Why are flood plain soils particularly fertile
Answers
Answer:
Due to the deposition of silt.
Explanation:
The Floodplain is a generally flat area of land next to a river or stream. When the river floods, water containing sediments and particles from the upper course and middle course of the river gets washed onto the Floodplain. The nutrients front these sediments and the water is absorbed into the soil for it's enrichment and fertilisation.

6. Identify the type of climate data that has the longest data range. 1. microscopic organism 2. data sediment core 3. data tree ring 4. data ice core data
Answers
Complementing data, taken from different sources such as tree rings, sediments, and ice, provides significant information about global climatic changes. However, ice core data has the longest data range. (4) is correct.
-------------------------------
Ice core data refers to the information obtained from a sample of ice taken from a glacier or a mountain.
Information kept in the ice is mostly about gases concentration at different moments though time.
Analysis of retained gases in Antarctic ice, through perforations of over 2000 meters deep, has allowed knowing the CO₂ atmospheric concentrations and other gases involved in the greenhouse effect for at least 150,000 years.
These concentrations have varied in the temporal scale of glaciation, showing low concentrations during glacial periods with low temperature and relatively high concentrations during interglacial periods with high temperature.
Between these two periods, abrupt variations in temperature and gas concentration are detected, meaning that changes in CO₂ cause changes in temperature.
The increase in CO₂ is a highly significant component in global climatic change and possibly the best documented.
This information is the best paleoclimatic documents.
Complementing it with marine sediments core and data tree rings makes it possible to know about the principal traits of terrestrial weather in the lasts 420,000 years, practically four glacial-interglacial cycles.

Explain why the shape of an enzyme is important to its function.
Answers
Answer:
The shape of an enzyme is very important because it has a direct effect on how it catalyzes a reaction.
Each enzyme is folded into a shape that allows the substrate(s) to fit into the active site, which is where the reaction occours. Other substrates do not fit into this active site. This is why each enzyme can only catalyse a specific reaction

Answer:
hi b is the correct one<3 have a good day
Explanation:
Water molecules moving across the plasma membrane until solute concentrations are equal on both sides of the membrane best describes the process of osmosis in an animal cell .
Osmosis is the process in which molecules move from a region of higher concentration to that of a lower concentration across a semi-permeable membrane.
Osmosis provides a balance between the elements in which organisms are exposed to. A very high concentration may cause cells to shrink and die hence the reason to maintain a balance for optimal functions and survival.
