Chromosomes exchange genetic material in step 3.
<h3><u>Explanation</u>:</h3>
The meiosis is the type of cell division that takes place for gametogenesis. The meiosis has two phases - meiosis I and meiosis II.
The meiosis I has the events like crossing over and independent assortment which leads to the mixing of genes between homologous chromosome pairs and separation of homologous chromosome pairs. So the two cells that are produced from the meiosis I are genetically different. The step 3 shows the crossing over of prophase 1 of meiosis I. So, it shows the genetic difference between the offsprings and leads to genetic variation.
Invasive firestorm method. All pests are now dead with the added benefit of fewer trees to infest.
Answer: Brain
Explanation:
The DTI technique is useful for examining the brain. It is a used to observe the neuropathology and associated treatment. It is used to examine the pathology of brain such as axonal damage, edema, inflammation, and iscemia myelination.
