Answer:
B. Ethanol
Explanation:
During absence of O2 pyruvic acid is reduced to ethanol in alcoholic fermentation.
Answer:
C. root
The part of the plant that absorbs nutrients and water is root.
Hope it will help :)
Answer:
-1.9mL/min
Explanation:
The rate of O₂ production can be calculated by the formula
= ( Final volume - initial volume)/time(min).
From the graph provided and attached below, the rate of O₂ production or rate of photosynthesis at light intensity of 8 is about 3.75 mL/min.
The rate of O₂ production is taken as the rate of photosynthesis. It is expected to progressively increase from light intensity 0 as light intensity increases. However, at very high light intensity, the rate slows down as water becomes limiting and the stomata closes in order to conserve water.

Experiment 2: Respiration in the Dark
Calculate the volume change for respiration in the dark. As you already saw from earlier questions,
oxygen production is fairly constant. You will not need to calculate the individual volume changes.
Just subtract the original volume at 00:00:00 from the final reading at 00:02:00. Record your answer
for use in a later question.
<em>Note: depending on when you started the timer there is a range of possible answers. Pick the answer that is closest to this</em>
What was the volume change for respiration in the dark?
Correct answer:
-1.9 mL/min
Answer:
The placenta is a unique vascular organ that receives blood supplies from both the maternal and the fetal systems and thus has two separate circulatory systems for blood: (1) the maternal-placental (uteroplacental) blood circulation, and (2) the fetal-placental (fetoplacental) blood circulation. The uteroplacental circulation starts with the maternal blood flow into the intervillous space through decidual spiral arteries. Exchange of oxygen and nutrients take place as the maternal blood flows around terminal villi in the intervillous space. The in-flowing maternal arterial blood pushes deoxygenated blood into the endometrial and then uterine veins back to the maternal circulation. The fetal-placental circulation allows the umbilical arteries
