Answer:
Burning sugar results in a chemical reaction
Explanation:
Flammability, odor, and density are just a few examples of characteristic properties of a substance. A chemical reaction occurs when molecules interact with one another and the molecules change. For example burning sugar results in a chemical reaction because the properties of cube B changed when it was burned. This change in solubility shows that cube B must be a different substance than cube A because of the chemical reaction that occurred when cube B was burned.

3. Consider the technology behind each type of
microscope. Why can light microscopes produce
images in their natural color, while scanning
electron and transmission electron microscopes
only produce grayscale images?
Answer:
See the answer below
Explanation:
The light microscope uses visible light to produce images of objects on its slide while the electron microscope uses beams of electrons to project the image of specimens. Color is a property of photons of light, hence, the light microscope is able to produce images of specimens in their natural colors
The areas of the specimen on an electron microscope in which the beams of electron pass through usually appear white while other areas appear black. Hence, the electron microscopes can only produce grayscale images of specimens unless a false color is added to make the images visually appealing.
Scanning electron and transmission electron microscopes only produce grayscale images because electrons do not have colors.
Electrons can emit energy in the form of light when they return to a lower energy level. The color depends on the difference in energy between the two different levels.The color is a property of light, thereby light microscopes that use visible light to generate images can produce colored images.Conversely, scanning and transmission electron microscopes use an electron beam to image a sample, which does not record any color value.In conclusion, scanning electron and transmission electron microscopes only produce grayscale images because electrons do not have colors.

describe what isomer are and how they apply to carbohydrates
Answer: they all have the same chemical formula but differ structurally and chemically. Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond.
Explanation:
The phenomenon of exhibiting similarity in the chemical formula but differs in the compound’s structure is termed isomerism. The particular compounds that exhibited such similarity are referred to as isomers.
Isomers are classified into two major categories namely structural and stereoisomers. Isomers apply to carbohydrates that are described as follows:
Glucose, fructose, and galactose are some of the examples of monosaccharide isomers They all tend to have the same chemical formula but they are varied in terms of structure and chemical nature.Thus, we can conclude that the isomers have the same molecular formula but varying structures. Further, how the isomers apply to carbohydrates is also discussed.

what is the charge of an ion with 16 protons and 14 electrons? helppppppp
Answer:
Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32. Because the ion has 16 protons and 14 electrons, its net charge is 2–. Thus, the symbol for the ion is 32S2–.
Explanation:
The charge of an ion with 16 protons and 14 electrons is positive.
What is an ion?An ion is a gross electrically charged atom or a molecule. By convention, the charge of an electron is considered to be negative, and this charge is equal to and opposite to the charge of a proton, which is considered to be positive.
Ions are formed by adding or removing electrons from neutral atoms, molecules, or other ions; or by combining ions with other particles.
When atoms gain or lose electrons, ions form. Because electrons are negatively charged, losing one or more electrons causes an atom to become positively charged.
Gaining one or more electrons causes an atom to become negatively charged. The attraction between positively and negatively charged ions is known as ionic bonding.
Thus, the ion here is positive as it have more protons than electron.

What happens to the glucose produced in photosynthesis? Select ALL that apply a The glucose is modified & stored in the plant for later use b The glucose is used directly as energy by the chloroplast c The glucose is moved to the mitochondria where it will be converted into energy d The glucose is released as a waste product
Answer:
The glucose produced in photosynthesis is altered and processed for later use in the plant. The glucose is used directly by the chloroplast as energy. The glucose is transferred to the mitochondria to be transformed into energy.
Explanation: Among the four statements, three of the statements are correct . The fourth statement which states that "the glucose is released as a waste product " is incorrect . This is because oxygen is used as the waste product rather than glucose.
All the three statements are correct about glucose in photosynthesis . The plant uses glucose, with most of it transformed into other carbohydrates, such as starch and cellulose.
A mechanism in which, in the mitochondria of all cells, chemical energy (glucose) is converted into an energy currency (ATP). Glucose and oxygen are converted into water and carbon dioxide. There are two forms namely, aerobic which requires oxygen and Anaerobic which does NOT require oxygen.
Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide to make glucose and release oxygen.
The use of glucose produced during photosynthesis is:
a. The glucose is modified & stored in the plant for later use
b. The glucose is used directly as energy by the chloroplast
c. The glucose is moved to the mitochondria where it will be converted into energy
Glucose pathway in plants:
Glucose is the primary source of energy, which is stored in the form of starch. The glucose is broken down through cellular respiration to yield ATP. Glucose is directly used as a source of energy by chloroplasts. Chloroplasts require glucose to convert light energy into chemical energy to carry out photosynthesis. Mitochondria are the powerhouse of the cells, which converts glucose into ATP via cellular respiration. The glucose and oxygen are converted into water and carbon dioxide.To know more about the roke of glucose in photosynthesis, refer to the following link:

You have identified a plant in your garden with a new flower color. You want to determine if this phenotype is dominant or recessive. Which cross would tell you this? You have identified a plant in your garden with a new flower color. You want to determine if this phenotype is dominant or recessive. Which cross would tell you this? crossing the new plant to one you know has the dominant trait crossing the plant to one you know has the recessive trait selfing the plant sequencing the DNA for the trait crossing the plant to a plant of the same type of any color
Answer:
crossing the plant to one you know has the recessive trait
Explanation:
The correct procedure would be to cross the identified plant with the same plant that has the recessive trait.
The phenotypes of the progeny from the cross will give an indication of the dominance or recessive of the phenotype. If all the progeny from the cross produce the same flower color as that of the identified plant, it means the phenotype is dominant. Otherwise, it is recessive.
The procedure is called test-crossing in genetics.
Define sickle cell.
Who is a sickler?
Answer:
Sickle cell disease is an inherited blood disorder that turns normal, round blood cells into misshaped cells that look like sickles or crescent moons. These sickled cells can get stuck in blood vessels, blocking blood flow and causing severe pain as well as damage to organs, muscles, and bones. Sickle cell disease is inherited, passed from parent to child. Children with sickle cell disease have two defective genes, one from each parent. A child born with sickle cell trait inherited one defective gene from one parent, and a normal gene from the other parent. These children don't have sickle cell disease but are carriers of the defective gene and may pass it on to their children.

What are electron energy levels? Where are they located?
The electrons surrounding an atom are located in regions around the nucleus called “energy levels”. An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be. The first energy level is closest to the nucleus.
Answer: Located in regions around the nucleus.
Explanation: Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. As you go farther from the nucleus, electrons at higher energy levels have more energy. The electron energy levels are an atom located in regions around the nucleus. An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be. The first energy level is closest to the nucleus. The second energy level is a little farther away than the first.
