Answer:
Two, usually
Explanation:
A diploid plant has two copies (alleles) of every gene. If one copy of the gene is destroyed by a mutation, the plant will likely be okay with its other copy, and the trait will still be expressed.
However, some traits require both copies of the gene to be expressed. For example, if one gene is destroyed that means only half the amount of the gene product is produced. If that is not enough protein for the trait to be expressed, then the trait will be lost.
Answer:
B and A respectively. Cones for gymnosperms and flowers for angiosperms
chaos theory was developed to analyse many nature’s complex phenomena that seem to defy prediction. In chaotic systems, small perturbations can have large and seemingly unpredictable effects. There is the famous example of a butterfly’s flapping wings influencing the weather thousands of miles away.
it can be applied to ecosystems. Empirical dynamic modeling, which is based on chaos theory, uses sea surface temperature to help predict salmon population fluctuations.
In the 50s the model of the atom looked like a planet, with the electrons circling the nucleus. Now we know the elections are shared by many nucleuses so that the model was actually very misleading.
