The correct answer is - A. 780 GtC.
If the inputs and outputs of carbon are as shown on the image, than the carbon levels in the atmosphere will reduce by 20 GtC in a ten year time, thus making the atmosphere have 780 GtC instead of the initial 800 GtC.
On the image we can see that the carbon that gets up into the atmosphere is 69 GtC annually, while the carbon that returns on the Earth is 71 GtC annually. That means a drop of 2 GtC annually in the carbon levels in the atmosphere.
Such a process will reduce the Greenhouse effect, and eventually it will lead to an ice age because the atmosphere will not be able to retain as much heat as previously, thus the Earth will cool off.
Answer: Wrist
Explanation: The wrist connects the hand to the forearm. It consists of the distal ends of the radius and ulna bones, eight carpal bones, and the proximal ends of five metacarpal bones. This arrangement of bones allows for a wide range of movement.
Answer: option B) 0.25
Explanation:
Total population of four o’clock flowers = 8
Number of red flowers with RR phenotype = 5
Number of pink flowers with Rr phenotype = 2
Number of white flower with rr phenotype = 1
To obtain the phenotype frequency of plants with pink flowers:
put the number or Rr phenotype OVER the total population of four o'clock plants
i.e 2/8
= 0.25
Therefore, 0.25 is the answer
From what I have been taught at any point mutations can occur.
