C.) 45 AND 75............
Answer:
D) The addition of different substances affects the freezing point of water.
Explanation:
The best answer would be letter D.
The short explanation would be, the other choices only involves the addition of 1 substance (salt or sugar).
The long explanation:
Susie is testing two types of solution: <u>sugar + water</u> and <u>salt + water. </u>This means that she is testing the effect of both. An experiment is done to test certain variables and an addition of a variable that is not being tested is not advisable. But since she intentionally used both solutions, then it is reason enough to assume that she is testing both substances (sugar and salt) so the hypothesis should include both as well.
Answer:
In the light-independent reactions, the plant starts with carbon dioxide and ends up with glyceraldehyde-3-phosphate (G3P). It uses ATP and NADPH from the light-dependent reactions as energy sources
Explanation:
<em>Step 1</em>: CO₂ adds to ribulose biphosphate (RBP) to form a six-carbon sugar that immediately decomposes into two molecules of 3-phosphopglycerate (3-PGA).
CO₂ + RBP ⟶ 2 3-PGA
<em>Step 2</em>. A phosphate group adds to the 3-PGA to form 1,3-biphosphoglycerate (1,3-BPG).
3-PGA + ATP ⟶ 1,3-BPG + ADP
<em>Step 3</em>. NADPH reduces the 1,3-BPG to G3P
1,3-BPG + NADPH ⟶ G3P + NADP⁺
Most of the G3P is regenerated into RBP, but some leaves the cycle to become glucose.
