Which of the following statements about the effects of climate change on phenology is true?
a. climate induced changes in phenology have been documented in many different taxa
b. as climate warms, temperature-cued spring events are occurring later in the year.

d. changes in timing are more likely when events are cued by day length, not temperature

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.
