Genetic material is contained in the
- A.
Vacuoles
- B.
Cell walls
- C.
DNA
- D.
Lysomes
Correct Answer
C. DNAExplanation
Genetic material is contained in the DNA. DNA, or deoxyribonucleic acid, is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms. It is found in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. DNA is responsible for transmitting hereditary information from one generation to the next and plays a crucial role in determining an organism's traits and characteristics. Vacuoles, cell walls, and lysosomes are cellular structures or compartments that serve different functions, but they do not contain genetic material.Rate this question:

- D.
The process by which plants make their food
Correct Answer
C. The process by which traits pass from parents to their childrenExplanation
The correct answer is "the process by which traits pass from parents to their children." Heredity refers to the transmission of genetic information from one generation to the next. It involves the passing on of traits, such as physical characteristics or genetic disorders, from parents to their offspring through the transfer of genes. This process is responsible for the similarities and differences observed among individuals within a species and is a fundamental principle in the study of genetics.Rate this question:

Photosynthesis is
- A.
The process by which water is used to turn plants green
- B.
The process in which a change occurs causing animals to appear green
- C.
The process by which plants and some other organisms capture light energy and use it to make their own food
- D.
A process in which the sun heats the earth
Correct Answer
C. The process by which plants and some other organisms capture light energy and use it to make their own foodExplanation
Photosynthesis is the process by which plants and some other organisms capture light energy and use it to make their own food. During photosynthesis, plants use chlorophyll, a pigment that gives them their green color, to convert sunlight, carbon dioxide, and water into glucose and oxygen. This process is essential for the survival of plants and is responsible for producing oxygen in the atmosphere. It is not the process of turning plants green or causing animals to appear green, nor is it the process of the sun heating the earth.Rate this question:

An animal that makes it's own food is a
- A.
Producer
- B.
Consumer
- C.
Decomposer
- D.
Carnivore
Correct Answer
A. ProducerExplanation
A producer is an organism that is capable of producing its own food through photosynthesis or chemosynthesis. They are typically plants or other autotrophic organisms that convert sunlight, water, and carbon dioxide into glucose and oxygen. This process forms the basis of the food chain as producers provide energy for other organisms in the ecosystem. Therefore, an animal that makes its own food is a producer.Rate this question:
