The answer is b. <span>A decrease in plant life would cause carbon dioxide levels to increase and oxygen levels to decrease.
</span>In the photosynthesis, plants take carbon dioxide and water
and convert it into glucose and oxygen using the energy of sunlight. A decrease of plant life in the biosphere will increase a level of carbon dioxide in the atmosphere. Fewer plants mean fewer photosynthesis processes, and, thus, decreased levels of oxygen in the atmosphere.
Answer:
Nitrogen can be transformed into a utilizable form like NO2 by the fixation process.
Explanation:
The conversion of nitrogen into various chemical forms is described through the Nitrogen cycle. The nitrogen of atmosphere is less usable. However, it can be made usable by various interactions of complex genes that allow nitrogen conversion by different organisms.
One such interactive process is of Fixation. In this method, nitrogen is modified into ammonia by symbiotic microorganism. They have the enzyme called nitrogenase which makes the bond of hydrogen with nitrogen to make ammonia.
Reduction in the amount of energy consumed in a process or system, or by an organization or society, through economy, elimination of waste, and rational use. (e.g. turning lights out when you leave the room)
Answer:
A particular genotype does not necessarily guarantee a particular phenotype. Understanding what factors can change this expression is quite complex.. What is what i believe that above statement meant.
Explanation:
Error is the stochastic variation associated with a particular observation of the phenotype (and is managed by use of replication and and appropriate experimental design). The phenotype is the result not only of the average effect of the different alleles at a given locus across test units and across environments, but is impacted by the interaction between the different alleles and the environments (including genetic backgrounds) in which they are evaluated. Phenotype is not simply the sum of the genotype effect and the environment effect, as indicated in the mathematical formula that you provide.
Hope I Helped!!!
