Answers
A lunchroom worker might conclude that the majority of students would prefer to have either nachos or mystery meat. Thus, option C is correct.
What is food waste?
The food is important for the animals as well as plants and other living individuals as it gives them energy when cells use the food in cellular respiration, and based upon the energy most of the work is done, such as body repair, cell division, growth, etc. As the population grows, the rate of food cultivation cannot keep up to feed everyone, so food waste must be avoided so that everyone gets the required amount of food.
In an attempt to save money, the lunchroom staff sent out student questionnaires to see which foods students preferred, and it was found that pizza was the favorite food of about one-third of the students.
Therefore, A lunchroom worker might conclude that the majority of students would prefer to have either nachos or mystery meat. Thus, option C is correct.

What best describes ribosomes?
Answers
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein

Please someone answer I need help.
Answers
Answer: The Low Pressure systems will usually be found more North where it gets verycold but can really happen anywhere, and High pressure systems are usually found in the Southwest during winter.
Explanation:
High Pressure:A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator. This is called anticyclonic flow. Air from higher in the atmosphere sinks down to fill the space left as air is blown outward. On a weather map, you may notice a blue H, denoting the location of a high pressure system.
Low Pressure:
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation. Because of Earth’s spin and the Coriolis effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the equator. This is called cyclonic flow. On weather maps, a low pressure system is labeled with red L.

This type of volcanism, hot spot volcanism, is unique. Why?

Label the Big Dipper, Little Dipper, and indicate the Polaris.
Answers
The Polaris lies in a direct line with the Earth's rotational axis, which is "above" the North Pole (north celestial pole). Its stands almost motionless in the sky, and all the stars of the northern sky appear to rotate around it. The attached image is a clear indication.
How can we describe the Polaris location in the sky?The Polaris appears to remain stationary in the sky while all other stars appear to rotate around it. To locate Polaris in the sky, one must first find the Big Dipper, which is a well-known group of seven stars that resemble a ladle or dipper. If one follows the two stars at the end of the bowl of the Big Dipper, they will point directly to Polaris.
Once located, Polaris can be used as a guide to determine one's direction when navigating at night. Because it is very close to the celestial north pole, its position in the sky is directly above the Earth's geographic North Pole. This makes it a reliable reference point for navigation in the Northern Hemisphere.

The thing is I can't find out which hormone the hypothalamus produces that sends signals to the pineal gland to produce melatonin. any help would be massively appreciated
Answers
Here is a possible chat between the hypothalamus and the pineal gland before sleep:
Hypothalamus: Hey pineal gland, it's getting dark outside. Time to start producing melatonin.Pineal gland: Sure thing, hypothalamus. I'll get right on it.Hypothalamus: Thanks, pineal gland. I'm going to go take a nap now.Pineal gland: Good night, hypothalamus. Sleep well.How does the endocrine system work for sleep?The hormone that the hypothalamus produces that sends signals to the pineal gland to produce melatonin is called melatonin-releasing hormone (MSH). The hypothalamus and the pineal gland work together to regulate sleep-wake cycle.
When it gets dark outside, the hypothalamus releases MSH, which signals the pineal gland to start producing melatonin. Melatonin is a hormone that makes the body feel sleepy. It helps to regulate the body's internal clock and to promote sleep.

Research how coral reefs are formed. What types of animals live there? What important roles do cnidarians play in coral reefs? How do the tiny animals get their food? How do algae help the corals? Write three paragraphs describing coral reefs. Include the information listed above plus any other information you find.
Answers
Fish, corals, lobsters, clams, seahorses, sponges, and sea turtles are only a few of the thousands of creatures that rely on reefs for their survival.
Cnidaria have important ecological roles as reef structure builders, and as predators and prey in planktonic and benthic ecosystems.
At night, coral polyps come out of their skeletons to feed, stretching their long, stinging tentacles to capture critters that are floating by. Prey are pulled into the polyps' mouths and digested in their stomachs.
Algae belonging to the group known as dinoflagellates live inside the corals' tissues. The algae use photosynthesis to produce nutrients, many of which they pass to the corals' cells. The corals in turn emit waste products in the form of ammonium, which the algae consume as a nutrient.
Coral reefs begin to form when free-swimming coral larvae attach to submerged rocks or other hard surfaces along the edges of islands or continents. As the corals grow and expand, reefs take on one of three major characteristic structures — fringing, barrier or atoll.

A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate.[1] Most coral reefs are built from stony corals, whose polyps cluster in groups.
Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian.[2]
Sometimes called rainforests of the sea,[3] shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species,[4][5][6][7] including fish, mollusks, worms, crustaceans, echinoderms, sponges, tunicates and other cnidarians.[8] Coral reefs flourish in ocean waters that provide few nutrients. They are most commonly found at shallow depths in tropical waters, but deep water and cold water coral reefs exist on smaller scales in other areas.
Coral reefs have declined by 50% since 1950, partly because they are sensitive to water conditions.[9] They are under threat from excess nutrients (nitrogen and phosphorus), rising ocean heat content and acidification, overfishing (e.g., from blast fishing, cyanide fishing, spearfishing on scuba), sunscreen use,[10] and harmful land-use practices, including runoff and seeps (e.g., from injection wells and cesspools).[11][12][13]
Coral reefs deliver ecosystem services for tourism, fisheries and shoreline protection. The annual global economic value of coral reefs has been estimated at anywhere from US$30–375 billion (1997 and 2003 estimates)[14][15] to US$2.7 trillion (a 2020 estimate)[16] to US$9.9 trillion (a 2014 estimate).[17]
