The Mute Swan is a species of bird with an orange-reddish bill and white feathers. It is naturally found in Europe and Asia but can sometimes be found in the United States as a result of the importation of these non-native birds. Mute Swans are one of the heaviest flying birds and consume up to 8 pounds of vegetation each day. How will the migration of Mute Swans into an area most likely affect the birds native to that area? A. The native birds will adapt to consume less food or different types of food. B. The native birds and the Mute Swans will coexist peacefully together. C. The native birds will decrease in number because there is not enough food for all the birds. D. The native birds will immediately migrate to another area.

Consider this northern site of primary succession following the retreat of a glacier. As we move from left to right, describe some improvements in the abiotic factors that support plant growth. A) change in climate over time B) less competition for water resources due to biodiversity C) improved soil quality: increased humus and water retention D) increased population density resulting in decreased pathogens

Answer: C. improved soil quality: increased humus and water retention.

Explanation:

An ecological succession brings change in the type of living species residing in an ecosystem with respect to changes that occur in the abiotic (non-living factors) with respect to time.

A region affected by a retreating glacier will not be suitable for the growth of living species. The soil may be lacking minerals and will be in the permafrost condition. So for the initiation of succession the improvement in soil an important abiotic factor is required. The improved soil quality will allow the accumulation of organic and inorganic minerals by physical and biological processes. This will help in formation of humus and water retention.

How does a mirror affect the path of light? 1) Light rays are reflected by mirrors. 2) Light rays are interrupted by mirrors. 3) Light rays pass through mirrors at an angle. 4) Light rays are scattered by mirrors.

Answer: Option A

Explanation: The lights that is incident on a mirror will be reflected back as it is a smooth surface and it reflects back the light.

the light will be reflected by the same angle as it was incidented. The angle of incidence can be defined as the angle by which the light ray falls on the surface of the mirror.

The angle by which the light reflects back is known as the angle of reflection. Being a smooth surface light ray is reflected back.

Why are the Galapagos Islands important in our understanding of how species adapt to their enviornment? Discuss it's geographic location, what Darwin concluded, and the researcj of the Grants

Charles concluded that the finches beaks are examples of adaptive radiation. To fit in the island, they had to adapt to the conditions. This lead to Charles’ theory of natural selection. Charles came to the conclusion of evolution and natural selection. Natural selection is the process where organisms adapt to their environment to survive and produce more offspring. Evolution is where different kinds of living organisms are thought to have developed. These theories have changed science forever and leave today’s scientists marveling of his theories. 

The Galapagos Islands are located in Ecuador and sit on the Pacific Ocean.
The Galapagos Islands were formed from 3 million to 5 million years ago. Volcanic eruptions typically shield volcanoes formed the islands. They are located over a “particularly hot mantel” that causes volcanic activity. The outcome of many eruptions were islands because the left overs were pushed to the surface. The Galapagos islands are pretty big reaching an area of 3,093 miles. The temperatures range from 69 to 84 degrees creating a typically warm climate. 

All plants and animals are native to the islands. It is likely that sea animals swam there, birds flew there (with the help of wind), and reptiles and small animals were carried on rafts of vegetation. Since all the plants and animals are native to the islands, they had to adapt to the new food source and climate. Beaks, size, etc. are all changes made to these organisms to be able to live on the islands. 

The Grant’s research on the Galapagos Islands showed that evolution exists and can happen over a course of two years. They proved Darwin’s theories are true.  They observed the evolution of the finches and are said to have seen it with their own eyes. They spent years measuring beaks of the finches and documented change overtime.

Darwin’s research showed that finches beaks are different to fit their food source. It also started the theories of evolution and natural selection.

1. How do your skeleton and muscular system work together, 2. What type of muscle tissue would you find in the heart? blood vessels? toes?

The answer to your first question involves a connection between your actions and your brain. Your bones and muscles work together through a series of impulses and signals communicated between the brain and skeletal muscles. In order to move, the nervous system then sends signals a skeletal muscle to contract. When the muscle contracts, this movement causes the attached bone to follow.

And as for your second question, 
The muscle tissue in your heart is cardiac, the muscle tissue in your blood vessels is smooth, and the muscle tissue in your toes is skeletal. 

I hope this helps you, have a nice day!

Sort the phrases into the appropriate bins depending on which type of postsynaptic potential they describe. If a phrase describes both types of potentials, drag it to the "both" bin.

Excitatory postsynaptic possibilities (EPSPs) are excitatory in light of the fact that they make the postsynaptic neuron more prone to produce an activity potential by depolarizing the layer (making the film potential less negative) and conveying the layer potential more like an edge. This is regularly expert by opening ligand-gated Na+ diverts in the postsynaptic layer, which enables Na+ particles to enter the cell. 
Interestingly, inhibitory postsynaptic possibilities (IPSPs) make it more troublesome for the postsynaptic neuron to create an activity potential by hyperpolarizing the layer (making the film potential more negative) and moving the film potential more distant from the limit. This is frequently proficient by opening ligand-gated K+ directs in the postsynaptic layer, which enables K+ particles to leave the cell. 
Despite whether they are excitatory or inhibitory, all postsynaptic possibilities are reviewed, implying that their sizes are variable. (Activity possibilities, then again, are all-or-none occasions.) And on the grounds that a postsynaptic potential is not proliferated like an activity potential, its greatness diminishes with separation from the neurotransmitter along the cell body.

QUESTION POSTED AT 28/03/2020 - 12:05 PM

In a paragraph address these following questions: • How does an underwater earthquake cause a tsunami? • Why do some earthquakes cause more damage than others? the paragraph needs to also include the following things: • discuss how the different types of waves are formed and describe how the waves travel • explain how scientists use waves to track and analyze earthquakes • cover recent events involving earthquakes and/or tsunamis that illustrate the points made in your explanation

What is an Earthquake

Earthquakes are vibrations in the earth's crust They occur along all plate boundaries but are more destructive usually at destructive plate boundaries

How are they measured

The magnitude or size of an earthquake can be measured by an instrument called a seisometer and are shown on a seismograph. The earthquakes are measured on the Richter scale from a value of 1 to 10. Each level of magnitude is 10 times more powerful than the previous. Therefore a level 7 is 100 time more powerful than a level 5.

Why do some earthquakes cause more damage than others?

Some earthquakes take place in rural areas where few people live and little is damaged

If they occur near large urban areas with many people, transport services, large buildings and services such as gas and electricity - there can be a great amount of deaths and damage

In Poor countries - LEDC's they have poorly built buildings, few emergency facilities, and the equipment to help rescue people - a good term to use is that they have a poor infrastructure.

In rich countries - MEDC's such as the USA they prepare for an earthquake with drills and have a great deal of trained emergency personnel and equipment to go to help the injured. They also try to build to withstand earthquake damage - ie The Transamerica building

The time of day can be important - If the earthquake hits when it is the rush hour or when there is a large number of people located in a certain area - this can cause a great loss of life

Obviously if they occur near to coasts then Tsunamis can cause a great deal of damage and deaths such as the 2004 Boxing Day Tsunami
