Answer:
From this it can be deduced that the fresh water is hypotonic and the salt solution is hypertonic to the cells of the celery stalks.
Explanation:
When submerged in water, the celery stalks become stiff and hard, this shows that water moves within the stalk, thus, water is hypotonic in comparison to the celery stalk. Therefore, water moves from the region of higher concentration to the region of lower concentration.
When the same celery stalk is administered into the 0.15 M solution it turns soft, which shows that water from the celery stalk moves out. Thus, the salt solution is hypertonic in comparison to the celery stalk. Therefore, freshwater is hypertonic and the solution of salt is hypertonic to the celery stalk cells.
Of the total amount of glucose energy consumed by the body each day, about 20% is used by the brain and nerve cells.
The brain constitutes about 2% of the total body but it is one of the main consumers of energy derived from glucose.
The energy provided by glucose is used for the proper functioning of the brain. It generates ATP which is an energy source that is responsible for r neuronal and non-neuronal cellular maintenance and generates neurotransmitters.
Thus glucose-derived energy is critical for the health of the brain. Lack of energy can cause several brain diseases.

Answer:
single "golden poison frog" harbours enough poison to kill 10 grown men, making these frogs perhaps the most poisonous animals alive. They are one of many species of toxic frogs, which are known as poison dart frogs. They are all small: the largest are no more than 6cm long, and some are just 1.5 cm. How did these tiny, beautiful creatures become so poisonous,

Answer: The correct answer would be lactic acid fermentation.
Explanation:
In humans, specially in muscle cells, lactic acid fermentation takes place during high intensity exercise. During exercise when oxygen supply fails to meet the demands of muscle, they undergo lactic acid fermentation instead of cellular respiration.
During this process, the pyruvate (end product of glycolysis) is converted into the lactate with the help of enzyme lactate dehydrogenase.
It regenerates NAD⁺ lost in the glycolysis and thus, helps in continuous working of glycolysis.
You would be crossing Pp and Pp. If you put them in a punnet square, the four possible gene combination you get would be PP, Pp, Pp, and pp. In all cases except the last, the resulting flower's phenotype would be purple. So the probably of purple flowered offspring is 75%, or 3/4.
