence is active transport.
In the fifth case as glucose is already in high amount so can easily diffuse inside the cell hence is simple diffussion.
