Answer:
Organisms need carbon for building cells and energy to fuel the process; eukaryotes, in general, all follow the same basic metabolic pathways whereas prokaryotes use a variety of materials and pathways—some employed by no other organisms.

umm well I dont know to. be honest
Answer:
Larger leaf size has a broader surface area with more chloroplasts, absorbs more light from the sun and more number of stomata present on the surface of the leaves, which play a crucial role in gaseous exchange during the process of photosynthesis.
Answer:
recombination and independent segregation of chromosomes during meiosis
Explanation:
Recombination and independent segregation of chromosomes represent the two most important meiotic mechanisms by which sisters from the same parents can inherit different gene variants and therefore look very different from each other:
1- Independent assortment (segregation) of chromosomes: during meiosis, homologous chromosomes are randomly distributed in daughter cells (which will give rise to the gametes), and therefore separate independently of each other. It is for that reason that gametes have unique combinations of chromosomes, which increases genetic variation.
2- Recombination, also known as crossing over, refers to the exchange of chromosome segments between non-sister chromatids during meiosis. This mechanism is well-known to produce new gene variants (alleles) in the daughter cells. In consequence, recombination also increases the genetic variation of the resulting gametes that will produce offspring (in this case, different sisters).
