The two diagrams below represent a sugar molecule and a fat molecule 1 point that is used by living organisms. Which statement best describes these two molecules?
The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.
Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.
During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.
When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.

Alyssa's additional observation would be cell Y having a larger vacuole than cell X. The third option is the correct one.
<h3>Plant cell vs animal cell</h3>
From the observations, both cells are eukaryotic. This is because:
- cell X has lysosomes which are only found in eukaryotic cells
- cell Y has a nucleus which also peculiar to eukaryotic cells only
Lysosome houses digestive enzymes and is found mostly in animal cells. Only a few plant cells have lysosomes.
Thus, the lack of a lysosome means that cell Y is a plant cell while the presence means that cell X is an animal cell.
Generally, plant cells have larger vacuoles than animal cells.

Answer:
c) allowing an organism to adjust to changes in environmental conditions
Explanation:
A stimulus can be defined as any change in the external or internal environment that produces a corresponding response in the organism. These responses enable the organism to maintain an internal equilibrium (homeostasis). Gene expression in prokaryotes, which are the simplest forms of life, is highly regulated by environmental stimuli. Some examples of stimuli known to regulate gene expression patterns in prokaryotic organisms are light, water, pressure, temperature, etc.
Answer: Respiration is a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
Hence, respiration helps to maintain a persons health.
