Some facts about Water erosion :
Water erosion is the detachment and removal of soil material by water. The process may be natural or accelerated by human activity. ... Water erosion wears away the earth's surface. Sheet erosion is the more-or-less uniform removal of soil from the surface.
Water and Wind Erosion (cause)
Water erosion is the removal of soil by water and transportation of the eroded materials away from the point of removal. Water action due to rain erodes the soil and causes activities like gully, rill, and stream erosion leading to the downstream effects of flooding and sedimentation.
Answer:
Option A, C and D
Explanation:
Mutations can be beneficial and call also not be beneficial. Examples of beneficial mutation includes laptop tolerance, HIV resistance etc. This mutations occur as changes in the nucleic acid sequences (DNA; which is made up of the four nitrogenous bases, deoxy/ribose sugar and phosphate group. Changes in these bases can bring about mutations that are beneficial) of organism and also it depends on where in the genetic code they occur. Beneficiary mutations can bring about increased fitness of the organisms involved.
Answer:
Sorry the first one I don't know.
The second one's answer is : Mature nerve cells, cardiac muscle cells, skeletal muscle fibers, fat cells, red blood cells, bone cells (osteocytes), and white blood cells (except lymphocytes) do not undergo division
Eukaryotic cells are cells that have a nuclear envelope, cytoplasmic organelles, and a cytoskeleton.
Prokaryotic cells are cells lacking a nuclear envelope, cytoplasmic organelles, and a cytoskeleton (primarily bacteria).
Also Eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm.
Also Prokaryotic cells are generally smaller and simpler than eukaryotic cells; in addition to the absence of a nucleus, their genomes are less complex and they do not contain cytoplasmic organelles or a cytoskeleton
So the correct answer would be B.
Hope I helped.
Answer:
Open populations occur when the total population is dynamic, with new members leaving and being added over time. ... Closed populations occur when the members of population are fixed and no new members are added or lost from the group (except through birth and death
