As trees along a heavily shaded stream are cut down for farm land, the Environmental Protection Agency (EPA) must measure change

s to the local stream habitat. Water samples from the stream are collected over time. The microorganisms are counted and classified in order to track changes.
EPA researchers MOST LIKELY used a __________ to view the microorganisms in the stream water samples.

A)
light microscope


B)
magnifying glass


C)
computer simulation


D)
scanning electron microscope

Answer:

A) light microscope

Explanation:The EPA researchers would use a light microscope to count and classify the microorganisms present in the stream water samples. A magnifying glass would not be strong enough; a scanning electron microscope would be too powerful. A computer simulation does not analyze real data.

Natali [406]

Answer:

2.275% of this population has a diastolic blood pressure less than 60 mmHg

Explanation:

Hello!

Yo have the distribution of the diastolic blood pressure in a certain population. Be X: diastolic blood pressure of an individual, X~N(μ;δ²)

Where

μ= 82mmHg

δ=11 mmHg

You need to calculate the probability of an individual of this population having less than 60mmHg diastolic blood pressure.

Symbolically:

P(X<60)

To obtain the value of probability you need to standardize the value of diastolic pressure so that you can obtain it from the standard normal distribution. The way to standardize the value is to subtract the mean and divide by the standard deviation

Z= (X-μ)/δ~N(0;1)

P(Z<(60-82)/11)

P(Z<-2)= 0.02275

I hope it helps!

construct an explanation for the high incidence of tusklessness in the Gorongosa elephant population.
Setler79 [48]

Answer:

Argument: A trend toward an increased incidence of tusklessness will result in decreased population sizes in the

future.

Claim: In the long term, tusklessness in African elephants is not beneficial to populations, even when heavy

poaching is occurring. So, as tusklessness increases, elephant population sizes will decline.

Evidence: Although poachers kill elephants with tusks, elephants rely on their tusks for survival. Elephants use

their tusks to strip bark off trees for food and to dig up water and minerals from the ground. Male elephants

also use their tusks in competitions with other males for females.

Reasoning: Tuskless elephants are probably not as healthy as those with tusks, as they cannot eat bark off trees

and are unable to dig for water and minerals. During harsh conditions such as droughts, elephants without

tusks would be less likely to survive. Male elephants without tusks are also more likely to be injured during

mating competitions. If too many males are injured or killed, there may be a decline in reproduction.

Over time, many of the tuskless elephants will die or be unable to reproduce, so the population’s size will

decrease.
