When adding more sucrose to a 0.7 M sucrose solution, why does it not dissolve as readily as it did at a lower molarity? a) the ions in the solution interact with the sugar and that interferes with its solubility b) the solubility of the solute depends on wether the solute has hydroxyl functional groups or not c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules d) hydrogen bonds in the water molecules change the electrical charge of the sugar molecule, which prevents it from dissolving further in the water
Answer:
The correct answer is option c.he solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
Explanation:
The Solution contains a solute (sucrose for this situation) and dissolvable (water for this situation). A saturation or unsaturation of a solution relying upon whether it can even now dissolve a solute or not.
As indicated by this inquiry, the sucrose solution is saturated as the 0.7 M sucrose arrangement doesn't disintegrate the sucrose (solute) anymore. The immersion of the sucrose arrangement happens in light of the fact that the measure of solutes is likening the number of solvents in the solution. The solubility of a particular solution relies on saturation.

Which statement below would be most likely to effect the carbon cycle if a tornado lands and destroys most of the trees in a forest?
A. There would be less fossil fuels in the ground that would be used for drilling
B. Plants would remove less carbon dioxide from the atmosphere
C. An increase in organisms respiration would raise the level of carbon dioxide in the air
D. More resources would be available for animals in the area
Answer:
B
Explanation:
The effect of the carbon cycle if a tornado lands and destroys most of the trees in a forest is Plants would remove less carbon dioxide from the atmosphere.
What impact does the carbon cycle have on land?The important changes in the land carbon cycle are likely to come because of climate change. Carbon dioxide rises temperatures, extending the growing season and increasing humidity. Both factors have led to some additional plant growth. However, warmer temperatures also stress plants.Thus, option "B" is correct.

what makes jupiter similar to the sun
Answer:
Their composition is similar.
Explanation:
They are mostly made of hydrogen and helium.
The structure of jupiter and sun mostly made up of hydrogen and helium.
What are the characteristics of hydrogen and helium?Hydrogen and helium are the lightest elements in the periodic table. They exist as gases at room temperature and are the two most common elements in the universe, with hydrogen making up about 75% of all matter.
It will form a mixture of two of the lightest gases known. Though Hydrogen atoms (H) turn into hydrogen molecules (H2) to form a very reactive, flammable, and explosive hydrogen gas, Helium (He) atoms form an inert gas.
The key difference between hydrogen and helium is that hydrogen is a diatomic gas, while helium is a monatomic gas. Helium has a fully filled s orbital (1s2), but in hydrogen, there is only one electron, so it is unstable.

If 30% of the nucleotides in a single-stranded RNA molecule are adenine, then what percent are expected to be thymine?
Answer:
Explanation:
the base pair of adenine is thymine they are equal in amount in RNA so if 30% of the nucleotide in RNA is adenine so the percentage of thymine would also be equal to adenine that is 30%
If the DNA strand has 30% Adenine in its composition, it means that the same DNA strand has 30% thymine in its composition.
This is because:
DNA is composed of the nitrogenous bases Adenine, Thymine, Cytosine and Guanine.These nitrogenous bases were paired with each other.Adenine pairs with Thymina. While Cytosine pairs with Guanine.Therefore, the amount of Adenine and Thymine in a DNA must be equal. While the amount of Guanine and Cytosine must be equal.In this case, we can conclude that if the DNA has 30% of Adenine, it is mandatory that this same DNA has 30% of Thymine.

Identify the living and non-living parts of the nitrogen cycle.
The nitrogen cycle is a cyclical process in which nitrogen moves through both living and non-living things, including the atmosphere, soil, water, plants, animals, and bacteria.
What is nitrogen cycle?The Nitrogen Cycle is a biogeochemical process in which nitrogen is converted into various forms before passing from the atmosphere to the soil to the organism and back into the atmosphere.
Nitrogen fixation, nitrification, denitrification, decay, and putrefaction are some of the processes involved.
Nitrogen fixation, nitrification, and denitrification are the three major steps in the nitrogen cycle.
It is a biosphere cycle that includes the atmosphere, hydrosphere, and lithosphere. Nitrogen can be found in a variety of reservoirs.
The nitrogen cycle is a cyclical methodology in which nitrogen moves through both living and nonliving systems such as the atmosphere, soil, water, plants, animals, as well as bacteria.

The organism lower on the food chainThe organism higher on the food chainThe organism with a hard body rather than a soft bodyThe organism that lived in a marine or aquatic environmentAnswer:
The organism higher on the food chain
Explanation:
The organism lower on the food chain. Their high reproduction rate, as well as their numerous populations, favor them at the moment of fossilizing under different environmental conditions. The organism higher on the food chain. These organisms tend to be predators or bigger animals, characterized by small populations with a reduced number of individuals in comparison with smaller organisms. The fact that their reproductive rate is not very high, that they live longer and hence they are fewer in number, do not favor their fossilizing possibilities under different environmental conditions.The organism with a hard body rather than a soft body. Hard tissues always increase the possibilities of fossilizing, as their biological or mechanical destruction is not as easy as the destruction of the soft tissues. The organism that lived in a marine or aquatic environment. It seems that those organisms that live in a sedimentary environment, such as the sea or a lake, or those that live buried or fixed to the bottom, have more possibilities of fossilizing.Do protists (amoeba, Euglena, Paramecium) use similar structures to move? Explain.
Answer:
Most protists move with the help of flagella, pseudopods, or cilia. Some protists, like the one-celled amoeba and paramecium, feed on other organisms. Others, such as the one-celled euglena or the many-celled algae, make their food by photosynthesis. ... Theyuse pseudopods to move away from bright light or to trap food.
Within the protist kingdom, organisms have developed very similar structures that are used to move around the environment.
The protist kingdom is primarily comprised of very small, single-celled organisms. Among the vast number of organisms that make up this kingdom are algae and amoebas. Over the course of history, these organisms have evolved very similar means of mobility.
Within the protist kingdom, most of the organisms move with one of the structures:
CiliaPseudopodiaFlagellaThese three structures used by protist to move are very similar in that are all structural extensions on the exterior limit of a cell. Though clear differences exist in the number or other uses of these extensions, it is clear that all of the members of this kingdom have evolved similar means of mobility.
