Why is it important to have a balance of predators and prey in an ecosystem?
2 Some scientists think that fishing should be "unselective". They suggest that fisheries should
catch fish of all species and sizes. Why do you think this might not be a good idea?
3 Looking at figures 2 & 3, which fishing strategy results in the lowest catch and biomass?
The most important economic factor for commercial fisheries is profitability - this is the
4
difference between the money that the fishermen can sell their catch for, and the cost of
fishing. Can you think of some of the costs of fishing, and why do you think that the rules in
our study will help to reduce these costs?
If the science is so clear about the economic benefits of sustainable fishing, why are fishers
5 not going for it? Why are they not willing to catch less for 2-3 years, to help the fish recover,
if thereafter they can catch substantially more forever? Why do you think are managers and
politicians not helping fishers to make the transition?

Answers

Answer 1

Answer:

To maintain equilibrium.

Explanation:

It is very important to have a balance of predators and prey in an ecosystem because the population of the species in that ecosystem is in equilibrium state. The fisheries should  catch fish of all species and sizes in order to maintain balance of predators and prey in that ecosystem. they are not willing to catch less fishes for 2-3 years, to help the fish recover because they want to make more profit from it.  The managers and  politicians do not helping fishers to make the transition because they have no profit in that transition so they showing no interest.

The core of a mountain range that formed during regional metamorphism would contain a _____ metamorphic facies.

Answers

Answer:

The answer is below

Explanation:

Most metamorphic rocks are formed from regional metamorphism. When two plates collide, it causes the release of large amount of pressure, this causes a deformation (folding and faulting) of the rock. As a result of the collision, the denser plate may be forced under the less dense plate thereby causing the rock to fall deep where they are subjected to high pressure and temperature.

Regional metamorphism produces green schist facies, amphibolite facies and granulite facies.

In which region of the United States is a hurricane likely to inflict the MOST amount of damage?

The Midwest
The Northeast
The Northwest
The Southeast
The Southwest

Answers

Answer:

The Southeast

Explanation:

The Southeast includes Florida, Louisiana, Alabama, Georgia, South and North Carolina, and east Texas. These are the most vlnerable states to Hurricane's therefor it can inflict the most damage in the Southeast.

Answer:

The Southeast is the region most likely to have the most damage from hurricanes.

Explanation:

The United States is one of the countries that suffer the most from hurricane activity, and when it comes to actual damage it is by far on top of any other country. Not all parts of the country experience hurricanes though, and the regions that do differ when it comes to the intensity and damage they experience.

ting The region that almost always has it the worst is the Southeast. The reason why this region of the United States has it the worst is because the hurricanes form in the Caribbean Sea and central-east Atlantic, and with the movement of air masses going directly toward this part of the United States it is obvious that it will be hit the hardest. The amount of damage by the hurricanes comes in numerous forms, varying from life loss, destruction of property, flooding, destruction of infrastructure, creating a humanitarian crisis, etc. The damages are often counted in billions of dollars.

c) The air above the sea is less dense and rising
d) The air above the land is less dense and rising

Answers

Answer:

The air above the sea is less dense and rising.

Explanation:

During the daytime, the sun warms up both the ocean exterior and the land. Water is a healthy absorber of rays from the sun. The land occupies much of the sun's heat properly. However, the water warms up much more gradually than land and so the air overhead the land will be more temperate relate to the air above the ocean.

can someone help me understand how to solve this problem?​

Answers

Answer:

x  = 35

Explanation:

To solve this problem, we are going to use the concept of angle on a straight line.

The sum of angle on a straight line is 180°; so if we add the two given angles together, we must arrive at this value.

  Given angles are:  (3x + 2)°  and (2x + 3)°

     3x + 2 + 2x + 3  = 180

             5x + 5  = 180

              5x  = 180-5

             5x  = 175

               x  = 35

Where would the stream flow fastest?
Between 1 and 2
Between 2 and 3
Between 3 and 4
Between 4 and 5

Answers

Answer:

The stream will flow fastest between 2 and 3.

Explanation:

On this map, we can see two basic elements, one being the contour lines, and the other being the color with which a stream is presented. The contour lines are giving us a good representation of the relief and where it is steeper and where it is less steep. Basically, where the contour lines are closer to each other, we have a steeper relief, and when the contour lines are further away, the relief is less steep.

