Explanation:
An environment's biology includes both abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem.
These factors lead to a gradual change of an ecosystem over time; however, humans drastically impact the environment through over-exploitation and pollution- we disrupt normal abiotic and biotic interactions.
Oxygen is an inorganic gas that makes up the atmosphere, thus it is abiotic
; it is utilized by animals which undergo cellular respiration to produce energy for life processes. A field mouse may continue to reproduce, increasing the population, and feed on other biotic factors, and aid in nutrient cycling.

Telomerase is involved in adding DNA to the end of the lagging strand.
At the ends of linear chromosomes (telomeres), telomerase uses its built-in RNA template to extend the parent DNA template near the end of the lagging strand, providing room for an RNA primer so that lagging strand synthesis can be completed to the end of the chromosome
A water molecule, in light of its shape, is a polar particle. That is, it has one side that is decidedly charged and one side that is adversely charged. The particle is comprised of two hydrogen iotas and one oxygen molecule. The bonds between the particles are called covalent bonds, on the grounds that the molecules share electrons.
A. a decrease in Oxygen
This is because trees take is Carbon Dioxide and they give off Oxygen. The more that trees are cut down the less oxygen we get.
DNA standard is like a control because it helps to identify the weight of the unknown samples run on electrophoresis gel. It helps to compare the bands of the unknown sample with its own band positions, and we can get the relative weight. DNA ladder consist of many bands whose sizes are known already, so that they can help to find the size of the sample DNA.
Also, a DNA ladder can't be altered during the process of running the DNA in electrophoresis gel.
