<span>No crying underwater is not possible because of 2 reasons.
1) While crying there is a spasm of muscles , of that of the oesophagus (throat) and this would result in death of an individual if he/she is under water.
2) The external fluid pressure will not permit the tear gland to secrete tears there by nullifying the possibility.
Thus u cannot cry unre water..
of course except if u are wearing a goggle or u are in a submarine! :)</span><span>

Answer:
Genetic variation is caused by:
mutation
random mating between organisms
random fertilization
crossing over (or recombination) between
chromatids of homologous chromosomes during
meiosis
Answer:
Between steps 4 and 5, the mechanical energy of the turbine is converted to <u>electrical energy.</u>
Explanation:
A turbine can be described as rotating device which converts energy from fluid like water or energy from the wind into useful form of energy like electricity.
There are different types of turbines each made to generate energy from different sources.
To generate hydroelectricity, the water which is stored in a dam (potential energy) is released over a rotating turbine (mechanical energy) made of blades which converts it into electrical energy.
Answer:
B. A drug that prevents the conversion of glucose into pyruvate
Explanation:
<em>Streptococcus mutans</em> is a facultatively anaerobic bacterium, i.e., a microorganism capable of producing ATP by both aerobic (when there is oxygen), and anaerobic (i.e., when there is no oxygen available) conditions. This bacterium is observed in the human oral cavity where causes the majority of tooth decay. <em>S. mutans</em> can digest carbohydrates (e.g. glucose, fructose and lactose) in order to produce lactic acid, which contributes to tooth decay. Glycolysis is the fermentation of glucose to pyruvate in anaerobic conditions, and thereby it is expected that a drug capable of preventing the conversion of glucose into pyruvate in anaerobic conditions is effective to prevent cavities caused by <em>S. mutans</em>.
Cellular respiration
Explanation:
The release of energy in living thins is known as cellular respiration.
In the process of cellular respiration, oxygen combines with sugar and thereby releasing energy in form of ATP(Adenosine Triphosphate) and carbon dioxide. ATP is the store house energy in the cells and during respiration, this compound is synthesized.
The sugar is produced in the process of photosynthesis in plants using carbon dioxide and water in the presence of sunlight.
