- If a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be?
Answers
Answer:
If 0.9% NaCl were isotonic to a cell then anything greater than 0.9% would be hypertonic. A hypertonic solution is one which has a greater concentration of dissolved solutes while an isotonic one has a similar concentration of solutes.
Explanation:
If a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be 1.0%. Thus, the correct option for this question is D.
What is a Hypertonic solution?A hypertonic solution may be defined as a type of solution that significantly has lower osmotic pressure than another solution to which it is compared. If the surrounding solution has a higher solute concentration compared to inside the cell, it represents a hypertonic solution.
According to the context of this question, if a 0.9 % salt solution is isotonic to an animal cell, then anything greater than 0.9% would be hypertonic. So, all the options except for 1.0% are lesser than or equal to 0.9%.
Therefore, if a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be 1.0%. Thus, the correct option for this question is D.

we use to digest food.
Answers
Answer:
The digestive system is made up of the alimentary canal (also called the digestive tract) and other organs, such as the liver and pancreas. The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus.
In mammals, the digestive tract is made up of multiple organs such as the stomach, pancreas, and intestines. These all work together to form the alimentary canal we use to digest food.
The digestive system in mammals is a complex network of organs and structures responsible for breaking down food into nutrients that can be absorbed and utilized by the body. The digestive tract, also known as the alimentary canal or gastrointestinal tract, consists of several organs that collaborate to facilitate the digestion and absorption process.
Stomach: The stomach is a muscular organ that receives and churns food, mixing it with gastric juices containing enzymes and acids to begin the process of digestion. It plays a crucial role in breaking down proteins.
Pancreas: The pancreas is both an endocrine and exocrine gland. Its exocrine functions involve producing digestive enzymes that are released into the small intestine to further break down carbohydrates, proteins, and fats.
Mouth: The mouth is where food is chewed and mixed with saliva. Saliva contains enzymes that start to break down carbohydrates.
Esophagus: The esophagus is a muscular tube that carries food from the mouth to the stomach.
Small intestine: The small intestine is the longest part of the digestive tract. It is where most of the nutrients from food are absorbed.
Large intestine: The large intestine is shorter than the small intestine. It absorbs water and salts from food and stores waste products until they are eliminated from the body.
Rectum: The rectum is the last part of the digestive tract. It stores waste products until they are eliminated from the body.
The digestive tract is a vital organ system that is essential for the survival of mammals. It allows mammals to obtain the nutrients they need from food to stay alive and healthy.

Answers
Hi! Your answer is glucose.
What exactly is glucose? It originates from Greece, where it translates to "sweet." It's a type of sugar.
Good luck on your science!
The sun helps plants transform carbon dioxide into a simple carbohydrate called glucose.
What is carbohydrate?Sugar molecules make up carbohydrates, or carbs. Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats.
Glucose is created by your body's breakdown of carbs. The primary source of energy for the cells, tissues, and organs in your body is glucose, sometimes known as blood sugar.
In the oxidation-reduction process known as photosynthesis, carbon dioxide is reduced to carbohydrates and water is oxidized.
The process by which light energy is transformed into chemical energy in the form of sugars is known as photosynthesis. Using light energy, glucose (or other sugars) are created from carbon dioxide and water, with oxygen being released as a byproduct.
Thus, the carbohydrate called glucose is formed by the reaction of sun in plants.

if a cell were placed in an isotonic environment relative to the cell, water would __.
Answers
Answer:
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell’s volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell. Tonicity in living systems
Explanation:
If a cell were placed in an isotonic environment relative to the cell, water would move across the cell in both directions, but the cell size remains the same throughout the conditions. The cell will remain flaccid.
What do you mean by Isotonic solution?
An isotonic solution may be referred to as a solution in which the concentration of water is the same as that of the cell.
If a cell resides in an isotonic solution, there will be a net flow of water into or out of the cell, but movement takes place in such a way that the volume of the cell remains the same.
Therefore, If a cell were placed in an isotonic environment relative to the cell, water would move across the cell in both directions, but the cell size remains the same throughout the conditions. The cell will remain flaccid.
