The biotic factors are the living components of an ecosystem and are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.
Abiotic factors come in all types and can vary among different ecosystems. For example, abiotic factors found in aquatic systems may be things like water depth, pH, sunlight, turbidity (amount of water cloudiness), salinity (salt concentration), available nutrients (nitrogen, phosphorous, etc.), and dissolved oxygen (amount of oxygen dissolved in the water). Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight
Answer: uncontrollably cell proliferation
Explanation: the human egfr (spiderman growth factor receptor) being a proud-oncogene is involved in the regulation of cell division, development and differentiation thus mutation of the egfr allele will activate the proto oncogene and change it to an oncogene. Oncogenes are dominant structural genes that encodes protein which can alter the phenotype of a cell. This mutated egfr allele becomes an oncogene producing mutated cells which will continue to undergo uncontrolled cell division/proliferation
The graph that best shows the general relationship between the temperature of a gas and the speed of the molecules in that gas is B.
<h3>What is kinetic energy?</h3>
Kinetic energy is the energy that an object or particle has as a result of its motion. When work transferring energy, is done on an object by applying a net force, the object accelerates and goes under kinetic energy.
The missing graphs are attached as image.
The average kinetic energy of gas molecules is
K∝T
So as per above equation, K-T graph is a straight line having a finite slope and passing through the origin.
Thus, option B is correct.

Answer:
reduce the amount of fossil fuels they combust
Explanation:
Fossil fuels lead to environmental damage and its burning releases a lot of pollutants especially carbon and sulphur oxide to the air. The carbon increase in the atmosphere may lead to global warming because of the so-called greenhouse effect. To reduce carbon by returning to the normal cycle, humans can reduce the amount of fossil fuels they combust, try converting solid coal to gas or liquid and for removing pollutants or alternatively used renewable energy sources that are less pollutant.
Nitrogen fixation- atmospheric nitrogen is assimilated into organic compounds especially by certain microorganisms as part of the nitrogen cycle.
