In North American forests, two species of birds, nuthatches and brown creepers, forage on the same trees for insects. Brown creepers feed on insects found near the bottom of the tree trunk, while nuthatches feed on insects in the top part of the tree.
The difference in foraging behavior most likely affects the nuthatches and brown creepers by —
allowing the birds to avoid many types of predators
reducing competition between the birds for resources
preventing the birds from interbreeding with each other
establishing dominance between the birds for nesting sites
Some relationships between different organisms are shown in the table. Which table correctly identifies each type of interaction?
Parrotfish are herbivores that are found in coral reefs. To escape predation, a parrotfish will graze with a rabbitfish, which has venomous spines at the tip of its pelvic fins. The rabbitfish does not benefit from this relationship. Which type of relationship do the parrotfish and the rabbitfish have in the coral-reef environment?
Commensal
Mutualistic
Predator-prey
Parasitic
The acacia ant (Pseudomyrmex ferruginia) lives in the bullshorn acacia plant, as shown in the picture. The acacia ant nests and feeds in the plant's hollow thorns. The ant helps protect the bullshorn acacia by attacking insects and grazing animals that come near the plant. The relationship between the acacia ant and the bullshorn acacia is an example of which of the following?
Commensalism
Mutualism
Neutralism
Parasitism
Bats eat insects that damage crops and mosquitoes that are vectors for disease. One million bats can eat several tons of insects per night, saving billions of dollars in pesticides yearly. Agricultural and public health scientists are concerned about the spread of white-nose syndrome (WNS). WNS is a result of a fungus that can infect cave-dwelling bats. While bats hibernate during winter months, the fungus covers the bats' face and wings. WNS has a near 100% mortality rate, and5.7 million bats have died since the discovery of the fungus in 2006. Many scientists are searching for ways to protect these bats. The relationship between this fungus and bats can best be defined as -
Commensal, because the bats provide a surface for the fungus to grow
parasitic, because the fungus obtains nutrients and shelter from the bats.
competitive, because both organisms use caves as shelter during the winter
mutualistic, , because the relationship involves two distinct species living together
Which four body systems interact to allow a person to sneeze?
Muscular, immune, nervous, respiratory
Nervous, respiratory, circulatory, skeletal
Respiratory, endocrine, skeletal, circulatory
Lymphatic, skeletal, respiratory, muscular
Which two body systems must directly interact for vertebrate organisms to exchange gases?
Skeletal and muscular system
Excretory and reproductive system
Circulatory and respiratory system
Digestive and immune system
The female reproductive and endocrine systems work interactively for which main purpose?
To maintain homeostasis by removing waste products from the body
To release neurotransmitters during times of stress
To control hormone levels to prepare the body for pregnancy
To exchange gases to support cellular aerobic respriation
How do the circulatory system and immune system work together to respond to an injury?
Increase blood flow kills healthy cells which prevents infection at the site of the injury.
Increase blood flow removes infects cells which prevents infection at the site of the injury.
Increased blood flow carries white blood cells to the site of the injury.
Increase blood flow allows for an increase in the exhange of O2 and CO2 at the site of the injury.
Which of the following is an example of the endocrine system directly interacting with the nervous system?
The vertebrae protect the spinal cord form injury.
Hormones provide feedback that affects neural processing.
Sensory receptors in bones send signals about body position to the brain,
The brain sends signals that control the speed at which food moves through the intestines.
Which answer choice best describes a community?
Praying mantises caring for their young
Three-spined sticklebacks living in estuaries
Different species of lizards occupying the same niche in a desert
Roosting mother bats recognizing their offspring
The diagram show some of the levels of biological organization. IN which order are the levels in the diagrams?
Population --> community-->ecosystem
Organism --> community-->population
Organism-->population-->community
Ecosystem-->population-->community
Recent studies in bone research indicate that using ultrasound on a broken bone can decrease the healing time by 25%. Which of these are the most basic levels of organization involved when a bone heals?
Cells and tissue
Cells and organ system
Organ system and organism
Tissue and organ system
The human body is composed of organ systems. Which list represents a system organized from least to most complex?
Heart - cardiac muscle - muscle tissue - muscle cell
Lung tissue - trachea - nostrils - circulatory system
Muscle cell - muscle tissue - biceps muscle - muscular system
Integumentary system - skin cell - hair - sweat glands
The table shows some observations made by four students during a field trip to a nature area. Which student made observation of a community of organisms?

Student 2
Student 3
Student 4
