sattari [20]

The correct answer is:

A. leaves and dermal

Explanation:

The dermal tissue system protects the soft tissues of plants and handles interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells comprising the younger parts of a plant. It conceals a waxy layer named the cuticle that inhibits water loss. Plant parts that become woody no longer have dermal tissue as their outer layer because it is followed by periderm or cork. Just as our own covering assists to defend our bodies, the dermal layer of a plant has the same function.

active transport and facilitated diffusion are two types of cellular transport which statement is true of both
Dovator [93]

Answer:

I believe the correct answer is both involve proteins in the cell membrane.

Explanation:

This is because Facilitated diffusion does not require any energy to transport molecules, while Active transport requires ATP. Facilitated diffusion transports molecules from an area of higher concentration to an area of lower concentration (or down a concentration gradient). Active transport moves molecules from an area of lower concentration to an area of higher concentration (or up a concentration gradient). Answer choice A is the only choice that makes sense.

Hope this helps,
