Would it be talking about water? In which case the answer would be hydrogen and oxygen.
Answer:
In secondary succession, a previously occupied area is re-colonized following a disturbance that kills much or all of its community. A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire. Wildfires will burn most vegetation and kill animals unable to flee the area.
Answer:
The process that produces gametes is called meiosis. During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. ... At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.
Cohesion helps plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. This transport occurs even in large trees and against gravity. Transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.
1. The dominant trait is yellow peas, whereas the recessive trait is green peas.
Let yellow peas be YY and green peas be Yy
2. the genotype of the parents are YY and Yy.
3. The punnett squares contain the first set of peas and second set.
4. You can see that in the second crossbreed, the different coloured square represents what will become green peas. Thus the ratio would be 3:1.
