The atoms of different elements all have different numbers of protons. Meanwhile, the mass number of an atom consists of the total number of protons and neutrons it contains. An atom's mass number can never be smaller than its atomic number, and while it can be the same it is normally larger.

As altitude increases, air pressure __________ (increases, decreases, or stays the same). This is a(n) ________(direct, indirect
lions [1.4K]

Answer:

The correct answer is - decreases. direct.

Explanation:

Altitude is a distance measurement of distance in a vertical manner or how high something from the sea level. It helps in the height of the mountains and different places.

Air pressure and altitude are the two factors that are in direct relation as the air pressure decreases with the increase in altitude. the gases present in the higher elevations are fewer than the sea level.

Describe the connection between a mountain range and a rain shadow. This illustration shows the cross section of a segment of mo
Soloha48 [4]
Wind and moist air are drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances across the mountains creating a drier side called the "rain shadow".

Mountains can have a significant effect on rainfall. When air reaches the mountains, it is forced to rise over this barrier. As the air moves up the windward side of a mountain, it cools, and the volume decreases. As a result, humidity increases and orographic clouds and precipitation can develop.

Powered by. A rain shadow is a patch of land that has been forced to become a desert because mountain ranges blocked all plant-growing, rainy weather. On one side of the mountain, wet weather systems drop rain and snow. On the other side of the mountain—the rain shadow side—all that precipitation is blocked.

What is the approximate Km for the enzyme? Explain.
prohojiy [21]

Answer:

The rate of reaction when the enzyme is saturated with substrate is the maximum rate of reaction, Vmax. ... This is usually expressed as the Km (Michaelis constant) of the enzyme, an inverse measure of affinity. For practical purposes, Km is the concentration of substrate which permits the enzyme to achieve half Vmax.

The half life of Carbon 14 is 5500 years. How many years will pass for a 30 gram sample to reach 3.75 grams
sertanlavr [38]
Half life is the time taken by a radioactive isotope to decay by half of its original mass. In this case the half life of carbon-14 is 5500 years. 
The original mass is 30 g and the new mass is 3.75 g. 
New mass = Original mass × (1/2)^n, where n is the number of half lives; 
3.75 = 30 × (1/2)^n
 1/8 = (1/2)^n
 n = 3 
Thus, the time taken will be; 3 × 5500 = 16500 years.
