The AQP1 gene in humans codes for the AQP1 protein (aquaporin-1), which allows water to pass through plasma membranes via osmosis. If there were a mutation to this gene that prevented the proper function of AQP1, which
option below best predicts the most likely outcome?
a. Cells would be unable to uptake water due to the non-functional AQP1 protein.
b. The mutation to the gene would cause a change in the amino acid sequence of the protein, which would
ultimately affect the protein’s 3D structure and function. This would allow for more water to be taken up by
cells.
c. Cells would still be able to uptake water, as water can pass through the cell membrane without the assistance
of aquaporins. However, it would take up water at a much slower rate because water has a slight charge.
d. A change in shape and function of the protein would prevent ATP from transferring its terminal phosphate
group to the aquaporin, thus preventing water from passing through the channel.

Tara sees a commercial for a brand of pills that promise to boost energy and people perform better in work and school. as people in the commercial talk about how much better they feel when taking the pill, tara notices a message on the bottom of the screen that reads, "this pill is not approved by doctors and has not been tested in controlled experiments." what is the best conclusion that tara should make about the commercial? it is making scientific claims based on subjective observations. it is making scientific claims based on opinions instead of pseudoscientific facts. it is making pseudoscientific claims based on objective observations. it is making pseudoscientific claims based on opinions instead of scientific facts.

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding? it will be important to include cysteine in the diet of the mice. cysteine residues are required for the formation of α helices and β pleated sheets. cysteine residues are involved in disulfide bridges that form tertiary structure. cysteine causes bends, or angles, to occur in the tertiary structure of proteins.

Parthenogenesis is a type of reproduction that does not require a mate. it’s rarely seen in birds and higher vertebrates. parthenogenesis involves the formation of a zygote. but this zygote is formed without fertilization. in parthenogenesis, in the absence of a male gamete, the ovum develops directly in the zygote.
