Hi! :")
Hypothesis: Recommended explanation of the case taken as a starting point for further investigation.
Theory: The explanation obtained by the scientific method and which has a solid foundation that is tested and approved through observation and experiments.
Difference: Theory is not predicted in any field The accuracy of the same big bang theory is unknown.. However, the hypothesis is still under investigation and proof.
Good Luck ;)

Answer:
Specialised cell type Animal or plant cell? Function
Phloem cell Plant The building block of the transport system for sugars
Xylem cell Plant The building block of the transport system for water and mineral salts
Explanation:
<span>One of the key ideas in biology is that structure always impacts function. For one, a neuron has a long axon because it helps to transmit signals from cell to cell, allowing the nervous system to function. Secondly, epithelial cells are long and thin, which allows them to cover numerous organs in the body. Finally, muscle cells are more rod-shaped and are comprised of contractile units which allows them to withstand the wear and tear of muscle movement.</span>
Answer:
The correct answer will be option-D
Explanation:
Pulmonary Surfactant is a complex substance produced by the pneumocytes epithelial II cells in the alveolar sac.
The surfactant is composed of the proteins and lipids which plays a role in keeping alveoli open by reducing the surface tension formed between the air and liquid.
The surfactant act by forming a monolayer surface film which helps reduce the surface tension.
Thus, option-D is the correct answer.
