Certain seaweeds contain a greater concentration of iodine inside their cells than there is in the seawater surrounding them. The energy required to maintain this concentration difference is most closely associated with the action of
ribosomes
mitochondria
vacuoles
nuclei
Doctors sometimes use a vaccine to prepare the body to defend itself against future infections. These vaccines most often contain
antibodies
antibiotics
white blood cells
weakened pathogens
White blood cells are most closely associated with which two body systems?
circulatory and digestive
immune and circulatory
digestive and excretory
excretory and immune
Anhidrosis is the inability to sweat normally. If the human body cannot sweat properly, it cannot cool itself, which is potentially harmful.
Anhidrosis most directly interferes with:
a feedback mechanism that maintains homeostasis
an immune system response to harmless antigens
the synthesis of hormones in the circulatory system
the enzymatic breakdown of water in cells
Carmine, a compound that comes from the cochineal beetle, shown above, is used as a food coloring.The food coloring is not harmful to most people, but in a small number of individuals, it causes a reaction and affects their ability to breathe. This response to carmine is known as
a stimulus
an allergy
natural selection
an adaptation
The role of antibodies in the human body is to
stimulate pathogen reproduction to produce additional white blood cells
increase the production of guard cells to defend against pathogens
promote the production of antigens to stimulate an immune response
recognize foreign antigens and mark them for destruction
A vaccine contains...
cow pox
a small amount of the pathogen that is weakened or dead
a large amount of the pathogen
small pox
If body temperature is too high, some blood vessels increase in size and sweat glands will excrete sweat, resulting in a lower body temperature. These changes are an example of
a learned behavior
feedback mechanisms
an inherited disorder
genetic mutations
The diagram below represents the formation of a cancerous growth. Which statement best explains the events represented in this diagram?
A gene mutation caused the cells to become muscle cells.
The growth resulted from the introduction of a vaccine.
A gene mutation caused abnormal mitotic cell division
The growth resulted from uncontrolled meiotic cell division.
Research has shown that treadmill training increases the number of certain energy-releasing structures in the brain cells of rats.The cellular structures referred to in this study are most likely
mitochondria
nuclei
vacuoles
ribosomes
Which two systems work together to maintain homeostasis while transporting oxygen throughout the body and removing carbon dioxide?
circulatory and respiratory
respiratory and excretory
circulatory and digestive
respiratory and digestive
If body temperature is too high, some blood vessels increase in size and sweat glands will excrete sweat, resulting in a lower body temperature. These changes are an example of
a learned behavior
feedback mechanisms
an inherited disorder
genetic mutations
The diagram below represents relationships in an ecosystem. What is the primary source of energy in this environment?
cellular respiration in the plants
energy from minerals in the soil
fossil fuels
solar energy
A student notices pairs of cells with an opening on the bottom of a leaf while looking it under the microscope. The main purpose of these openings and the cells around them is
removing excess sugars
synthesis of carbon dioxide
regulating gas exchange
purification of water
a student placed a test tube containing a plant near a light source. He then counted the number of bubbles released by the plant in 1 minute. The gas that was produced was most likely
carbon dioxide
oxygen
nitrogen
all of these
the level of carbon dioxide in our atmosphere has been increasing dramatically. It has been said that growing green plants would help slow this increase. The best explanation for this is that plants
serve as food for herbivores
serve as a nonrenewable resource
remove carbon dioxide from the atmosphere during respiration
remove carbon dioxide from the atmosphere during photosynthesis
over time, a tree that once had a total mass of 300g increased in mass to 3000 kg. This increase in mass comes mostly from
soil that all plants need to grow
oxygen that enters through the leaf openings
chloroplasts that enter the roots and move to the leaves
carbon dioxide that enters through the leaf openings
An experimental setup is shown:
Which hypothesis would most likely be tested using this setup?
Light is needed for the process of reproduction
Glucose is not synthesized by plants in the dark
Protein synthesis takes place in leaves
Plants need fertilizers for proper growth
Which molecule stores the energy produced by cells in the reaction above?
Glucose
ATP
Oxygen
Enzymes
The diagram illustrates a process by which energy is released in organisms.
The energy released in this process was originally present in:
sunlight and then transferred to sugar
sunlight and then transferred to oxygen
the oxygen and then transferred to sugar
the sugar and then transferred to oxygen
The diagram below represents a cell organelle involved in the transfer of energy from organic compounds.
The arrows in the diagram could represent the release of
ATP from a chloroplast carrying out photosynthesis
oxygen from a mitochondrion carrying out photosynthesis
glucose from a chloroplast carrying out respiration
carbon dioxide from a mitochondrion carrying out respiration
A vaccine contains...
cow pox
a small amount of the pathogen that is weakened or dead
a large amount of the pathogen
small pox
Which statement provides a possible explanation for this growth pattern?
The Bionic Pancreas
Until recently, diabetics could rely only on regular blood sugar checks, medications, and low-carbohydrate diets in order to maintain their health.
Bioengineers at Boston University are working to create a bionic pancreas. The device includes a sensor implanted just beneath the skin that monitors blood sugar levels. It sends a wireless signal to a smartphone every five minutes. If the phone receives a signal that blood
sugar is too low or too high, it then sends a different signal to a separate device also attached to the body. This device releases the appropriate hormone into the bloodstream to return
blood sugar levels back to normal.
The corrective actions made by the bionic pancreas on a regular basis in response to changing blood sugar
levels are similar to which natural biological process?
an immune response
biochemical digestion
a feedback mechanism
ATP production
The bionic pancreas sends a signal to a device to release hormones into the bloodstream to regulate blood
sugar. Identify one hormone the device would most likely release.
(a)
According to the passage, the bionic pancreas makes corrective actions that return blood sugar levels back
to normal. This artificial device helps
produce more sugar
break down blood cells
maintain homeostasis
cure their diabetes
Cellular respiration is called an aerobic process because it requires_____
exercise
light
glucose
oxygen
