Photosynthesis will not occur. The cell will lose its shape and support. Cellular respiration will not take place. Substances will not move in and out of the cell.
Group of answer choices.
A. Weather on Earth's surface
B. Rotation of Earth on its axis
C. Metal liquifying in the inner core
D. Revolutions of Earth around the Sun
E. Rock solidifying in the outer mantle
F. Motion of metal in Earth's outer core
Answer:
B. rotation of Earth on its axis.
F. motion of metal in Earth's outer core.
Explanation:
The phenomena which help form Earth’s magnetic field includes;
I. Rotation of Earth on its axis.
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.
II. Motion of metal in Earth's outer core.
When planet earth spins on its own axis, the iron found within a liquid outer core moves around which typically gives rise to powerful electrical currents to be generated inside the liquid iron.
Answer:
False
Explanation:
Many mentally ill people were made fun of and disrepected because of the way they looked or acted. Parents that had mentally challenged children wouldn't go out in public to save them from embarrassment.
To calculate the total pore space, we will find the difference between the mass of the soil when it is oven - dried and when it is saturated. Therefore, the value of the total pore space and total porosity are 45g and 45% respectively
Given that a 100 cm3 soil core weighs 78g when oven-dried and 123 g when saturated.
The given parameters are;
Volume of soil V = 100
Mass ( Oven dried) 
= 78g
Mass ( Saturated) 
= 123g
In the soil formation, pore space refers to the volume of soil. And to calculate the total pore space, we will find the difference between the mass of the soil when it is oven - dried and when it is saturated. That is,
Total pore space = -
Total pore space = 123 - 78
Total pore space = 45g
And total porosity will be the percentage of the ratio of total pore space to the given volume of the soil. That is,
Total porosity = (Total pore space / volume of the soil) x 100
Total porosity = 45/100 x 100
Total porosity = 0.45 x 100
Total porosity = 45%
Therefore, the value of the total pore space and total porosity are 45g and 45% respectively
