Complete the blanks by matching with one of the given terms - A molecule moves down its concentration gradient by passive transport, but requires transport to move up its concentration gradient. - Transporter proteins and ion channels function in membrane transport by providing a pathway through the membrane for specific polar solutes or inorganic ions. - are highly selective in the solutes they transport, binding the solute at a specific site and changing conformation so as to transport the solute across the membran

the way that the mass of carbon can be conserved through cellular respiration is through a process/law called the law of conservation of mass which even tho it undergoes a process, mass is not be destroyed or changed

answer: a) a compound microscope has a greater magnification ability than a simple microscope.

explanation:

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
