Question:
Trudy made this Venn diagram comparing interphase and cytokinesis.
Which statement belongs in the region marked X? (image attached)
Answer options:
- Is the longest stage
- DNA is copied
- The number of nuclei doubles
- The number of cells doubles
Answer:
- The number of cells doubles
Explanation:
Cytokinesis describes the splitting of the cytoplasm after mitosis. During interphase, the DNA is replicated. During mitosis, the DNA condenses into chromosomes, and the chromosomes are aligned and separated to opposite ends of the cell. During cytokinesis, the cell separates into two daughter cells.

Answer:
H. pylori uses the enzyme urease to breakdown urea into ammonia (NH3) & carbon dioxide (CO2), where NH3 can act as a buffer to the acidic solution in the stomach.
Explanation:
<em>H. pylori</em> is a bacteria that has the enzyme urease to breakdown urea into ammonia (NH3) & carbon dioxide (CO2). The compound of interest here would be ammonia, or NH3. NH3 is a base, although relatively weak to other stronger bases, which means it has a pH above 7. In the stomach, the pH is acidic, or below 7. By synthesizing ammonia, <em>H. pylori </em>is able to buffer the stomach solution in a manner so that it isn't entirely acidic, but more toward the basic side, thereby allowing for its survival.
Answer:
The correct answer is A. scavengers and B. producers
Explanation:
Two types of factors are found in a biome biotic and abiotic factor. All the living things in any biome comes under biotic factors like animals, plants, and microbes and all the non-living things present in the biome are non-biotic factors for example soil, temperature, air, water, salt, etc.
So biome is made up of both living and non-living factors. Scavengers are the organisms that feed on dead and decaying matter and producers are the organisms that make their own food. Most of the producers are plants.
So both scavengers and producers are living organisms therefore both are examples of biotic factors.
