In scientific evidence, "repeatable" refers to the ability of an experiment or study to produce consistent results when conducted multiple times under the same conditions by the same researchers. This reliability is crucial for validating findings and ensuring they are not due to random chance or specific circumstances. Repeatability is a key aspect of the scientific method, as it strengthens the trustworthiness of conclusions drawn from experimental data.

This condition is known as myopia, or nearsightedness, where the eye focuses images in front of the retina rather than directly on it. People with myopia can see nearby objects clearly, but distant objects appear blurry. It often occurs due to the shape of the eyeball or the curvature of the cornea. Myopia can be corrected with glasses, contact lenses, or refractive surgery.

Implied main ideas are not directly stated but can be inferred from the details and supporting information in a text. They require the reader to analyze the content and draw conclusions based on the context. Identifying an implied main idea often involves recognizing patterns, themes, or messages that the author conveys indirectly. This skill is crucial for deeper comprehension and critical thinking when engaging with various texts.

Zebra mussels are considered an invasive species because they are non-native organisms that have been introduced to new ecosystems, primarily through ballast water from ships. Once established, they reproduce rapidly and outcompete local species for resources, disrupting food webs and altering habitats. Their presence can also cause significant economic damage by clogging water intake systems and affecting industries such as fishing and tourism. This combination of ecological disruption and economic impact underscores their classification as an invasive species.

While on the island of St. Helena, Edmond Halley observed a new constellation that he named "Crux," or the Southern Cross. This constellation is notable for its distinctive cross-shaped pattern and is now recognized as one of the most prominent features of the southern sky.
