Answer:
An increase in membrane thickness
Explanation:
Gaseous exchange occurs in relation to Fick's Law which states:
'the rate of diffusion is proportional to both the surface area and concentration difference and is inversely proportional to the thickness of the membrane
Therefore, based on this law, an increase in the thickness of the membrane will result in a decreased diffusion rate which will in turn slow down the process of gaseous exchange
Answer:
Thymine
Explanation:
DNA nucleotide bases always attach in specific pairs.
Adenine is always with Thymine and Cytosine is always with Guanine. Here, since one nucleotide is Adenine, we know the other nucleotide is Thymine.
One way to remember this pairing is by this device:
Car in the Garage (cytosine goes with guanine)
and
Apple on the Tree (adenine goes with thymine)

Answer:
Competition for food happens when there is a limited amount of food resources available. The members of a species that eat that food who are best adapted to access the food are more likely to reproduce and pass on their genes to the next generation.
For example, we have a bird feeder with a narrow opening for food. The small-headed birds can reach the food, the bigger-headed birds cannot. If this was the only food source for this area, then over time, there would be more smaller-headed birds than large-headed birds, due to the competition for food and success/lack of success.
