The Earth contains a great diversity of species. This:

Biology
1 answer:
True [87]2 years ago
8 0

Answer:

The correct option is A) will make no difference in the survival of life if there were major changes in the environment.

Explanation:

Due to genetic diversity, variations in species are caused which makes some organisms of a species to be better adapted than other members of the species. These variations cause organisms to survive when differences in the environment occur. Although the allele frequencies might change due to the changes in the environment but the phenomenon of genetic diversity allows life to sustain on earth even when conditions will become unfavourable.

According to Lavoisier's law, in the given reaction the mass of zinc produced will be 104 g.

Let's consider the following reaction.

Ca    +    ZnCO₃    ⇒    CaCO₃    +    Zn

64g         192 g              152 g           ? g

<h3>What does Lavoisier's law state?</h3>

Lavoisier's law states that the sum of the masses of the reactants before the reaction is equal to the sum of the masses of the products after the reaction.

mCa + mZnCO₃ = mCaCO₃ + mZn

mZn = mCa + mZnCO₃ - mCaCO₃

mZn = 64 g + 192 g - 152 g = 104 g

What would be the amount of zinc formed during the reaction?

  • The mass of zinc produced will be 104 g. TRUE.
  • The mass of zinc will be the same as that of zinc carbonate. FALSE.
  • The mass of zinc produced will be 52 g. FALSE.
  • The mass of zinc will be the same as that of calcium. FALSE.

According to Lavoisier's law, in the given reaction the mass of zinc produced will be 104 g.

What TWO factors do scientists track and monitor in all types of freshwater ecosystem?
ivolga24 [154]

Answer:

A: light availability

B: nutrients

Explanation:

Both nutrients and light availability affect the primary productivity of the freshwater ecosystem, therefore, scientists study both factors to track associated changes. This is because photosynthesis is driven by sunlight and nutrients availability. It is suggested that the abundance of autotrophs (e.g. phytoplanktons) in an aquatic ecosystem increases as light and nutrients availability increase. Thus, there will be more food available for secondary and tertiary consumers to feed upon. Resultantly, the aquatic environment will turn a biodiversity hotspot where many species of living organisms start dwelling. Thus, scientists mainly ecologists would focus on these two parameters at first that lead to consideration of other parameters.
