Answer:
A change in pH will cause many cellular processes to be disrupted because they affect the biomolecules (protein and nucleic acid) responsible for these processes.
Explanation:
pH refers to the degree of acidity or alkalinity. In a cell, the structures and processes that occur in them are impossible without the biomolecules, which are carbohydrate, protein, lipids and protein.
However, unfavorable conditions like a change in pH can cause the structure of some of these biomolecules to be affected. Proteins are made up of amino acids, which gives them their shape that is peculiar to their functioning. Also, nucleic acids such as DNA are composed of nucleotides responsible for their functioning.
A change in pH will cause the bonds of the protein to be disrupted, hence altering its shape and ultimately its functioning. Likewise, the hydrogen bonds in the DNA will be broken in the presence of a high pH causing the DNA to be dysfunctional.
When these biomolecules are affected, the vital functions that they perform in a cell, which is key to the cell's survival are disrupted) are likewise affected. Therefore, the cell is affected negatively.
Answer:
1.The light-dependent reactions;
The light-independent reactions, or Calvin Cycle
2.Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
3.In production, a final product, or finished product is a product that is ready for sale. For example, oil is the final product of an oil company. The farmer sells his vegetables as his final product, after they have been through the whole process of growth.

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:
Describe how oxygen gas is produced during photosynthesis?
Photosynthesis entails the reaction between carbondioxide and water which gives glucose and evolve oxygen
