Chapter 10 & 11 Test Review

Front

What is codominance?

Back

Codominance is a genetic scenario where two different alleles are expressed equally in the phenotype of an organism, resulting in both traits being visible at the same time.

Front

What is the main difference between embryonic stem cells and adult stem cells?

Back

Embryonic stem cells can differentiate into more cell types than adult stem cells.

Front

True or False: The larger a cell is, the more difficult it is for the cell to move enough nutrients and wastes across its cell membrane to maintain its normal functions.

Back

True

Front

During which phase do chromosomes condense into rod-like structures?

Back

Prophase.

Front

What determines the amount of nutrients a cell needs?

Back

The cell's volume.

Front

Define stem cells.

Back

Stem cells are undifferentiated cells that have the potential to develop into various cell types in the body.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What is the significance of surface area to volume ratio in cells?

Back

A higher surface area to volume ratio allows for more efficient nutrient uptake and waste removal.

Front

What are linked genes?

Back

Linked genes are genes that are located close to each other on the same chromosome and tend to be inherited together.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation where one allele does not completely dominate another, resulting in a blended phenotype.
