What are some of the limitations that natural selection has on the ecosystem?

1 answer:

4 0

Limits to variation The most obvious limit to natural selection is that suitable variation may not be available. This may be because certain phenotypes cannot be built, being ruled out either by physical law or by the properties of biological materials.

The equation that shows the decomposition of silver carbonate are;

2Ag2CO3 ---------> 4Ag + 2CO2 + O2

From the periodic table:

Mass of silver = 107.8682 grams

Mass of carbon = 12 grams

Mass of oxygen = 16 grams

Molar mass of Ag2CO3 = 2(107.8682) + 12 + 3(16) = 275.7364 grams

From the balanced equation above:

2(275.7362) = 551.4728 grams of Ag2CO3 produces 4(107.8682) = 431.4728 grams of Ag

Thus, in order to know the mass of Ag produced from 2.76 grams of Ag2CO3, we'll use the cross multiplication method;

Mass of Ag produced = (2.76 × 431.4728) / (551.4728) = 2.16 grams

Based on the calculations demonstrated above, the law of conservation of mass is applied.

A good example of homeostasis would be: darkening a room makes it easier to sleep. ingesting too much alcohol leads to vomiting.

solmaris [256]

Homeostasis is a self-regulating technique by which systems in the body maintain stability and tend to adjust to optimal conditions which are essential for survival. Thereby, the role of homeostasis is to help the body maintain constant internal environment. A good example of homeostasis would be ‘drinking excess alcohol causes vomiting’.

List the Kingdoms that are unicellular ONLY (2 answers

Mumz [18]

Answer:

Prokaryotes or unicellular organisms, without a nucleus, are categorized in two different kingdoms: Eubacteria and Archaebacteria or simply, bacteria and archaea, respectively. Sometimes these two kingdoms are also clubbed together as Monera. Unicellular organisms with a nucleus are part of the kingdom Protista.
