Answer:
No
Explanation:
This is because oxygen will not be available for breathing and energy will not be released for cellular activities because photosynthesizing organisms have chlorophyll and trap light energy ffrom sunlight , using carbondioxide and water to produce glucose and oxygen. Oxygen is the by product which is the gas that is inhaled by living organisms during respiration and also break glucose to release ATP. Therefore without these organisms, respiration will be difficult.

Q) In three to five sentences, construct an argument for the claim that natural selection leads to evolution. Provide evidence for this claim, and be sure to explain how an organism shows the four parts of the process of natural selection. You may use any organism with the exception of bacteria and antibiotic resistance.
Answer:
Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.
This method of natural selectionthat the fantastic alleles of this variation organism are surpassed directly to offspring, the system of natural selection results in evolution occurring.
What is natural selection?Natural selection is the system thru which populations of residing organisms adapt and extrade. Individuals in a populace are evidently variable, which means that they're all one of a kind in a few ways.
Natural selection is a mechanism of evolution as there are. Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation. Natural selection is a system in which organisms can be higher tailored to their surroundings will live to tell the tale and reproduce.

Name and describe how at least 1 biotic factor can contribute to changes in gene frequency over
time through natural selection.
Answer:
Change in food source.
Explanation:
If there is a change in food source, then the organism will have to adapt to that change. For example, with Darwin's Theory on the finches on the Galapagos Islands. There were many different varieties from different size to different beaks. This was because of changes on food sources and they adapted to obtain them more.
Natural selection can contribute to variations in gene frequency throughout time as a result of changes in food supply.
Changes in gene frequency:If the organism's food supply changes, it will have to adjust to the new situation.
For example, Darwin's Theory on the Galapagos Islands' finches. There were several distinct types, ranging in size and beak shape. This happened due to changes in food supplies, and they evolved in order to access more of them.

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.
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

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.

No answer text provided.
variation in a population exists
Answer:
variation in a population exists
Explanation:
Variation is present in a population of antelopes so due to this variation, the predator such as lion can catch the slowest antelope that is present in the population while on the other hand, the faster antelopes can save their lives by running very fast. Variation is present in a population of antelopes due to availability of food as well as genetic characteristics. These variation leads to the availability of food to the lions.

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).
