Explanation:
Homologous chromosomes are 2 physically different chromosomes that have the same genes but are not genetically identical. Sister chromatids are 2 copies of a single chromosome and so are genetically identical (they also are physically attached to one another).
Answer: equilibrium phenomenon
Explanation:
Sugar cane has a lot of iron in it which helps oxygen distribution in the brain.
The idea behind an available niche after extinction leading to speciation is: the fact that those species can grow distinct and then in other to survive develop new traits.
<h3>Meaning of speciation</h3>
Speciation can be defined as a process that births new species with different traits while they evolve.
Speciation occurs when extinction is eminent and most time in other to preserve that race they evolve into something new with new traits.
In conclusion, The idea behind an available niche after extinction leading to speciation is: the fact that those species can grow distinct and then in other to survive develop new traits.

Answer:
DNA ligase
Explanation:
<em>The biochemist must have left out DNA ligase enzyme.</em>
<u>The DNA ligase enzyme is able to catalyze the formation of phosphodiester bonds and as such, capable of joining strands of DNA together to form a single strand.</u>
The numerous DNA segments of a few nucleotides long observed by the biochemist must have been the replicated product of the lagging DNA strand. The lagging strand is replicated discontinuously in short strands because the DNA polymerase enzyme can only elongate primers in 5' to 3' direction. The short segments are known as Okazaki segments and are usually joined together to form a whole strand by the DNA ligase enzyme.
Hence, the missing component is the DNA ligase.
