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.

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 reverses the order of bases in a DNA strand. when the total number of bases in a DNA sequence remain the same. Replaces a base with its complementary base and produces a codon which codes for the same amino acid as the original codon.

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.

Please put in order for a food chain.

Answers

Answer: C) The benthic invertebrates would decrease in population size because they are eaten by the sea ducks and the phytoplankton would increase in population size.

Explanation:

The benthic invertebrates are eaten by sea ducks. Sea ducks are eaten by bald eagles. If the bald eagle was removed, there would be more sea ducks because they will have no more predators. Since there are more sea ducks, they will need to eat more food, like benthic invertebrates. The benthic invertebrates would have a lower population because the sea ducks eat more of them.

Why not the other answers:

A) The bivalves would not increase in population size. Without the bald eagle preying on sea ducks, there would be more sea ducks, who need to eat more food, such as eating more bivalves.

The phytoplankton would not decrease. With sea ducks eating more food, more benthic invertebrates are eaten. There would be less benthic invertebrates to eat phytoplankton.

B) Tundra swans were never eaten by bald eagles. There is no arrow connecting them.

D) Wading birds were never eaten by ospreys. There is no arrow connecting them.

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 sedimentaryform 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.

Ocean Acidification Evidence

Ocean Warming Evidence

:: expansion of ocean volume

:: difficult for some species to make shells

:: larger concentration carbonic acid

:: melting of glaciers and ice caps

growing difficulty in absorbing carbon dioxide

:: organisms more prone to illness

Answers

Answer:Ocean Acidification Evidence: Difficult for some species to make shells , larger concentration, organisms prone to illness . Ocean warming evidence: Melting of glaciers, expansion of ocean volume, growing difficulty in absorbing

Explanation:

Ocean Acidification Evidence includes difficult for some species to make shells , larger concentration, organisms prone to illness. Ocean warming evidence encompasses melting of glaciers, expansion of ocean volume, growing difficulty in absorbing.

What is ocean acidification?

The massive amount of carbon dioxide absorbed by the ocean dissolves as carbonic acid in seawater.

This is known as ocean acidification, and it is literally causing a sea change that is threatening the basic chemical balance of ocean and coastal waters from pole to pole.

As greenhouse gases trap more solar energy, the oceans absorb more heat, resulting in higher sea surface temperatures and rising sea level.

Ocean acidification is the decrease in pH of ocean water caused by CO2 dissolution in water.

Ocean warming, on the other hand, is the long-term gradual increase in the average temperature of the Earth's atmosphere. Ocean acidification and global warming are both negative consequences of human activity.

Acidification of the Oceans Evidence: It is difficult for some species to make shells, there is a higher concentration, and organisms are prone to illness.

Melting glaciers, increased ocean volume, and increasing difficulty absorbing are all signs of ocean warming.

Thus, this is the match for the given scenario.

HELPPPPP Some factories that burn coal produce smoke with harmful chemicals, such as sulfur. Scrubbers are devices that are attached to the smokestacks to reduce the amount of sulfur put into the atmosphere. To evaluate the effectiveness of these devices, what data would need to be collected?

A. The percentage of sulfur contained, on average, in a certain amount of coal

B. The amount of coal a factory burns each year, and how much sulfur it emits

C. The increase, over time, in the use of scrubbers by factories that burn coal

D. The amount of sulfur emitted by a smokestack before and after the scrubber is attached

Answers

Answer:

D. The amount of sulfur emitted by a smokestack before and after the scrubber is attached

To evaluate the effectiveness of these devices, the data would need to be collected is the amount of sulfur emitted by a smokestack before and after the scrubber is attached. The correct option is D.

What are scrubbers?

Scrubbers are devices for reducing air pollution that employ liquid to filter out gases or particles from an industrial exhaust or flue gas stream. To effectively remove particles and polluting gases from the gas flow, this atomized liquid (usually water) entrains them.

Wet scrubbers are tools that use direct contact with a liquid spray to capture suspended particles. As the many small droplets in the spray collide with and entrain the particulates, a scrubber effectively washes the contaminants out of the contaminated air stream.

Therefore, the correct option is D.The amount of sulfur emitted by a smokestack before and after the scrubber is attached.

2. Which of the following describes a negative feedback system?
running cattle increase panic within a herd
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
