If these birds use a sun compass to orient, they will migrate in North direction.

Different birds migrate naturally over distances of hundreds to thousands of kilometers in search of the greatest biological conditions and habitats for foraging, mating, and raising their young. Migratory birds move to areas where conditions are better when the conditions at breeding sites become unfavorable because of low temperatures.

Migration patterns might vary greatly. The bulk of birds travel south to wintering sites throughout the summer from northern breeding locations. Nevertheless, some birds that breed in southern Africa move to northern wintering areas, or horizontally, to take advantage of the milder coastal temperatures throughout the winter. Other birds migrate according to height, ascending a mountain higher in the summer and spending the winter on lowlands.

Yes, shield and strato volcanoes represent two different ends of the volcano morphology spectrum.

Volcanoes are mountain-like formations on Earth's surface that are formed by the accumulation and solidification of molten rock (magma) and volcanic ash emitted from magma vents on or near the surface.Volcanoes can be classified into various types based on their shape, size, and eruption style. Shield volcanoes and strato or composite volcanoes represent two different ends of the volcano morphology spectrum.

Shield volcanoes are broad, gently sloping volcanoes that resemble the shape of a shield lying on the ground. They are formed when lava flows from a central vent or fissure and spreads outwards to form a broad shield-like shape. These volcanoes have very fluid magma that allows for the relatively gentle eruptions and lava flows. Shield volcanoes can be found in the Hawaiian Islands and Iceland.

Strato volcanoes are tall, cone-shaped volcanoes that are composed of layers of lava, volcanic ash, and rock debris. These volcanoes are formed from explosive eruptions that produce ash and pyroclastic flows that harden into layers over time. They can also erupt viscous magma that can cause violent eruptions and form lava domes. Strato volcanoes are found in the Pacific Ring of Fire, such as Mount St. Helens and Mount Fuji.

Answer:

Light-dependent reactions

Explanation:

First of all, the light-independent reactions and the same thing as the Calvin cycle, so your teacher wouldn't put them in the same question if one of them was correct.  Aside from that, even if you have no idea what these things are we can use the names of them to see which one light is involved in.  Aha!  It's the light-dependent reactions because they're dependent on light (and water) to make the chemical energy (NADPH and ATP) to pass on to the next stage, the light-independent reactions.

The estimated temperature when the crickets are chirping at 156 chirps per minute is 27.5 degrees Fahrenheit.

The linear equation that models the relationship between temperature and the number of chirps is T(N) = -0.5N + 105.5.

In this given case, if the crickets are chirping at 156 chirps per minute, we can estimate the temperature by substituting N = 156 into the equation and solving for T.

By substituting N = 156 into the equation T(N) = -0.5N + 105.5, we find:

T(156) = -0.5(156) + 105.5

T(156) = -78 + 105.5

T(156) = 27.5

Therefore, the estimated temperature when the crickets are chirping at 156 chirps per minute is 27.5 degrees Fahrenheit.

Explanation:

False, there is a difference between primate language and human language.

While both primates and humans possess the ability to communicate through various forms of language, there are distinct differences between primate language and human language. Primates, such as chimpanzees and gorillas, use a form of communication known as "primate language," which primarily consists of vocalizations, gestures, and body language. However, primate language is more limited in its complexity and lacks the grammar, syntax, and abstract thinking present in human language.

Human language, on the other hand, is characterized by its rich vocabulary, grammatical structures, and the ability to convey abstract concepts and ideas. Humans can communicate through spoken and written language, allowing for complex communication that is not observed in primate language. Thus, while both primates and humans possess language capabilities, human language is more advanced and distinct in its complexity.

Answer:

Claim: Increasing the amount of foliage does not lead to an increase in the final number of slinquettes with red, short fur.

Evidence: The data table shows the results of eight trials where the amount of foliage was manipulated. In all trials, regardless of the amount of foliage (whether "lots" or "some"), the final number of slinquettes with red, short fur remained at 0. There were no instances where increasing the foliage resulted in an increase in the population of slinquettes with red, short fur.

Reasoning: The evidence from the data table supports the claim that increasing the amount of foliage does not lead to an increase in the final number of slinquettes with red, short fur. This suggests that the presence or absence of foliage does not have a significant impact on the population of slinquettes with red, short fur.

Based on the provided data, it is reasonable to infer that factors other than foliage, such as temperature, fur color mutation, and fur length mutation, may have a stronger influence on the population dynamics of slinquettes. These factors could be responsible for the observed patterns in the data.

It's important to note that the reasoning provided here is based solely on the given data and analysis. In a real scientific investigation, additional factors, experimental controls, and statistical analysis would be required to draw definitive conclusions.

Answer:

140 km per hour.

Explanation:

350 divided by 2.5= 140

The average speed of the train was 140 kilometers per hour.

Speed ​​is a unit used to describe how fast something is moving with respect to another object. Due to its scalar nature, it has only magnitude and no direction. By dividing the distance traveled by an object by the time required to cover that distance, one can calculate its speed.

The formula for calculating speed is as follows:

Speed = Distance / Time

In the International System of Units (SI), the meter per second (m/s) is the accepted unit for measuring speed. Nevertheless, other common units for speed include kilometers per hour (km/h) and miles per hour (mph), depending on the situation and location.

We can use the following calculation to determine the typical speed of a train:

Average speed = Distance traveled / Time taken

In this example, the train covered this distance of 350 km in 2.5 hours.

Average speed = 350 km / 2.5 hours

Average speed = 140 km/h

Therefore, the average speed of the train was 140 kilometers per hour.

The liver cell is more likely to be in G₀ phase compared to the stomach-lining epithelial cell.

This is because the stomach-lining epithelial cell needs to divide more than twice a day to replace the cells that are lost due to wear and tear. Therefore, it needs to keep progressing through the cell cycle and cannot afford to remain in G₀ phase for a long time.

On the other hand, the liver cell divides very slowly, and may only divide once every year or two. Hence, it is more likely to enter G₀ phase during the cell cycle and remain there until it receives a signal to re-enter G₁ and continue with the cell cycle.
