Explanation:

The milkweed plant also has high concentrations of cardiac glycosides in its sap. ... In addition, the caterpillar of the monarch butterfly dines exclusively on the sap of the milkweed plant, rendering both the caterpillar and butterfly mildly toxic as well.

Predators know that monarch butterflies are poisonous because of their bright coloration, which acts as a warning that they are poisonous.

This coloration warns potential predators that the animal contains poisonous chemicals. Warning coloration may work particularly well in adult butterflies because the hard body and wings allows a predator to bite the adult, taste the poison, and release the butterfly without killing it.

The direction the blood takes through the circulatory system is important because it makes sure that the nutrients and blood gets to every organ and vein in our body. the direction the blood flows is this. Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart. so we can be the living breathing people we are today.

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.

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.

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.

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.

One kind of model that I can use to show the path of energy and matter through this ecosystem is

According to the question, we are to discuss kind of model you can use to show the path of energy and matter through this ecosystem.

As a result of this, we can see that food chain can serve this purpose because it gives a linear sequence of energy transfer and allows to determine organisms that falls into different types of consumers.

Therefore, food chain is a model which shows a single pathway of energy flowing.

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.

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.

Im pretty sure its D or A

A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another.

Answer:

D.

Explanation:

If it is just a physical change then we can instantly cross out B. and A. as they say in there that they become a new substance and that is not just a physical change. C. is not correct because they combine and there for make a new substance. That leaves D. which makes sense because a physical change would be a change in its size or something that doesn't change the material, this is like when you break a rock, it is now in pieces and smaller but it is still the same rock therefor it is a physical change.

Answer:

The blank is "apart."

Explanation:

Mid-ocean ridges are geologically important because they occur along the kind of plate boundary where a new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a "spreading center" or a "divergent plate boundary." The plates spread apart at rates of 1 cm to 20 cm per year.

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.
