Answer:
0.78
Explanation:
Fitness measures the probability of survival and reproduction of a particular phenotype or genotype in a population.
Relative fitness measures how fit one genotype or phenotype is with respect to the most fit genotype or phenotype in a popualtion. It is calculated as = survival rate of that group / maximum survival rate observed in that population
Here,
Total number of yellow birds = 263
Yellows birds that survived = 150
Survival rate of yellow birds = 150/263 = 0.57
Total number of grey birds = 413
Grey birds that survived = 303
Survival rate of grey birds = 303/413 = 0.73
Grey birds have more survival rate than yellow birds so their survival rate is maximum in the population.
Fitness of yellow phenotype relative to grey phenotype = survival rate of yellow birds / survival rate of grey birds
= 0.57 / 0.73
= 0.78
Hence, fitness of the yellow phenotype relative to the grey one is 0.78.

They reproduce using spores not seeds
Answer:
Wilting occurs due to excess removal of water from plant body.
Crop rotation.
Explanation:
The main use of blue green algae is that it has the ability of fixing atmospheric nitrogen for the plants. Oil is extracted from Neem leaves which is used as fungicide and pesticide for plants. Turmeric is used as healing of wounds for both plants and animals. It also prevent fungal and bacterial disease in plants. Plants will wilt if not watered because water is removed from the body of plants in order to cool down the inner temperature so due to removal of excess water from plant body it will dry and start wilting. Crop rotation is used in these cropping system. Crop rotation is a practice of growing more than one crop on the same piece of land in a year.
