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.
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.

In a transformation experiment, a sample of E. coli bacteria was mixed with a plasmid containing the gene for resistance to the antibiotic ampicillin (ampr). Plasmid was not added to a second sample. Samples were plated on nutrient agar plates, some of which were supplemented with the antibiotic ampicillin. The results of E. coli growth are summarized below. The shaded area represents extensive growth of bacteria; dots represent individual colonies of bacteria.
1. Wildtype + No Amp: Lawn
2. Wildtype + Amp: No growth
3. Plasmid + No Amp: Lawn
Which of the following best explains why there is no growth on plate II?
A. The initial E. coli culture was not ampicillin-resistant.
B. The transformation procedure killed the bacteria.
C. Nutrient agar inhibits E. coli growth.
D. The bacteria on the plate were transformed.

Cells may have receptor proteins in the cytoplasm that respond to touch.
Cells may have receptor proteins of specific shapes that certain molecules fit in
Cells may have receptor proteins that repel certain sig
Answer:
Cells have different receptors that are specific for different molecules. Receptors can also respond directly to light or pressure, which makes cells sensitive to events in the atmosphere.

what is pressure and how do we get it
Answer:
pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.
Calculating pressure
To calculate pressure, you need to know two things:
Pressure is calculated using this equation:
pressure = force ÷ area.

Answer:
yes, these are isotopes of nitrogen.
Explanation:
Any atom with the same number of protons, but a different number of neutrons is called an isotope. Nitrogen has 7 protons and 7 neutrons. If it had a different number of protons, it would be a different element. Since we know both elements A and B are Nitrogen and therefore both have 7 protons, that means they have 8 and 9 neutrons, respectively. Therefore, they are isotopes of Nitrogen.

Which of the following can you infer from the information in the table below? Hominid species Evidence H. Neandertalensis Physical features include skeleton suited for upright walking, hands, and large brains. Burial sites contain artifacts like flowers, food, and weapons. All fossils found have been radiocarbon dated to be 130,000 to 35,000 years old. H. Sapiens Walk upright, have thumbs used for making tools. Large brains Bury their dead ceremonially. Fossils found in sediment layers containing volcanic ash crystals that are 195,000 years old H. Neandertalensis and H. Sapien were able to mate and produce offspring. H. Neandertalensis is not a direct ancestor of H. Sapien. H. Sapien is a hominid branch that will become an evolutionary dead end. H. Sapien and H. Neandertalensis did not occupy the same geographic region.
We can infer from the information in the table below information about the evolution.
Evolutionary History of Modern Man1) Modern shares a common ancestor with gorillas and chimpanzees.
2) Some species before sapiens sapiens, according to the evolutionary process, are:
AustralopithecinesErgasterRectusNeanderthalensis and sapiens.3) Australopithecines inhabited the arboreal savannas of Africa around 2.8 to 2.3 million years ago.
4)Several species of australopithecines were able to walk upright or semi and had small brains.
5) During this period, Africa was undergoing a series of environmental changes that transformed its arboreal savannas, inhabited by australopithecines, into open savannas.
6) Thus, the australopithecines began to be exposed to predators, due to the decrease in shelters. This fact led to the extinction of most australopithecines.
Only a few lineages were able to adapt and survive, allowing the emergence of hominids.
With this information, we can know a little more about the evolution process of the human species.

Suppose a species lives in an ecosystem with unlimited resources and no predators. What is the shape of its population versus time graph? help ASAP
Answer:
D. a curve that increases exponentially as time passes
Explanation:
I just took the test
A population growth curve that increases exponentially as time passes would result if a species has unlimited resources and no predators.
Exponential population growthExponential population growth occurs when a population is capable of reaching its biotic potential.
With unlimited resources and a lack of predators, the population of a species continues to grow exponentially without any hindrance. This result is a J curve.
With limited resources, the population might increase exponentially initially and will level off as the carrying capacity of the ecosystem is reached.

Answer:false
Explanation:
brackish water occurs when fresh water goes into the ocean and mixes.
Brackish water is common in freshwater wetlands. The statement is false
What is brackish water ?
Brackish water with salinity levels between seawater and freshwater, when surface or groundwater mixes with seawater brackish water formed in deep fossil aquifers.
Brackish water is undervalued can be used for irrigation and most industries can’t use it and not fit for consumption by humans or livestock. Brackish water is easier to desalinate than seawater.
The global warming and climate change show an impact on the composition and increased occurrence of brackish water. Due to global salt levels increases, the level of brackish water, increases.

Name two major types of mutations. What do they have in common? How are theydifferent? Give an example of each.
Answer:
Two major categories of mutations are germline mutations and somatic mutations.Germline mutations occur in gametes. These mutations are especially significant because they can be transmitted to offspring and every cell in the offspring will have the mutation.
Somatic mutations occur in other cells of the body.
