Answer: To attract a Mate
Explanation: In competition, males use feather color to warn potential rivals that they occupy a piece of territory. When it's time to mate, male birds show off their plumage to attract a mate. In experiments, female birds prefer males with more fanciful feathers, or brighter colors.

What is the purpose of protein synthesis?
Answer:
Protein synthesis is the process all cells use to make proteins, which are responsible for all cell structure and function. There are two main steps to protein synthesis. In transcription, DNA is copied to mRNA, which is used as a template for the instructions to make protein.
Explanation:
Proteins are one of the most important biomolecules essential for the survival of organisms owing to the myriad of functions that they play in the physiological system.
Proteins that are ingested are easily degraded to amino acids or peptides by the action of HCl in stomach and the digestive enzymes present in the gastrointestinal tract. Thus, proteins have to be synthesized in the body to meet the body's needs for various functions.
Some of the functions of proteins include:
1. Enzymes are majorly proteinaceous in nature and are required for crucial functions, including cell division and DNA synthesis.
2. Motor proteins help in movement and also provide cytoskeletal structure to the body.
3. They are required for the functioning of the immune system.
4. Proteins are required for cell signaling pathways.

Answer:
The correct answer would be - scientific theory.
Explanation:
A scientific theory is a confirmed explanation of any particular natural aspect or phenomenon of the world which is confirmed and accepted widely by the facts based on observation and experiment.
This particular idea or explanation for the natural phenomenon is true time based and believed to be true for time being and proved for a time but can be changed with the new discoveries and facts.

4. In this investigation oxygen production was used to measure the light reaction. What are
two additional products that could be measured? What purpose do they serve in the light-
independent (dark) reaction?
Answer:
Photosynthesis is the process by which green plants absorb light energy from the sun with the assistance of water and carbon dioxide, and transform it into chemical energy to make (synthesize) carbohydrate (specifically glucose) and oxygen.
The "light-independent" or dark reactions happen in the stroma of the chloroplasts. This is also known as the Calvin Cycle. Since these processes can only happen in the chloroplast (a chlorophyll filled plastid in green plants), photosynthesis can only happen in green plants!
The first overall principle of photosynthesis is that the light energy from the sun is transformed into chemical energy and stored in the bonds of glucose (the sugar carbohydrate) for later use by the plant and/or organism that eats the plant.
The second overall principle of photosynthesis is that carbon, oxygen, and hydrogen atoms are taken from carbon dioxide and water molecules and are broken up and rearranged into new substances: carbohydrate (specifically glucose) and oxygen gas (so we can breathe, whew!). This reaction represents the transfer of matter: carbon dioxide from the atmosphere, water from the soil or atmosphere, into sugar in the plant and oxygen back into the atmosphere.
Light-Dependent Reactions
The first part of the process happens in the thylakoids of the chloroplasts and are the "light-dependent" reactions: The photosystems I and II absorb the photons from the sunlight and process them through the membranes of the thylakoids simultaneously. The photons excite electrons in the chlorphyll which then move through the electron transport chain and causes NADP- to combine with H+ forming NADPH. At the same time, ADP (adenosine diphosphate) has come from the dark reaction and a third phosphate chain is bonded forming ATP (adenosine triphosphate) to feed the Calvin Cycle next. Remember that ATP is the important source of all cellular energy.
We now believe that all the oxygen released in photosynthesis comes from the water molecules and all oxygen atoms that form the carbohydrates come from the carbon dioxide molecules. So, in other words during the light-dependent reaction a water molecule is broken down producing two H+ ions and half an oxygen molecule. We get the rest of the oxygen molecule when another water molecule is broken down.
Dark Reactions
Dark reactions are also known as the Calvin Cycle, the Calvin-Benson cycle, and light-independent reactions. The point is that they do not require sunlight to complete their process.
After ATP is formed in the first part of photosynthesis, for living things to grow, reproduce and repair themselves, the inorganic form of CO2 must be transformed into carbohydrate. This happens during the Calvin Cycle in the stroma (the fluid filled interior of the chloroplast). ATP and NADPH combine with CO2 and water to make the end product of glucose. The ADP and NADPH+ are recycled to the light-dependent side to start the process over.
Remember that during hours of darkness, plants cannot perform photosynthesis so they do cellular respiration in the mitochondria just as all living organisms do.

Raj made the timeline below to show the progression of thinkers who developed theories about Earth's place in the universe. ? À Copernicus à Galileo à Newton Which thinker belongs at the beginning of Raj's timeline? Aristotle Kepler Ptolemy Thales
Answer:
Ptolemy
Explanation:
Ptolemy is the earliest earliest astronomer and mathematician in the list who lived and worked in the second century AD. Nothing is known about his personal life but his scientific work is well known.
He made his observations using naked eyes. In his opinion, the Universe is ''a set of nested, transparent spheres, with Earth in the center.''(Khan Academy). His argument was that the Moon, Mercury, Venus, and the Sun were all revolving around around Earth.
Although Ptolemy made significant contributions in Astronomy but he was wrong in positing that the earth did not move at all. This is inconsistent with our present day knowledge about the celestial bodies. Also, his work missed out other planets that were yet to be discovered then such as Uranus, Neptune, Pluto etc.

Your friend Olivia has a blemish on her shoulder that she can't easily see herself, so she asks you to check it out for her to help her decide if she should see her doctor. What are at least three things you would look for to help you advise her? (Remember: ABCDE!)
Answer:
Explanation:
There are a couple of things you can look for when analyzing your friend's blemish to determine whether she should see a doctor or not. Three of these signs are
Discoloration or texture on the blemish.The blemish is itchy or irritated.The blemish is bleeding
All three of these are signs that Olivia should see a doctor/dermatologist as soon as she can. This is because all of these point to skin cancer. A regular blemish is a single color and is imbedded within the skin. It does not appear textured or out of the skin, or even two or three different colors. Blemishes also are not itchy or bleed. Therefore, any of these signs would be a cause for concern.

Explanation:
A city is located in an area that has experienced 7.5-magnitude earthquakes in the past. The city is considering building a new skyscraper.
Use the earthquake magnitude scale to predict the amount and type of damage residents should expect from future earthquakes of similar magnitude. Then suggest a way to minimize the effects of future earthquakes on the skyscraper.
Answer:
The residents should expect collapsing parts of the building, or even the building itself would collapse if the building cannot hold/not sturdy enough for earthquakes ranging around 7.0m to 7.9m. If the building is built by hills or rocky land, expect landslides to be happening. A way effects of future earthquakes can be minimized is that the building should be constructed with sturdy material (such as steel) so that it can withstand most of the force of a 7.0-7.9m earthquake.
