Answer:
Earth does not always spin on an axis running through its poles. Instead, it wobbles irregularly over time, drifting toward North America throughout most of the 20th Century (green arrow). That direction has changed drastically due to changes in water mass on Earth.
Explanation:
While walking along the street, you and your friend see an elderly woman whose left arm appears to be swollen to several time its normal size. Your friend remarks that the woman must have been in the tropics and contracted a form of filariasis that produces elephantiasis. You disagree, saying that it is more likely that the woman had a radical mastectomy (removal of the breast because of cancer). Explain the rationale behind your answer.
The following list of events happens during meiosis:
Prophase I: Crossing over between homologous chromosomes occurs.
Metaphase I: Tetrads line up at the metaphase plate.
Anaphase I: Tetrads are separated.
Telophase I: Nuclear envelopes reform around the separated chromosomes.
Prophase II: Chromosomes condense.
Metaphase II: Chromosomes line up at metaphase plate.
Anaphase II: Sister chromatids separate into daughter chromosomes.
Telophase II: Nuclear envelopes reform around the daughter chromosomes.

what is the dominant impact that humans have on alpine glaciers?
The researchers estimate that between 1990 and 2010, some 69 percent of the mass lost by the world's alpine glaciers can be traced to human influence – basically global warming. This 2013 file photo shows the Mendenhall Glaicer where it spills over the mountains above Mendenhall Lake in Juneau, Alaska.
Answer:
Human activity is playing an increasing role in the melting of glaciers, Austrian and Canadian scientists have found. One of the most disruptive effects of climate change, glacier retreat leads to rising sea levels, landslides and unpredictable availability of water downstream.

The shoulder is the most flexible joint in the body, making it the most susceptible to instability and injury. This mobility provides the upper extremity with tremendous range of motion. The shoulder join is also known as a 'ball-and-socket' joint.
What type of shock occurs when bacterial toxins trigger vasodilation and increase capillary permeability
Septic shock occurs when bacterial toxins trigger vasodilation and increase capillary permeability.
Vasodilation occurs during inflammatory processes thereby leading to an increase in blood flow. Septic shock cause the release of numerous vasodilatory chemicals thereby leading to lethal hypotension.
Septic shock is caused by changes in hemodynamic profile as a result of endothelial dysfunction with increased capillary permeability thereby leading to hypotension.

the type of voltage-gated channel that possesses an inactivation gate that temporarily closes after the channel is active is the
The sodium channel possesses an inactivation gate that temporarily closes after the channel is active.
In neurons, sodium channels are responsible for the ascending phase of the action potential (depolarization).
Characteristically, this channel has two transmembrane voltage-dependent gates.When the membrane is depolarized to the threshold, both gates are activated, but since one of them opens rapidly while the other closes slowly, the channel remains open for less than 2-5 milliseconds.Therefore, we can conclude that the sodium channel is responsible for the depolarization and possesses two gates which one temporarily closes after the channel is active.

O vena cava; aorta; right ventricle; right atrium.
O pulmonary vein; left atrium; left ventricle; aorta.
Answer: pulmonary vein; left atrium; left ventricle; aorta
Explanation: I just did this question in the final exam of A&P and it was correct, hope this helps:)
The basic pattern of blood flow from the lungs to the rest of the body is: pulmonary vein; left atrium; left ventricle; aorta. The option (B) is correct.
What are pulmonary vessels?Pulmonary veins are blood vessels that carry oxygen-rich blood from your lungs to your heart. Your pulmonary veins are part of your body's pulmonary circuit. This is a system of blood vessels that moves blood between your heart and your lungs. This circuit also includes your pulmonary arteries.
For the exchange of gases to occur effectively, the lungs require a dual vascular supply known as pulmonary and systemic circulations. The pulmonary circulation is responsible for bringing deoxygenated blood from the body to the lungs for gaseous exchange and then returning oxygenated blood to the heart.
There are 4 total pulmonary veins—with 2 pulmonary veins coming from each lung, left and right—that empty into the left atrium of the heart.

Answer: Researchers argue that robust Australopithecines should be classified in a separate genus called Paranthropus.
Explanation: The "robust" australopiths are a group of fossil hominins that existed in East and southern Africa between approximately 2.5 and 1.4 million years ago (Ma). They are referred to here as members of the genus Paranthropus, though considerable disagreement about their proper taxonomy persists. (credit to the internet)
Explain how pollution from one location
can affect the environment far away from the
source of the pollution
Answer:
Air quality is affected by natural processes. Wind can move pollutants from their source to far-away locations. It can still spread and harm living creatures and destroy their environments.
Explanation:
Air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.
What is Pollution?Pollution is defined as the introduction of harmful materials into the environment where the harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash which can also be created by human activity, such as waste or runoff produced by factories. Pollutants harm the quality of air, water and land.
Many things produce pollution such as cars spewing pollutants from their exhaust pipes. Burning coal to generate electricity pollutes the air. Industries and homes generate waste and sewage that can pollute land and water. Pesticides which is chemical poisons used to kill weeds and insects which is seep into waterways and harm wildlife.
Thus, air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.
