Answer:
The answer to the question is A
Explanation:
The main indicator of a woody plants age like trees are the amount of rings inside, for example if a tree had twenty rings the tree would be twenty years old.
Answer:
Adhesion and cohesion
Explanation:
Capillary action refers to the ability of water to move in small-diameter or narrow tubes against the force of gravity. Water has a tendency to form hydrogen bonds with other water molecules.
Intermolecular hydrogen bonding allows the water molecules to stick together. This tendency of water molecules to stick together is called cohesion. Adhesion is the ability of the water to stick to other substances with polar or charged groups. As a consequence of cohesive and adhesive properties, water exhibits capillary action. When water moves through microscopic spaces present between the soil particles towards the roots, it is capillary action.
B. pyruvate
C. lactic acid
D. ethyl alcohol
Answer:
The correct answer is B. pyruvate
Explanation:
In glycolysis, glucose is oxidized to produce 2 molecules of NADH, ATP, and pyruvate. Then this pyruvate molecule is used in the Kreb cycle and gets fully oxidized into carbon dioxide and water.
This oxidation of pyruvate molecule gives rise to more NADH and FADH₂ molecule. These molecules are reduced form of energy which is used as a source of electron during oxidative phosphorylation to produce more ATP molecules.
Therefore pyruvate is the useful product of glycolysis which is utilized to give energy to the cell in the form of ATP.
Answer: Therefore, the correct answer is: Waves are seen to approach the beach at an angle.
Explanation:
An observation in science refers to a direct and factual statement based on the information gathered through the senses or measurements. Among the given options, the following statement would be considered an observation:
"Waves are seen to approach the beach at an angle."
This statement describes something that can be directly perceived or measured by observing the behavior of waves as they move towards the beach. It is a factual and observable phenomenon that can be witnessed and documented.
On the other hand, the remaining options involve explanations or concepts rather than direct observations. They provide information about the causes, effects, or mechanisms behind waves, but they do not describe something that can be directly observed or measured. These options involve interpretations, explanations, or generalizations based on scientific knowledge, rather than direct sensory or measurable data.
Answer:
Genetics is a branch of science that deals with the study of genes, their sequence, function, variation, and heredity.
Increasing understanding of genetics help in making new fields of health care, for example,
Answer;
c. It led to the development of contact-inhibition regulators.
Explanation;
-While normal cells possess mechanisms that inhibit proliferation when conditions are inappropriate, tumor cells circumvent these mechanisms and continue proliferating.
-Contact inhibition is a process of arresting cell growth when cells come in contact with each other. As a result, normal cells stop proliferating when they form a monolayer in a culture dish. Contact inhibition is a powerful anticancer mechanism that is lost in cancer cells.
