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.


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.

Describe how hibernation has helped bear species survive. Compare the needs of the organisms to the traits.

It's helps them survive throughout winter and thrive without food during winter too. Before they go into hibernation they consume a large amount of food which helps their heartbeat slow down. Other animals that don't hibernate have their source of food during the winter too, which is the reason why they don't hibernate.

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.

How a light year is used to measure distances in space?

Answer:Astronomers use light years to measure distances in space because space is so massive and distances so far that conventional numbering is inadequate and unmanageable. One light year is a distance measurement equivalent to six trillion miles.

A recipe gives the instructions below. After browning the meat, pour off the fat from the pan. To further reduce fat, use a strainer. What type of separation methods are described in the recipe? A. decantation and screening B. distillation and screening C. decantation and centrifugation D. distillation and filtration

Based on the given instruction above, I can say that the separation methods that are being used in the recipe are DECANTATION AND SCREENING. The answer would be option A. When we say decantation, this is a process of separating liquids in order to remove the layer of liquid that has precipitates in order to produce a cleaner product. Hope this helps.

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

What happens to light images once they are in the retina? The retina interprets the images. The images are sent to the cornea. Our eyes blink. The images are sent to the brain.

I mean the light is made up from some kind of particle, when these hit the retina electrical signals travel through the optic nerve and our brain does the rest.

But what about the light particle that hits the retina? Where does it go? Is it absorbed like with skin?

I imagine we must do something with it since our eyeballs would get clogged up with a load of old light otherwise.

Which list describes the path oxygen takes to the lungs? A. Larynx, trachea, pharynx, bronchi B. Trachea, bronchi, pharynx, larynx C. Pharynx, larynx, trachea, bronchi D. Bronchi, trachea, pharynx, larynx


The correct answer is option C.


The path of oxygen from the atmosphere to the lungs can be described from the nasal cavity to the alveoli. The oxygen is inhaled with air during the breathing process that travels from the nasal cavity to the pharynx that is tube or tract where mouth or oral cavity and nasal cavity combined. Oxygen moves from pharynx to the larynx and then to trachea or the windpipe.

The trachea is a tube that extended to the larynx to the 2 primary bronchi. Oxygen moves from the trachea to the bronchi. Bronchi are the main passage of oxygen to the lungs. Bronchi shuttle air to and from the lungs. These are of three types and oxygen travels into each in order first primary bronchi then secondary and in last to tertiary bronchi and bronchioles and ultimately to the site of gas exchange called alveoli.

Pathway - nasal cavities  > pharynx > trachea >bronchi (primary bronchi (right & left) > secondary bronchi > tertiary bronchi)> bronchioles > alveoli.

Thus, the correct answer is option C.
