What relationship could scientists track in order to see whether or not blue crabs were the main reason that large zebra mussels have declined?

Answers

Answer 1

Answer: While there were still many zebra mussels in the Hudson River, the overall number of zebra mussels was slightly declining, and they were on average much smaller. Populations of the largest — or oldest mussels — were declining greatly. ... That's because large zebra mussels feed on bigger food particles like zooplankton.

In a village in Africa, the same plot of land is planted year after year, and no fertilizers are used. What problem is likely occurring?
A.
slash and burn farming
B.
overgrazing
C.
overfarming
D.
deforestation

Answers

Answer:

C.  overfarming

Explanation:

The problem that might likely occur with farming a plot of land year after year without any fertilizer is over-farming.

Over- cultivation is the excessive use of a land. This results into nutrient depletion of the land as a result of pressure on the minerals in the soil. Over- cultivation often leads to land degradation. This makes the land unfit for agricultural purpose and a risk of being a desert. One leading cause of over farming is overpopulation. When too many people are farming and they cannot make room for crop rotation or bush fallowing, the pressure on the soil becomes too much.

Describe the holocaust in your own words. Use at least five sentences. Describe and give examples explain why it took place, what it was like for the people of the time, and a number of facilities. Do you have as many details as you can.

Answers

Answer:

The Holocaust was a devastating event that should have never took Place.

The Germans were easily gullible, which sadly led to millions of innocent Jews losing their lives for something they believe in.

It first started in 1941, and ended 4 years later. It took place in such small time and yet left everlasting results that changed the World forever.

The reason for this genocide was the evil ideology of ' Ethnic Cleansing '.  

9 - 11 million Jews have died to this result.

the Evil Man behind this event is named Ad0lf H1tler. He hated Jews for no reasonable answer, and brainwashed the Germans into thinking Jews were all bad. It has been said that He kept Jews with light colored hair ( blonde ) and light colored eyes ( blue ) alive. Nonetheless , a tragedy like this shouldn't have ever happened and should never happen again. ( But if you know about the Muslims in the China Concentration Camps, you would already know it's too late. )

What different types of beaches do we get and how are they formed?

Answers

Answer:

Sandy Beaches

Sandy beaches are the most common of all beach types in the world, and they are found in virtually all continents on earth. This type of beach occurs typically on coasts which experience low-energy waves, which deposit the sand to the beach after being transported by ocean currents. Sandy beaches are most susceptible to backwash erosion, with powerful storms and tsunamis having the potential of stripping a beach of its sand. To remedy the erosion of the sand drastic measures have been employed including beach nourishment where sand is sourced from other places and deposited on the beach.

Pebble Beaches

Pebbles are found on virtually all beaches on earth. However, there are a few beaches in the world that are entirely composed of pebbles, which are known as pebble beaches. The pebbles that cover these beaches vary in size, ranging between 0.1 and 7.9 inches in diameter with the larger pebbles often being found nearer to the shore. Pebble beaches are formed after pebbles carried by ocean currents are deposited on the shore by high-energy waves. Pebble beaches are excellent in the prevention of backwash erosion and dissipation of wave energy due to their porous nature. Pebble beaches are picturesque, and since they are not as popular among tourists as sandy beaches, they are less-crowded making them ideal for a private beach experience. Also known as shingle beaches, this type of beaches is popular among rock collectors, who collect the smooth pebbles which are used in exterior and interior decorations of homes.

Boulder Beaches

Boulder beaches are so named due to the boulders that cover their shorelines. The size of the boulders found on boulder beaches ranges from tiny pebbles to huge house-sized boulders. An example of a boulder beach is the Valugan Boulder Beach, which is covered with boulders. Situated in Batanes, Philippines, the beach is one the true boulder beaches in the world, as the shoreline is entirely made up of boulders.

Shell Beaches

As the name alludes, a shell beach is almost entirely made up of shells. The shells that cover these beaches are mainly from dead mollusks and are deposited on the shore by waves. In some of the beaches, the shell layer can be dozens of feet in depth. Examples of this type of beaches are quite a few and only two exist that are true shell beaches which are Australia’s Shell Beach and Sanibel Shell Beach of the United States. Shell Beach, Australia is one of the two legitimate shell beaches in the world, as it is purely composed of shells. The beach is situated in Western Australia’s Shark Bay which lies about 28 miles from the town of Denham.

Sea Glass

Sea glass is another substance that covers some of the earth’s beaches. Sea glass forms after broken glass disposed of in the sea are acted upon by erosion action, which over time smoothens its sharp edges to result in a piece of glass with smoothened and rounded surface. There are no beaches that are entirely composed of sea glass, due to the small quantities of sea glass that occurs naturally in the earth’s oceans. However, there are a few beaches where large quantities of sea glass cover the surface. Bermuda’s Black Bay Beach is one beach that is covered by sea glass.

Describe the relationship between mass and the three types of end stages of stars.

Answers

Answer:

Higher mass star use their fuel quickly as compared low mass star.

Explanation:

There is a great relationship between mass and end stages of stars because end of stars depend upon its mass. If the mass of the star is higher, it will use up their hydrogen fuel quickly and die while on the other hand, if the mass of the star is lower, it will use its fuel slowly and so more time is taken to end of its life. So we can conclude that mass has a direct relation with end stages of stars.

This is science but there is no choice for that :) Can anyone help me define the following vocabulary terms: universe, solar system, galaxy, cluster, constellation?

Answers

Answer:

Universe:  all of space and time (collectively referred to as spacetime) and their contents.

Solar System: gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly.

Galaxy: a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.

Cluster: a group of stars formed closely

Constellation: a group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure.

Explanation:

Our Solar System consists of our star, the Sun, and its orbiting planets (including Earth), along with numerous moons, asteroids, comet material, rocks, and dust. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy. If we shrink the Sun down to smaller than a grain of sand, we can imagine our Solar System to be small enough to fit onto the palm of your hand.  Pluto would orbit about an inch from the middle of your palm.

what social and economic challenges does North Africa face. (At least 200 words)

Answers

1. Unemployment and underemployment

Unemployment in sub-Saharan Africa stands at around 6%, according to the International Labour Organization. But most of the work available is unskilled or low-skilled, in part because the region has the world’s lowest levels of access to higher education.

So, although many Africans are employed, 70% of sub-Saharan Africa’s workforce is vulnerable. The global average for vulnerable occupations is 46%.

Business leaders in 22 out of 34 sub-Saharan African countries told the World Economic Forum’s 2018 Executive Opinion Survey that unemployment and underemployment were their most pressing concerns.



2. Underinvestment in infrastructure

Physical infrastructure across much of the continent is a challenge to productivity, according to the African Development Bank. It calculates an estimated $130- to $170 billion needs to be invested each year on Africa’s infrastructure, despite a financing gap of as much as $108 billion.

The Value of Sherpa Life taking notes

Answers

Answer:

The text talks about the fateful day when sixteen Sherpas were killed by an avalanche, while walking on Mount Everest. Sherpas are Nepalese who practice mountaineering as a cultural and essential part of their daily lives. Mountaineering has become the main source of income for these Nepalese, which makes them refuse to abandon this practice, in addition to submitting to very dangerous places with little, if any, safety equipment. To help these Nepalese many institutions seek to teach them safer techniques for practicing mountaineering, in addition to teaching first aid. Rescue institutions were also created. Although the company refers to the Sherpas as mountain guides, they have this activity to survive. The author reinforces the need for economic policies that help Sherpas, or at least offer safer activities.

Explanation:

The above notes were taken from the text that shows the risky life of the Sherpas to survive, being victims of a community with few economic policies that establish a good quality of life and supply of needs, making the Sherpas risk their lives in very worrying situations. and that has already resulted in accidents, disasters and deaths.
