C, B, A ✖
A, B, C ✖
B, A, C ✖
A, C, B ✔

B; What killed the animals? ✖
C; Which animal was better equipped to survive? ✖
D; Which animal is older? ✔
Question 5: How do fossils of the animal Archaeopteryx provide evidence that birds evolved from one group of dinosaurs?
A; Fossils of Archaeopteryx are older than fossils of birds but younger than fossils of dinosaurs. ✖
B; Fossils of Archeopteryx were discovered near fossils of both dinosaurs and birds. ✖
C; Fossils of Archaeopteryx have traits of both dinosaurs and birds. ✔
D; Fossils of Archeopteryx have traits that show they were better able to survive than dinosaurs but less able to survive than birds. ✖
YOU'RE WELCOME!!!!!! Answers are 100% correct, if you got it wrong then you didn't read the very top sentence.
1# The fossils are from a descendant of animal T.

These are 100% correct
If u get these wrong you are either not in Connexus, or this isn't the assignment you have. So this is not my fault u get a bad grade cause I'm telling you this again if u get a bad grade on this, you are either NOT in Connexus or this isn't the assignment you have.
Good day.
TYSM these are 100% correct
If you are for Connexus 7th grade Are Dinosaurs Still With Us? Quick Check THESE ARE CORRECT 100% I PROMISE
answerd is 100% right thank you sir
Question 1: A scientist discovers a fossil of an animal and places it in the fossil record. The organism’s bones are similar to the bones of animal T, which appears earlier in the fossil record. Which conclusion is most reasonable?
Answer: The correct answer is D; The fossils are from a descendant of animal T.
To arrive at this conclusion, the scientist compares the bones of the newly discovered organism with the bones of animal T, which is already in the fossil record. If the bones of the newly discovered organism are similar to those of animal T, it suggests a relationship between the two. However, since the newly discovered organism appears later in the fossil record, it is more reasonable to conclude that it is a descendant of animal T rather than an ancestor.
Question 2: Why do organisms evolve?
Answer: The correct answer is B; Organisms with traits that help them survive and reproduce in their environment pass on those traits.
Organisms evolve because of natural selection. When organisms have traits that are advantageous in their environment, they are more likely to survive and reproduce, passing on those traits to their offspring. Over time, this leads to changes in the traits of a population, and ultimately, the process of evolution.
Question 3: Scientists examine fossils from three different animals. They determine that all three animals share similar structures and record their observations as follows:
--Animal A and animal B have somewhat similar structures.
--Animal A and animal C have very similar structures.
--Animal B and animal C have very similar structures.
The scientists use the similarities to determine the order in which the fossils should appear in the fossil record. Based on the scientists’ observations, which order is the most reasonable?
Answer: The correct answer is A, C, B.
Based on the observations, scientists can determine the order of fossils in the fossil record by analyzing their similarities. Since animal A and animal C have very similar structures, it is reasonable to assume that animal C came after animal A. Similarly, since animal B and animal C also have very similar structures, it suggests that animal B came before animal C. Therefore, the most reasonable order would be A, C, B.
Question 4: Scientists discover fossilized bones from two different animals. The scientists consult the fossil record to learn more about the fossils. Which question will the fossil record best answer?
Answer: The correct answer is D; Which animal is older?
The fossil record consists of the remains of ancient organisms preserved in rocks over time. By examining the layers of rock and the fossils found within them, scientists can determine the relative ages of different species. Therefore, the fossil record is best used to answer questions about the ages and chronological order of different animals rather than questions about their relationships or cause of death.
Question 5: How do fossils of the animal Archaeopteryx provide evidence that birds evolved from one group of dinosaurs?
Answer: The correct answer is C; Fossils of Archaeopteryx have traits of both dinosaurs and birds.
Archaeopteryx is a fossil species that has traits of both reptiles (dinosaurs) and birds. It displays a combination of reptilian features such as teeth, claws, and a long tail, as well as avian features like feathers and wings. This fossil provides strong evidence for the evolutionary connection between birds and a group of theropod dinosaurs. The presence of intermediate features in Archaeopteryx supports the hypothesis that birds evolved from a lineage of dinosaurs.
