All living creatures are classified into systems and sub-systems based on their similar characteristics. They are divided from bigger groups into smaller groups based on the detail of their similarities i.e. how they look, move, reproduce and how they relate to each other. A practical way of understanding the classification of living organisms is that organisms are linked to other similar organisms via family trees. The classification of all living creatures includes at least four levels: order, families, genus and species.
Answer:
Tan fur helps the mice protect themselves from predators
Explanation:
The entrenchment of this phenotype in the population is powered by natural selection pressures. The mice with fur color that enable them to camouflage with their environment are predated less than mice with other fur colors. These tan mice are therefore more likely to survive and pass their genes to the next generation. Through successive generations, the allelic frequency for the tan fur color increases until it is the dominant allele in the population.
The best answer is B
Deltas are wet lands that form as rivers empty their water and sediments into another body of water such as an ocean, lake, or another river. Deltas can also empty into land although this is less common.
A river moves more slowly as it nears its end. This causes sediment, solid material that has been carried downstream by the water to fall to the river bottom.
The slowing of the river and the build up of sediment allows the river to break up from its single channel to several channels forming a triangular flow at the mouth called a delta.
