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.

Which would most likely be joined by an ionic bond?
KATRIN_1 [288]
An ionic bond is composed of a cation and anion, which are charged ions. You cannot have atoms with ionic bonds, because there is no opposite attraction between charges due to atoms having a net nuclear charge of zero. Therefore, a cation and anion would most likely be joined by an ionic bond.

If 1.38×1022 atoms of element y have a mass of 1.50 g, what is the identity of y? express your answer as a chemical symbol.
zaharov [31]
1,38×10²² = 0,138×10²³

0,138×10²³ ----- 1,5g
6,02×10²³ ------ X
X = (1.5×6,02×10²³)/0,138×10²³
X = 65,435 g/mol

It's ZINC (Zn)
