A) store genetic information, instructions to make proteins
B) form cell membranes, long-term energy storage, insulation

When a doctor needs to give someone a medication intravenously (through a vein), they dilute that medicine in a saline solution (salty water). Why would it be a bad idea for a doctor to mix the medicine with plain water? (Hint: Osmosis is the answer, but you’ll need to explain why.)

Club foot is a rare disease due to congenital skeletal abnormalities, both genetic and nongenetic factors are thought to be responsible for club foot. A family in which club foot was inherited as an autosomal dominant trait with reduced penetrance was identified in 2008. It was found that a mutation in the PITXI gene that caused club foot in this family. Through DNA testing, they determined that 11 people in the family carried the PITXI mutation, but only 8 of these people had club foot.

Required:
What is the penetrance of the PIXTI mutation in this family?

What are the causes of inherited genetic variation

What are characteristics used to describe matter

Using established recombinant DNA technology, you insert a gene from a human liver cell into a bacterium. The bacterium then expresses a protein corresponding to the inserted DNA. To your dismay, you discover that the protein produced is useless and is found to contain many more amino acids than does the protein made by the eukaryotic cell.
Assuming there is no mutation in the human gene, explain why this happened.
a. bacteria do not use splicing to edit RNA after its transcription.
b. rRNAs in bacterial cells contain more nucleotides than in eukaryotic cells.
c. bacterial RNA contains less stop codons.
d. amino acids in bacterial cells are specified by double codes.

Based on the data, taken at three different time points, which of the following statements best describes what is observed in the image?

A) The Golgi apparatus is dynamic. The vesicles moved exclusively from the cis face to the trans face.
B) The cisternae of the Golgi apparatus did not change in structure between the cis face and the trans face.
C) The secretory proteins are packaged and tagged for transport as they moved from the trans face to the cis face.
D) The Golgi apparatus can recycle vesicles. Some vesicles moved from the trans face to the cis face for recycling.

In which situation would artificial insemination most likely be used over other forms of treatment?
A.
A woman's ovaries do not release any eggs.
B.
A man's testicles have not properly descended, lowering sperm count.
C.
There is a blockage in the fallopian tubes.
D.
The mucus that helps the sperm travel to the uterus is too thick.

What cell makes up loose connective tissue?
