Answer:
The growth rate for given set of population is 14
Explanation:
Given in question,
births = 20
deaths = 10
immigration = 5
emigration = 1
Growth rate shall be given by following equation -
Growth rate = (Number of births) + (Number of Immigration) - (Number of deaths) - ( Number of emigration)
Substituting the given values in above equation, we get -
Growth = 
The growth rate for given set of population is 14
Bcoz.. In meiosis ti change ploidy of cell from diploid(n) to haploid(2n) .. 2 division occur.. This helps in formation of haploid gametes.. When two gametes fuse.. They form diploid (2n) zygote.
On the other hand..
There is only one division in mitosis...bcoz no change in ploidy.. Use in growth. Bcoz it retains nucleo-cytoplasmic ratio.
Parasites are mostly associated with meats ,Chicken would be the most common answer.
In photosynthesis experiment, the effect of the light will be observe during the starch production- thus you need to have a plant without a starch to observe if the starch is produced during photosynthesis. Letting the leaves of the plant deprived from light for 48 hours will be forced to use its reserved starch making the storage of the starch decrease.
