Mass flow is the movement of dissolved nutrients into a plant as the plant absorbs water for transpiration. The process is responsible for most transport of nitrate, sulfate, calcium and magnesium. Diffusion is the movement of nutrients to the root surface in response to a concentration gradient.
OB. A smaller ion
OC. A covalent bond
OD. An ionic compound
Answer:D. An ionic compound
Explanation:
An ionic compound by a complete transfer of valence electrons from an atom of a metal to an atom of a non metal so that both can attain a stable duplet or octet structure of noble gases. Potassium has 19 electrons with one valence electron while chlorine has 17 electrons with 7 valence electrons. Potassium will transfer its valence electron to chlorine atom, resulting in potassium having one positive charge and chlorine have one negative charge with both attaining a noble octet structure of noble gases. The compound formed is an ionic compound because it involves a positively charged potassium ion and a negatively charged chloride ion.
Answer:

The sense organs contain receptors that are sensitive to stimuli.
The nervous system consists of the central nervous system - brain and spinal cord -and peripheral nerves. Nerve impulses travel through the axons of neurones - nerve cells. Reflex actions are fast, automatic and protective responses.
Human vision is binocular, which gives us a good perception of depth. Vision defects include short-sightedness, long-sightedness and colour blindness.
