Everything with wings was put into the same branch of the phylogenetic tree. 3. The function of the human arm is to be able to reach objects Such structures are said to have diverged over time, indicating that at one time, they . The fingers are the phalanges. Ex. For example, whales were once classified as fish because they live in the water and have flippers. Scientists, teachers, writers, illustrators, and translators are all important to the program. The more closely organisms are related, the more similar the homologous structures are. Quadrate Write any five functions of Skeleton system in human body and explain briefly each one of them?

A. HOMOLOGOUS STRUCTURES B. are found in organisms of the same species. This can be helpful to remember. When Charles Darwin first proposed the idea that all new species descend from an ancestor, he performed an exhaustive amount of research to provide as much evidence as possible. An example of homologous structures are the limbs of humans, cats, whales, and bats. Cocci Branchiocranium Skull The chest and shoulders are large and well-muscled to provide power to the wings. These organisms share the same forearm bones because they all evolved from a common ancestor. The scapula or . Both dolphins and sharks use their fins to swim and have bodies that are streamlined for an aquatic environment. Homologous structures occur in organisms that are derived from a common ancestor, while analogous structures do not. do any of the organisms have the same # of differences form human cytochrome c? These species also have a collection of smaller bones in the "wrist" area (called carpal bones in humans) that lead into the "fingers" or phalanges. comparison to human arm in form and function- bat, FORM- thinner humerus, ulna, radius, smaller carpals, longer and thinner metacarpals and phalanges FUNCTION_ bones are smaller so that there is less weight in flight, long metacarpals and phalanges to extend wings, comparison to human arm in form and function- bird, FORM- slightly shorter humerus, ulna, radius; metacarpals fused together fewer but pointy phalanges FUNCTION- bones are thinner for flight, more aerodynamic and light, comparison to human arm in form and function- crocodile, FORM- shorter, thicker humerus, ulna and radius, larger carpals, pointy phalanges FUNCTION- thicker legs to support heavy weight and long metacarpals for swimming.

Color the radius (F) green and the ulna (E) light green. cat Bats were originally thought to be closely related to birds and insects. Light from bulbs and other forms of indoor lighting is typically unpolarized, whereas radio waves picked up by radios or cell phones are mostly polarized.

This is why analogous structures are sometimes used as evidence for convergent evolution. Even though they have the same functionto make the organism able to get airbornethey are structurally very different. Arms and Front Legs The arms of humans have a much different skeletal setup compared with the legs. People who study anatomy define these structures as a body part of one species that closely resembles that of another. Bat 4. Too l Q:Multiple Alleles: Punnett Square (Check all that apply) For specified inlet and outlet temperatures, which one of these two quantities is larger? The skeleton is composed of the hard tissues of the body, and its primary functions are to support the body, to provide a system of levers used in locomotion, to protect the soft organs of the body, and to produce red blood cells (hematopoiesis). what kind of sensory adaptation would you hypothesize the cave fish has to allow it to navigate in a cave, including catching and eating food?

The design of the interior of the bones also makes them strong. sea urchinc. The first item is done for you. b. Whale flippers Far from being a dead organism, the skeleton houses a production power-house. Because of the density and hardness of bone, the skeleton builds the rigid framework to which other body systems attach. Why? According to Melodie Anne Coffman for The Nest, cats and humans share many anatomical similarities within the lungs, heart, digestive system, urinary tract and sex organs. The bone structure of the bat wing is closer to the bone structure of a human arm than it is to a bird wing. Bones of animals are strong and mostly dense, but they don't all have the same structure. Much longer metacarpals. Unlike human bones, birds have a lot more empty space inside their bones. Because of the structure of the skeleton, it is the basis of all movement. I love nature, cats and all animals. Would humans fit this description? whale They also have a long and occasionally sordid history in human myth and folklore, which adds to the perception that they are inhuman, yet graceful, hunters. -carpal 14. bird Spirochete The most obvious difference between a cat and human skeleton is the size.
