When a substances like sugar, salt or lemon juice dissolve into a liquid and appears to "disappear", it is no longer present in the solution.
True
False
Answer:
False.
Explanation:
A solvent is the substance that does the dissolving – it dissolves the solute. In salt solution, water is the solvent. During dissolving, particles of solvent collide with particles of solute. They surround the particles of solute, gradually moving them away until the particles are evenly spread through the solvent.
The molecules are still there.

Answer:
b.
Explanation:
They showed that organic molecules could be formed from materials nypothesized to be available in the Earth's early atmosphere.
What is Stanley miller and Harold Urey?The Miller-Urey experiment tested the hypothesis that life, or more precisely organic molecules, might have arisen by nothing more than straightforward chemical processes by simulating the conditions on the early Earth.
Miller's result confirmed A.I. Oparin's theoretical hypotheses, and it is regarded as the standard experiment looking into the hypothesis of abiogenesis.
The Miller-Urey experiment was the first attempt to investigate theories regarding the beginning of life experimentally. Stanley Miller recreated circumstances that were supposedly typical on the early Earth.
Therefore, They showed that organic molecules could be formed from materials nypothesized to be available in the Earth's early atmosphere.

Two equal strips A and B were from a potato whose cell was 30% of sugar. The strip
A was placed in a solution of 10% sugar concentration while B was placed in 50%
sugar concentration
a) What change was expected in strip A and B
b) Account for the change in strip A
Answer:
Movement occurs from higher concentration to lower concentration.
Explanation:
Strip A cell has 30% of sugar which is placed in a solution of 10% sugar so the sugar that is present in the potato strip A moves from inside to the outside due to the process of osmosis while on the other hand, if strip B was placed in 50% of sugar solution so the sugar moves inside from outside environment through semi-permeable membrane. This movement occurs due to difference in concentration of both environments i.e. cell and solution.
Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50% sugar concentration
a) strip become flaccid and strip B will swell
b) hypotonic solution causes movement of water to diffuse out of cell
Simple diffusionSalts and sugars in solution will diffuse away from areas of high concentration into the surrounding solution
Water also diffuses away from areas of high free water concentration into areas of more solute concentration.here in strip A is placed in low sugar solution that causes movement or diffusion of water from the cell to the solution as it is only 10% sugar concentrationin strip B which is placed in low sugar solution that is placed in high sugar concentration solution that is 50% which means there will be movement of water from solution into the cells of the strip which cause them to swellThus, Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50% sugar concentration

How would this food web be affected by the extinction of the Osprey?
Answer:
The fish would grow in the population, because osprey mainly eat fish.
Because of the fish growth, the ocean, pond, or whatever, makes the water have less oxygen. The fish eat small fish, crustaceans, worms and almost anything that is not poisonous to them. These populations will decrease.
Because there are no Ospreys, the raccoons will get hungry too, as they sometimes eat Osprey eggs.

What might happen to an enzymes activity if the gene encoding its production was altered by a mutation?
Answer:
The enzyme's activity will be altered
Explanation:
Genes are unit of hereditary that carries genetic information needed for the survival of the cell and organism at large. Genes are expressed via transcription and translation processes to produce a protein, which is responsible for the physical traits we can see (phenotype).
Since ENZYMES that catalyze biochemical reactions in living cells are proteinous in nature i.e. are made up of proteins, this means that they are formed from the expression of genes. Hence, if the gene encoding the production of an enzyme is altered or changed due to mutation, then the activity of the resulting enzyme will also be altered (most times non-functional).
Which type of relationship is formed when an Alcon blue caterpillar lives in a Myrmica ant
nest?
commensal
mutualistic
parasitic
Answer:
mutualistic is the correct answer.A mutualistic relationship is formed when an Alcon blue caterpillar lives in a Myrmica ant nest. Thus, the correct option is B.
What is Mutualistic relationship?A mutualistic relationship is an interaction when two organisms of different species work together in such a way that each species is benefiting from the relationship.
The Caterpillars of the alcon blue butterfly have developed an outer coat on their body that tricks the Myrmica ants into believing that the young are its own, this results into duping the ants to carry the larvae back to their colonies to care for. Once in the nest, the caterpillar becomes a parasite. The Myrmica ants will feed the adopted larvae in preference to their own, and the ant colony will produce fewer offspring in the nest.
Therefore, the correct option is B.
