Cell division that makes sperm and egg.
Meiosis
Reaction that transfers light energy into chemical energy.
A scientist observes a cell with a damaged cell membrane. The cell can no longer effectively regulate what enters and leaves. This function is known as:
Homeostasis
Amino acids
The preserved remains or traces of ancient organisms are known as:
Fossils
The structure in the uterine lining responsible for giving the nutrients to the baby.
Placenta
Factors such as food, water, and space that restrict population growth.
Limiting factors
In Type 1 diabetes, the body's immune system destroys cells in the pancreas that produce this hormone.
Insulin
A segment of DNA that contains the instructions for making a specific protein is called a:
Gene
Embryos of different vertebrates show similar early development patterns. This is evidence of:
Common ancestry
What process is being described?
A cell in a developing fetus can divide into muscle and bone cells with the same DNA, but the cells have different shapes and functions.
cell specialization
This process breaks down dead plants, animals, and waste materials, returning nutrients to the geosphere
Decomposition
If the kidneys fail to remove excess water effectively, this body system is most directly affected because blood volume changes.
Circulatory
A mutation changes a DNA codon, but the resulting protein remains unchanged. This occurred because:
The codon codes for the same amino acid
The idea that organisms with favorable traits are more likely to survive and reproduce is known as:
Natural Selection
The two names for the 2 major steps of protein synthesis.
Correctly identify the 4 spheres and provide an accurate description of each one.
Hydrosphere - water
Atmosphere - air
Biosphere - life on Earth
Geosphere - ground
This gland produces insulin and glucagon to help regulate blood sugar levels.
Pancreas
Researchers compare a nerve cell and a skin cell from the same individual. They discover that both cells contain the same genes. The major difference between the cells is:
Gene expression
Anatomical and DNA/molecular
List 3 reasons why offspring from the same parents have different traits.
A pesticide accumulates in the tissues of organisms and becomes more concentrated at each trophic level. What is the name for the term that describes the increase in toxin concentration?
Biomagnification or bioaccumulation
The hypothalamus detects a rise in body temperature and signals sweat glands to increase perspiration. The sweating reduces body temperature and decreases signaling from the hypothalamus. This illustrates:
Negative Feedback
Mitosis vs. meiosis with number of cells, genetic information and purposes
A trait that increases an organism’s ability to survive in its environment is called an:
