If the Arctic became completely ice-free and phytoplankton productivity levels were maintained, Arrigo and his colleagues calculated that the new carbon sink could in theory absorb an extra 160 million tonnes of carbon each year.
Answer:
The correct answer is - DNA (check image).
Explanation:
In this diagram, The W mark is the nucleus of the cell X is the chromosome Y represents the DNA and Z is the gene. Gene is the segment of the DNA and DNA is the pat of the chromosome with histone. Chromosomes are present in the nucleus of the cell. These all are the structures of the genetic structures.
Thus, the correct answer is - DNA.
It will take
7.5 s for the car to stop.
One of the acceleration formulas is

+at, where

is the final velocity,

is the initial velocity,
a is the acceleration, and
t is the time.
0 = 30.0 m·s⁻¹ + (-4.0 m·s⁻²)t
4.0 s⁻¹ t = 30.0
t =

= 7.5 s
Answer:
The answer is "Greater than zero, and greater than the rate of the reverse reaction".
Explanation:
It applies a rate of reaction to the balance, a forward response dominates until it reaches a constant. This process is balanced before 52 mmol of the reactant
, to which 3 is added. In balance, that rate of the forward reaction was its rate with forwarding reaction, both of which are higher than 0 as the response has achieved balance so that both species get a level greater than 0.
