To test your hypothesis, the same fertilizer from the farm will be mixed into the water of one aquarium (experimental) and the o

ther will be left alone (control). Each will be allowed to sit for several days in sunlight. Move the slider to see the results of the experiment. 2. Describe any significant differences you observe between the experimental and control aquariums.

Answer:

One significant difference that I noticed was the color of the water. In the control aquarium, the color of the water at 30 days was the same as it was on the 1st day. In the experimental aquarium, the water had a green tint on the 30th day, but on the first day it was clear.

Dima020 [189]

Answer:

Cooperation

Explanation:

Cooperation is a type of behavior evolved by members a species living together in a close-knit society, whereby they all work and act together to ensure the common good of all members. This behavior ensures the survival of the members of the species in any environment.  

Cooperation among small birds ensures protection of the members of the group against predators. Also, pack hunting is a form of cooperation among animals of a species to ensure nutrition is provided for all in the group. Se animals also form defensive circles as a form of cooperation to ensure protection of members, especially the weak and young members, against predators.

Which best illustrates a result of natural selection?
Yanka [14]

Answer: The correct answer is -

D) giraffes having increasingly longer necks over time.

Natural selection is an evolutionary mechanism that was proposed by Darwin.

According to this mechanism, organisms that are better capable of adapting to their changing environmental conditions, survive and increase their number through reproduction whereas other are eliminated from the population.

Example - Long neck of Giraffe, which is much elongated, lofty stature, that was beautifully adapted for browsing on the higher tree branches. This was an adaptation with slow and gradual change in the gene frequency as the lower vegetation was eaten by other animals. Due to this, giraffes had to search for other source (that was higher tree branches).

This is considered as a peculiar example of natural selection.

Seasons of Change Activity Worksheet—Disappearing Marine Iguanas Case Study
baherus [9]

Answer:

1. Using the map and the minimal knowledge that Liz has at this point, propose three different hypotheses regarding the sudden high mortality of marine iguanas. Record your answers in the worksheet and post your hypotheses to the 03.01 class discussion board before proceeding to the next question.  (3 points possible)

Hypotheses One:  Iguanas are adapted to hot/warm weather, so the weather changed could have affected them.

Hypotheses Two: There was not enough shelter for the iguanas so they started disappearing.

Hypotheses Three: A new species has come close to where the iguanas live and taken them out.

2. Look at your classmates’ hypotheses on the discussion board. Choose one hypothesis that seems most likely to you. Provide the student name and hypothesis and tell what evidence you would need to support (or refute) it. (3 points possible)   Carter Spiers, Hypothesis 1. there was a lot of rain and it washed at the iguanas away. We would have to dive into the water/ ocean and find iguana bodies to be able to prove that this is true.

3. Given what you know at this point about marine iguanas and the abiotic effects of ENSO, develop two possible directions of research that Liz should pursue to understand exactly why the iguanas suffered such a high mortality. Keep in mind that you need to consider indirect effects. While environmental temperature does change metabolic rates of ectotherms, the iguanas are exposed to a wide range of temperatures as they feed and bask on the lava. Direct mortality in response to a temperature change of a couple of degrees is unlikely.  (3 points possible)

Possible Research Direction One: The climate event caused a lot more rainfall which then made it very hard for the iguanas to reach their food source.

Possible Research Direction Two: The temperatures raised very high causing the iguanas to absorb a extreme about of extra heat, which eventually made them very lazy and stopped defending their self from predators.  

4. Choose one of those directions of research and determine what data you would need to find to support your ideas.  (2 points possible)          Specific data of the extreme amounts of rainfall.
