Answer:
200 ATP molecules
Explanation:
Yeast is a fungus that undergoes fermentation instead of cellular respiration when there is an absence of oxygen. In the fermentation process undergone by yeast, which produces an alcohol as product (alcohol fermentation), two (2) ATP molecules are produced as net ATP.
However, if a yeast cell undergoes fermentation and uses 100 molecules of glucose, the yeast cell will generate a net ATP of 2 × 100 molecules = 200 molecules.
Answer:
B. Sexual reproduction
Explanation:
Reproduction in living organisms, which is the process of creating new copies of a particular species, can occur asexually or sexually. The asexual method of reproduction involves only one organism however, the sexual reproduction involved two organisms of different sexes (male and female).
In sexual reproduction, the male organism produces male gametes (sperm) while the female organism produces female gamete (egg). These two sex cells or gametes come together in a process called FERTILIZATION to form one new cell called ZYGOTE, which eventually develops into a new organism.
Answer:
The correct answer is - Mutation in particular DNA segments can lead to the loss of apoptotic control which allows the cancerous or damaged cells to survive longer.
Explanation:
An error or change in a DNA segment or DNA repair gene mistakes become mutations if not corrected. These mutations may lead to change in the function of the specific functions that may lead to cancer. Such mutations are tumor suppressor genes or oncogenes. The activities of genes regulate the signal when they detect damaged cells and such cells should undergo apoptosis (programmed cell death).
The loss of apoptotic control by a mutation in such genes allows cancer cells to not follow apoptosis and leads to survival for a longer time and allow them to divide, accumulate and proliferate.
1) pathogen
2) viruses
Some bacteria are not harmful to your body hence not all of them are pathogens
