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:
Phenotype ration of Green : other color plant will be 3:1
Genotype ration would be GG:Gg:gg
1:2:1
Explanation:
Let the dominant allele for green color of plant be G
Recessive allele for the above allele pair would be g let us say that "g" imparts black color
Then the genotype of two heterozygous green plants would be "Gg"
Gg * Gg
GG, Gg, Gg, gg
The three individuals of genotype GG, Gg, Gg will have green color
while the gg individual will have black color (as assumed)
Phenotype ration of Green : other color plant will be 3:1
Genotype ration would be GG:Gg:gg
1:2:1
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
a) strip become flaccid and strip B will swell
b) hypotonic solution causes movement of water to diffuse out of cell

D. grasshopper
Answer:
The answer is D. grasshopper. A primary consumer is one that eats plants.
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).

4. Do you think that greenhouse gases are essential for maintaining an average global temperature?
Explain why or why not you think so using evidence from the simulation
Answer:
I don't think so
Explanation:
An excessive amount of greenhouse gases cause the earth's temperature to rise and contribute to climate change. I didn’t do the simulation but too many greenhouse gases are bad for the environment. They raise the temperature of the earth instead of maintaining it.

Justify a physician has a patient, age 42 whose blood pressure averages 141/89 mm hg. Why might the physician recommend healthful life choices to the patient.
Answer:
Due to high blood pressure.
Explanation:
The physician recommend healthful life choices to the patient because the patient has high blood pressure. The normal range of blood pressure is 120/80 mm hg whereas the high blood pressure is considered to be 140/90mm Hg so we can say that the patient has high blood pressure which can be normalize by attaining healthful life style such as eating healthy food, regular exercise and avoiding stress.

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.

Over 1 million species of animals have been named and described by biologists. These species arose __________. View Available Hint(s) Over 1 million species of animals have been named and described by biologists. These species arose __________. before the Cambrian explosion through years of evolution as natural selection shaped animal adaptations to Earth's environments from island-bound populations of individuals as a result of evolution from a common fungal ancestor
Answer:
through years of evolution as natural selection shaped animal adaptations to Earth's environments.
Explanation:
Over the years, biologists have been able to successfully name more than one (1) million animal species across the world. These species arose through years of evolution as natural selection shaped animal adaptations to Earth's environments.
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
Why is there so much biodiversity on Earth? Provide at least two examples
Answer:
climate and agriculture
Explanation:
for example the coconuts of the pacific warm water islands are far different than the crab apples of the north or how the heat of the south means for less clothes while the brisk of the north requires more layers.
Explanation:
There are several key reasons for high biodervisity in tropical ecosystems. High NPP directly contributes to a diversity by supporting more species with minimum viable populations of each organism increase overall mutation frequency and hence intraspecific genetic varation.
