Compare the environmental and societal impact of urban sprawl to upward growth
Answer:
Urban sprawl can also be called Urbanization and it means the movement of a population from the densely populated cities to the low populated areas around the cities which isn't usually well developed.
Urbanisation has a great impact on the environment because it leads to cutting down of trees which is also known as deforestation.
Deforestation is very harmful for the environment because it creates a form
of dis balance in the environment. Trees are very important to us humans because they provide us with raw materials and oxygen. This means we should always be mindful of deforestation processes.

Shorter strands of DNA travel more easily and over time, farther on the agarose gel than larger strands
Answer:
true
Explanation:
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode. Shorter strands of DNA move more quickly through the gel than longer strands resulting in the fragments being arranged in order of size

How can you make it safer to exercise on a hot day?
A. Do not exercise between 11 a.m. and 5 p.m., the hottest hours of
the day.
B. Wear loose-fitting clothes that allow sweat to evaporate.
C. Drink water before, during, and after a workout. Drink water at
least every 20 minutes while exercising.
D. All of the above.
We can make it safer to exercise on a hot day by Option(D) All of the above.
What happens to our body if we exercise on a hot day ?Exercising in hot weather puts extra stress and pressure on our body. If we don't take care when exercising in the heat, we risk serious illness. Both the exercise itself and the air temperature and humidity can increase your core body temperature. To help cool itself, your body sends more blood to circulate through your skin. If the core body temperature is high for a prolonged time, the person may loose consciousness and even suffer from cardiac arrest.
How to make it safer to exercise on a hot day ?First of all, we should not exercise between 11 a.m. and 5 p.m. as it as the hottest hours of the day and the person may have heat stroke. Even if we exercise, after avoiding the timing of the day, we should wear loose-fitting clothes that allow sweat to evaporate. Finally, the most important point is to drink water before, during, and after a workout. Drink water at least every 20 minutes while exercising.
Thus Option(D) All of the above satisfies our exercise on a hot day.

We interviewed 3 students about what they thought were the reasons for the change in Guppy population and this is what they said:
● Norise says the change in the guppy population was caused by a mutation.
● Lauren says the change was caused by a change in the environment.
● Megan thinks both Norise and Lauren are correct.
Who do you think is right? Explain what happened to the guppies over many generations.
Use multiple pieces of evidence of the notes in your answer to receive full credit.
Answer:
Answer:
Megan is right.
Explanation:
The guppy is a very adaptable freshwater fish, commonly found in aquariums world wide. The success of the guppy is mostly due to its ability to adapt to the changes in its environment. Guppies were originally found in the southern american continents and the Caribbean island, but has been exported all over the world, first as a means of curbing the spread of mosquitoes by feeding on the larvae and then as a pet. Over time, guppies have found themselves in diverse environment, and some have undergone mutation of body parts just to adapt. So, the need for adaptation to their constantly changing environment has led to mutation in the guppies.

Some organisms seem to have undergone very little evolutionary change
over huge spans of geologic time. One example is the shark. Shark
ancestry dates back around 425 million years, which is about 200 million
years before the earliest known dinosaur. In all, abut 2000 to 3000
species of fossil sharks have been documented. About 1100 species of
shark remain on Earth today. These sharks represent an ancient life form.
Why do you think the rate of evolution of the shark has been so gradual?

Are the finches that Charles Darwin studied on the Galápagos Islands an example of divergent evolution or convergent evolution? Give two point to explain your thinking.
Answer:
shark are slow evolving species because of lower gene flow and rate if reproduction.
Darwin finches undergo divergent evolution
Explanation:
Sharks have evolved slowly because of following reasons –
a) Lower rate of reproduction
b) Restricted gene flow because of isolated habitat such as stretches of deep water
c) Staying close to the eggs and hence guarding them throughout their life thereby allowing no cross mating.
d) Lower rate of mitochondrial DNA (mtDNA) evolution
Darwin’s finches show divergent evolution as different species of finches originated from a common ancestors. The beak size of finches vary form one species to other because of different diet habits
