Read the following scenario to answer this question:[/HTML]Mike loves to cook. He heard that if you add salt to water, it will boil faster. If it’s true, it could save him a lot of time in the kitchen. He decided to perform an experiment to test this hypothesis. He set up three pots, each containing three liters of water. In the first pot, he didn’t add any salt; in the second pot, he added one tablespoon of salt; and in the third pot, he added two tablespoons of salt. He got out his stop watch and turned the stove on under all three of the pots.Is there a control group, and if so, what is it? ____________________

11. Many plants use brightly colored flowers to attract insect pollinators.
Which is the MOST likely conclusion about a plant that has very small flowers that
are hard to see?
CLE
Answer: Pollen can be blown in the wind which the bees/other pollinators can follow to get to the flowers.
Explanation: Plants rely on bees and other insects to reproduce and so they have adapted, over time, to become more attractive to them. Bees are drawn to plants with open or flat tubular flowers with lots of pollen and nectar. A flower's scent can have particular appeal to bees, and its bright colors or pollen being blown in the wind may lure the bees in.

The table below shows the percentages of bases in a DNA sample. How much Guanine (G) should you expect to find in the sample?
Answer:
17%
Explanation:
guanine is cooped
with cytosine
Using Chargaff's rule, the percentage of Guanine(G) in the sample is always equal to the percentage of Cytosine. Hence, the percentage of Guanine which is expected to be found in the sample ls 17%.
From the table attached :
Thymine = 33%Cytosine = 17%According to Chargaff ; the percentage of Cytosine equals the percentage of Guanine :
Guanine = Cytosine = 17%.
Percentage of Thymine equals the percentage of Adenine :
Adenine = Thymine = 33%Therefore, the amount of Guanine which is expected to be found in the sample is 17%

1. The peppered moth is found in England during the industrial revolution. Coal was used as the top fuel during this. The problem with coal is that it is very dirty
and produces soot. This soot begins to cover the trees. Eventually the trees become darker, see the picture on the right. Use the data below to explain what
happened
Answer:
This is an example of natural selection. There were two types of moth colors, white and black and white. Before the industrial revolution, the environment had white trees, meaning that the white moths can blend in. The black moths are more likely to be eaten because they stick out. Now that the trees are black, the white moths stick out more causing there to be more black moths.
Explanation:
I do not see any data but this is a general explanation.

1. What is the function of a top predator in an ecosystem?
A. It increases the food for other predator species.
B. It creates imbalance in the ecosystem.
C. It maintains populations. **
D. It helps increase the number of prey.
Reason - The answer is C because predators couldn't possibly increase the food for other predators. They obviously don't imbalance the ecosystem since they help keep it cycling. And they can't increase the number of prey if they're eating prey so therfore you're left with C.
2. Which is considered a top predator in the ocean?
A. A shark**
B. A sea lion
C. A small whale
D. A bird.
Reason - The answer is A because actually the top predator in the ocean is the killer whale but since it's not an option, you'd wanna go for a shark. A small whale obviously couldn't eat a big shark, nor could any of the others. :)
3. What happens to an ecosystem during normal seasonal flooding?
A. The biodiversity of the area reaches equilibrium.
B. The biodiversity of the area increases. **
C. The biodiversity of the area decreases.
D. The biodiversity of the area stays the same.
Reason - Just trust, I'm trying to finish this post and got tired of giving reasons. Sorry and thanks:)
4. How is the impact of seasonal flooding different from damming a river?
A. Seasonal flooding helps balance biodiversity, but damming does not.
B. Seasonal flooding is not considered an ecological disturbance like damming.
C. Seasonal flooding does not impact biodiversity for as long term as damming.**
D. Seasonal flooding increases biodiversity, but damming does not.
Reason - Again, trying to finish this and tired of typing reasons but the answer is indeed C because damming a river can causes long-term damage to biodiversity and the ecosystem while it can quickly recover from a flood because it doesn't really damage as much and the flood will simply be gone after a bit. :)
5. Would a long-term increase in the average temperature of a region be considered a significant disturbance in the ecosystem?
A. No, because it would not create large-scale changes in the environment.
B. No, because increases and decreases in average temperatures are normal.
C. Yes, because such a change could have a large-scale impact on wildlife. **
D. Yes, because any slight change in temperature is considered a distribution.
Reason - Eh.. it's pretty self explanatory.
It maintains the population. The top predator of the ocean is a shark, biodiversity of the area increases, the seasonal flooding may impact biodiversity for as long term as damming. Yes, due to the change could have a large-scale impact on wildlife.
What are the Exkplanion for the above answers?As per the top predators of the ecosystem, thy duty is to maintain the level of populating in the community. As they hunt down prey and thus be balanced. The ocean is just like the land is full of predators and prey the shark is the largest top predators species in the oceans.
A dammed river can create long-term damage to the biodiversity of the region. As flooding can lead to disaster and may impact the food supply. A long-term increase in the temperature of the region can lead to a large impact on wildlife.
