Answer:
Equation
Explanation:
the last word is Equation
Considering the definition of chemical reaction and chemical equation, A chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical equation.
Chemical reactionA chemical reaction consists of the formation of new substances (products) from others (reagents). In this process bonds of the reactants are broken and new ones are formed in the products.
In other words, a chemical reaction occurs when the substances participating in it are transformed into different ones. The mass of the participating substances is the same before and after the reaction, that is, it is conserved because only a rearrangement takes place between the atoms of the reactants, which break and form new bonds.
Chemical equationChemical reactions are represented by chemical equations. In them, the reactants are determined, the products are predicted, and the proportions of the substances that participate in the reaction are indicated.
SummaryA chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical equation.

Explanation:
The almost pure cellulose obtained from the seed threads of Gossypium (cotton) is tough, fibrous, and completely insoluble in water. In contrast, glycogen obtained from muscle or liver disperses readily in hot water to make a turbid solution. Despite their markedly different physical properties, both substances are (14)-linked D-glucose polymers of comparable molecular weight. What structural features of these two polysaccharides underlie their different physical properties
Answer:
Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.
Explanation:
Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.
Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer
GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.

Answer:
false
Explanation:
hope this helps :)
It is false that individuals tend to make decisions with the elimination-by-aspects strategy as choices become more simple.
What is decision making?The process of making choices by identifying a decision, gathering information, and evaluating alternative resolutions is known as decision making.
By organizing relevant information and defining alternatives, a step-by-step decision-making process can help you make more deliberate, thoughtful decisions.
The significance of decision making is found in how it assists you in choosing between various options.
Before making a decision, it is necessary to collect all available information and weigh its pros and cons. It is critical to concentrate on steps that can assist in making sound decisions.
The ability to choose between two or more alternatives in order to achieve the best result in the shortest amount of time.

Li-Fraumeni syndrome (LFS1) is a rare hereditary disorder that leads to a predisposition to cancer. This hereditary disorder is linked to mutations in the tumor suppressor gene encoding the transcription factor p53. p53 acts at the G1 checkpoint. If damaged DNA is detected, p53 halts the cell cycle. As p53 levels rise, the production of p21 is triggered. p21 enforces the halt in the cell cycle. A variant of Li-Fraumeni, called LFS2, is thought to occur due to a mutation of the CHK2 gene, which is also a tumor suppressor gene. CHK2 regulates the action of p53. Which of the following cascades is most likely to occur in a normal cell that does not contain the LFS mutation?
Answer:
CHK2, p53, p21, cell cycle progression.
Explanation:
In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.

Explanation:
Recognize what energy is and how it is transferred throughout living systems.
Explanation:
Energy is the ability to do work. There are two main forms of energy, potential and kinetic energy.
Potential energy is the energy at rest in a body
Kinetic energy is the energy due to motion
Energy is usually transferred throughout living systems when are transformed from one form to another. For example, chemical energy in food produced by plants is taken by animals as food. They then convert the chemical energy into other forms of energy like heat energy which they use for their daily activities.when a raw, shell-less egg was placed in sugar solution the egg shrank the egg was brought back to its original size by placing it it water which process does the experiment demonstrate
Answer:
A: osmosis. The egg first expanded because it was placed in a hypertonic solution (sugar water), causing the water to exit the egg to balance the higher concentration of solute outside of the egg. Placing it in fresh water creates a hypotonic environment, thereby causing water to rush back in.

Which of the following is used for STRUCTURE and not for ENERGY?
A)glycogen which stores excess glucose consumed by animals
B)starch which stores excess glucose made during photosynthesis in plants *
C)cellulose which is difficult to break apart
Answer:
the answer is option c cellulose..
Explanation:
Cellulose is a molecule, consisting of hundreds – and sometimes even thousands – of carbon, hydrogen and oxygen atoms. Cellulose is the main substance in the walls of plant cells, helping plants to remain stiff and upright. Humans cannot digest cellulose, but it is important in the diet as fibre.
Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants as energy storage
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria. The polysaccharide structure represents the main storage form of glucose in the body.
hope it helped you and the answer is correct
The term that is used for structure and not for energy is cellulose, which is difficult to break apart. The correct option is c.
What is cellulose?A molecule called cellulose is made up of hundreds, and occasionally even thousands, of carbon, hydrogen, and oxygen atoms. The primary component of plant cell walls, cellulose, keeps plants rigid and upright.
A polymeric carbohydrate known as starch or amylum is made up of many glucose units connected by glycosidic linkages. Most green plants synthesize this polysaccharide as a form of energy storage.
Animals, fungi, and bacteria all use the multibranched polysaccharide of glucose known as glycogen to store energy. The primary form of glucose storage in the body is represented by the polysaccharide structure.
Therefore, the correct option is C) cellulose, which is difficult to break apart.

A Tomato Has A Proton Concentration Of 0.00006 M. How Would You Calculate The PH?
Answer:
Option b. is correct
Explanation:
If hydronium ion concentration [tex]H_3O^+[/tex] is given then pH is given by [tex]-log[H_3O^+][/tex]
The hydronium ion refers to the hydrogen ion in aqueous solution.
A Tomato has A Proton Concentration Of 0.00006 M
Here, 0.00006 is equal to 6 × [tex]10^{-5}[/tex]
So,
pH is given by - log [6 × [tex]10^{-5}[/tex]]

which theory states that homo sapiens began in a single geographical area and spread out from there?
a. out of africa theory
b. tectonic theory
c. multi-regional theory
Answer:
The out of Africa theory states that Homo sapiens began in a single geographical area and spread out from there.
Explanation:
A is correct because the ''out of Africa theory'' suggests that the Homo sapiens began as a species in Africa and from there it gradually spread out on the other continents across the world.
B is not correct because the ''tectonic theory'' is a theory that has nothing to do with the Homo sapiens species, but it is a theory about the movement of tectonic plates.
C is not correct because the multi-regional theory suggests that the Homo sapiens evolved into multiple regions simultaneously, not in one region only.
