Diffusion is the correct answer. Air freshening molecules spread through the room through random diffusion.
Cellular respiration takes place in the mitochondria
Answer: melanin
Explanation: Further, other cells contribute to the function of the epidermis. Melanocytes are cells that produce melanin, a compound involved in skin pigmentation produced in response to ultraviolet (UV) light exposure (6). Melanin can absorb energy from UV light to shield underlying tissues from damage.
Primary consumers (such as grazers and browsers) of the biological community will put pressure on the primary producers (these are plants) since the primary producers have limited resources (water) to reproduce due to the drought. The primary producers hence become scarce and cause the primary consumers to compete for limited resources. This causes the primary producers to reduce in population. Reduction in their population causes limited resources for secondary consumers and this cascades up the food web to tertiary consumers.
