The answer is passive transport does not require energy and moves materials from areas of relatively higher to lower concentration.
Passive transport is a movement of ions and other atomic or molecular substances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.
Anaerobic respiration - products are lactic acid and energy

<h3>⇝ <u>Epidermis</u> :</h3>
Protective tissues includes epidermis & cork. Epidermis is basically a simple permanent tissue, protective in function. It forms one-cell-thick covering over all the parts of plant.
<h3>⇝ <u>Characteristics of Epidermis</u> : </h3>
- Epidermis is formed of living cells, arranged in a single layer.
- In aerial parts, epidermis is covered with a waterproof and noncellular waxy covering called cuticle.
- Cells form a continuous layer, but in leaves epidermis has small openings called stomata.
- Each stoma is guarded by a pair of bean-shaped guard cells which govern opening & closing of stomatal aperture.
<h3>⇝ <u>Functions of Epidermis</u> :</h3>
- Epidermis protects the underlying tissues from mechanical injury, chemicals & infection.
- Cuticle of epidermis protects against water loss & desiccation. It checks the rate of transpiration & evaporation and prevents wilting.
- Stomata in the epidermis of leaves help in gaseous exchange during respiration & photosynthesis.

Answer:
Homeostasis is the process in which the body maintains normal, healthy ranges for factors such as temperature, energy intake and growth. The <u>immune response contributes to homeostasis</u> by <u>preparing the body to fight off infection and to help the healing process in case harm occurs</u>. During infection, <u>the immune system will cause the body to develop a fever.</u> The immune system also causes an<u> increase in blood flow to bring oxygen and other immune cells to sites of infection</u>. The immune system also <u>helps wound healing, so that proper barriers in organs can be reformed such that those organs can correctly participate in homeostasis.</u>
Answer:
Fat
Explanation:
Animals rely on fat for energy during hibernation.
