We need to see the bar magnet
Answer:
The correct answer is- secondary treatment
Explanation:
Wastewater treatment is divided into three main stages which are primary, secondary and tertiary stages. In the primary treatment, the wastewater is held in the settling tank for some time and the solid waste settles with time and the remaining liquid is passed for secondary treatment.
In the secondary treatment, the organic compound present in the liquid is degraded with the help of aerobic bacteria. Aeration tank is there for providing the oxygen to bacteria and wastewater is stirred so that oxygen can be distributed evenly and bacteria can do their work properly.
Answer:
Which of the following was concluded by Mendel as a result of his genetic research? Genes for different traits are inherited independently of one another. Nondisjunction can result in the formation of a zygote with three copies of a chromosome.
Explanation:
Answer:
C) The smaller population will be more affected than will the larger population, because the smaller population has less genetic variation than the larger population has.
Explanation:
Genetic variations are present in the natural populations. Some of the genetic traits become adaptive under the changed environmental conditions and allow the individuals carrying them to survive and reproduce. In this way, the genetic variations help to maintain a population.
Therefore, a larger population of a squirrel species with more genetic variations will have less intense impacts of a disturbance/natural calamity and/disease. On the other hand, a smaller population of the same species with a lesser number of squirrels has fewer genetic variations. This population is more likely to be affected in a negative way by a disturbance such as pathogen.
The genetype is the genes that the organism carries the phenotype is the characteristics
