Photosynthesis is measured by the amount of oxygen produced. Counting pondweed bubbles or using the Audus apparatus to determine the amount of gas evolved over time can both be used to quantify oxygen.
<h3>
What is photosynthesis?</h3>
Photosynthesis is the conversion of light energy into chemical energy by green plants and other organisms. Light energy is collected and utilised by green plants during photosynthesis to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.
The forming bubbles are either counted or recorded using light barriers, which is difficult due to their small size and frequently changing ascent velocity. When gas bubbles produced during photosynthesis by aquatic plants leave the plants, they produce different sound pulses.
B. Because the gas collected contains water vapor in addition to oxygen, it is not pure oxygen.

The answer is option D "test the effect of cyanide on algae." Ecologist are researchers who study how organisms interact with their environment so in this case they are testing how algae reacts to cyanide. In another example they will be testing how a ape reacts to having a different fruit tree in their habitat. It wouldn't be option A, B, and C because you have to remember the job of a ecologist and the options are not jobs of one.
Hope this helps.
Answer:
some of the weak-acid component of the buffer will dissociate and turn into the conjugate base (which is the weak-base component of the buffer) thus replenishing most of the protons removed.
Positive, because there are more protons (positive) than electrons (negative) and neutrons are neutral
Answer:
Interphase is the basic phase of cell cycle.
Explanation:
Interphase is the non-dividing phase. It happens between two successive M phase. Interphase is preparatory phase during which the cell prepares for the next cell division and grows to the same size as their mother cell. This phase is further divided into three sub-phases: i) G1 phase- interval between mitosis. DNA replication begins here. It is the first growth phase, RNA and protein get synthesized. ii) S-phase- Synthesize of DNA takes place and chromosome gets duplicated. iii) G2 phase-
Pre-mitotic phase or the second growth phase. it prepares the cell for the next cell division.
