Statement is false.
Carbohydrates are never found in plasma membrane is not true. The biochemical investigation done on cell membrane clearly demonstrate that the cell membrane possess protein and carbohydrates as biochemical components.
The other options stand true for plasma membrane 
Plasma membrane is present in both plant and animal cells. Lipid is present as a bilayer and lipid component is made of phosphoglycerides (fluid mosaic model by Singer and Nicolson).
Proteins are present integrated as well as loosely associated with the lipid bilayer. The ratio of protein and lipid varies considerably in different cell types.

[13 pts] A recent study investigated the impact of climate change on flower phenotype by measuring the change in the proportion of UV absorbing pigment in flowers in 1,200 herbarium specimens over a 50-year period. They categorized each flower species as having their anthers exposed (picture left) or having their anthers concealed (picture right). The graph shows the change in UV absorption and change in temperature: positive values indicate more absorption or warmer temperatures later in the time period; negative values indicate less absorption or cooler temperatures later in the time period.
  1. What can you conclude from the graph on the right? In your explanation, compare the slope, R2, and p-value of each line, and how they relate to the experimental findings.
  2. As the climate warms over the next century, evolutionary biologists expect changes in both populations of flowers with anthers exposed as well as changes in populations of flowers with anthers concealed. What changes do they expect and why?
  3. The scientists suspect that absorbing UV in the petals warms the flower but helps prevent UV damage to the pollen. Given this, why is the pattern shown in the graph logical? Comment for both flowers with anthers exposed and flowers with anthers concealed.
  4. Pollinators use contrast in UV coloration to find flowers. The black and white photos to the right show the decrease in UV contrast of the same species of flower with anthers exposed at the beginning of the time period (left) relative to the end of the time period (right). Given that pollinators use the contrasting black and grey to find flowers, describe the evolutionary tradeoff (i.e., the cost of increased UV absorption) for flowers with anthers exposed and why this tradeoff is not apparent in flowers with anthers concealed.
