Facilitated diffusion is a particular type of simple diffusion process that does not require energy intake for relatively small and larger molecules and compounds to diffuse, as the direction of diffusion is from high to low concentrations.
Answer No 1)
Natural selection tends to favour those organisms which are better adapted to live in an environment. In the case of the male pom-pom monkey, the organisms which possesses long bright puffs of turquoise fur were better adapted to live in the environment as they could keep themselves warm through insulation. As these organisms were better adapted, they were favoured by natural selection. Over time, the allelic frequencies changed and these organisms became abundant through the process of evolution.
Answer No 2)
1) We can produce other colour berries in the island of Hoi Polloi by selective breeding. In this type f breeding, we can breed the green berry plants with other coloured berry plants to get the desired results.
2) If other coloured berry plants are placed in Hoi Polloi island, then their population will increase rapidly with time.
Answer No 3)
The student was incorrect because only the genetic traits can be transferred from the parents to the offsprings. Other traits, which are acquired by the organism by living in an environment and not incorporated into the genome cannot be transferred from the parents to the offsprings. Hence, due to this, the pigs who had sharpened their tusks cannot pass these characteristics to their offsprings.

Answer:
B. removes suspended particles.
Explanation:
The first step in water treatment involves the removal of of suspended particles through the process of coagulation, sedimentation and filtration.
Coagulation process involves the addition of positively charged chemicals to the water. The positively charged chemicals neutralizes the negatively charged particles suspended in the water to form larger particles known as flocs.
The particles are then allowed to settle down through the process of sedimentation after which they are then filtered off in a process known as filtration.
