I believe the answer is C. I could be wrong and it may be B
Answer:
Hydrophilic heads facing exterior
Hydrophobic tails facing interior
Explanation:
In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.
Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.
The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.
The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
Answer:
Anthropogenic biomes, also known as anthromes, human biomes or intensive land-use biome, describe the terrestrial biosphere in its contemporary, human-altered form using global ecosystem units defined by global patterns of sustained direct human interaction with ecosystems.

Arteriosclerosis is characterized by thickening of the tunica intima and loss of elasticity in the tunica media.
Answer:
The organism is anaerobic bacteria.
Explanation:
Bacteria is a prokaryotic microorganism that have different shapes and can inhabit in different habitat regions.
Bacteria is an important factor in the ecosystem as they have some unique features like they can capable of recycling vitamin B₁₂ and provide it through the food chain.
It play a vital role in nitrogen cycle as they helps to fix nitrogen in the ecosystem which is obtianed by plants and animals for their growth and development.
Methanogenesis is a process of formation of methane in the environment by some microbes like anaerobic bacteria through the process of anaerobic respiration.
