Let "r" stand for the recessive red hair trait. A person with red hair must have a genotype of "rr" ( one from each parent) in order to have red hair( red hair being the phenotype).

Let "B" stand for brown hair and "b" stand for not brown hair. A person with brown hair can have a genotype of "Bb" or "BB" and have a phenotype of Brown hair. This is becasue brown hair "B" is the dominant trait.

A fertilizer producer finds that it can sell its product at a price of dollars per unit when it produces units of fertilizer. Th
Vilka [71]

Answer:

700

Explanation:

If from the question the price per unit of fertilizer, p(x) = 300 - 0.1x

The cost of x units of  fertilizer = C(x) = 15000 + 125x + 0.025x^2

And we know that Profit = Revenue - Cost

Revenue for x units of fertilizer R(X) = x*p(x)

= 300x - 0.1x^2

Hence Profit: P(x) = R(x) - C(x)

= [300x - 0.1x^2] - [15000 + 125x + 0.025x^2]  

= -0.125x^2 + 175x - 15000

To determine critical values

P'(x) = -0.25x + 175 = 0

Thus x = 175/0.25

x = 700

To maximize profit, the manufactures must produce 700 units of fertilizers

Dr. Graham exposes rats to a vanilla scent prior to receiving a food pellet in the left corner of their cage, but provides no fo
jenyasd209 [6]

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.

Basile [38]
In animals, the circulatory system performs a similar function because it transports vital nutrients around the body of the animal, just like how xylem and phloem transport water, minerals, and sugar to different parts of the plant.
