Answer:
a. food pellet
Explanation:
In classical conditioning, an unconditioned stimulus is the stimulus that naturally elicits an unconditioned response. The unconditioned stimulus is usually paired with a neutral stimulus, and after pairing with a neutral stimulus, the neutral stimulus becomes a conditioned stimulus that elicits a conditioned response alone.
In the experiment described above in the question, <em>the unconditioned stimulus is the food pellet,</em> which naturally elicits the response of the rat to wait at the far left corner of the cage. The neutral stimulus which is paired with the food pellet is the vanilla scent, which now becomes the conditioned response, when paired alone.
Answer: the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3
Explanation:
We know that; Gram negative bacteria looks pale reddish in color under a light microscope from Gram staining.
therefore
There are 30 red bacterial colonies counted.
1 mL of from tube 1 was removed and added to tube with 99 mL saline (tube 2) dilution is 1/100.
transferred volume into the plate is 1 mL.
Now, we have to determine the cfu/g Gram-negative bacteria in the fecal sample
Formula to calculate CFU/g bacteria in fecal sample is expressed as;
C = n/(s×d )
where C is concentration (CFU/g)
, n is number of colonies
, s is volume transferred to plate
, d is dilution factor.
so we substitute
C = 30 / ((1/100) × 1)
C = 30 / 0.01
C = 3000
C = 3.0 × 10^3
THERFERE, the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3
Hi! I'm assuming you know the four states of matter- solid, liquid, gas, and plasma.
Putting them into a crime scene, however, is tricky.
Depending on which type of crime scene it is, there will be different types of states of matter in each, or possibly multiple.
Liquid can be seen as blood if it was a murder. Solid can be seen in that same crime scene if the murderer by chance left his knife, gun, or solid device they used to commit the murder. In other cases, gas can be seen used to kill someone because of it's toxicity. Plasma is a hard one, though, but can be seen in blood as well, because our blood is made up of plasma and other materials.
Hoping I helped, and I'd love to receive brainliest answer! :)
Scoville units is the scale used to determine how "hot" a pepper is.
A sweet bell pepper, which isn't spicy at all, has a ranking of 0.
The Carolina Reaper, one of the hottest peppers in the world, has a ranking of up to 2,200,000.
