Sea level changes occur at a rate of 10 m per 1,000 years. Regional erosion occurs at a rate of 2 m per 1,000 years. Uplift occu
PtichkaEL [24]
<h3>Answer:</h3>

The rate of sea level change is the fastest

<h3>Explanation:</h3>

To determine the process which is the fastest we need to determine the rate at which each occurs in meters per year.

Rate of sea level changes is 10 m per 1,000 years

Therefore, the rate of sea level change = 10 m ÷ 1000 years

                                                                 = 0.01 m/yr

Regional erosion occurs at 2 m per 1,000 years

Therefore, Rate in meters per seconds = 2 m ÷ 1,000 years

                                                                 = 0.002 m/year

Uplift occurs at a rate of 0.1 m per 1,000 years

Thus, rate in meters per seconds = 0.1 m ÷ 1,000 years

                                                       = 0.0001 m/yr

Therefore, the rate of sea level change is the fastest at a rate of 0.01 meter/year

Before the development of electrophoresis to separate macromolecules, ____________ was used.
max2010maxim [7]

Before the development of electrophoresis to separate macromolecules, high-speed centrifugation was used to isolate DNA.

A laboratory procedure called electrophoresis is used to divide DNA, RNA, or protein molecules according to their size and electrical charge. The molecules are moved by an electric current through a gel or other matrix. The technology of electrophoresis is crucial for the separation and examination of nucleic acids. At the lab bench, cloned DNA fragments are frequently isolated and worked with using nucleic acid electrophoresis.

High-speed centrifugation employs centrifugal force to separate particles with various densities or masses suspended in a liquid. High-speed rotation of the solution inside the tube causes each particle's angular momentum to experience centrifugal forces inversely proportionate to its mass.

What is the boiling point of water at an elevation of 1.55×104 ft ?
horsena [70]
The computation for this problem is:
(1.55x10^4 / 1.0x10^3) x 19.8 mm Hg
= 15.5 x 19.88 mm Hg
= 308.14 mm Hg decrease 
= 308.14 x 0.05 C = 15.407 deg C 
deduct this amount to 100
100 – 15.407 = 84.593 C 
ANSWER: 85 deg C (rounded to 2 significant figures)
