Sika have more food choices because they eat both grasses and shrubs, compared to the white-tailed dear who only eats shrubs.
Answer:
this is true about respiration (inhalation and exhalation)
Explanation:
inhalation is the exchange of gas from the environmental oxygen to the oxygen in the tissues.
while Exhalation is the gas exchange of CO2 with O2 (the CO2 is exhales from high concentration to the environment of low concentration.
It represents the end product
Explanation:
Fossil fuel is an overall term for covered ignitable geologic stores of natural materials, framed from rotted plants and creatures that have been changed over to unrefined petroleum, coal, flammable gas, or weighty oils by introduction to warmth and weight in the world's outside more than a huge number of years.
The consuming of petroleum products by people is the biggest wellspring of emanations of carbon dioxide, which is one of the ozone depleting substances that permits radiative compelling and adds to an unnatural weather change.
A little bit of hydrocarbon-based powers are biofuels gotten from climatic carbon dioxide, and consequently don't build the net measure of carbon dioxide in the environment.
Answer:
a)CN=12
b)APF=74 %
c)a=0.35 nm
d)ρ=9090.9
Explanation:
Given that
Nickel have FCC structure
We know that in FCC structure ,in FCC 8 atoms at corner with 1/8 th part in one unit cell and 6 atoms at faces with 1/2 part in one unit cell .
Z=8 x 1/8 + 1/2 x 6 =4
Z=4
Coordination number (CN)
The number of atoms which touch the second atoms is known as coordination number.In other word the number of nearest atoms.
CN=12
Coordination number of FCC structure is 12.These 12 atoms are 4 atoms at the at corner ,4 atoms at 4 faces and 4 atoms of next unit cell.
APF
We know that for FCC
Now by putting the values
APF=0.74
APF=74 %
a=0.35 nm
Density
We know that M for Ni
M=58.69 g/mol
a=0.35 nm
ρ=9090.9
