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.
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.

What device is used to measure water forming on the glacial ice sheet?
The device that is used to measure water forming on the glacial ice sheet is known as the Airborne Topographic Mapper (ATM).
What do you mean by Glacial Ice sheets?Glacial ice sheets may be defined as a mass or accumulation of glacial ice of more than 50,000 square kilometers. This sheet significantly contains about 99% of the freshwater on Earth and is sometimes called continental glaciers.
According to the context of this question, an instrument known as the Airborne Topographic Mapper (ATM) considerably collects the elevation of the ice surface along with its thickness. Apart from this, it also measures the formation of ice from water on the glacial ice sheet.
Therefore, the Airborne Topographic Mapper (ATM) is a device that is used to measure water forming on the glacial ice sheet.

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).

In the 1950s, Stanley Miller and Harold Urey conducted experiments in which they fired electrical sparks in the presence of a mixture of different gases. How d these experiments contribute to the theory of the origins of life on earth?
A They determined that the age of organic molecules can be measured by the half-life of isotopes
B They showed that organic molecules could be formed from materials nypothesized to be available in the Earth's early atmosphere
C They proved that organic molecules formed from the accumulation of debris from space
D They discovered that organic molecules would not have formed without the presence of oxygen in the atmosphere
biology spring assessment 2020-2021
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.

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.

Answer and Explanation:
The people within this age range most likely want a baby for themselves/want more babies, or they don't feel like they should have to be limited to the amount of babies they want. Since it is their life and their bodies, they think it is up to them to decide how many to have and whether to have one or not.
