Topographic maps and satellite images

Explanation:

A topographic map represents earth's surface features like land forms and structures, rivers and lakes, mountains and hills, elevations and other natural features along with man-made artificial features like cities, buildings, monuments, roads, bridges etc. These are formed by contour lines.

Topographic maps are printed with revision dates to observe the changes happening on the Earth's surface. Various land forms keeps changing due to natural and man-made causes and these needs to be updated accordingly to provide accurate details.

A satellite image provides details of the earth aerially from space. These provides details of a land form or any earth structure currently.

By comparing with older satellite images or topographic maps with the current one, the changes which occurred over time can be observed.

30% of B-A=18% OF B+A THEN A:B?

dlinn [17]

Answer:

1:4

Explanation:

30%= $\frac{30}{100}$

18%= $\frac{18}{100}$

Rewrite the given information:

$\frac{30}{100} (B - A) = \frac{18}{100}(B + A)$

Multiply by 100 throughout:

30(B -A)= 18(B+A)

Divide by 6 throughout,

5(B -A)= 3(B +A)

Expand

5B -5A= 3B +3A

Bring A terms to 1 side and B terms to another:

5B -3B= 5A +3A

Simplify

2B= 8A

Divide by 2 throughout:

B= 4A

Now, we have to find the ratio of A to B.

B= 4A

Divide by 4 throughout:

A = $= \frac{1}{4} B$

Divide by B on both sides:

$\frac{A}{B} = \frac{1}{4}$

Thus, A:B= 1:4

What is a “strain” of bacteria? How is it possible that some strains of staphylococcus aureus can be harmless, but others can be

cluponka [151]

A strain is a low-level taxonomic rank used at the intraspecific level (within a species). While the majority of the members of the same species have very high similarity in their genomes, there occasionally is a proportion of the species that has a little different genome from the popular species group. This variability results in different strains on the species.

A harmless Staphylococcus aureus may have a muted virulence gene. However, either due to mutation of the gene or recombination with the harmful strain, a harmless Staphylococcus aureus could easily turn virulent (harmful).
