In some oceans, large underwater mountains exist. Corals inhabit some areas of these underwater mountains but not others. Scient

ists studied the effect of the presence of corals on the types of other organisms in these habitats. To do this, they collected water samples from areas with corals and areas without corals and compared the organisms found in each sample. How does this method of sampling help determine the effect of the presence of corals on the types of other organisms?A. by comparing the populations of organisms found in the samples from the two areasB. by comparing the lifespans of the organisms found in the samples from the two areasC. by comparing the average size of the organisms found in the samples from the two areasD. by comparing the average mass of the organisms found in the samples from the two areas

The study aims to understand the effect of the presence of corals on the types of organisms, not specially on the size, lifespan or mass. It would be important, then, to understand the different types of populations found in the two areas, because a population is a group of organisms from the same species. Therefore, understanding the populations would mean understanding what are the types of organisms in each area.

So the correct answer is A. by comparing the populations of organisms found in the samples from the two areas

describe the role of deep fascia in compartmentalizing the segments of the limbs (i.e., arm, forearm, thigh, leg).
Brilliant_brown [7]

The role of deep fascia in compartmentalizing the segments of the limbs is to transmits the load between bones and intermuscular septa.

These compartment are known as osteofascial compartment, these compartment forms by the fascia that enables the means of containing and separating the groups of muscles into relatively well defined spaces that are compartment.

The deep fascia helps to support and protect muscles and other soft tissue structure. Also it provide a barrier against the infection from one skin to another. The fascia is a structure of connective tissue that surrounds muscles, groups of vessels and nerves.

The convection that causes Earth's magnetic field happens in Earth's _____.
adelina 88 [10]
The answer is the outer core. 

The outer core of the Earth is made up of liquid metal. The liquid in the outer core pass through the magnetic field and this causes the flow of electric current with in it. The magnetic field gets stronger as the liquid metal passes through it. What makes the liquid metal move is the inner core. It heats up the outer core which triggers convection.

Genetic variation in bacterial populations cannot result from
zmey [24]

Answer:

Meiosis

Explanation:

Gene recombination refers to the mixture of genes from different individuals that occurs during sexual reproduction. Gene recombination is responsible for mixing between genes, which results in genetic variation in a bacterial population.

Genetic variability in a bacterial population occurs through three types of mechanisms: transformation, conjugation and transduction. However this genetic variation does not occur through Meiosis.

Transformation is the incorporation of free DNA by the bacterial cell. Conjugation is the process of transferring DNA from one bacterium to another, involving contact between the two cells. Transduction is the transfer of genetic material between cells, mediated by bacteriophages.

Convert 96.5 decaliters to hectoliters. 0.965 hectoliters 9.65 hectoliters 965 hectoliters 9,650 hectoliters
SIZIF [17.4K]

Answer:

Option B, 9.65 hectoliters

Explanation:

As we know that in one hectoliter there are ten decaliters

1 hectoliter = 10 decaliters

or

1  decaliters = \frac{1}{10} hectoliter

For converting any small unit into a large unit it is to be divided by number of units in large unit.

Thus,

96.5  decaliters  in terms of hectoliter is equal to

\frac{96.5}{10} \\= 9.65

Hence, option B is correct
