Stem cells are differentiated into different types of cells by a process called signaling, which leads to changes in gene activity, causing the cell to differentiate.
Answer:
Number of chromosomes
Explanation:
Meiosis is a specialized type of cell division in which the gametes are produced.
A diploid parent cell first replicates its DNA. Then, two rounds of cell division occurs to produce 4 haploid cells, each with half the amount of chromosomes. These gametes fuse during fertilization to restore the diploid state.
Therefore, meiosis changes the number of chromosomes.
Scientists classify organisms to make them easier to study. Taxonomy is very useful to scientists because once an organism is classified they can already learn about it
The Calvin Cycle
Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.
