I'm pretty sure the answer would be A. Chromosomes contain one or more genes.
Answer:
<u>Motor neurons </u>send messages to the muscles and glands to respond to stimuli.
<u>Sensory neurons </u>move information towards the central nervous system for processing.
<u>Interneurons </u>carry information from one type of neuron to another.
Explanation:
- Neurons are basic structural and functional units of Nervous system.
- Neurons possess electrical excitability, the ability to respond to a stimulus and convert it into a action potential.
- Neurons can be classified on the basis of their structure and function.
- On the basis of structure neurons are classified as, Multipolar neuron;Bipolar neuron; Unipolar neuron.
- On the basis of function neurons are classified as, Afferent or sensory neuron; Efferent or motor neurons; Interneurons or association neurons.
Answer:
Number 1. the flower; it has a reproductive function. They are the reproductive organs of the plant. They mediate sperm contained within pollen, to the ovules contained in the ovary.
Number 2. the leaf; their primary function is photosynthesis -manufacturing food for plants
Number 3. the stem; it's function is to provide support for leaves and flowers, they conduct water and nutrients from the roots and food in the form of glucose from the leaves to other plant parts.
Number 4. the roots; their function is to absorb water and minerals from the soil, anchor the plant in the soil and to store extra food for future use.

Answer: The correct answer is salt.
A compound is a chemical substance which is formed by the combination of two or more elements, joined together in a fixed proportion.
Salt is a chemical compound which is formed by the reaction of an acid with a base. For example- NaCl ( sodium chloride) is a common salt. It is formed by the combination of two elements. Therefore, salt is a compound.
On the contrary, Phosphorous (P), sulfur (S) and Oxygen (O₂) are composed of a single element. Therefore, they are not compounds.
Thus, the correct answer for the compound is Salt
