Of these conditions, the ones that made it beneficial for aquatic plants to move onto land would be "<span>a. bright sunlight, abundant CO2, and lack of competitors</span>"
<span>Na is the chemical symbol for sodium. Na+ is formed when sodium loses an electron from its outer shell (the number of electrons and protons is now unbalanced, giving an overall positive charge) and becomes a sodium ion. Losing an electron happens when a metal reacts with a non metal.</span>

Answer:
<em>Endothermic reactions: separation of solute molecules , separation of solvent molecules</em>
<em>Exothermic: formation of solute-solvent interactions</em>
Explanation:
An endothermic reaction can be described as a reaction which requires energy. Usually, the energy is taken in the form of heat from the environment. For example: the separation of solute and solvent molecules.
An exothermic reaction can be described as a reaction in which energy is released during a reaction. For example, a solute and a solvent reaction. Energy is usually released in the form of heat during an exothermic process.
Answer:
Modified apocrine sweat glands
Explanation:
The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.
As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.
This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.
