That is true and cacti with many spines are typically preferred by parasites. This is an example of bidirectional selection in which evolutionary pressures from multiple sources encourage an organism to adapt.
Answer and Explanation:
- What was Patrick’s hypothesis? <em>Fishes that are fed with food exposed to the microwave will become smarter and will swim faster. </em>
- Which fish are in the control group? The ones that feed on regular food
- What is the independent variable? Food exposed to the microwave
- What is the dependent variable? The time fishes spend in swimming through the maze
- What should Patrick’s conclusion be? You will find the results considered in the attached file.
<em>In both groups, Patrick recorded a decrease in the time spent swimming through the maze</em>. In both groups, there were two cases in which the animal increase the swimming time. These cases could be considered as outliers. Although in general, <em>the treated group made it in a shorter time after the treatment, when comparing values before and after Patrick can not find any real difference among groups.</em> <em>His results do not show any difference,</em> hence <em>the speed and the intelligence of the animals is not influenced by the change in food, or if it is, more experimental time is required to record significant differences. </em>
Answer:
I believe your answer is d
This is an example of co-evolution.
<u>Explanation:</u>
In co-evolution one species or a number of species evolve according to the changes in another species. Here the evolution of the beak of humming bird according to the shape of Ossifloramixta flower is an example of co-evolution. Co-evolution is common in the nature.
Bees, insects and butterflies commonly co evolve with the flower plants and vice versa. Co-evolution is of two types. The first type is specific co – evolution where only two parties are involved in co-evolution. In the second type of co-evolution namely diffused co-evolution many species evolve in response to specific traits in a species.
