Some events that take place during the synthesis of a specific protein are listed.
A. Individual amino acids connect to form an amino acid chain
B. mRNA leaves the nucleus
C. mRNA attaches to a ribosome
D. DNA is transcribed into messenger RNA

Internal factors question
Testosterone is a hormone found in both males and females. Testosterone levels change over time. During puberty, certain hormones testosterone trigger changes in the body. For example, many boys experience voice cracking as their voice deepens or start to produce more body odor as they sweat.
What factor best explains the variation in testosterone levels in males and females?
The Himalayan rabbit’s habitat has cold, snowy winters and mild summers. The body is typically covered in white fur except for the nose, feet, tail, and ears, which are covered in black fur.
A scientist shaved an area of white fur on the back of a Himalayan rabbit and placed an ice pack over the shaved area. The shaved area grew black fur.
Which of these best explains why the hair that grew back where the ice pack was placed was black and not white?
How do external and internal factors affect the traits that an organism exhibits?
Look back and Himalayan rabbit item that connects to gene expression and production of proteins.
Insulin is a hormone that is produced in the pancreas. Insulin functions as a key to allow glucose (sugar) from the bloodstream to enter the cells. Glucose provides the body with the energy needed to function properly. Without insulin, glucose in the blood stream will build up in the blood leading to high blood sugar levels. People with diabetes do not produce their own insulin.
What factor is most responsible for the lack of insulin in people with diabetes?
Internal factors
Gene expression determines what a particular cell can do

An illustration of a mutation is shown below.
What type of mutation is illustrated?
Mutations in somatic cells are not heritable, but mutations in gametes are heritable
**Make multiple choice.
A strand of mRNA reads:
Which of the following mutations would cause the biggest change in the protein produced?
Which of the following would lead to a mutation of an individual's genetic code?
Select TWO that apply.
Mutations can be caused by errors in DNA replication, chemicals or radiation
The following mutation has occurred in Claire's MC1R, the gene responsible for producing hair color.
The mutation that has occurred is a . As a result of this mutation, the protein produced .

What role do the enzymes DNA helicase and DNA polymerase play in DNA replication?
Observe the mutations in the diagram below.
Which statement is best supported by the diagram?
Liver cells and neurons are two cells found in the human body with highly specialized functions.
Which is the best explanation for why these cells perform different functions if their nucleus contains the same DNA?
One application of CRISPR-Cas9 is to modify the DNA sequence of mosquitoes so that they can no longer spread diseases such as malaria to humans.
How does CRISPR-Cas9 influence gene expression?
Amphibians such as frogs undergo various developmental and structural changes throughout their life cycle. Many frogs start in the water, but eventually grow legs to walk on the earth.
What drives these developmental changes during the frog's life cycle?
When certain plants are eaten by caterpillars, they begin to produce capsaicin, a compound known to make fruits spicy. This mechanism most often seen in peppers is how plants defend themselves against predators.
What explains why some peppers are spicier than others?
