Answer:
The correct answer is - Gel electrophoresis.
Explanation:
Gel electrophoresis is a lab technique used to separate distinct samples of mixed DNA, RNA, or proteins on the basis of their size. In gel electrophoresis, the molecules to be move from one another by an electrical field through a gel with small pores in it. DNA molecules are negatively charged so they move towards positive charge wells in the electric field and get separated.
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.

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.

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.

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).
