Algae are small photosynthetic organisms found in aquatic ecosystems. Their cells produce a kind of oil. Scientists learned how to extract the oil to create fuel, which can be used in place of fossil fuels. Scientists think algae can produce 60 times more oil per acre than plants, like corn, that are commonly used to produce biofuel.
To produce algae oil, very large ponds were built for growing algae. However, scientists soon made two discoveries.
As the algae grew, it formed layers at the pond surface. These layers crowded and shaded one another.
Many insects and other consumers frequently entered the ponds.
Based on the two discoveries, what would likely be a problem for algae oil production?
A.
Crowding reduces access to food, so it makes algae less able to take in sugar and produce oil.
B.
Insects feed on algae, so all of the energy stored in algae oil is converted back into light energy.
C.
Consumers feed on algae, so the energy stored in algae oil is permanently lost from the environment.
D.
Shading reduces access to sunlight, so algae produce less sugar and are less able to store energy.
Answer:
C.
Consumers feed on algae, so the energy stored in algae oil is permanently lost from the environment

Answer:
B
Explanation:
only option that reduces the use of motorized vehicles
Answer:
B. Building new bike paths in the city.
Explanation:
This is the most possible way since...
If there are more bike paths, then there are more ways that they are going, which means more usage of them. If there is going to be more usage of them, then there is going to be less usage of cars in the city.So hence, your answer is B. Building new bike paths in the city.
Now, let's look WHY are the other ones NOT the right answer:
A. Widening roads throughout the city
This just won't do anything, rather, it will make drivers more want to go on the road since the roads are wider and easier to drive on.
B. Buliding new bike paths in the city
this is the right answer, for explanation, look above
C. Expanding the city into nearby areas
There is no use of the city being expanded, that way, if you live in one corner of the city, and your office is in the other side, then you wouldn't want to use your bike, you'll want to use the car, which is what you don't want to do.
D. Raising the price of riding the city bus
Not helpful either, this won't help that much, since 1 job will lose, 2nd, people who don't know how to drive or are pregant(probably can't ride a bike) won't be able to travel. And last, it's just so selfish..
So from all these conclusions, we can see that B is truly the answer.Buliding new bike paths in the city.-------------------------------------------------------------------------------------------------------"The beautiful thing about learning is that no one can take it away from you!" B.B.King

A population of 1,000 squirrels live on a farm plot that has an area of 250 square feet. What is the population density?
Answer:
750 square feet
Explanation:
1,000-250=750
And this is the population density.
The population density is equal to 4 people/square feet.
What is the formula for calculating population density?The formula for population density is defined as the number of individuals divided by the area of land given.
Here, number of individuals = 1,000
Area of land = 250 square feet
So, 1000/250 = 4
Therefore, the population density is equal to 4 people/square feet.

If the ability to roll one’s tongue is dominant (r) and the inability to roll one’s tongue is recessive (r), what are the possible genotypes for someone who can roll their tongue? only rr rr and rr rr and rr only rr
The possible genotypes for someone who can roll their tongue are RR or rr, where the R allele is dominant over the r allele.
What do you mean by Genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for a particular study or interest.
If R represents the dominant allele and a person rolls their tongue having this allele, while the r represents the recessive allele and a person can not roll their tongue having this allele. To roll their tongue, a person needs only one dominant allele. Thus the person could have genotypes of RR or Rr.
Therefore, the possible genotypes for someone who can roll their tongue are RR or rr, where the R allele is dominant over the r allele.

Your Opinion and Evidence
Answer:
well I think that it I'd important to use more renewable resource because using much of non renewable sources can cause a shortage of it. it is non renewable
Answer:
Harnessing renewable resources tends to be better for the environment. Non-renewable resources such as fossil fuels produce vast amounts of greenhouse gasses when they are burnt and this contributes to acid rain, climate change and other ecologically harmful effects. By contrast, wind and solar energy do not produce these dangerous gases.
