Step by step
Solved in 2 steps
- Which of the following is the most likely organism to fossilize and be found in the fossil record? The earliest forms of bacteria A jellyfish with a soft body An octopus with a soft body A crustacean with a hard exoskeletonWhich of the following statements is incorrect in the context of fossilization? Minerals dissolved in the water gradually replace minerals in bones Sediments that slowly accumulate on top of the site extert increasing pressure Extreme pressure transforms the mineralized remains into rock. Impressions form detailed imprints of only external structures. Mineral particles settle out of the groundwater and crystallize inside cavities.Which of these processes is NOT a step of fossilization? An organism or its traces become covered by sediments, mud, or ash. Sediments quickly accumulate on top of the remains, and resulting pressure quickly transforms the mineralized remains into rock. Groundwater seeps into the remains, and minerals dissolved in the water gradually replace minerals in bones and other hard tissues. Mineral particles that crystalize inside cavities and impressions form detailed imprints of internal and external structures.
- Transitional Fossils: Which of the following is the correct sequence in the evolution of structures that facilitated the transition to terrestrial environments? Lungs > humerus > wrist > pelvis > neck > digits Lungs > humerus > digits >wrist > pelvis > neck Lungs > pelvis > wrist > humerus > neck > digits Lungs > pelvis > neck > humerus > digits > wristWhich of the following is not a known bias in the fossil record? Fossils from well-studied areas are more likely to appear in the fossil record More abundant species are more likely to be found and in the fossil record Mammals preserve better than birds. Shells and skeletons preserve better than soft-bodied animals.Which organism is most likely to fossilize? A tropical frog A forest dwelling lizard All animals have the same probability of leaving fossil behind A marine snail A jellyfish
- Which statement is true? Fossils can provide information about when life forms existed. Fossils cannot provide information about life cycles and behaviors. Fossils cannot provide information about relatedness of life forms. Fossils can provide information about the entire evolutionary process of life forms.Primate taxa having Y-5 molars AND ischial callosities include: Group of answer choices: ceboidea hylobatidae tarsiiformes cercopithecidaePart 6: Complete the chart below.

Describe how relative dating works. What does absolute dating do? Why is the element carbon-14 important for paleontologists? . Developmental Biology - Embryology Many scientists use what an organism looks like as an embryo, or embryology, as evidence for evolution. The embryos of most vertebrates look very similar and have similar structures. For example, fish, bird, rabbit, and human embryos are similar in appearance in early stages. They all have gill slits and a tail with muscles to move it. Later as the embryos develop, they become less and less similar. What does the study of embryology show when comparing most vertebrates?
