Answer:
Water dissociates ionic compounds.
Explanation:
The presence of the molecule 's positive charged end and negatively charged end is referred to as polarity. The extremity of the water is progressively responsible for the active dissolution of other polar objects, such as sugars and ionic mixtures, such as salt. In water, ionic mixes break down to form ions. In view of the fact that the reactants must be disintegrated in water for most natural responses to occur, this is important to note.Since water can break down such large amounts of basic substances, it is known as the dissolvable all-inclusive. Substances (for example, oils) that can not be broken down by water are considered dissolvable fat and are non-polar, non-ionic exacerbates that are strongly reinforced covalently.
Water dissociates ionic compounds. So, the correct option is B.
What is Water?Water is defined as the inorganic compound having the chemical formula H₂O which is a transparent, tasteless, odorless and almost colorless chemical substance, which is the main constituent of the Earth's hydrosphere and the fluids of all known living organisms.
Water molecules have extensive hydrogen bonding which results in unusual properties in condensed form that lead to high melting and boiling points, when compared to other liquids, water has high specific heat, thermal conductivity, surface tension, dipole moment, etc. it dissociates ionic compounds.
Thus, Water dissociates ionic compounds. So, the correct option is B.

What is volume?
Describe the standard units of liquid volume.
What is mass (weight)?
Describe the standard units of mass.
Answer:
Explanation:
1. "Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre. "
2. "In the CCSS, the unit of liquid volume introduced in Grade 3 is liter (L), which is a standard unit in the metric (or SI) system. Another commonly used unit of liquid volume is milliliter (mL), where 1000 mL = 1 L. Many soda bottles are 500 mL, 1L or 2L."
3. "The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it."
4. "The standard International System of Units (SI) unit of mass is the kilogram (kg). The kilogram is 1000 grams (g), first defined in 1795 as one cubic decimeter of water at the melting point of ice."

Choose all that explain why carbon is so important to life.
Carbon (C) appears in the second row of the periodic table and has four bonding electrons in its valence shell.
Carbon can form ionic bonds when combining with metals and covalent bonds with nonmetals.
Carbon can bond to itself in many different ways: chains, rings, branched chains.
Hydrocarbons contain only carbon, hydrogen, and oxygen.
Carbon can form single, double or triple covalent bonds.
Because carbon can bond in so many different ways, a single molecule can have different bonding configurations or isomers.
Answer:
A, C and D
Explanation:
It creates no ionic bonds because it would need certain changes to it.
Im not so sure about E because the configurations are very similar.
And A seems to make sense because its essential to life itself.

Javier decides to test which type of fertilizer works best on his begonias. He sets up flowers in 20 pots and divides them into groups of five. He waters three of the groups with three different brands of fertilizer and the last group with plain water. After 2 weeks, he measures how much each plant has grown.
What is the independent variable in this experiment?
What is the dependent variable in this experiment?
What is the control group in this experiment?
Answer:
The correct answer is :
The independent variable -types of fertilizers
The dependent variable - the growth of plants
The control group - plant gets water only
Explanation:
In any scientific experiment or study, the subject of the research gets a variable treatment that is manipulated or changed to check the different variable which shows the response to change made, variables that manipulated called as the independent variable. Types of different fertilizers are independent variable in this experiment.
The variable that shos response to a change in the independent variable called the dependent variable, the response in this study is the growth of the plants.
The control group in any study is the group that did not receive the treatment other groups receive, that is plants receive water only.

Explanation:
Using the data, choose one of the 3 possible problems below. Justify your choice by writing a hypothesis to explain how it has stopped Claire from breaking down her food. The hypothesis is your first explanation. You will be able to revise it as you do more experiments.
Low Enzyme Production is the reason for no breaking down of food.
If the digestion of food did not occur so it means that there is low enzyme production because enzymes are responsible for the breaking down of food substances into simpler ones in order to absorb by the cells for the generation of energy in the form of ATP. So we can conclude that low enzyme production is the only reason for the stopping of breaking down or digestion of food.

what tiny cell structure carries out a specific function within the cell
Answer:
Tiny cell structures, called organelles, carry out specific functions within the cell. Similar to the way your stomach, lungs, and heart have different functions in your body, each organelle has a different function within the cell.
These small cell structures are called organelles that perform specific functions within the cell. Just as the stomach, lungs, and heart have different functions in the body, each organelle has a different function within the cell.
What are Organelles?An organelle is defined as a subcellular structure that has one or more specific functions for the cell to perform, such as an organ in the body. The more important cell organelles are the nucleus, which stores genetic information; mitochondria, which generate chemical energy; and ribosomes, which assemble proteins.
It's the specific structure within a cell, and there are many different types of organelles also called vesicles within the cell and they actually have a function that's important, because we need to compartmentalize all the functions within the cell.
Thus, these small cell structures are called organelles that perform specific functions within the cell. Just as the stomach, lungs, and heart have different functions in the body, each organelle has a different function within the cell.

Of the nine gigatons of carbon released into the atmosphere by human activity how much is taken up by ocean sediments? how much is taken up by net terrestrial uptake? what is the surplus of carbon in the atom as a result of human activities per year?
The amount of carbon taken up by ocean sediments , terrestrial uptake and the surplus are;
- Ocean sediments; 30%
- Terrestrial uptake; 25%
- Surplus; 45%
The process described above in simple terms is basically the process of capturing and storing atmospheric carbon dioxide. This process is known as carbon sequestration. In carbon sequestration, the amount of carbon stored in reservoirs called oceanic sink is usually more than the amount in the atmosphere.Now, out of the carbon emitted to the atmosphere by human activities, it has been discovered that about 30% is taken up by the oceans, 25% is incorporated into terrestrial ecosystems and 45% remains in the atmosphere.Read more at; https://brainly.com/question/2463576

What are the functions of cell membrane?The identification, communication, regulation of solute exchange through the membrane, and isolation of the cytoplasm from the external environment are the four primary functions of the plasma membrane.
Membranes in biology serve three primary purposes: they prevent harmful substances from entering the cell; they have receptors and channels that make it possible for specific molecules, like ions, nutrients, wastes, metabolic products, and toxins, that mediate cellular and extracellular activities.
The substance's entry and exit from the cell are controlled by the membrane, which is selectively permeable. Protection from the external environment is one of the functions.
