Answer: The monosaccharides that are correctly paired with their class are (A) fructose : hexose ketose, (C) glyceraldehyde : triose aldose and (F) dihydroxyacetone : triose ketose.
Explanation: Monosaccharides are classified into two: aldose and ketose. In open chain form, monosaccharides have unbranched chains in which all the carbon atoms are linked by single bonds, one of the carbon atoms is double bonded to an oxygen atom to form a carbonyl group and each carbon atom has a hydroxyl group. An aldose is a monosaccharide in which the carbonyl group is at the end of the carbon chain while a ketose is a monosaccharide in which the carbonyl group is at any other position. A triose is a sugar with three carbon atoms, sugars with four, five, six and seven carbon atoms are known as tetrose, pentose, hexose and heptose respectively.
Fructose is a hexose ketose, erythrulose is a tetrose ketose, glyceraldehyde is a triose aldose, erythrose is a tetrose aldose, ribose is a pentose aldose while dihydroxyacetone is a triose ketose.
It was believed that a asteroid hit the Earth (specifically Mexico) when the asteroid hit it caused a freezing darkness due to dust and debris being kicked up by the asteroid . The dust and debris blocked the sunlight causing a temperature drop.
B. Is characterized by four different zones.
Answer: <u>The Plant Cell would die</u>
<u />
Explanation: Although the <u>Mitochondria</u> is unharmed the <u>Plant Cell</u> still needs the<u> Chloroplasts</u> because they are responsible for <u>Photosynthesis </u>which gives the plant energy, And without the Chloroplast ,Photosynthesis cannot be started
We can rule out small fish and grasses. My guess is that zooplankton get their energy from phytoplankton, because phytoplankton use photosynthesis to get their energy.
