Answer:

Coral reef fish are a significant food source for over a billion people worldwide. Many coastal and island communities depend on coral reef fisheries for their economic, social, and cultural benefits. But too much of a good thing can be bad for coral reefs. Download this infographic | Infographic Text

Coral reef ecosystems support important commercial, recreational, and subsistence fishery resources in the U.S and its territories. Fishing also plays a central social and cultural role in many island and coastal communities, where it is often a critical source of food and income.

The impacts from unsustainable fishing on coral reef areas can lead to the depletion of key reef species in many locations. Such losses often have a ripple effect, not just on the coral reef ecosystems themselves, but also on the local economies that depend on them. Additionally, certain types of fishing gear can inflict serious physical damage to coral reefs, seagrass beds, and other important marine habitats.

Coral reef fisheries, though often relatively small in scale, may have disproportionately large impacts on the ecosystem if conducted unsustainably. Rapid human population growth, increased demand, use of more efficient fishery technologies, and inadequate management and enforcement have led to the depletion of key reef species and habitat damage in many locations.

Answer:

If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst. A hypertonic solution means the environment outside of the cell has more dissolved material than inside of the cell. If a cell is placed in a hypertonic solution, water will leave the cell.

Answer:

A. Mid ocean ridge

Explanation:

A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.

The mid-ocean ridge, rift valley is a geological feature can be created by a divergent boundary. Therefore option A is correct.

A divergent boundary is a type of tectonic plate boundary where two lithospheric plates move away from each other. This movement creates a gap or space between the plates, allowing magma from the asthenosphere (the partially molten layer of the Earth's mantle) to rise and fill the void.

As the magma reaches the surface, it cools and solidifies, forming new crust. This process occurs primarily in the oceanic lithosphere, resulting in the formation of mid-ocean ridges.

Mid-ocean ridges are underwater mountain ranges that run along the seafloor and span across the Earth's oceans.

The trait being described is the ability to fly in rainy season.

Explanation:

The trait being described is the ability to fly in rainy season. The people with bat wings and people with bird wings are present in the population. The event lead to the change in allele frequency because the population of people with bird wings die due to starvation. Yes, the bat wings were adapted to that environment so they are able to survive. The change make the population less similar to other populations because population of people with bat wings increases as compared to other population. Yes, the new population change for the better of the ecosystem because the population is able to controls the population of other species in the ecosystem.

Answer:

The correct answer is - these resources take million years to be replenished.

Explanation:

Non-renewable resources are the resources that come from a source that will finish ultimately or run out or can not be replenished in one or more human life cycles. These sources might take million years to replenish.

Most non-renewable resources are fossil fuels, coal, natural gas. Fossil fuels, cols are were formed as the remains of dead plants and animals but takes millions of years to decay, under huge amounts of pressure and heat.

Answer:

The sperm cells.

Explanation:

Liver cells, sperm cells and unicellular organisms all undergo meiosis. Therefore, the correct option is D.

A specific cell division known as meiosis occurs in sexually reproducing organisms. The cells produce gametes through this process, which are the specialized sex cells used in sexual reproduction. Despite not being directly involved in reproduction, liver cells can undergo meiosis. Under certain circumstances, meiosis in liver cells can be induced to form haploid cells.

Male gametes, or sperm cells, undergo meiosis as part of spermatogenesis. Haploid sperm cells with half the number of chromosomes than the parent cell are formed during meiosis in the testis. Depending on their reproductive strategies, unicellular organisms may also undergo meiosis to produce haploid cells that can mate with other haploid cells during sexual reproduction.

Therefore, the correct option is D.

Mutations are essential for evolution to occur because they produce variations within a population.

Explanation:

This is because Mutation refer to change in the genetic content or DNA composition of organisms. Therefore , for evolution to occur there must be Mutation because it is the main source of genetic variation or causes genetic variation needed for evolution.

Mutation is important as the basics of evolution because it produce a new DNA sequence for a gene function, which lead to the formation of new allele.

statements describe aspects of what causes wind to blow is Wind is caused by differences in air pressure. Explanation: Due to different rate of heating and cooling of air there is difference of the air pressure on the surface of the land.Apr 10, 2020

Answer:

The Correct Answer is A and C.

Explanation:

The wind is the movement of air, the movement of air is happened by the difference in pressure.

A difference in air pressure is what causes the wind to blow. Difference in pressure is happened by the uneven heating of the earth's surface.

The wind is normally moving air from a high air pressure place to a low air pressure place.

The greater the difference in air pressure the stronger the wind blow.
