For a given po₂, hemoglobin unloads more oxygen at ____________ temperatures.

1 answer:

6 0

temp-hgher temp results in more unloading bohr effect-A more active tissue generates more CO2, which lowers its pH and that induces more O2 unloading bisphosphoglycerate (BPG)-A metabolite in RBCs that binds to oxyhemoglobin and promotes O2 unloading

How do you get from DNA to protein? Help

borishaifa [10]

DNA is transcribed into RNA, 1 base of DNA corresponds to 1 base of RNA, this 1 to 1 relation is not used in the translation to protein. During this translation, 1 amino acid is added to the protein strand for every 3 bases in the RNA so before double stranded DNA is turned into protein it first goes through a process called transcription.

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.