The water moves under the influence of gravity, so downward. Where the steepness is the greatest, the gravity influences it the most, so it moves faster, while where the steepness is smaller, the gravity influences it less, so it moves slower. On this map, the contour lines are closest to each other between points 2 and 3, meaning it is the steepest part of the relief, and it is the place where the stream flows the fastest.

Describe the two basic types of igneous processes that may produce an ore deposit during the crystallization of magma, and provide examples of metals that may be concentrated by these processes.

Answers

Answer and Explanation:

Igneous rock is formed by a liquid rock when it freezes into solid rock. This molten material is in the ground is called magma, and when it is on the surface, it is called lava.

Magma Generation:

Magma and lava contain three components:

• melt

• solids

• volatiles

It is made of ions from minerals that have liquefied. Minerals floating in the liquid melt made crystallized minerals. These minerals may have already cooled Volatiles are gaseous components, for example, water vapour, carbon dioxide, sulfur, and chlorine—dissolved in the magma. The amount of these components affects the physical behaviour of the magma.

Bowen’s Reaction Series:

Bowen’s Reaction Series describes how the minerals crystallize when cooled, or melt when it is heated. The low end of the temperature scale where all minerals crystallize into solid rock is:

Approximately 700°C (158°F)

The upper end of the range where all minerals exist in a molten state is:

Approximately 1,250°C (2,282°F)

These two basic types of igneous processes produce an ore deposit during the crystallization of magma.

HURRY PLZ!!!!!!!! Describe the major differences between the two cultural groups that reside in Cyprus.

Answers

Answer:

The Republic of Cyprus is an island country in the Eastern Mediterranean Sea. It is relatively small, measuring 240km long and 100km wide at most. However, its strategic position between the Middle East and Eastern Europe means it has endured many different civilizational periods that inform its culture today. Cyprus has two very distinct ethno-religious communities – the Greek Cypriots and Turkish Cypriots – that share cultural affiliations with Greece and Turkey respectively. Since 1974, the country has been partitioned into two main parts on the basis of these ethnicities. The geography, culture, politics and daily life of Cyprus have become deeply characterised by the ‘Cyprus Problem’. As such, the island has a unique psyche. People tend to be very loyal to their ethnic communities. Nevertheless, Cypriots share strong values of hospitality and personal honour. The increasing globalisation of the island has seen the people become more urban, internationally focused, cosmopolitan and outward-looking. Meanwhile, their expatriate communities across the world are known for keeping strong links with their homeland, preserving their traditions and culture.

A ball has a mass of 140 g. What is the force needed to accelerate the ball at 25 m/s2? (Formula: F=ma)

3.5 N
115 N
165 N
4.5 N

Answers

Answer:

The force needed to accelerate the ball at 25 meters per square second is 3.5 newtons.

Explanation:

From 2nd Newton's Law, the net force experimented by the ball ([tex]F[/tex]), measured in newtons, is defined by:

[tex]F = m\cdot a[/tex] (1)

Where:

[tex]m[/tex] - Mass, measured in kilograms.

[tex]a[/tex] - Acceleration, measured in meters per square second.

If we know that [tex]m = 0.140\,kg[/tex] and [tex]a = 25\,\frac{m}{s^{2}}[/tex], then the net force needed to accelerated the ball is:

[tex]F = (0.140\,kg)\cdot \left(25\,\frac{m}{s^{2}} \right)[/tex]

[tex]F = 3.5\,N[/tex]

The force needed to accelerate the ball at 25 meters per square second is 3.5 newtons.

Scientists are closely monitoring caribou populations to examine the effect of global climate change on habitat. The maximum population size for a herd of caribou based on the amount of habitat was 500,000 . A herd of caribou currently has a population size of 198,000 caribou as a result of habitat loss. Which of the following methods should be used to determine the percent change between the maximum population and the current population for this herd of caribou?

a. (500,000 caribou + 198,000 caribou)/198,000 caribou x 100
b. (500,000 caribou - 198,000 caribou) /100
c. (198,000 caribou - 500,000 caribou)/500,000 caribou x 100
d. 198,000 caribou/500,000 caribou x 1,000

Answers

Answer:

c. (198,000 caribou - 500,000 caribou) / 500,000 caribou * 100

Explanation:

Scientists want to determine the percentage change between maximum population and current population of Caribou. The maximum population herd size is subtracted from the current population size. Then the maximum population size is divided by the numerator. Percentage is calculated by multiplying it with 100.

(198,000 caribou - 500,000 caribou) / 500,000 caribou * 100
