Slopes that drop or rise sharply in elevation are:
Steep slopes are geographical features that rise or drop significantly in elevation over a short distance. Examples are found in mountainous areas or cliffs by the sea.
Explanation:Slopes that drop or rise sharply in elevation are commonly referred to as steep slopes. These geographical features are characterized by an abrupt change in altitude, with the land rising or falling significantly over a short distance. Steep slopes occur naturally in mountainous or hilly areas. A cliff by the sea, or the side of a mountain range, are good examples of this geographical feature. They're significant because they influence elements like climate, vegetation, and human habitation, as living or farming on a steep slope can be challenging.

Steep slopes, in mathematical terms, are represented by a plate with a high positive or negative slope. In geographical context, these are typically found in mountain areas where erosion forms sharply rising or falling landscapes.
Explanation:Slopes that drop or rise sharply in elevation are referred as steep slopes. In the context of a graph or a line in mathematics, these are represented by lines with a high positive or negative slope. The slope is defined by how much y (vertical distance) changes for each unit of x (horizontal distance) or 'rise over run'.
In geographical terms, steep slopes are commonly found in mountain ranges, where erosion by water and ice create sharp peaks and serrated edges. For example, a mountain formed by upthrusting of the crust will have its rocks subject to erosion, resulting in a steep slope. These are visibly different to the smooth, dull slopes found on non-eroded surfaces such as those found on the Moon or Mercury.

Tina has a history of asthma. what sounds might you hear during an asthma exacerbation?
Final answer:
During an asthma exacerbation, wheezing and possibly crackling sounds may be heard, along with decreased breath sounds if the attack is severe.
Explanation:
These sounds include wheezing, which is a high-pitched whistling sound caused by the restriction of airflow, and is most pronounced when exhaling.
Additionally, during more severe attacks, a health professional might hear decreased breath sounds due to reduced air movement within the lungs. In some cases, a crackling sound can be heard, suggesting the presence of mucus in the airways. It is also possible to encounter signs of increased work of breathing such as the use of accessory muscles during respiration.
Asthma is a chronic respiratory condition where the airway passages narrow and are often accompanied by excessive mucus production, leading to symptoms such as difficulty breathing, coughing, and chest tightness. Triggers like allergens, air pollution, infections, and exercise can provoke these asthma attacks.
Prompt and proper management of an asthma attack, especially if presenting severe symptoms such as cyanotic lips or confusion, is imperative for an asthmatic individual, and may involve the use of fast-acting medications like bronchodilators.
The endocrine and nervous systems are considered _________ homeostatic regulatory mechanisms
The endocrine and nervous systems are considered extrinsic homeostatic regulatory mechanisms.
What is Extrinsic mechanism?During hemostasis the extrinsic pathway is the shorter pathway in contrast the intrinsic pathway is the longest pathway.
Endothelial cells release tissue factor when the damage to the vessel which goes on to activate factor VII to factor VIIa, and Factor VIIa goes on to activate factor X into factor Xa. at this point both extrinsic and intrinsic pathways become one.
The difference between Extrinsic and Intrinsic pathway is that intrinsic pathway is activated by factors in the blood, while extrinsic is activated by tissue factor, but in the end both factors result in activation of factor X.

Trilobites are index fossils because they ____.
a.
changed slowly through time
c.
exhibit specific characteristics
b.
lived over large areas of the world
d.
all of the above
Answer:
d. all of the above
Explanation:
Trilobites are an extinct class of marine arthropods, having been one of the most frequent fossil groups in the period between the Cambric and the Devonian, and are at this time still quite biologically diverse. Trilobite fossils are considered index fossils because they change slowly over time, exhibit specific characteristics and have lived in large areas of the world.
Index fossils refer to an organism that has had a wide geographical distribution in the past, although it has lived for short periods of time, and whose remains have not only been conserved in abundance but are also easy to identify.
During the first cycle of the natural sleep cycle. REM sleep lasts for about how long?
During the first cycle of the natural sleep cycle, REM sleep usually lasts for about 10 minutes. It is characterized by rapid eye movements, high brain activity, and a lack of muscle tone. The duration of REM sleep increases with each sleep cycle throughout the night.
Explanation:The question is asking about the duration of REM sleep during the first cycle of the natural sleep cycle. To answer this question, we first need to understand what REM sleep is. REM, or Rapid Eye Movement sleep, is a phase of the natural sleep cycle characterized by rapid movements of the eyes, high brain activity, and a lack of muscle tone. This is often the stage in which dreaming occurs.
The duration of REM sleep changes throughout the night, with each sleep cycle. During the first sleep cycle, REM sleep typically lasts for about 10 minutes. However, as the night progresses, the length of each REM stage can increase, with the final REM stage of the night potentially lasting up to an hour.

An enveloped virus is dependent on the envelope for its ability to infect a host cell. Which virus most likely uses this mechanism?
Answer:
HIV
Explanation:
HIV is a retrovirus, is an enveloped virus classified in the Lentiviridae subfamily and is a sexually transmitted infection. This virus infects a host cell by attacking the immune system, which is responsible for defending the body from disease. The most affected cells are CD4 + T lymphocytes. The virus is capable of altering the DNA of this cell and making copies of itself. After multiplying, it breaks the lymphocytes in search of others to continue the infection.

Which bonds are hydrolyzed during the breakdown of starch during digestion?
A.) 1 and 4
B.) 1 and 3
C.) 1 and 2
D.) 3 and 4
E.) 2 and 3
Answer:
The correct answer is A.) 1 and 4
Explanation:
Starch is the branched polymer made up of units of D- glucose. It contains amylopectin and amylose. They are found in plants and store glucose for energy in plants.
Amylose is made up of unbranched polymer of α-D-glucose residue joined together by α1-4 glycosidic bond and amylopectin is also made up of α-D-glucose units joined together by α1-4 glycosidic bond but it is a branched polymer with α1-6 branching point after some glucose residues.
So α- amylase is the enzyme that breaks down the α1-4 glycosidic linkage between two glucose units of starch to produce glucose and maltose residues. So the correct answer is A.) 1 and 4.

The finding that ___ can cause channel-swapping is consistent with early filter theories of auditory attentional selection.
Final answer:
Motivation can cause channel-swapping, consistent with early filter theories of auditory attentional selection and evidenced by signal detection theory and synaptic plasticity influencing perception.
Explanation:
The finding that motivation can cause channel-swapping is consistent with early filter theories of auditory attentional selection. Motivation influences our perception, such as when expecting an important phone call while showering and thinking we hear the phone when it's not actually ringing.
This phenomenon is an example of signal detection theory, which helps explain our ability to discern a meaningful stimulus amidst noise. Furthermore, the connections between neurons on both sides of the brain enable us to detect slight differences in sound stimuli, aiding in auditory discrimination.
Another key aspect is synaptic plasticity, which allows the brain to integrate and respond to new information, as seen in experiments with auditory tones and foot shocks.
External sounds that are significant, like the crashing of dishes, can penetrate our attentional filters due to the bottom-up attentional capture mechanism. All of these principles contribute to our understanding of how attention and perception work in conjunction with auditory stimuli.
