Do rivers have high or low biodiversity
Answer:
high biodiversity
Explanation:
Examples of places with high biodiversity include rainforests and coral reefs, because they have many different species in an area. Less biodiversity areas include deserts, icy areas, and the bottom of the ocean. Organisms do exist in those places, but not as many as places with higher biodiversity.

Answer:
TRUE
First it flows from the sun to autotrophs, or producers. Then it flows from producers to consumers. Energy never flows backward from consumers to producers. When you draw a food chain, always begin with energy from the sun to a producer.

What evidence do you have that water is a covalent compound?
Bonds in a molecule of Water are covalent bonds because the hydrogen and oxygen molecules share electrons, that’s why water is a covalent compound.
What might happen if cytokinesis did not occur during the cell cycle?
Answer:
If cytokinesis did not occur during mitosis the cytoplasm wouldn't be divided and there wouldn't be two identical daughter cells as a result. so the cell would remain to be at rest not being able to separate into two individual cells.

elements as well. Which statements apply ONLY to nuclear fusion?
A)
Fusion begins with an unstable nucleus.
B)
Fusion produces much more energy than fission.
Fusion is the source of nucleosynthesis in stars.
D)
Fusion
utilized in nuclear reactors as a usable energy.
E)

Answer:
B,C, and E
Explanation:
Just did it on usatestprep
According to the question, Fusion produces much more energy than fission. Fusion is the source of nucleosynthesis in stars.
Fusion is the process that supplies the energy we receive from the Sun.
What are the 2 processes that produce nuclear energy?There are two fundamental nuclear processes considered for energy production: fission and fusion.
Fission is the energetic splitting of large atoms such as Uranium or Plutonium into two smaller atoms, called fission products. To split an atom, you have to hit it with a neutron.
Thus, option "B" is correct.

Ethan filled 10 cups of the same size with equal amounts of water. He divided the cups into five groups of two cups each. The groups were placed in five different locations around his house. After two weeks, he measured the remaining water to determine how much had evaporated, by measuring how much water remained in each cup.
Answer:
See the answer below
Explanation:
Ethan filled 10 cups of the same size with equal amounts of water. He divided the cups into five groups of two cups each. The groups were placed in five different locations around his house. After two weeks, he measured the remaining water to determine how much had evaporated, by measuring how much water remained in each cup.
What is the dependent (data) variable?
A. Location of cups
B. Amount of time they were left in locations
C. Amount of evaporated water
D. Size of cups
The dependent variable is the variable whose value is dependent on other variables, particularly the independent variable, in the course of experiments. As the independent variable becomes varied during the experiment, the value of the dependent variable also varies along.
Hence, in this particular scenario, the dependent variable would be the amount of evaporated water. This amount would be dependent on the location of the cups around the house which, in this case, would be the independent variable.
The correct option is C.
When water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into the solution. Which property of water accounts for this occurrence
A) cohesion
B) pH
C) polarity
D) surface tension
Answer:
C) polarity
Explanation:
The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.
In water molecules hydrogen bonds provides a special dipole - dipole attraction. Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine). This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge. This makes the molecule of water polar. By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.This property of water is polarity of water.
The property of water that is at work as described in the question is polarity.
Water is composed of oppositely charged ends; a positive end and a negative end. These oppositely charged ends are called "dipoles".
The occurrence of dipoles in water makes water a polar molecule. Thus, when water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into the solution. This is possible because of the property of polarity possessed by water molecules.

Answering: I believe d
Explanation:
The nucleic acid encodes the genetic information unique for each virus, each virus has its own unique info.
The correct statement is that the nucleic acid contains the genetic information the virus needs to avoid detection.
What is the nucleic acid?They are macromolecules or biological polymers present in the cells of living beings that are carriers of cellular information.
Viruses have a protein capsid and some have an envelope, these consist of a single nucleic acid (RNA or DNA) that encodes the viral genome.
Therefore, we can conclude that the correct statement is that the nucleic acid contains the genetic information the virus needs to avoid detection.

Which statement describes transform boundaries?
Rift valleys are formed.
Mountains are created.
Faults form in the lithosphere.
Plates move toward each other.
The statement that describes transform boundaries is "Faults form in the lithosphere," which is the third option, as transform boundaries occur where two tectonic plates slide past each other in opposite directions.
What are transform boundaries?
Transform boundaries are a type of plate boundary where two tectonic plates move past each other horizontally without being destroyed or created. They occur when two plates slide past each other. This sliding motion results in the formation of cracks or fractures in the lithosphere, which can cause earthquakes. The movement along transform boundaries is typically smooth but can be interrupted by sudden motions that release large amounts of energy and cause earthquakes.
Hence, the statement that describes transform boundaries is "Faults form in the lithosphere," which is the third option.
