Answer:
diversity of species increases the ability of ecosystems to do things like hold soils together, maintain soil fertility, deliver clean water to streams and rivers, cycle nutrients, pollinate plants (including crops), and buffer against pests and diseases—these are sometimes called 'ecosystem functions' or 'ecosystem.
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between
species, and of ecosystems.
explanation:
Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention
Answer:
Bases and Acids are chemically opposite from each other,and there are multiple ways to distinguish how they react when dissolved in water.
Explanation:
You have 1 m³ of wood and 1 m³ of aluminum.
Aluminum is the heavier material with a higher density.
What is density?
The mass-to-volume ratio, or mass per unit volume, is known as density. It assesses how much material an object contains in relation to its volume (cubic metre or cubic centimeter). In essence, density is a measurement of how closely together matter is packed.
<u>Density of the wood =1500kg/1m³ = 1500kg/m³ ⟹ 1m³ has a mass of 1500kg Density of Aluminum(Al) =2700kg/m³ = 2700kg/m³⟹ 1m³ has a mass of 2700kg </u>
Therefore, Aluminum is the heavier material with a higher density.

The answer would be B. 17 g because nitrogen's approximate mass is 14, adding to that 3 because of the three hydrogen's adds up to 17.
Answer:
D) both groups are equatorial.
Explanation:
To solve this question we can start by drawing the molecule in using the <u>structure of the hexagon</u>. In this structure, we have the methyl group on carbon 1 and the terbutyl group on carbon 3, additionally, if we have a cis structure both groups must have the same type of bond (in this case the wedge bond). (See figure 1)
When we write the <u>chair structure</u>, we must keep the same structure. That is, methyl must be on carbon 1 and terbutyl on carbon 3. Also, the cis configuration must be maintained. With this in mind, we can choose the <u>equatorial configuration</u> for methyl on carbon 1 (since the position equatorial is the one that has <u>less steric impediment and more stability</u>). If this is true for carbon 1, we must place the terbutyl group on carbon 3 in the same configuration (i.e. cis). Therefore, on carbon 3 we must place the tert-butyl down on carbon 3, that is, in the <u>equatorial position</u>. (See figure 1).
Therefore, in the chair-like structure, both groups must be in an equatorial position.
I hope it helps!
