<u>Full question:</u>
Thousands of years ago, giraffes with short necks were common within giraffe populations. Nearly all giraffe populations today have long necks. This difference could be due to
giraffes stretching their necks to keep their heads out of reach of predators
giraffes stretching their necks so they could reach food higher in the trees
a mutation in genetic material controlling neck size occurring in some skin cells of a giraffe
a mutation in genetic material controlling neck size occurring in the reproductive cells of a giraffe
<u>Answer:</u>
This difference could be due to:a mutation in genetic material controlling neck size occurring in the reproductive cells of a giraffe
<u>Explanation:</u>
The primary short-necked forms contained large, mutable populations. Following the selection pressure of desiccations and leaf deficiencies, those changes with longer necks and forelegs sustained and repeated preferentially. In this procedure, throughout generations, these large mammals have occurred, being acclimated to their unique environment .
Lamarckian theory illustrated giraffe neck metamorphosis by showing that consistent stretching gradually extended their necks, and that they then moved on these propitious longer necks to their offspring. Environment and other variations created the extirpation of the eurasian giraffids, but various African species endured.
Answer:
The muscular dystrophy may be defined as the medical condition that leads to the weakening of the muscle and reduction in the muscle weight and loss of motor control.
The muscular dystrophy is the autosomal recessive disease. THis occur due to the mutation in the amino acids and arginine is replaced with histidine. The arginine pKa value is high whereas histidine pKa value is nearly upto 6-7. This disrupt the physiology of the proteins, disrupt its structure and result in the formation of misleading protein.
Answer:
C
Helicase enzyme
Explanation:
The main function of helicase is to basically unzip the DNA so that each strand can be copied
