O-H bond is referred to as the most polar.
Explanation:
O-H bond is said to be most polar because the electronegativity is different. Electronegativity can be said as the atom's ability to attract electrons towards itself. Electronegativity of an atom increases when there is a movement on the periodic table from left to right.
When the electronegativity between the atoms are different then it is said to be a polar bond on the other case if the electronegativity between the atoms are same it is said to be non- polar bonds.
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
The identity of the person belonging to said DNA. Although in actuality, the lab tech is the person who performs this task. Also <span>so they could find out who is the murder, thief or someone who did the crime but it would it would be sent to a lad re-searcher person to do the actual work to find out who did the crime!</span>
Answer:
Water and temperature
Explanation:
Water and temperature are the two most important factors that regulate the distribution of organisms in terrestrial habitats. Water is required for survival by living beings. The availability of water is limited in many habitats such as desert habitats. In such land habitats with water scarcity, the organisms adapted to withstand the limited water availability are found.
Likewise, temperature also affects the distribution of organisms in terrestrial habitats. The presence of temperature conditions below and above the tolerance range of the organisms restricts their geographical distribution. Temperature regulates the enzyme kinetics. Metabolic pathways are catalyzed by enzymes that function under optimal temperature conditions only. Water serves as a medium for metabolic reactions and also regulates body temperature.
Because cells need insulin for glucose from the blood if they don’t have enough glucose it can build up in the blood and that causes the tiredness. Glucose is needed to create energy otherwise you would end up tired.
