All cells in your body have but specialize due to .
In an experiment, scientists expose developing frog embryos to different temperatures. They find that embryos kept at a cooler temperature develop into males, while those at a warmer temperature develop into females.
How does temperature impact the developing frog embryos?
In an experiment, a group of developing cells is exposed to different concentrations of a hormone. The cells exposed to a higher concentration start to form liver tissue, while those exposed to a lower concentration become skin cells.
Which of these best explains how hormones contribute to cell differentiation?
When a stem cell divides, it produces two daughter cells. One daughter cell will remain a stem cell, while the other daughter cell will differentiate into a specialized cell.
Which factor will most likely determine what type of specialized cell will be produced?
In humans, cell specialization involves various hormone signaling as all cells originate from the single zygote formed when an egg and sperm cell join. Similarily, plants emerge from one cell in the form of a seed. In plants, the hormone auxin is involved in the development of specialized cells including root fibers, stems, leaves, and flowers.
Based on the description given, which statement below is true?
A group of plant seedlings is exposed to different amounts of light. The seedlings under sufficient light develop chloroplasts and begin photosynthesis, while those kept in darkness remain pale and fail to develop chloroplasts.
What does this observation suggest about the role of light in cell specialization?
The diagram below shows different types of specialized cells in the human body.
Explain where these cells originated (came) from, AND how they specialize to perform different functions, even though they have the same DNA.

Which processes created the genetic diversity seen in the brothers?
Which of the following best explains why siblings do not look the same, even though they share the same parents?
What is one benefit of independent assortment in sexually reproducing organisms?
Which statement best explains why gametes must go through chromosome reduction to be haploid instead of diploid?
At the end of MEIOSIS, the cells contain of the genetic information because .
The daughter cells at the end of meiosis are because of the processes of . This process is important because it results in .
Which processes during Meiosis lead to genetic diversity in the gametes produced?
