During the warm temperatures of summer, the arctic fox produces enzymes that cause its fur to become reddish-brown. During the c
old temperatures of winter, these enzymes do not function. As a result, the fox has a white coat that blends into the snowy background. What explains this change in color? the genes of a fox are made of unstable DNA
mutations can be caused by temperature extremes
random alteration of DNA can occur on certain chromosomes
the expression of certain genes is affected by temperature
<span>The movement along the concentration gradients allows for the cell to maintain homeostasis. Keeping a cell in the proper conditions inside and out allows for it to function properly and carry out the duties that it is required to do as part of its bodily system.</span>
The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose. Photosynthesis is a two stage process. As is depicted here, the energy from sunlight is needed to start photosynthesis. The initial stage is called the light reactions as they occur only in the presence of light
