Triss [41]
<h3><u>Question</u><u>:</u><u>-</u></h3>

After nitrogen becomes part of the lithosphere, the next change the nitrogen will under go is it will be:-

A. used as a nutrient by plants

B. fix by bacteria in the soil

C. absorbed into the atmosphere by lightning

<h3><u>Answer</u><u>:</u><u>-</u></h3>

B. fix by bacteria in the soil

<h3><u>Explanation</u><u>:</u><u>-</u></h3>

  • These bacteria are known as nitrogen-fixing bacteria.
  • These nitrogen-fixing bacteria convert nitrogen in the soil to ammonia. Ammonia can be taken up by plants.

Secondly, explain why energy is not just provided by the simple hydrolysis of ATP.
Nataliya [291]

Answer:

The exergonic reaction of hydrolysis of ATP must be coupled to an endergonic reaction to perform work or to power other reactions.

Explanation:

ATP (adenosin triphosphate) is hydrolized to give ADP and releases energy as follows:

ATP + H₂O ⇆ ADP + Pi + energy

The released energy itself is not used to power biochemical reaction. In order to power other reactions, ATP hydrolysis- a energetically favorable reaction- is coupled to another energetically disfavorable reaction. The linking or coupling is performed through a shared intermediate, which is often a phosphorilated molecule. For example, in the formation reaction of sucrose from glucose and fructose, an intermediate is formated by the transfer of a phosphate group (Pi) provided by ATP hydrolysis. Then, the phosphorilated intermediate (glucose-Pi)- wich is unstable- reacts with fructose in a spontaneous reaction to give sucrose.

xeze [42]

Answer:

The process that Mildred used is known as Radiocarbon dating

Note: The question is incomplete. The complete question is given below:

Mildred collects a sample of fossilized plant material. She takes it back to her lab to run some tests on it. Mildred is able to measure the amount of carbon-14 in her sample and compare this to the amount of carbon-12 in it. She uses this information to calculate that the fossil is 4,500 year old. The process that Mildred used is known as _______

Radiocarbon dating

Faulting

Indexing

Superposition

Explanation:

Radiocarbon dating is a process of determining the age estimates of various objects and materials using the radioactive properties of an isotope of carbon, carbon-14.

Radiocarbon dating uses the ratio of two isotopes of carbon, carbon-12 and carbon-14 present in materials which contains carbon to determine their age.

There is a fairly constant ratio of carbon-12 and carbon-14 in living organisms. However, at death, due to the decay of carbon-14 to carbon-12, the ratio begins to change. Since the rate of decay of carbon-14 is fairly constant, a property known as half-life, the time it has taken for carbon-14 to decay to carbon-12 can be calculated. This calculated time will givee the age of the fossilised material.
