Even when it is cold outside, the human body maintains an internal temperature of 37 °C. Which term describes the maintenance of a stable internal condition?
mitosis
respiration
photosynthesis
homeostasis
A rat approaches a piece of rotting fruit, smells it, takes a small bite, and then runs away. Which statement best explains the reason for the rat’s behavior?
The rat runs away from the fruit to process the new sensory information.
Sensory receptors in the rat’s whiskers respond to input about the texture of the fruit.
The rat’s chemical receptors detect chemicals in the fruit that alert the rat to possible danger.
Information gathered by the rat’s auditory receptors signal that the environment around the fruit is not safe
Which of the following is an example of how the need to maintain homeostasis can cause an organism to change its behavior?
A bear hibernates during the winter.
A tree loses its leaves in the winter.
A human shivers when exposed to cold weather.
Organisms do not change their behavior to maintain homeostasis.
The diagram shows several parts of a human eye.
Which statement best describes how sensory receptors in the eye gather information to be processed by the brain?
The iris controls the amount of light entering the eye.
The lens transmits impulses from the optic nerve to the brain.
The cornea bends incoming light, which is then focused by the lens
Cells in the retina detect light and produce nerve signals sent to the brain through the optic nerve.
Beth has a one-day-old baby daughter. When Beth puts her finger in the baby’s hand, the baby grasps her finger. Which statement best describes why the baby grasps Beth’s finger?
The baby’s reflex to grab is an innate behavior.
The baby’s visual memory recognizes Beth’s finger.
The baby is a day old and has learned to reach for Beth.
The baby’s homeostatic response is to touch objects that are warm
This diagram shows the steps involved when chemical receptors in the nose detect different scents.
Which statement describes the next two steps in the process?
Nerves pass the signal to the brain, where it is processed.
The scent is carried by red blood cells to the brain in blood.
Hormones carry the scent through the body to be interpreted.
If the scent is familiar, it causes a memory to become activated.
A group of students is investigating memory. The students performed an experiment in which they showed letters on a screen to participants, and afterward asked participants to recall which letters they saw. Next, they showed the participants the letters and, at the same time, pronounced the sound that the letter represents. Which prediction and explanation are most likely to be correct?
The participants would remember the most letters during the first trial since their memory was fresh.
The participants would remember more letters during the first trial because the sound interferes with the ability to form memory.
The participants would remember more letters while hearing the letter pronounced because information was received in more than one way.
The participants would remember more letters while hearing the letter pronounced because sound input becomes memory faster than visual input does.
One of the characteristics of living things is that they respond to external changes in their environment so that their internal environment stays as stable as possible.
Identify an environmental change that an animal must respond to in order to keep a stable internal environment
A sudden drop in environmental temperature
A human building a house
A raindrop lands in a pond
The sun sets
One of the characteristics of living things is that they respond to external changes in their environment so that their internal environment stays as stable as possible.
What could happen to an animal if it cannot adapt to a change in the environment
the animal could develop superpowers
the animal could get sick or die
the animal could turn into a new species to survive
Scientists conducted an experiment to show whether the ability to see an object affects a person’s idea of the mass of the object. They used the following procedure:
Obtain two cardboard boxes of different sizes.
Place rocks in each box so that both boxes have the same mass.
Close each box and tie a string to it so that participants lift each box using the string.
Blindfold half of the participants in the experiment.
Ask participants to lift each box using the string and report which one they think has more mass.
Record results.
The table shows the results of the experiment.
Compare how the response to the sensory information was processed differently by the brain of the blindfolded participants and the non-blindfolded participants in the experiment.
Visual information makes them think the larger box has more mass
Visual information make them think the larger box has less mass.
Visual information make them think the smaller box has more mass.
Visual information does not influence their decision.
A student visits a farm and makes these notes in her journal.
Day 1: A chick wanders into an open field, away from its mother and the chicken coop. A hawk swoops toward the chick. The chick sees the hawk and runs quickly back to the safety of the chicken coop.
Day 2: The door to the coop is opened. The chick stays close to its mother, near the chicken coop.
Explain how the danger was processed by the chick’s brain on Day 1, and then how the events of Day 1 affected the chick’s behavior on Day 2.
Day 1 the chicken sees the hawk as dangerous Day 2 the chicken is sick and stay near the coop.
Day 1 the chicken sees the hawk as a playmate Day 2 the chicken is looking to play again.
Day 1 the chicken thinks the hawk is a cloud Day 2 the chicken stays in the coop because it is waiting for the sun.
Day 1 the chicken sees the hawk as dangerous Day 2 the chicken remember the danger and stays near its mother and the coop.
