Which structure is responsible for the passage of materials into and out of the cell?
Answers
Answer:
A
Explanation:
It is the cell membrane
The plasma membrane is a boundary of cell responsible for the movement of any substance in and out of the cell, hence a is the correct option.
What is a cell membrane?All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. The cell membrane controls the flow of substances into and out of the cell.
Watery fluid surrounds and fills cells, this liquid facilitates the movement of substances across the cell membrane as well as within and outside the cell.
Some solutes (solids) can pass through cell membranes depending on their nature.
Therefore cell membrane allows the substance to pass into cell and out of the cell, hence option a is correct.

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.
Answers
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.

microphone speaker feedback
feedback that magnifies output
feedback that regulates and stabilizes
Answers
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

Explain in detail how CONVECTION heat transfer effects our weather?
Answers
Answer:
The sun's waves heat the ground, causing it to warm (radiation). The energy flows from the warmer ground to the cooler air (conduction), causing it to rise (convection). When the rising air reaches a certain point, it expands, cools, and the cooler expanded air can no longer hold as much water vapor so it rains.
Explanation:
Answer:
convection occurs over a very very long time in the earth's mantle. Rock slowly gets melted down from the core, then shoots back up from volcanoes. The new rocks get buried by sand and sediments, and the process resets.

A Carbon Sink is a reservoir which absorbs more carbon than it releases. Suggest how carbon in the bodies of crustaceans and molluscs is removed from the oceanic food chain to become part of another, slower carbon reservoir.
Answers
Answer:
Crustaceans and Molluscs play an important role in the oceanic carbon sink.
Explanation:
Carbon sinks can serve to partially offset greenhouse gas emissions. Forests and oceans are both large carbon sinks. Algae is pressurized to bottom of the ocean by long term sequestration. Algae then falls to the bottom of the ocean and TRANSFORMS to fossil fuels.
CO2 is not combustible. creates carbonic acid in the oceans. Reduces seawater pH, carbonate ion concentration, and thus calcium carbonate (needed for shells for marine creatures, contributes to BOTTOM-UP EFFECT)If helpful, please mark as brainliest! =)

A mutation is least likely to affect a cell when the mutation --
Answers
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.

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?
Answers
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.
