Answer:
B. DNA
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA. The information in DNA is stored as a code made up of four chemical bases: adenine, guanine, cytosine, and thymine.

Onion root cell 3 is the closest to the completion of the cell cycle. Mitosis is
the type of cell division which involves the production of two identical
daughter cells.
Telophase is regarded as the final stage of mitosis before cytokinesis takes
place. In this phase, the chromosomes decondense and the spindle breaks
down.
There is also formation of two new nuclei of the daughter cells which are
separated by the newly formed nuclear membrane which is evident in the
onion root cell 3 thus making it the most appropriate choice.

Epidemiology studies health-related states and occurrences (not simply diseases) in specific communities.Therefore, option (A) is correct.
What is epidemiology?The study and analysis of the distribution, patterns, and determinants of health and disease conditions in a given population is what epidemiology is all about. It is one of the most important aspects of public health, and it influences both policy decisions and evidence-based treatment by determining the factors that put people at risk for disease and setting goals for preventative medical care.
Descriptive, analytical, and experimental methods are the three primary approaches utilized in epidemiology. Descriptive epidemiology is the method that is utilized the most to investigate the occurrence of disease, despite the fact that all three can be employed to do so.
Therefore, option (A) is correct.

Which statement describes functions of anti bodies
Answer:
Explanation:
Antibodies have three main functions: 1) Antibodies are secreted into the blood and mucosa, where they bind to and inactivate foreign substances such as pathogens and toxins (neutralization). 2) Antibodies activate the complement system to destroy bacterial cells by lysis (punching holes in the cell wall).

what is the specific function of the structure labeled f?
Answer:
The muscle spindle indicated by F functions as a proprioceptor that is responsive to changes in the length of the surrounding muscle.
Explanation:
The specific function of the structure labeled f is proprioceptor that is responsive to changes in the length of the surrounding muscle.
What is the function of the muscle spindle?The muscle spindle is activated whenever the weight of the body, tending to bend the knees, stretches the muscles. Stimuli are sent to the spinal cord and through the motor nerve and the muscles contract to counteract the action of gravity.
The Muscle spindle is a proprioceptive sensory receptor spindle composed of muscle bundle fibers. Its main function is to signal changes in the length of the muscle on which it is located. Muscle Spindles are structures responsible for mechanical myo-integrity and regulation of muscle contraction/distension.
