The water cycle is important to all life on earth for many reasons.
The water cycle is important to all life on earth for many reasons. All living organisms require water and the water cycle describes the process of how water moves through the planet.
Plants wouldn't grow without precipitation (and thus anything consuming the plants wouldn't survive and so forth). Infiltration of water filters and cleans our water. Glaciers, ice, and snow can act as stores of freshwater for both humans and other organisms. Runoff contributes to rivers, other freshwater bodies, and eventually the ocean, sustaining freshwater and marine life.
All of these process sustain life and create the ecosystems around us. Some organisms are very sensitive to changes in the water cycle. A prolonged drought can destroy a population of plants or a certain salamander species may require a set amount of soil saturation in order to avoid desiccation.
See this question on how humans use water in everyday life, this webpage from NASA on the water cycle, and this PDF on how the natural world filters water for more information on why the water cycle is so important.
In Calvin cycle or dark reaction, sugars are formed by using the chemical energy of
Equation for dark reaction:
Diagram of Calvin cycle:
Steps in Calvin Cycle:
1st step: Carbon fixation:
It refers to the initial incorporation of
Calvin cycle begins by the reaction of CO2 with highly reactive phosphorylated five carbon-sugar named ribulose bisphosphate(RuBP).
This reaction is catalyzed by the enzyme ribulose bisphosphate carboxylase also known as Rubisco .
2nd step: Reduction:
In this step, fixed carbon is reduced to energy rich G3P with the energy and reducing power of ATP and NADPH respectively.
Each molecule of PGA recieves an additional phosphate from ATP of light reaction and form 1,3-bisphosphoglycerate.
It is reduced to glyceraldehyde 3-phosphate(G3P) by recieving a pair of electrons donated from NADPH of light reactions.
Actually G3P is the carbohydrate that is produced directly from Calvin cycle.
Because out of every
3rd step: Regeneration of
Through a complex series of reactions, the carbon skeletons of five molecules of three-carbon G3P are rearranged into three molecules of five-carbon ribulose phosphate(RuP).
Each RuP is phosphorylated to RuBP. Again
These RuBP are now prepared to recieve
Because we have a double set of Chromosomes.
If a gene is recessive it usually is broken/inactive/damaged.
As long as you have a dominant, proper working gene on the corresponding chromosome donated by your other parent, you will survive and pass the recessive gene on to the next generation...
Though not necessarily lethal anymore these days, Haemophilia is a relatively good example: This is caused by a defective gene that normally codes for FactorVIII (8), an essential factor in bloodclotting.
It resides on the X-chromosome....
Females have 2 X-chromosomes, so if one carries a defective gene, it will be compensated for by the other chromosome.
Males aren't so lucky: They receive an X-chromosome from their mother and a Y-chromosome from their father.
The Y-chromosome doesn't contain the FactorVIII gene, so if you inherit a defective one from your mother ( on the X-chromosome she contributed), you're in trouble....
Females who have a defective gene on one of their X-chromosomes won't be Haemophiliac, but they are a Carrier.
Occasionally a female CAN inherit TWO X-chromosomes that have defective FVIII-genes, and then she will be affected, but the chance is much lower...
men, medicine, rifles, ships.
Grant could afford to lose battle after battle to Lee in his drive to Petersburg, because Grant could replace his loses, while the south could not Because of immigration the north had much larger supplies of replacement soldiers.
Because of the anaconda plan the south was blocked from imports. The south was not able to get medical supplies like opium and other medical supplies. Many soldiers died or loss limbs in the south because of the lack of medical supplies. Sadly many soldiers in the north became addicted to opium. The over supply of medical supplies in the north had some negative consequences.
rifles, cannons, were produced in factories in the north. Also the north could import arms from Europe. The south had a few factories that could produce weapons. The blockade meant that it was difficult for the south to import arms from Europe. After the fall of Vicksburg the south could not get any further arms from Europe. The soldiers in the north had access to repeating rifles, better muskets, Parrot cannons, colt revolvers, and sharp shooting rifles with scopes. All of the weapons that the northern army used were superior to the weapons available to the soldiers in the southern armies.
The armored gun boats of the Union dominated the Mississippi River conflict. The blockade was possible because the Union had many more ships than were available to the south.
In the Ideal Gas Law formula, there are 3 variables and 2 constants.
This is a "classic" related rates problem. We need to take derivatives of every variable (
We have all of the values we need provided to us to substitute into this related rates expression:
A quick "sanity check" verifies that the sign of our answer is what we'd expect. Since P is inversely related to V and directly related to T, if the volume is decreasing, and the temperature is increasing, we'd definitely expect the pressure P to be increasing (positive). Since
Mexico consists of an entire mountain system known as the Sierra Madre. The three ranges it consists of are called Sierra Madre Occidental, Sierra Madre Oriental, and Sierra Madre del Sur.
The mountain system is located in central Mexico. "Western" in Spanish is "occidental," meaning Sierra Madre Occidental is to the west. "Eastern" in Spanish is "oriental," meaning Sierra Madre Oriental is to the east. "Southern" in Spanish is "del sur," meaning Sierra Madre del Sur is to the south.
Fun Fact: Sierra Madre Oriental contains the largest point in Mexico called the Pico de Orizaba (or "Peak of Orizaba [Mexican city]").
Convert them into the same form. Decimals are easiest to compare.
The two negative values are equal and are the smallest.

We have 56 cents + 0.479 cents
so the 'cut off' point is the red part
We look at the first digit only that is immediately to the right of the cut off point. In this case it is the four
This is the rule:
If this digit is less than 5 we do not change the red part.
If the digit is 5 or more we increase the red part by 1.

Making up a another value I choose
is less than 5 so we do not change the red part.
