Celular respiration break down carbon-based sources of energy and harness the energy is chemical bonds through ATPs, the energy currency of cells. Some ATP is spent in initiating the biochemical reactions, however, there is a net positive gain in the produced ATPs at the end of the reactions. 
 
        
             
        
        
        
Answer:
False
Explanation:
Approximately 200 out of 200 million sperms ejaculated during intercourse reach the general vicinity of the egg.  They sperms must undergo capacitation during which dilute inhibitory factors fluids of the female reproductive tract weaken the membrane of the sperm head so that head of the sperm can be broken easily when it came in contact with the egg. 
The first sperm to reach an egg isn’t the one to fertilize it because the egg is surrounded by a gelatinous membrane called the zona pellucida. Outside this layer, a layer of small granulosa cells also present. 
Therefore, it requires numerous sperm to clear a path through these barriers before one of them can penetrate the egg and fertilize it. 
 
        
             
        
        
        
Denitrifying bacteria convert nitrate into <u>nitrogen gas</u>, thus returning nitrogen to the <u>atmosphere</u>. 
Denitrifying bacteria- Numerous phyla are included in the broad class of bacteria known as denitrifying bacteria. This group of bacteria, which is a part of the nitrogen cycle, may carry out denitrification together with denitrifying fungi and archaea.
Phylum (Phyla)- In biology, a phylum is a rank or level of taxonomic categorization that comes after a kingdom but before a class. Although the nomenclature for algae, fungus, and plants is recognized by the International Code of Nomenclature as being equivalent, division rather than phylum has traditionally been used in botany.

In practice it is enough to simply angle the thermometer towards the direction of the ear canal. More specifically you are trying to target the direction of the tympanic membrane located in the middle ear (one of the parts of the ear; the other parts being outer and inner)
Some maneuvers, although not completely necessary, may include pulling the ear lobe upwards and outwards for babies. This is to straighten the ear canal and is more often done when using otoscopes. For adults, we pull the ear downward and outward.
