Astronomy (from Greek: ἀστρονομία, literally meaning the science that studies the laws of the stars) is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole.[1]
Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professional astronomy is often said to be the same as astrophysics.[2]
Professional astronomy is split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects. This data is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. These two fields complement each other. Theoretical astronomy seeks to explain observational results and observations are used to confirm theoretical results.
Astronomy is one of the few sciences in which amateurs play an active role. This is especially true for the discovery and observation of transient events. Amateur astronomers have helped with many important discoveries, such as finding new comets.
Explanation:
in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly. this phenomenon occurs because the rods located in the retina are:
In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark than cones.
The retina extends through the posterior portion of the eyeball is the innermost layer and in it are the photoreceptors: cones and rods.
Rods and cones are the two types of photoreceptor cells in vertebrates that capture light energy (photons) and convert it into electrical signals.
The rods are sensitive to changes in light, since their detection thresholds are low, so they only come into operation when the light intensity is low (scotopic vision or night vision).Scotopic vision has relatively low acuity, as the details of an object cannot be discerned or its color appreciated.On the contrary, cones have a much higher threshold for light, they are responsible for daytime vision (photopic vision) and their mission is to detect colors and shapes (details).Therefore, we can conclude that in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark.

What are some geological characteristics of glaciers in Glacier National Park?
Answer:
The minimum size criterion for a glacier is 0 .1 km², or about 25 acres. Below this size, the accumulated ice generally does not move and is stagnant. Many years of snow accumulation compacts the bottom layers of snow into ice. Under the huge weight of the snowpack (usually 100ft/30.5m thick or more), the ice becomes viscous and allows the mass to slide downhill. The appearance of crevasses and cracks attest to a glacier’s movement. Glaciers don't "bulldoze" landscape as much as they melt and re-freeze, plucking material from areas of snow deposition and moving it to other areas, like downhill conveyor belts.

after death, the cornea absorbs fluid and becomes opaque. in a living person, the cornea is translucent due to _______________.
Given what we know about human anatomy, we can confirm that the cornea of a live human is translucent due to the arrangement of its collagen fibers and the lack of vascularity.
One important factor in the translucent nature of the cornea and lens is its lack of vascularity. This area of the eye has few if any vascular components, which contributes to its lack of pigment.
However, the main component that contributes to the translucent nature of the human cornea is its very specific arrangement of collagen fibers.
The bundled nature of these fibers, together with the water content of the cornea, allow it to remain translucent.

What does it mean when we say that replication is a Semi-Conservative process?
Answer:
Semiconservative replication describes the mechanism of DNA replication in all known cells. ... This process is known as semi-conservative replication because two copies of the original DNA molecule are produced, each copy conserving (replicating) the information from one half of the original DNA molecule.

Evaluate the procedure used in this experiment by considering the properties used to identify the unknowns and the number of knowns that were tested. Revise the experimental design by proposing ways to modify the experiment to increase your certainty in the identity of the unknowns
Answer: Hey! its a fellow classmate from K-12! Alright so what I put for the lab report question is : The properties used to identify the metals were mass, length, and volume. These were the extensive properties that I used. I would propose to test color, malleability, melting points, and to test how shiny or dull it is. I would propose these to increase the certainty in the identity of the metals. Btw, please mark me brainliest.
Explanation: When it says evaluate It pretty much means " tell me what you used to figure out the identity of the unknown metals".
The part where it says " propose, revise...blah...blah blah means " How could you increase your chance to get the right metal identity, henceforth saying what properties and tools could we use to make this experiment more better; better chances of getting the right identity of metal.
