victus00 [196]

Answer:

Banana wafers and chips

Explanation:

Winnowing is the process of separating heavier and lighter components of a mixture by blowing air through the mixture. This implies that the relative weight of the particles in the mixture determines whether they can be separated by winnowing or not.

However, chips are heavier than wafers. wafers refer to a very light snack which is easily blown away by a current of air. Hence banana chips and wafers can be separated using the method of winnowing.

Which of the following is NOT a way that reducing biodiversity directly impacts humans?
Zepler [3.9K]

C. Fewer habitats for wild animals to live in

Explanation:

Biodiversity does not directly impact humans in that there are fewer habitats for wild animals to live in. This is a direct impact on animals and not humans.

Biodiversity is the variation of life forms in an area. It is measured by the ability of the ecosystem to sustain different life forms and keep their interaction with the environment.

It helps to maintain and sustain life.

To humans, reducing biodiversity;

  • reduces the potential of medicine derived from other organisms. When their habitat is lost, we lose them.
  • fewer ecosystems to appreciate for beauty and recreation. It leads to loss of the ecosystem.
  • fewer wild food species for humans to eat.

Loss of habitat directly affects wild animals and not man.
