Answer:
A) Rock climbing
Explanation:
The geosphere of the Earth includes all of its solid parts - the rocks, minerals, and landforms of its surface and interior. If we know this, we can conclude that the activity that involves interaction with the geosphere is rock climbing. Rocks are a part of the geosphere, and as we attempt to climb them, we are interacting with them.
Swimming and sailing are examples of interaction with the hydrosphere.
Riding in an airplane is an example of interaction with the atmosphere.
Herbi= herbs and vores means to eat.
Therefore herbivores feed upon producers which prepare their own food. While carnivores feed upon herbivores.
I think the answer to this is C.
Answer:
c. Methylated CpG islands is associated with long term gene repression.
Explanation:
The CpG sites or islands is a biological term that describes the genomic regions in which CpG sites occur; a region of DNA, in which cytosine nucleotide is followed by a guanine nucleotide in the linear sequence of bases along its 5' → 3' direction.
The CpG islands is characterized with a high frequency of CpG sites, with at least 200 bp, a GC percentage greater than 50%, and an observed-to-expected CpG ratio greater than 60%.
The existence of CpG islands is also associated with low levels of methylation in that genomic area, which has to do with the regulation or repression of gene expression
