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.
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.

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.

Research and describe the biotic and abiotic factors that work together to create your animal’s habitat. You must research and describe at least 5 total factors, maybe 2 from biotic and 3 from abiotic. You mix how you choose as long as you have a mix of biotic and abiotic totaling 5! Look at the last 2 bullet points below for help.
Describe the impact of your vertebrate (animal) on humans.
Describe humans’ impact on your vertebrate.
You must use at least 2 different resources to find your information.
Biotic Factors to explore--- predators, food preferences and supply, population density (how many of that population in that habitat), other species with which your vertebrate interacts in its habitat (think about your symbiotic relationships-mutualism, commensalism, parasitism), disease
Abiotic Factors to explore---temperature range, precipitation, water, topography (what are the land features-hilly, mountainous, flat, combination), wind, shelter, nesting site and place to raise young, escape routes from predators
Answer: Relevance
The scope of abiotic and biotic factors spans across the entire biosphere, or global sum
of all ecosystems. Such factors can have relevance for an individual within a species,
its community or an entire population. For instance, disease is a biotic factor affecting
the survival of an individual and its community. Temperature is an abiotic factor with the
same relevance.
Some factors have greater relevance for an entire ecosystem. Abiotic and biotic factors
combine to create a system or, more precisely, an ecosystem, meaning a community of
living and nonliving things considered as a unit. In this case, abiotic factors span as far
as the pH of the soil and water, types of nutrients available and even the length of the
day. Biotic factors such as the presence of autotrophs or self-nourishing organisms
such as plants, and the diversity of consumers also affect an entire ecosystem.
Influencing Factors
Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting
factors restrict the growth of populations. They help determine the types and numbers
of organisms able to exist within an environment.
Biotic factors are living things that directly or indirectly affect organisms within an
environment. This includes the organisms themselves, other organisms, interactions
between living organisms and even their waste. Other biotic factors include parasitism,
disease, and predation (the act of one anim

I love to hike. Why is going off the established trails destroying nature?
A) Creating new paths causes pressure which causes new rocks to form.
B) Creating new paths causes erosion.
Answer:
A) Creating new paths causes pressure which causes new rocks to form.
For creating new paths causes erosion, one is going off the established trails destroying nature. The correct option is B.
What is erosion?
Erosion occurs naturally when soil and rocks are moved by wind, water, or gravity. People, on the other hand, disturb the natural balance of the landscape and increase the likelihood of erosion occurring.
This can result in soil degradation, vegetation loss, and stream channel changes.
Established trails are intended to strike a balance between human access to natural areas and the need to protect the environment.
When people deviate from established trails, they risk damaging fragile ecosystems, disrupting wildlife habitats, and causing erosion.
Going off established trails can also contribute to the spread of invasive species, which can be harmful to the natural environment.
Thus, the correct option is B.

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.
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.

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.
