What is a snake that eats a mouse an example of?
predation
competition
mutualism
parasitism
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.

Answer: it's the 3rd one " the brown rabbit in parental generation heterogeneous for the fur color trait." because the brown rabbit is dominant and the black rabbit is recessive.
Explanation:
List the following events in the order they occur: _____ a. The motor end plate is depolarized. _____ by. The sarcomeres contract. _____ c. Acetyl choline is released from the axon terminal into the synaptic cleft. _____ d. The depolarization triggers an action potential which propagates along the sarcolemma and the T tubules. _____ e. An action potential arrives at the axon terminal
The answer is what follows:
-An action potential arrives at the axon terminal.
-Acetyl choline is released from the axon terminal into the synaptic cleft.
-The motor end plate is depolarized.
-The depolarized triggers an action potential with propagates along the sarcolemma and the T tubules.
-The sarcomeres contract.

A certain sugar has no change in color when tested with Benedict’s solution. Can you tell what type of sugar it is? Explain.
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.

Construct an explanation for that carbon hydrates are considered as a source of energy for the human body. Justify your answer with an evidence with your own words.
Please help out I’ll mark as brainlist
Explanation: Carbohydrates are mainly composed of Oxygen, Carbon and Hydrogen. the most popular carbohydrate that is compatible with the human body is glucose which is the final result of every Carb we take in. a glucose molecule has 6 carbon atoms. during glycolysis, a single glucose molecule is broken down into two pyruvate molecules. in there, the first couple of ATP is synthesized. at later steps of the cycle, more ATP molecules are reduced.
(ii) Describe an experiment he could carry out to show that auxin causes bending of a
shoot.
Answer:
Illumination results auxin moving to the dark side of stem tips. As this auxin diffuses down the dark side of the stem, the cells respond by enlarging. This causes the plant to bend toward the light.
A student observes a reaction with an enzyme in a beaker. If nothing is removed from the beaker containing the reaction, what is the only thing the student must add to start the reaction again?
A.acids
B.enzymes
C.products
D.substrates
Answer:
90% Products, 10% Acids
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.

which type of transport would be required for the solute molecules to move against the concetration gradient?
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.
