MODELING EARTHS TILT - Edge
Type several paragraphs describing how your models showed the effect of the rotation of Earth on day and night and the effect of Earth's tilt on seasons and regional climates.
Answer: When watching the stars at night, they do appear to move very slowly. This is because the Earth is constantly moving. The Earth completes one “rotation” every twenty-four hours. A rotation is when the planet spins around once. The Earth rotates counterclockwise; this is why the Sun “rises” in the East and “sets” in the West. It is not the Sun’s movement that causes days, but rather the Earth turning around in front of the Sun.
The Earth’s axis (the point at which it rotates around, for example, if you were to spin around while standing in one spot, your axis would be an imaginary line running through your head straight down to your feet) is in line with a star named “Polaris”. Polaris is also known as the “North Star” since it is directly above the Earth’s axis.
Since this star is directly above the Earth’s axis, it does not appear to move, however, the rest of the stars in the sky move around Polaris (for example: when you spin around, the object directly above your head does not appear to move but everything else seems to spin around that object). Polaris is only seen in the Northern hemisphere and it belongs to the Little Dipper constellation (it’s the last star at the end of the “handle”). Another type of motion is known as “revolution”. Revolution is when one object completes a circular path around another object. The Earth takes 365.24 days to revolve around the Sun. This is why a year is 365 days long. During the year the Earth is angled differently towards the Sun. These changing angles provide us with different Sun intensities and therefore we get four different seasons. Since the Earth is at different positions in space over the year, we see different constellations throughout the year.
The model of the globe shows how the earth rotates on its axis and thus creates the effect of rotation hence seasons are the product of the rotational motion.
What is the rotation of the earth?The rotation of the earth takes place once every 24 hours and is in respect to the sun's orbit. Earth rotates in a seemly slow motion and spins on its axis.
The planet thus has night and day and rotational main leads to the different season as earth time counterclockwise the corlis force starts into motion and set the direction of north and south winds.
The effect of rotation varies depending on the tilt of the earth which is 23.5 degrees. Hence the region further in poles receives less sunlight than those on the equator.

O Natural selection evolves differences in their body structures.
They immediately develop large differences in structures.
They experience stability over very long periods of time.
They still communicate to go over their differences and how to adapt.
Answer:
MY NAME IS JEFF
Explanation:
When populations are separated into different environments, natural selection can lead to the evolution of differences in their body structures over time. This process is known as divergent evolution, and it occurs when populations that were once similar become increasingly different as they adapt to their respective environments.
What is the explainer to the question asked ?
Over time, populations may develop large differences in their structures as they evolve to better fit their respective environments. For example, if one population lives in a forest environment with lots of trees and vegetation, it may evolve longer limbs and more flexible joints to help it move through the trees.
In contrast, a population living in a grassland environment may evolve shorter limbs and a more compact body shape to help it move quickly across open ground.
While populations may experience stability over long periods of time, this is not always the case. Changes in the environment, such as shifts in climate or the introduction of new predators or competitors, can lead to further evolution and adaptation.
While populations that are separated into different environments may develop differences in their body structures, they may still communicate and exchange genetic material with each other if they come into contact again.
Therefore, This can lead to the exchange of beneficial traits and the potential for hybridization, which can create new genetic combinations and potentially new species over time.

Lake Victoria in East Africa is home to many species of fish called cichlids. In 1954 the predatory Nile perch was introduced to Lake Victoria. The Nile perch became the dominant fish species in the lake by the mid-1980s. The number of cichlid species in the lake decreased as the Nile perch population increased. The perch preyed heavily on cichlid species that fed on algae and debris on the bottom of the lake. Algae in the lake increased, and oxygen levels decreased. The surface area of the gills of some cichlid species has increased in just over 20 years. Which statement explains the increase in gill surface area seen in some of Lake Victoria’s cichlids? Increased gill surface area has allowed the cichlids to change their diet and avoid competing with the Nile perch. Increased gill surface area has allowed the cichlids to be camouflaged and avoid being eaten by the Nile perch. Increased gill surface area has allowed the cichlids to leave Lake Victoria and establish populations in nearby bodies of water. Increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.
The statement that explains the increase in gill surface area seen in some of Lake Victoria’s cichlids is that increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water. The correct option is D.
What are species?The greatest group of organisms in which any two individuals of the right sexes or mating types can result in fertile offspring is commonly referred to as a species.
An organism of a particular species. It serves as both a formal rank in taxonomy and a fundamental unit of biological classification.
The word's first informal usage was rather ambiguous, but there are currently at least 26 alternative ways to use it. The same species includes all members of the same sort of animals or plants.
Therefore, the correct option is D, increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.

What role does DNA play in understanding homologous structures, and how is it used to support the Theory of evolution?
DNA enables researchers to pinpoint the alterations that took place to produce homologous structures. This is so because DNA controls the characteristics of the proteins an organism produces and how these proteins are used. The biology of an organism is subsequently affected by these proteins.
What are homologous structures?
A link between structures or DNA descended from a common ancestor is known as homology, which shows derivation from that ancestor.
Structures that are analogous are ones that were not present in the last common ancestor yet are physically (but not genetically) comparable.
Partial homology is also possible; novel structures can arise by combining various developmental routes.
Homoplasy, which is further broken down into parallelism, reversal, and convergence, is another name for analogy.
Therefore, researchers can identify the changes that occurred to form homologous structures using DNA. This is true because DNA regulates both the properties of the proteins that an organism generates and their functions. These proteins consequently impact an organism's biochemistry.

What does a scientist need to know to figure out the relative age of a rock layer?
A. the age of the layers above and below the rock
B. the age of the fossils of the top layer
C. the rate of decay for all elements in the rock
D. the radioactive element in the rock
The rate of decay C
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
Answer:
A is the answer, this is because deposition has been happening on earth for ages so as time goes by more deposits form layers on earth, including the remains of animals and plants that would later become fossils.

3. This living sea star and tossi sea urchin both have body structures that paris
are formed along five lines. What best explains why both species have this
five-lined body structure?"
sea star
fossil sea urchin
The sea star and sea urchin are different species, so they must not share an ancestor
population. They must have inherited this five-lined body structure from separate
ancestor populations
The sea star and sea urchin both share the same ancestor population that had a five
lined body structure. They inherited this structure from the ancestor population
It is impossible to say, Fossils are very old; therefore, we cannot make observations of
the sea urchin's ancestors, and we cannot explain its body structure,
All species have their own specific body structures, so it is a coincidence that this sea
star and sea urchin each have this specific type of five-lined body structure,

A weather forecast shows that it is humid and warm today, and the temperature is expected to cool off later. How will this affect the weather?
A) Air pressure will decrease.
B) Clouds and rain will form.
C) The weather will be sunny with a clear sky.
D) The weather will remain humid and warm.
Clouds and rain will form will be the resulting effect of the mentioned weather which is humid and warm.Therefore, the correct option is B.
What is humidity?Humidity is a measure of the amount of moisture or water vapor present in the air. Specifically, humidity refers to the amount of water vapor present in the air compared to the maximum amount that the air could hold at a given temperature.
When the air is warm and humid, it can hold a lot of moisture. However, as the temperature drops, the air's ability to hold moisture decreases, and the excess moisture may condense into clouds and eventually fall as precipitation (rain or snow). Therefore, a forecast of warm and humid conditions followed by cooler temperatures suggests that clouds and rain are likely to form.Therefore, the correct option is B.
