Answer:
Signal transduction pathways
Explanation:
Plant hormones act by directly affecting the activities of signal transduction pathways.
Signal transduction pathways are involved in the transfer of signals from outside of the cell to the inside of the cell for the regulation of various cellular activities. For this, the extracellular signalling molecules bind to the receptors that are located on the cell membrane. After their binding due to some change in the receptor molecule, a signal is triggered in to the cell and thus information from outside of the cell is transferred to the inside of the cell through these transduction pathways.
Plant hormones affect these pathways and as a result membranes, enzymes, and genes are also influenced by the plant hormones.

Answer:
The food chain that is described in the question is called Grazing food chain.
Explanation:
Grazing food chain is a type of food chain that contain producers at the lowest tropic level.The producers can manufacture their own food by photosynthesis process. Here grass act as producers.
The second topic level of grazing food chain contain primary consumers which consume producer. Here grasshopper eat grass,as a result grasshopper act as primary consumers or herbivores
The third tropic level of grazing food chain contain secondary consumers that feed on primary consumers. Here snake eats grasshopper,as a result snake act as secondary consumers or primary carnivores.
The highest tropic level of grazing food chain contain tertiary consumers or secondary carnivores.Hawk eats snake,as a result hawk act as Tertiary consumers or secondary carnivores.
Answer:
LD50 (median lethal dose)
Explanation:
- Whenever one needs to quantify the virulence of a pathogen then this is done by using a set of laboratory animals.
- LD50 (median lethal dose) is an important indicator of virulence.
- LD50 is defined as the number of pathogens that are required to kill 50% of the total infected animals.
- For the calculation of LD50, the animals are infected with a known number of pathogens and then a graph is plotted for the percentage of animals killed against the concentration of the pathogen used for infection.<em> The point at which the graph indicates the death of 50% animals, the corresponding concentration of inoculation of a pathogen is taken as the LD50 of that particular pathogen. </em>
