DNA<span> is transcribed into RNA, 1 base of </span>DNA<span> corresponds to 1 base of RNA, this 1 to 1 relation is not used in the translation to </span>protein<span>. During this translation, 1 amino acid is added to the </span>protein strand for every 3 bases in the RNA so b<span>efore double stranded </span>DNA<span> is turned into </span>protein<span> it first goes through a process called transcription. </span>
Answer:
C. Mutations always cause a change in the in the way an organism looks.
Explanation:
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.
This procedure is called a vacuum extraction or vacuum assisted delivery. In vacuum assisted delivery, the healthcare practitioner uses a vacuum device with a cup with a handle and a vacuum pump to expedite the delivery of the baby. The vacuum assisted delivery is indicated in mothers undergoing labor for a longer time than normal; with inadequate contractions and failure of cervical dilatation to progress.
