- 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.

What is a snake that eats a mouse an example of?

Answers
Answer:
Predation
Explanation:
A snake that eats a mouse an example of predation.
A snake that eats a mouse is an example of predation. Predation is an ecological interaction where one organism (the predator) kills and eats another organism (the prey). Hence option A is correct.
What is predation?Predation is an ecological interaction between two organisms in which one organism (the predator) hunts, kills, and eats another organism (the prey). It is a form of consumption where the predator obtains nutrients and energy from the prey, while the prey is typically harmed or killed in the process.
In this case, the snake is the predator and the mouse is the prey. Predation is a natural and common interaction in many ecosystems, and it can have significant effects on population dynamics and community structure.
It can help regulate prey populations, prevent overgrazing, and promote species diversity.
Predators have evolved various adaptations to catch and kill their prey, while prey has evolved various defenses to avoid being eaten, such as camouflage, warning coloration, and physical or behavioral defenses.
Hence option A Predation is correct.

Answers
Answer:
Human cells contain two sets of chromosomes, one set inherited from each parent. Each cell normally contains 23 pairs of chromosomes, which consist of 22 autosomes (numbered 1 through 22) and one pair of sex chromosomes (XX or XY). However, sperm and ova normally contain half as much genetic material: only one copy of each chromosome. Each chromosome contains many genes, the basic physical and functional units of heredity.

which type of transport would be required for the solute molecules to move against the concetration gradient?
Answers
Answer:
Active Transport
Explanation:
active transport
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Explanation:
enzymes are not consumed in a reaction. they remain mixed with reactants. if all products have reacted in the reaction and there's nothing left, the answer is products.
But acids promote chemical reactions at certain incidents. especially if it's an essential compound to the reaction.
Ex-: Sucrose is hydrolysed to Fructose and glucose by heating with an acid. but using sucrase, the same can be done.

A certain sugar has no change in color when tested with Benedict’s solution. Can you tell what type of sugar it is? Explain.
Answers
Answer:
a certain sugar has no change in color when tested with benedict solution. can you tell which saccharide it is? no because it could be poly or disaccharide. what is the chemical formula for a polysaccharide molecule that contains 4 glucose molecules?
Sucrose
Sucrose (table sugar) contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose undergoing isomerization to an aldehyde, or fructose to alpha-hydroxy-ketone form. Sucrose is thus a non-reducing sugar which does not react with Benedict's reagent.
Explanation:
Sugars which give no color in Benedicts test are non-reducing sugars. Sucrose, a non reducing sugar does not undergo a color change in Benedict's test.
What is Benedict's solution?Benedict's solution is a chemical reagent containing copper sulphate pentahydrate and mixtures of sodium carbonate and sodium citrate. It is used to test the presence of reducing sugars.
A positive Benedicts test gives color change of blue to brick red precipitate whereas, non-reducing sugars does not give a positive result.
Sucrose contain fructose and glucose, they do not reduces the copper ion in Benedict's solution because there are no free aldehydes or ketones in sucrose.
Thus, sucrose does not reduce and will not give a color change in Benedict's test.
