Answer:
Rocks across the ocean floor have alternating magnetic stripes.
Explanation:
Different types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. This evidence made scientists take a second look at Wegener's hypothesis of continental drift.
Answer:
A
Explanation:
Small sacs of fluid called bursae cushion the Achilles tendon at the heel. The Achilles tendon is the largest and strongest tendon in the body. When the calf muscles flex, the Achilles tendon pulls on the heel.
Answer:
The changes in the sequence of nucleotides present within a promoter is a prime cause of the defected transcriptional regulation, which may eventually result in disease. However, not every modification within the sequence of a promoter influences the regulation of transcription, it relies upon the nature and the location of the genetic defect.
When a mutation results within the sequence of a promoter region it may hamper the usual procedures of gene stimulation by affecting the step by step alignment of the transcription factors at the promoter region. Therefore, as a consequence, a mutation within the sequence of a promoter may result in the enhancement or reduction in the level of mRNA and thus protein.
The answer that best fits the blank is RENDERS CILIA IMMOBILE. What happens when the left-right asymmetries in humans are reversed would lead to a genetic condition that renders cilia immobile. This is based on the role of the ciliated cells in the body that has an important impact in one's biological development.
