Answer:
C. The salt is dissolved by the water
Explanation:
When ionic compounds dissolve in water, the individual ions separate and get surrounded by water molecules—a process called solvation. Because the salt ions are charged, they dissolve much better in a polar solvent, which is also slightly more charged than a nonpolar solvent

Which of the following best describes a tissue?
Group of answer choices
A group of organs that all have similar functions.
A group of similar cells that serve the same purpose
A random collection of cells.
A singe cell that has a specific function.
Answer:
I would say b
Explanation:
it would be b because tissues that are similar form one organ but a group of organs is a system so its b.
The best statement that describes a tissue is - A group of similar cells that serve the same purpose.
In multicellular organisms, tissue is a cellular organizational level that is present between similar cells and a complete organ. It is a group of cells that have a similar structure and function.
The space between cells in tissue is filled with a nonliving material, the intercellular matrix that varies from tissue to tissue in amount.Various tissues then undergo organization to form organs. Cells are the most basic part of an organizationtissues make muscles that help in movementThus, "A group of similar cells that serve the same purpose" is best describes tissue.

What difference do you see between ribose and deoxyribose sugars?
What is RNA ?
What is replication?
Answer:
ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
Explanatioim smart now give brainliest plz
Answer:
Ribose, found in RNA, is a "normal" sugar, with one oxygen atom attached to each carbon atom. Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy"). In ribose, carbon atom #2 carries one hydroxyl group (colored red).
RNA is a ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.Explanation:
Which chemical is released by (2) WBC's that produces a non-specific inflammatory response?
Answer:
cytokines
Explanation:
Non-specific immune responses are integral to host cellular defense mechanisms. It is a general response, mediated by white blood cells, where cells rapidly react to pathogenic infiltration.
Here receptors on cells recognise molecules shared by a broad spectrum of pathogens, or even react to signals from damaged, injured or stressed cells like inflammatory cytokines in a cytokine storm.
Why does salt affect water potential? (Osmosis related)
Answer:
Explanation: Las sales reducen el potencial osmótico del agua, aumentando la necesidad de energía que requieren las plantas para extraer la humedad del suelo, volviéndolas más susceptibles al marchitamiento.
Name the site of production and release of oestrogen
Answer:
The pituitary gland produces FSH which causes the development of a follicle in the ovary. As the egg develops inside the follicle, the follicle produces the hormone oestrogen. The oestrogen causes growth and repair of the lining of the uterus wall. Oestrogen inhibits FSH.

Which procedure will determine if water temperature affects the weathering of sedimentary rocks?
A. Test 3 identical sedimentary rocks, 1 each in 3 different water temperatures.
B. Test 3 identical sedimentary rocks in 1 water temperature.
C. Test 1 crushed sedimentary rock and 1 whole sedimentary rock in water.
D. Test 3 identical sedimentary rocks, 1 each in acid, 1 in a base, and 1 in water.
Answer:
The correct option is A
Explanation:
To determine if water temperature has an effect on weathering of sedimentary rocks, different number (perhaps three) of identical sedimentary rocks should be obtained and then individually placed in different water temperatures (with at least one of the "water volumes" used for each having a temperature close to the room temperature so as to be used as the control).
Thus, each of the identical sedimentary rock can be broken into three and placed individually; as in one part of the rock in 20 °C of water (control), another part of the rock in 40 °C and another in 60 °C of water.
This above procedure should be repeated for the remaining two other identical sedimentary rock to confirm if there is any effect.

What type of organic compound is used to store and release large amounts of energy?
Answer:
A carbohydrate is an organic compound such as sugar or starch, and is used to store energy. Like most organic compounds, carbohydrates are built of small, repeating units that form bonds with each other to make a larger molecule. In the case of carbohydrates, the small repeating units are called monosaccharides.
Answer:
Adenosine triphosphate (ATP) is also an organic compound that storages (provides) energy to drive many processes in living cells.
Write about an experience, either real or imaginary using these words chemical energy, electric energy, kinetic energy, mechanical energy, nuclear energy, potential energy, radiant energy, seismic energy, sound energy, and thermal energy
Answer:
I stopped to think for a moment, and realized chemical energy is found in food. Then, I thought about how the other day when I saw lightning, that is an example of electric energy. Then I thought about how when throw a ball, that is a form of kinetic energy. The other day, when I was hammering a nail into a piece of wood, that was a form of mechanical energy. An example of nuclear energy would be the nuclear power plant by our house. Before my book fell off my table, this is an example of potential energy. The energy from the sun is an example of radiant energy. Volcanoes and earthquakes around the world are an example of seismic energy. Sound energy would be the balloon that I popped the other day. Thermal energy would be the heat I feel from the heater.

Relation between chromosome and chromatids:A chromosome is made up two Identical Sister Chromatids. And each sister chromatids are joined at the centromere
A chromatid is one of two identical halves of a replicated chromosome. Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.Each chromosome consists of 2 sister chromatids.Before replication, one chromosome is composed of one DNA molecule. In replication, the DNA molecule is copied, and the two molecules are known as chromatids.Learn more:

What is the genetic code of the reading strand in the DNA model
Most enzymes are proteins. Many cells make and use an enzyme called catalase to facilitate the decomposition of hydrogen peroxide (H2O2). The products of the decomposition are hydrogen (H2) and oxygen (O2). Stephanie is investigating the structure and function of catalase, and she is comparing catalase to other proteins. What can Stephanie predict will distinguish the structure of catalase from the structures of the other proteins she is studying? A. many regions made entirely of hydrogen and oxygen B. the chemical properties of the peptide bonds C. the types of amino acids it contains D. the sequence of amino acids it contains
Answer:
The correct answer is - B. the chemical properties of the peptide bonds.
Explanation:
The difference between the structures of catalase from other proteins depends on the chemical properties of the peptide bonds present in between the amino acids which decide the pH and temperature by their disruption. These bonds present between two alpha-amino acids when carboxyl of one amino acid interacts with the amino group of the other to form an amide-type covalent bond.
