Access to cities is not a key factor important to the development of human society, but clean water, fertile soil, and Access to natural resources all are needed, hence option C is correct.
What are factors important to the development of human society?The preagricultural (hunting and gathering) stage, the agricultural stage, and the industrial stage are thus the at least three primary stages of societal evolution or civilizations.
Clean water is essential to our way of life because it creates a habitat for species and places to fish, paddle, surf, and swim. Our economy is reliant on clean water to operate and thrive. This includes industries like manufacturing, agriculture, tourism, recreation, and energy generation.
They support tax revenue, income, and the fight against poverty. Natural resource-related industries generate employment and frequently form the backbone of poorer towns' economies.
Therefore, natural resources are fundamentally important, so they must be managed responsibly.

Usable fresh surface water is relatively scarce. To many people, streams and lakes are the most visible part of the water cycle. Not only do they supply the human population, animals, and plants with the freshwater they need to survive, but they are great places for people to have fun.
Answer:
True.
Explanation:
Usable fresh surface water is scarce. Freshwater is not in excess on our planet. We can find it on lakes, lagoons, rivers, and swamps, but it is only 3% of the totality of Earth's water. The importance of this water is that it is the one that is suitable for humans, a large number of plants, and animals. This is why there are different methods to store and distribute fresh water amongst all the population and places that need it. Besides, the places where freshwater is, are great for activities, such as swimming, sailing, rafting, diving, fishing, etc.
Since freshwater is scarce and has so many uses, we must take care of it.

Who does not need a circulatory system?A single-celled organism that doesn't required the circulatory system as human do. Since they are the singular, they can interact with their environment directly. Oxygen need to be supplied by the circulatory system and some of the cells also well differentiated so it can be only accept a certain processed food.
Most mollusks, or except for the some particular cephalopos like skids, have an open circulatory system in which the circulating fluid has been called hemolymph that flows through the body thanks to the muscle contractions that pump this fluid into the hemolymph vessel that discharges this fluid into the body cavity allowing substances and gases to be exchanges between body cells and the carrying hemolymph. Then this fluid goes back to the blood vessel and reinitiates the circulation.
Therefore, Thus, option C is correct.

The diagram above shows how sea breezes form clouds in coastal areas. Which map below shows a cloud pattern that would most likely result from the sea breeze cycle in late afternoon?
Answer: Map H
Explanation:
Sea breeze cycle clouds form in an area where land and a body of water such as an ocean or sea come into contact with each other so maps G and J are not possible as these formed over land and away from any coastlines.
These clouds form over land as it is on land that the sea breeze would be warmed by the land temperature and then rise up. Map F is therefore incorrect as those clouds are over the sea.
Map H is the most plausible answer as the clouds are right over land and the area is next to the ocean.

The correct statement is B) Part 1 are consumers, Part 2 are producers.
What are the two parts of food chain?Part 1 of the food chain describes organisms that are the end of the food chain, which would typically be consumers or animals that feed on other organisms, including plants and other animals.
Part 2 of the food chain refers to something that passes energy to plants and animals. This is typically the sun, which provides energy through photosynthesis to producers, or plants, that convert light energy into chemical energy stored in food. Producers form the base of the food chain, providing energy to all other organisms in the ecosystem through the food they produce.

A mutation is least likely to affect a cell when the mutation --
A mutation is least likely to affect a cell when the mutation is silent in nature or is not associated with an exon, it is least likely to affect a cell. Any mutation that happens to the introns does not affect the cell's function.
What is the function of cells and mutation?As genetic materials, nucleic acids encode information about the cell's structure and function, its proteins, receptors, and so on. The mRNA that is formed from the gene has roles in the formation of the receptor, the enzymes, etc., so if any mutation happens to the gene that is in the coding region, then it can show its impact, but if the mutation is of the silent type, then it has no impact on the cell.
Hence, when a mutation is silent in nature or is not associated with an exon, it is least likely to affect a cell. Any mutation that happens to the introns does not affect the cell's function.

running cattle increase panic within a herd
microphone speaker feedback
feedback that magnifies output
feedback that regulates and stabilizes
Answer:
Feedback that regulates and stabilizes
Explanation:
Negative feedback systems are ones that try to always maintain homeostasis, or a certain state.
For example, the regulation of body temperature in humans is a negative feedback loop. This is because the body maintains a constant temperature at homeostasis, and will adjust if it is too hot or cold.
Feedback that regulates and stabilizes is a negative feedback system, because it involves regulation/stabilization, similar to the regulation of body temperature.
So, the correct answer is Feedback that regulates and stabilizes
Answer:

The Rock Cycle is happening all the time on Earth.
Some processes of the Rock Cycle take a long time.
O All rocks were once Metamorphic Rocks.
O Most rocks on Earth are Igneous Rocks.
Answer:All rock were once metamorphic rocks
Explanation:
Melted rock deep inside Earth forms igneous rocks. Sand, silt, plant and animal skeletons make sedimentary rocks. Heat and pressure underground convert rocks into metamorphic rocks. Therefore, option (C) is correct.
What is rock cycle?The rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the various applications of heat and pressure over the course of time. Igneous rocks are rocks that are formed by volcanic eruptions, while metamorphic rocks are formed when heat and pressure are applied to preexisting rocks. Shale, a type of sedimentary rock, can be transformed into slate with the use of heat and pressure, for instance.
The rock cycle is an important component of our dynamic Earth because it allows rocks to shift from one type of rock to another based on their location and circumstances. It recycles rocks to build new structures when plate tectonics changes the Earth's surface.
