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 ______________________
Answers
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.

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
Answers
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.

Birds share many similarities with a certain group of dinosaurs that includes the Tyrannosaurus Rex and the Velociraptor. Like birds, these dinosaurs had hollow bones and scales. Fossil evidence shows that many had feathers and some could fly. Evidence also suggests these dinosaurs were warm-blooded.
Given the similarities, identify one characteristic that could be used to differentiate birds from dinosaurs.
Answers
Answer:
Size
Explanation:
Dinosaurs, based on recent studies show that they were larger animals and its not possible now for a bird to be the same height or weight as a dinosaur back then
Birds and dinosaurs have found to share many similarities such as presence of feathers, laying eggs, warm blood however the size difference is the main differentiating characteristic between the two.
What are evolutionary links?Different species are related to each other and are gradually undergoing change over time. Evolution in a population affects the physical characteristics of an organism. The ancestors and links between two species can be found with the help of evolutionary links.
The features or evolutionary links between birds and reptiles i.e., dinosaurs are walking on two legs, having feathers, laying eggs, warm bloodedness. All these traits are inherited features from dinosaurs. The difference between dinosaurs and birds is in the size of their body and absence of scales on the birds body.

After Eris was discovered, scientists had to make a decision. Either Eris was the 10th planet in the solar system or it was not a planet at all! And if Eris weren’t a planet, could Pluto be considered one?
Scientists made new rules for what is counted as a planet, and decided that neither Pluto nor Eris qualified.
Based on this information, what did the discovery of Eris make scientists do?
a
The discovery of Eris made scientists rethink the rules for what is counted as a star.
b
The discovery of Eris made scientists rethink the rules for what is counted as a dwarf planet.
c
The discovery of Eris made scientists rethink the rules for what is counted as a planet.
d
The discovery of Eris made scientists add more planets to the group of planets.

Answer:
The answer is C
Explanation:
The reason why is because in the text it doesn't mention anything about these two planets becoming a dwarf planet so it can't be B (excuse the pun) and it doesn't mention anything about the two planets being a star so it can't be A and answer D they did not add more planet to the group of planets so it has to be C.

A few years ago the population of male blue moon butterflies on the island of Samoa declined. One hypothesis for the decline of the male butterflies is that a parasite infected the cells of female butterflies. The parasite was passed to offspring through the females’ eggs and killed the male butterfly embryos. At one point during the decline, nearly all the butterflies in the population were females, but after five years the number of males in the population increased significantly.
Which explanation most likely accounts for the increase in the number of male butterflies in the five years after the initial parasite problem?
Male butterflies in the population that survived were able to prey on the parasites living in the females’ egg cells.
Female butterflies in the population that survived had a genetic adaptation that allowed them to transform into male butterflies.
Male butterflies in the population that survived had a gene that made them resistant to the parasite, and they passed the gene on to their offspring.
Female butterflies in the population that survived were able to protect the male eggs from the parasite and provide extra care for the male offspring.
Answers
One hypothesis which can explain the increase in the number of male butterflies is that the male butterflies in the population survived had a gene that made them resistant to the parasite, and passed the gene on to their offspring. Thus, the correct option is C.
What is Population growth?Population growth is the change in the number of individuals or species in a population. A population is the sum total of all the living organisms which are living in a particular environment.
According to the situation, the number of males in the population has increased significantly. This increase in the number or the population growth of males can be explained as the male butterflies in the population that survived earlier had a gene which made them resistant to the parasite, and they passed on the gene to their offspring which lead to the increase in the number of males in the population.
Therefore, the correct option is C.

What role does DNA play in understanding homologous structures, and how is it used to support the Theory of evolution?
Answers
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.

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?
Answers
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.
...... Predators that taste their food will spit out a Monarch Butterfly. If they have the ability to vomit, after swallowing a Monarch predators will usually do so...... 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.
