Answer: A. O2
Explanation:
If photosynthesizing green algae are provided with CO2 containing heavy oxygen (18O), subsequent analysis will show that 18O first appears then 3-phosphoglycerate molecule produced by the algae.
Answer:
The larger electronegative oxygen atom strips the electron from one of its hydrogen atoms, leaving the proton to dissociate.
Explanation:
Water is a molecule composed of hydrogen and oxygen atoms that forms a covalent bond i.e. share electrons. However, due to the fact that the oxygen atom in a water molecule is more electronegative than the hydrogen molecule, it tends to draw electrons towards itself, leaving the hydrogen atom more positive. This causes the POLARITY of water.
To ionize means for the atoms of a compound to dissociate into electrically charged ions (positive and negative) in an aqeous solution. Water is able to ionize because the more electronegative oxygen atom draws the electron from one of its hydrogen atoms, leaving the proton (H+) to dissociate.
Answer:
A solid has a definite volume and shape, a liquid has a definite volume but no definite shape, and there is no definite volume or shape of a gas. Usually, the transition from solid to liquid does not change a substance's volume substantially.
Explanation:
Nuclear reactions Alpha reactions
Answer:
pancreatic amylase, lingual amylase, intestinal amylase
Explanation:
When considering a sugar drink, the enzymes involved in its digestion are first the alpha amylase found in saliva, responsible for degrading starch molecules, thus generating unique molecules of monosaccharides. Then the ones in charge of continuing with the digestion will be the pancreatic amylase and the intestine at the duodenal level.
