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.

If a sample originally had 120 Adams of carbon 14 how many atoms will remain after 17,190 years

adelina 88 [10]

Answer:

15 atoms

Explanation:

About 15 atoms out of the 120 Adams would remain.

Generally, the half-life of a substance is the time it takes for one-half of that substance to disintegrate.

Carbon 14 has a half-life of approximately 5,730 years. 17,190 years means that the sample had stayed for 17,190/5,730 which is equal to 3 carbon-14 half-lives.

Out of 120 Adams,

the first half-life will reduce 120 to 60 Adams
the second half-life will reduce 60 Adams to 30 Adams
the third half-life will reduce 30 Adams to 15 Adams.

Hence, at the end of the 17,190 years, approximately 15 Adams would remain.

You are given a protein with the following amino acid sequence:

tigry1 [53]

Answer:

d. Lysine is replaced by tryptophan (nonpolar)

Explanation:

Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.

If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.

Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.

Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.

How does an increase in an intake of salt decrease the water content in one's blood? Thank you and please explain your response.

olganol [36]

Eating salt raises the amount of sodium in your bloodstream and wrecks the delicate balance, reducing the ability of your kidneys to remove the water. The result is a higher blood pressure due to the extra fluid and extra strain on the delicate blood vessels leading to the kidneys.
