Upland Zone: This zone sets back from the lake. It starts where the Buffer Zone ends 35 feet from the top of the shoreline bank.
Buffer Zone: This zone is immediately next to the lake.
Shoreline Zone: This is the transition zone from water to land.
I am not sure on this question
They are similar because they are both located near the same parallel on the opposite hemisphere. Imagine it like like a mirror. From the North pole towards the equator the climate changes, and then it is mirrored in the southern hemisphere going from the equator towards Antarctica. They are located in the same parts of their respective hemispheres.
Answer:
D) All of the above are true.
Explanation:
Wetlands are the regions of land which are covered by water. The water can be fresh water, Saltish water or between these two. Low-lying areas of rivers or oceans, ponds, lakes and marshes, all fall under wetlands.
- Wetlands are extremely important for the life on earth because of immense number of services they provide to humans, wildlife and fish. They are more productive region than coral reefs and rain forests.
- They have an important role in protecting the shores from the strong action of waves that can cause floods. They also help in trapping sediments and thus lowering the losses due to soil erosion. This makes option A true.
- They provide habitat and food source to wide array of organisms such as fish and wildlife therefore option B is also true.
- They also help in the controlling of pollution because they clean or filter sediment from runoff water which ultimately helps in preventing mud clogging in water reservoirs such as lakes. Therefore, they have a cleansing or filtration action and this makes option C true.
Hence, D is the best option.
Hope it helps!
Answer:
The correct answer is ''can change over time in response to environmental cues, allowing genes to be turned on or off as needed.''
Explanation:
Histones are a family of proteins involved in compacting DNA into structural units called nucleosomes. Histone modifications occur in response to environmental conditions, and modulate the structure of chromatin, that is, they alter the structure of nucleosomes and therefore chromatin, and thus activate the transcription process, in which the chromatin is in the euchromatin state (loose conformation, in which the DNA information can be read), or "off" state, in which the chromatin adopts the heterochromatin conformation (compact conformation, which prevents reading), respectively. These post-translational modifications are mainly acetylation, methylation, phosphorylation, although there are many others. These make up the “histone code” that can change the expression pattern of some genes by modifying the chromatin structure, activating or silencing these genes.
