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.

Explanation:
Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. ... Your kidneys, ureters, and bladder are part of your urinary tract. You have two kidneys that filter your blood, removing wastes and extra water to make urine.
<u>Answer:</u>
<u>Haploid cells join to form an organism that has a complete set of chromosomes is the correct answer.</u>
<u></u>
<u>Explanation:</u>
<u>In the fertilization process two haploid cells sperm fuse with an egg which results in the formation of a diploid cell.</u>
<u></u>
<u>meiosis produces haploid cells rather than diploid cells because in Meiosis the chromosome number gets reduced.</u>
<u></u>
<u>In the Meiosis process the number of chromosomes in the daughter cells gets reduced to half than of the parent cell and this process results in the formation of four haploid daughter cells</u>
<u></u>
<u>So Haploid cells join to form an organism that has a complete set of chromosomes is the correct answer.</u>
