Answer:
The correct answer is d. high sugar concentrations stimulate cellular respiration, and alcohol is not a by-product of cellular respiration.
Explanation:
As they added sweet grape juice mixture the amount of sugar increased in the content and it is seen that more than 6 % of sugar decreases the rate of fermentation and alcohol concentration also decreases and a moderate amount of glucose concentration in the anaerobic environment increases the fermentation results in more alcohol production.
High sugar concentration decreases fermentation but increases cellular respiration in the yeast, as a result, it uses more sugar for its growth and produce CO₂ and H₂O so alcohol is not the by-product of cellular respiration. Therefore the correct answer is d. high sugar concentrations stimulate cellular respiration, and alcohol is not a by-product of cellular respiration.
I am decent at it somewhat lol
Answer:
SRY
Explanation:
Sex determination in mammals including humans is genetically and hormonally controlled.
Genetically gonadal sex determination is mediated by a gene called SRY. This gene is known as the mammalian Y-chromosomal testis-determining gene. It induces sex determination in males.
Recent studies revealed that SRY plays an important role in inducing Sertoli cells differentiation. The Sertoli cells, in turn, guide testis formation.
Therefore, in males, differentiation of testis is switched on by expression of the Y-linked SRY gene.
Dale’s motor neurons carry instructions from his central nervous system to his muscles.
Motor neurons are special brain nerve cells that transmit impulses from the brain or spinal cord to a muscle or gland. The motor neurons functions with a network of other neurons, situated within the spinal cord and the brain. The two main subtypes of the motor neurons are; the upper motor neurons (which comes from the brain and connects with the lower motor neurons), and the lower motor neurons (which localize in the brainstem and the spinal cord).
