The answer is B)<span> </span>temporal isolation.
<span>
<span>Temporal isolation is a type of reproductive isolation, which could be prezygotic or postzygotic. Temporal isolation is prezygotic reproductive isolation since it occurs before fertilization and zygote production. Temporal isolation is result of temporal differences in breeding. In this example, the breeding season of Rana aurora lasts from January to March while the breeding season of Rana boylii lasts from April to July. So, these two breeding seasons do not coincide and these species could not mate.</span></span>

Explanation:
They first 'cut out' genes using precise biological 'scissors' – restriction enzymes – and paste them into DNA from another organism like a bacterium or yeast where it is copied many thousands or millions of times. Molecular model of a restriction enzyme bound to DNA.
<span>The answer is anulus fibrosus.
</span>
The intervertebral disk is located between vertebrae. It is has two parts, the middle part which is called nucleus polposus and the outer part, the <span>Anulus Fibrosus. This outer part, </span>is a strong fibrous tissue in the form of a ring, that can withstand compressive forces.
Plants that have TUBELIKE<span> STRUCTURES that carry water, nutrients, and other substances throughout the plant have </span>xylem<span> and </span>phloem<span> true roots stems and leaves. Absorbs water and minerals from the ground. Anchors plant in ground. Waxy, protective layer that covers the leaves, Helps prevent water loss.</span>
