Answer:
D. There is no enough oxygen in the culture fluid
Explanation:
The cells in the test tube need to carryout one of the important metabolic processes of living organisms - respiration. The process involves the breakdown of glucose to generate energy for other metabolic processes in the cell.
Respiration can be carried out in the presence of oxygen (aerobic) or in the absence of oxygen (anaerobic). Human cells are primarily aerobic but can carryout respiration anaerobically in the presence of inadequate oxygen.
For aerobic respiration, glucose is broken down in the presence of oxygen to produce carbon-dioxide, water and energy in the form of ATP:
<em>In the absence of oxygen, the glucose becomes converted to lactic acid and a smaller amount of ATP is produced as compared to aerobic respiration.</em>
<em>Hence, lactic acid gradually builds up in the absence of oxygen due to anaerobic respiration.</em>
The correct option is D.
Humans belong to domains eukaryota. The domain includes four of the six kingdoms in life: Protista, Fungi, Plantae and Animalia. The other two domains are Archaea and Bacteria.
Answer:
B. The products of photosynthesis are the reactants of cellular respiration.
It is more of a web because it can start in any order and move into any rock type. example being you can start as a sedimentary rock and turn into a metamorphic rock or igneous rock. a cycle starts anywhere and then goes into a specific cycle.

This is a rather subjective question and has a lot to do with the type of society in which one lives. the more secular the world is becoming... gives science a huge spotlight on the stage. because science provides an answer with tons of evidence to back it up, it is seen as a reliable method to follow. So, socially speaking you may have experienced in a normal conversation where someone turns around and tells you that your opinions are just opinions and have nothing factual to back them up. This is where science comes in. Economically and politically speaking, science is used to justify different political aims of governments. However, this is done mostly through the misrepresentation of science by people who are trying to pursue their own agenda. So really this question can be answered in many ways and from many different perspectives but do not forget that science influences all streams for the better but also for the worse in the way in which it is represented.
Hope that helped
