Answer:
Bubbles are a sign that the yeast is alive, and that it is performing anaerobic respiration. You should notice that the mixtures with too little and too much sugar do not grow, bubble or foam properly. This is because the yeast needs the perfect amount in order to produce carbon dioxide.
Explanation:
Answer:
The correct answer is B. pyruvate
Explanation:
In glycolysis, glucose is oxidized to produce 2 molecules of NADH, ATP, and pyruvate. Then this pyruvate molecule is used in the Kreb cycle and gets fully oxidized into carbon dioxide and water.
This oxidation of pyruvate molecule gives rise to more NADH and FADH₂ molecule. These molecules are reduced form of energy which is used as a source of electron during oxidative phosphorylation to produce more ATP molecules.
Therefore pyruvate is the useful product of glycolysis which is utilized to give energy to the cell in the form of ATP.
Answer:
germination will halt
Explanation:
Germination will be stopped because radicle helps in absorbing of nutrients from the soil that leads to germination of the seedlings. Radicle are the first roots that emerge from the seed that is responsible for the absorption of nutrients from the soil in order to increase the growth of seedlings in size. If this radicle get damaged, the growth of the plumule is stopped due to no absorption of nutrients from the soil that is necessary for the growth and development of the plant.
Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.

After plants absorb energy from the Sun, the energy gets converted into chemical energy for the plant to carry out life activities. Chemical energy is used up by the different processes within the plant cells (e.g. cellular respiration, photosynthesis).
Please correct me if I'm wrong.. :)
