Inadequate circulation of blood through out the body is referred to as shock or hypoperfusion. Adequate supply of blood to body tissues is important as it supplies oxygen and nutrients and collect waste materials from the tissues. Limited/ inadequate supply of blood to various organ tissues such as the legs, hands, heart and rest of the body, including the fingers may cause a shock. Inadequate supply of blood mainly results from the blockage of blood vessels by the build up of fatty substance (plaque) in the vessels causing hardening and constriction of the wall of veins and arteries.
A=P(1/2)^(t/h)
A=final amount
P=initial amount
t=time
h=half life
so
h=1.3 billlion (just write 1.3 and remember to mulipy the end time by 1 billion)
and final amount is 25% of original or 0.25P
0.25P=P(1/2)^(t/1.3)
divide both sides by P
0.25=(1/2)^(t/1.3)
take ln of bot sides
ln(0.25)=ln((1/2)^(t/1.3))
property of logarithms
ln(0.25)=(t/1.3)ln(1/2)
divide both sides by ln(1/2)
(ln(0.25))/(ln(1/2))=t/1.3
times both sides by 1.3
(1.3ln(0.25))/(ln(1/2))=t
remember that this is billion so
(1,300,000,000ln(0.25))/(ln(1/2))=t
2600000000.0001=t
about 2.6 billion years
Answer: Flowering plant life cycle
Explanation:
hope this helps !!!!
The influence of climate is due to basically two factors: temperature and rainfall. Climate indirectly affects soil formation through its influence on organisms as well. High temperatures and rainfall increase the degree of weathering and therefore the extent of soil development.
The first one is d, the second is c.
