explain selective breeding, including why selective breeding is not a change caused by natural selection
SCORPION-xisa [38]
New varieties. Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.

What is the maximum mass of S8 that can be produced by combining 77.0 g of each reactant?
g100num [7]
The balanced equation is
<span>8SO2 + 16H2S ----> 3S8 + 16H2O
</span>so
77g SO2 / 64g/mole = 1.203moles  of SO2 
<span>77g H2S / 34g/mole = 2.26moles  of H2S 
</span>now 

<span>1.203 moles SO2 yields 3/8x amount that is = 0.456moles  of S8 
</span>so
<span>2.06moles H2S yields 3/16x amount = 0.386moles of S8 
</span>hence
H2S = produce  only 0.386moles  of S8 = 98.98g S8
hope it helps

The (matrix / stoma / cytoplasm / nucleolus) is the innermost compartment of a (cytoplasm / cell wall / mitochondrion / nucleus)
Olin [163]

Answer:

Matrix, Mitochondrion, Kreb's cycle, Pyruvic acid

Explanation:

The above question illustrates aerobic cellular respiration, specifically the second stage called Kreb's cycle or Citric acid cycle. This process occurs in the inner membrane of the mitochondrion of eukaryotic cells called MATRIX.

It occurs when the pyruvic acid produced during Glycolysis (first stage of cellular respiration that occurs in the cytoplasm) is converted to Acetyl CoA in order to enter the citric acid cycle in the mitochondrion. The Acetyl CoA is then used in a series of reactions that comprises of reduction-oxidation, hydration, dehydration, and decarboxylation.

This reactions involving 8 steps converts the Acetyl CoA (from pyruvic acid) to 2 molecules of CO2, 1 molecule of GTP/ATP, and electron donors NADH2 and FADH2.
