Answer:
a) b + i = d + e
b) b + i < d + e
c) b + i > d + e
Explanation:
Data provided in the question:
b = birth
d = deaths
i = immigration
e = emigration
Now,
a) a population in equilibrium
this means increase in population is equal to decrease in population
i.e
b + i = d + e
b) b) a declining population
this means increase in population is less than decrease in population
i.e
b + i < d + e
c) an increasing population
this means increase in population is increase in decrease in population
i.e
b + i > d + e
Answer:
The plants took in more CO2 and 'exhaled'/released oxygen. This occurs during photosynthesis, so we can therefore deduce photosynthesis was occurring
The given case is an example of reflex action.
The reflex action is an instant involuntary response to a stimuli, which can cause damage. The reflex action takes place through the processing of message through a reflex arc, this reflex arc lack the involvement of brain and the processing of the stimulus takes place in the spinal cord.
In this case, the sensory receptors detects the stimuli and transfer the message to the relay neuron present in the spinal cord through the sensory neuron. The relay neuron transfer the action message to the effector muscles present at the site of stimulus with the help of motor neurons.
Given below is a block diagram of reflex action.
Answer:
Parasitism
Explanation:

Host - the one being harmed in parasitism in this case the fish.
Parasite - the organism (the one doing the harm) that benefits in parasitsm in this case the leech.
