The combination processes that can transform a metamorphic rock into sediment are the following;
• Exposure – this is the process where the material is being exposed in weathering conditions and it changes its appearance as time passes by.
• Weathering – this is the process in which the minerals, rocks or soil are being break down with the association of it with the earth’s atmosphere.
• Erosion – this is the action in which is where the rocks, soil or material are being removed and are being relocated into another location.
Answer:
d.during only prophase I and involves exchange between chromatids of homologous chromosomes.
Explanation:
Crossing over is the event that occurs during the pachytene stage of prophase I of meiosis I and results in the formation of new gene combinations, that is, recombination. During pachytene of prophase I, the synapsed homologous chromosomes exchange the genetic segments between them.
To facilitate recombination, synaptonemal complex assists in pairing the homologous chromosomes together during the zygotene stage of prophase I. Zygotene is followed by pachytene. A cut in two non-sister chromatids of a homologous pair, exchange of the broken segments followed by ligation results in recombination. Prophase II does not include crossing over.
<span>Here is the correct option: 'Manatees needs only a few things to survive up to age 60: enough food and to be left alone'. In writing, a colon usually precedes an explanation. Colons are used in English writing to introduce a list of items. In the given example, colon was used to list the needs of Manatees.</span>
