Layers of fossils in pillars, the rock covering them is dated and we get an exact time of each layer.
Answer:
only females
Explanation:
In humans, sex chromosomes in males and females are different. The sex chromosomes found in humans are X and Y chromosomes. X-linked trait is a trait which is inherited on the X- chromosome. According to the question, the trait is passed on a X-linked dominant condition, which means the condition is inherited on the abnormal dominant X-chromosome that will express itself even when in an heterozygous state with a normal X-chromosome.
Hence, a father affected by the condition will have a genotype; XY while a mother that does not have the condition will have a genotype: xx (two normal x chromosomes). Since the Father can only pass his X chromosome to his daughters and never his sons, all his daughters will inherit the condition (see the punnet square in attached image).
N.B: None of the sons will inherit the condition since the mother will pass normal X-chromosomes (x) to her sons.
For a nurse it is quite normal because she knows the pattern of breathing of a small baby but for a primipara ( a lady who is giving birth for the first time ) it might not be acceptable to understand the fact that a newly born baby has an irregular breathing pattern switching in between fast and slow .
As she is a new mother she might not be aware of the fact that a baby breathes very fastly to compensate the amount of energy required to maintain the homeostasis of the baby.As the baby is in growing stage the amount of energy required is much more as compared to that of adults.
Hence , the nurse will not take any medical action as the baby is not sick but yes she will definitely tell the mother that it is normal in baby
Answer: Spindle Formation
Explanation:Mitosis begins with prophase, during which chromosomes recruit condensin and begin to undergo a condensation process that will continue until metaphase. In most species, cohesin is largely removed from the arms of the sister chromatids during prophase, allowing the individual sister chromatids to be resolved. Cohesin is retained, however, at the most constricted part of the chromosome, the centromere (Figure 9). During prophase, the spindle also begins to form as the two pairs of centrioles move to opposite poles and microtubules begin to polymerize from the duplicated centrosomes.
