SCREENSHOTS ACTUAL EXAM-2026 VERSION
ASSESSMENT
A vet student designs a study to examine the nutritional qualities of dog food. She believes that
a grain-free diet can affect dog health. She selects 3 of the top-selling dog food brands for her
study. From a local humane society, she selects several Chihuahua puppies under the age of 1
year. She will track these puppies for the next year and access their health, include weight,
complete blood count, and paw size. Three puppies will be fed nothing but brand #1 dog food,
10 puppies will only be fed Brand #2, and 10 puppies will only be fed brand #3
How the researcher best improves this experiment ?
The experiment should include 7 more dogs for the brand #1 group
The daily serving size of kibble should be controlled
The experiment needs a clearly defined control of puppies
All of the above are ways to improve the experiment - answer>>All of the above are ways to
improve the experiment
Which of the following is changed during a scientific investigation?
The dependent variable
The control
The hypothesis
The independent variable - answer>>The independent variable
Which of the following are true about the dependent variable ?
A factor that remains constant during the experiment
A factor with data typically plotted on the x-axis
A factor that is measured during an experiment
A factor with data typically plotted on the y-axis - answer>>A factor that is measured during an
experiment
A factor with data typically plotted on the y-axis
,2
Which two types of elements will most likely form an ionic bond ?
Two elements that are in the same period
Two elements that are non-metals and have p orbitals
One element that is a transition metal with d orbitals and one element that is a metal with s
orbitals
One element that is a metal with s orbitals and one element that is a non metal with p orbitals. -
answer>>One element that is a metal with s orbitals and one element that is a non metal with p
orbitals.
Hydrophobic proteins often provide which function in the body?
Digestive enzymes
Provide structure
Carry oxygen molecules
Store energy - answer>>Provide structure
How does renin regulate blood pressure ?
It signals the collecting ducts to expel more urine
It affects the amount of water and salt stored or released by the body
It signals the heart to reduce its systole contraction
It relaxes blood vessels - answer>>It affects the amount of water and salt stored or released by
the body
Which of the following has an acidic pH?
Lemon juice
Blood
Urine
Salt water - answer>>Lemon juice
Urine
, 3
Which of the following are properties of a liquid?
High atomic attraction
Fixed volume
Low pressure
Takes shape of container - answer>>Fixed volume
