Question 1 linnaeus created a three-kingdom classification system. more kingdoms were later added to this classification. what does this highlight about scientific knowledge? scientific knowledge can be revised with time. scientific knowledge about living things is incorrect. scientific knowledge can be used for personal gain. scientific knowledge is based on the opinion of scientists. question 2 both pine trees and ferns are multicellular and have the ability to synthesize their own food. based on the concept of domains, what do they have in common? they both belong to kingdom animalia. they both belong to domain eukarya. they both belong to domain archaea. they both belong to kingdom bacteria. question 3 which of the following is true about scientific knowledge? it never changes. it is durable. it is based on opinion. it is untested. question 4( the following diagram shows the branching tree diagram for some animals. a slanting line is shown. there are five lines drawn vertically on this line at equal intervals. shark, frog, kangaroo, lion and chimpanzee are written on top of each vertical line in order from left to right. common ancestor is written on the left end of the line. there is a black circle between each pair of these vertical lines. the first black circle is before shark and says vertebrae. the second black circle is between shark and frog and says lungs. the third black circle is between frog and kangaroo and says mammary gland. the fourth black circle is between kangaroo and lion and says placenta. the fifth black circle is between lion and chimpanzee and says large brain. which derived characteristic is shared by at least four organisms? large brain lungs mammary glands placenta question 5 what is the name of the bone that makes up the backbone in humans? cartilage skull tendon vertebrae question 6 leah suffered from a bacterial infection. white blood cells her recover from the infection. which two organ systems are mainly involved in this process? immune and circulatory circulatory and respiratory respiratory and reproductive immune and musculoskeletal question 7 which of the following may cause asthma? old food sleep stings tobacco smoke question 8 which nutrient is a source of quick energy? carbohydrates minerals proteins vitamins question 9 what is a pathogen? a microorganism that in digestion a microorganism that causes diseases an organism which is harmed by fungi an organism which is harmed by a virus question 10 how many kingdoms are there in the classification system? 3 4 5 6 question 11 what do endocrine glands use as messengers? blood hormones target organs zygote question 12 which of the following describes an interaction between the endocrine system and the excretory system? the pancreas regulates blood glucose through hormones. the pancreas produces digestive juice to break down nutrients. the adrenal hormones regulate excretion of salt through urine. the adrenal hormones produce adrenaline in response to excitement. question 13 which of the following describes how kidneys maintain homeostasis when water consumption is high? by eliminating more solid waste by eliminating less solid waste by decreasing urine output by increasing urine output question 14 which of the following is the narrowest level of classification according to the linnaean system? domain family kingdom species question 15 which of the following is a hereditary disease? huntington's disease influenza lyme disease strep throat question 16 the following table shows the symptoms in four patients. each patient suffers from a different disease. patient disease cause symptom a tuberculosis bacteria chest pain, coughing b polio virus paralysis c stomach cancer environmental stomach pain, vomiting, nausea d food poisoning bacteria vomiting, loose stools which patient's digestive system is affected by an infectious agent? a b c d question 17 the following diagram shows the branching tree for four kingdoms and some of their shared derived characteristics. a slanting line is shown. there are four lines drawn vertically on this line at equal intervals. there is a black circle between each pair of these vertical lines. protists, plants, fungi, animals are written on top of each vertical line in order from left to right. common cell is written on the left most end of the sloping line. the second black circle has mostly multicellular written on it. the first black circle has x written on it. what shared characteristic can be written at point x? use complete sentences to explain your answer. question 18 imagine that your finger is accidentally caught in a closing car door. describe the path of stimulus and response that would happen in the nervous and musculoskeletal systems. question 19 the normal range of blood glucose is 70–120 mg/dl. a person has a blood glucose level of 170 mg/dl. based on your knowledge of the endocrine system and hormones, explain the likely cause for the person's condition.
