The vast majority of a tree's carbon comes from the air, which averages 0.03-0.04% by volume (300-400 ppmv) CO2. This is fixed through photosynthesis and eventually stored as glucose which the plant can then use for its metabolism.
Answer:
Yes that can happened you just pick one dog (for example) and pick another dog and breed them
Answer:
Second Punnett on the first attachment.
Explanation:
In a 4 x 4 Punnett there are a total of 4 squares. Twenty five percent (25%) of 4 is 1. This means that only 1 square out of the 4 should have the genotype that you are looking for.
Okay going at it in a biological sense. Because red eyes is dominant, we know that the allele should be represented by a capital R. It is X-linked, so it should be on the X. The problem is looking for the probability of a male offspring so the combination should be XY (this means the offspring is male, XX is for females).
So taking that all together, you're looking for the genotype combination:

So you need to find the Punnett that has only 1 square with this combination. The attachment shows which specific Punnett:
Answer: anagenesis
Explanation:
Evolution in this species has occured within the lineage of a single population
hope this helps : ))
