Ecologists are the persons who study the interrelationships between organisms and their environments. Like they research upon the species found in forests or deserts interact with each other and as well as their surroundings.
They test whether a species is occupying its complete fundamental niche or only a portion of it by observing if the species are expanding their range after the removal of a competitor because two species with the same fundamental niche will exclude other competing species.
Answer:
option D is incorrect
Explanation:
the sedimentation coefficient is measured in Svedberg units named after the scientist Theodore Svedberg. the shape of the particle being measured in the ultracentrifuge is one of the factors that determines the sedimentation coefficient. the values are usually not additive as the sedimentation coefficient is based on the rate at which a particle sediments in an ultracentrifuge and not on the size. for example, the sedimentation coefficient of eukaryotic ribosome is 80S but is made up of the 60S large subunit and the 40S small subunit.
Answer:
Transferred to a different chromosome without a reciprocal exchange of genetic material
Explanation:
Translocation is one of the structural abnormalities of chromosomes. During translocation, a segment from the chromosome breaks off and attaches to the non-homologous chromosome. Translocation can be reciprocal or nonreciprocal.
In reciprocal translocation, the exchange of chromosomal segments occurs between two non-homologous chromosomes. On the other hand, the nonreciprocal translocation, one chromosome loses its segment to a non-homologous chromosome but does not get the same from the recipient chromosome.

Similar groups of function is called "Tissues"
