a student carried out an experiment to determine how different concentrations of sucrose solution will affect osmosis. the student set up dialysis tubing bags of different sucrose concentrations. then the student massed the bags, placed them in beakers of distilled water for thirty minutes, and then removed the bags. the masses were taken again and the percent change for each bag was calculated. the results were graphed and are shown here. which statements best summarize the experimental data. choose all that apply.
a. low sucrose concentrations caused more water to move out of the bags
b. high sucrose concentrations cause more water to move out of the bags
c. low sucrose concentrations caused more distilled water to move into the bags.
d. high sucrose concentrations caused more distilled water to move into the bags.
e. there is a correlation between sunrise concentration in the bag and the rate of osmosis in the bag.
Answers
The inference is that high sucrose concentrations caused more distilled water to move into the experimental bags.
What is osmosis?It is the movement of water molecules from the region of high water potential (low solute concentration) to the region of low water potential (high solute concentration) through a selectively permeable membrane.
Thus, the higher the concentration of sucrose in the bag, the lower the water potential, and the more water molecules move into the bag.

discuss why too much respect for the feelings of those involved in conflict may hamper your attempt to effectively resolve it
Answers
We can say that too much respect for the feelings of those involved in a conflict may hamper your attempt to effectively resolve it because it generates bias.
What is bias?Bias is the inclination to side with one individual or group over another. This can be the case in the situation described as one might have too much respect for the feelings of those involved in a conflict and thus feel identified by them, causing a bias that affects your ability to make neutral decisions that can benefit all parties involved.

both carbohydrates and fats provide erorgy, why is it that you get a sugar high,
ut not a fat high?
Answers
Answer: The body uses three main nutrients to function --- carbohydrate, protein, and fat. These nutrients are digested into simpler compounds. Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins.
Cells in the pancreas can release glucagon, a hormone that signals the body to produce glucose from glycogen in the muscles and liver and release it into the blood.When glycogen is used up, muscle protein is broken down into amino acids. The liver uses amino acids to create glucose through biochemical reactions.Fat stores can be used for energy, forming ketones.Other hormones can raise the blood sugar level, including epinephrine (also called adrenaline) and cortisol released by the adrenal glands and growth hormone released by the pituitary gland.sorry if im wrong and have a wonderful day kind person!!!!!!

brainly Carolus Linnaeus developed a classification system very close to the one that we use today. In particular, we still follow the protocol of giving each unique species a name using binomial nomenclature, a two-word naming system. Which statements describe the major importance of our current classification system
Answers
The major importance of our current system of classification is that it helps to correctly identify living organisms.
This is because the classification system gives us information concerning the characteristics of each organism.
What is binomial system of nomenclature?This is the system used in naming living organisms. Every living thing is given two different names:
The generic name
The specific name
The generic name is the name of the genus the organisms belongs to while the specific name is the name of the species to which it belongs.
These two names together ( genus and species names ) are collectively known as the scientific name
For instance:
The scientific name for :
Grasshopper is Valanga nugriconis
Valanga is the genus which grasshopper belongs to and nigriconis is the name of its species
Pineapple is Ananas comosus
Orange is Citrus sinensis

Answers
Answer:.nitrates

Explanation: the variations of the nitrogen bases are: [tex]NO3[/tex] (nitrate), which is found in the plant nodules that we feed on,
.Ammonia, which is excreted by us through urines, which also contains nitrogen, which when absorbed into the soil, form ammonium salts
.proteins, that we get when we feed on nitrogenous foods, which when we die they get decomposed into nitrates and ammonia.
.ammonium salts, teat are changed by the nitrifying bacterias into nitrogen gas which returns back in the atmosphere
.
The four nitrogen bases contribute to the variation between humans because the order of nucleotides determines phenotypic features associated with genetic inheritance.
In DNA, there are four types of nucleotides, each containing one different nitrogen base.The four nitrogen bases in DNA nucleotides are Adenine, Guanine, Cytosine, and Thymine.The linear order of these nucleotides in genes largely determines the phenotypic features associated with genetic inheritance.In conclusion, the four nitrogen bases contribute to the variation between humans because the order of nucleotides determines phenotypic features associated with genetic inheritance.

The molecules in the box on the right are in low concentration gradient. The box on the left has an area of high concentration and an area of low concentration. Scientists would say there is a concentration high concentration gradient.
What is the concentration gradient?
The concentration gradient is the presence of a substance at a specific place. A low concentration gradient means when a substance is dispersed and present far from each other.
A high concentration gradient means when there is a large amount of substance present in a place. These words are used when there is transfer of molecules along the plasma membrane.
Diffusion and osmosis are the two processes by which the transfer of molecules happens.

Free fatty acids and monoglycerides are transported across the microvillus with ________________transport and the glycerol by ___________________ transport during the mucosal phase of digestion.
Answers
Passive transport is used by free fatty acids and monoglycerides and the glycerol is transported by carrier-mediated transport during the mucosal phase of digestion.
What is cellular transport?It is the movement of molecules between the cell interior and the exterior through the cytoplasmic membrane.
Characteristics of cellular transportPassive transport is one where energy is not required for the substance to cross the plasma membrane, it transports part of the monoglycerides and fatty acids.Active transport is one where carrier proteins must move molecules against a concentration gradient, such as glycerol.Therefore, we can conclude that active and passive cellular transport is the transfer of molecules from one side of the cell membrane to the other.

Secretory proteins are:____.
a. produced by ribosomes on the smooth endoplasmic reticulum.
b. chemically modified in the nucleus.
c. produced by the cell for internal use.
d. released from the cell through the plasma membrane.
Answers
The correct answer is Secretory proteins are produced by ribosomes on the smooth endoplasmic reticulum.
What are secretory proteins?Secretory proteins include both endocrine and exocrine proteins that are secreted by cells. Secretory proteins are found in a wide variety of hormones, enzymes, toxins, and antimicrobial peptides. Protein secretory molecules are created by the endoplasmic reticulum.
An average of 3-5 amino acids are produced by ribosomes at the cytosolic face of the ER in mammalian cells every second.
The intestinal epithelium is composed of the enteroendocrine, Paneth, goblet, and absorptive enterocyte cell lineages as well as three other types of secretory cells. The fifth and least typical type of intestinal cell is called a tut cell.
Hence, the correct answer is Secretory proteins are produced by ribosomes on the smooth endoplasmic reticulum.
