Answer:
Answer is A. allow them to control all the variables involved.
Explanation:
Modelling in ecology means the use of constructed mathematical models for understanding of ecological processes and to predict or know how real it is for ecosystem to change.
Ecological modelling is useful in defining problems more precisely and clarity of concepts.
The rate would increase because more molecules would collide at the activation energy, which will cause more molecules to react, and thus it will speed up the reaction rate.
Answer:
Answer is C
Explanation:
Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes leading to a variety of cells
The correct answer is option D, that is, look for soil bacteria, which transforms nitrates into nitrogen gas.
A microbial mediated procedure where nitrate is reduced and eventually generating molecular nitrogen via an array of intermediate gaseous nitrogen gaseous outcomes is known as denitrification.
It is generally the withdrawal or the loss of nitrogen or nitrogen components, mainly the reduction of nitrites or nitrates by the bacteria in the soil, which usually leads to the escape of nitrogen into the atmosphere.
Answer:
Explanation:
quadrant to determine the population of plants. The quadrants is square in shape and its been marked with boundaries. It is place on a particular location to determine the number of plants.
Population of owl in 2000 =200 owl
Population of owl in 2004 =126 owl
Change in population = 200 -126=74 plants
There is a decrease by 74 in the number of plant.
