A is the correct answer for that question
Explanation:
Examples of a Hypothesis Not Written in a Testable Form
"It doesn't matter" doesn't have any specific meaning, so it can't be tested. Ultraviolet light could cause cancer. The word "could" makes a hypothesis extremely difficult to test because it is very vague.
Answer:
Huntington's disease. (Ans. A)
Explanation:
Huntington's disease: It is known as the inherited disorder (degenerative) which cause the breakdown of the central nervous system.
Huntington's disease mainly causes functional abilities, and result in movements (such as slow eye movement, muscle problem like dystonia and rigidity), psychiatric (such as insomnia, feeling of sadness and loss of energy), and cognitive disorder (such as lack of action, and flexibility, slowness on finding words, etc.)
Mid ocean ridges which contribute to the process of seafloor spreading Form as a result of two tectonic plates moving apart (or diverge). As the plates move apart, a crack is formed in the rock between the plates.
Magma rises from beneath and flows up through the crack and spreads out over the crack where it cools as it meets the sea water and solidifies adding to the edges of the sideways moving plates.
A long chain of mountains called an oceanic ridge is formed as magma continues to pile up along the crack.

The other strand is oriented in the 5’ to 3’ direction (away from the replication fork), this is the <span>lagging strand?</span>. As a result of their different orientations, the two strands are replicated differently:</span></span>
