The correct answer is: a. using a photographic negative to make a positive image
A negative image is a total inversion of positive image (normal image). Negatives are normally used to make positive prints.
This can be compared to copying mechanism of DNA-replication of DNA in which one strand of DNA (e.g. 3’-5’ orientation) is used as a template to make new strand with opposite orientation (5’-3’).
Flagellum. This is the only thing I could come up with because you did not provide an image.
3. The sperm is produced inside the scrotum and stored in the e<span>pididymis. During ejaculation, the sperm flows through the Vas deferens and the ejaculatory duct before reaching the urethra. The urethra is the tube inside the penis that ends in the preputial orifice or the hole at the tip of the penis where the sperm flows out.</span>
4. Meisos produced egss
The major food molecule in living organisms is a sugar called glucose. Most carbohydrates (sugars and starches) are converted into glucose before they are broken down in the cytosol to release energy. The series of steps where glucose is broken down to release energy begins with a metabolic pathway called glycolysis. Glycolysis is the "lysing" or cutting of glucose to release energy. The six carbon sugar, glucose, is cut in half and converted into two three carbon sugars called pyruvate. What happens next depends on the presence or absence of oxygen.
If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. This process is called aerobic respiration because it requires air (oxygen). In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation. Fermentation doesn't break the sugar down any further, it simply helps reset the system so that more sugar can be broken down.
Because aerobic respiration breaks the sugar all the way down, it releases much more energy than fermentation.
I’m pretty sure it’s D) Fermentation since it isn’t related to fossilization
