Answer:
Option B
Explanation:
In biology, fitness refers to the ability of an organism to survive, reproduce, mate and support evolution through gene transfer. A fitness of 0.28 signifies that only 28 percent of a given population are fit physically and able to reproduce while the remaining 72 % are unable to mate and hence cannot reproduce and contribute towards gene flow and evolution.
Hence, option B is correct
Both biome and <span>ecoregion </span>are ecological terms. Biome refers to a major regional group of plant and animal communities adapted to the natural environment. Biome can be of two types: terrestrial(land) andaquatic(water). <span>Ecoregion, </span>which is an abbreviated form of ''ecological region', refers to a smaller class. Each <span>biome </span>consists of severalecoregions, an ecoregion(also called bioregion) covering a realm of land/water having geographically distinctive communities, sharing the same envoronmental conditions and ecological dynamics.
Yes, an ecoregion does consist of different ecologically distinctive communities and species.
Answer:
Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. ... A force has both magnitude and direction, making it a vector quantity.
Therefore, yes
