Why are monarch butterflies poisonous?
How do predators know they are poisonous?
How does a monarch's coloration help both the butterfly and the predator?
Answer:
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.

Answer:
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.

One kind of model that I can use to show the path of energy and matter through this ecosystem is
Food chain; shows a single pathway of energy flowing, making it easy to see which organisms are primary, secondary and tertiary consumers.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.

physical change
A. the process in which new substances are formed during a chemical change
B. a change in matter that results in a change in the identity of matter
C. a combination of two or more substances
D. a change in matter that does not result in a change in the type of matter
Answer:
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.
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.

Explanation:
You know its the endoplasmic reticulum when it surrounds the nucleus and is warped. It is confused sometime with the Gogli apparatus. But the Gogli apparatus is thicker and straighter.
Nucleolus is the brain of the nucleus
Lysosomes are big circles, ribosomes are small circles. Ribosomes are usually found around the Endoplasmic Reticulum
Mitochondria is the tic-tac looking thing with lines on it. This is the powerhouse of the cell. "Mitochond-rhianna"

The biggest mountain range in the world is found under the Atlantic Ocean and is called the MidAtlantic Ridge. New crust is found along the ridge. The mid Atlantic ridge is along a divergent boundary where plates are moving ______________________
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.
