Which of the following correctly compares Ornithischian and Saurischian dinosaurs?
kumpel [21]

Answer:

The option c is partly correct.

Explanation:

None of the statements is completely accurate because:

a. Saurischian dinosaurs include theropod and sauropod dinosaurs, and their common ancestors. Ornithischians comprise neornithischians (ornithopods and ceratopsians), thyreophorans (ankylosaurs and stegosaurs) and heterdontosaurids.

b. Capability to fly has only been documented in fossils belonging to Saurischia (where the birds are also classified in). Feathers, on the other hand, do appear in the two clades. Feathers, however, are not a trait exclusively associated to flight.

c. This is a correct comparison between ornithischians and saurischians in the sense that the attributes do belong to these clades, but when comparing animals there most be a comparison that reflects a pattern. Ornithischians have leaf shaped teeth suited to eat plant material, whereas saurischians have teeth for a carnivore and herbivore diet.

d. Sauropods are saurischians and they evolved herbivory from a meat-eater ancestor.

Answer:

Explanation:

We are being provided with little information about the question in the study.

The 50 ml is required to make an unknown solution which has a mass of 5g,

SO, we are to determine the amount of grams that will be needed to make the product.

We are not given information about the product, as such this will be difficult and impossible to answer.

A model for a​ company's revenue from selling a software package is ​R(p)equals=−2.52^2400​p, where p is the price in dollars of
dsp73

A model for a​ company's revenue from selling a software package is ​R(p)=-2.5p² + 400​p, where p is the price in dollars of the software. What price will maximize​ revenue? Find the maximum revenue.

Answer: p = $80,  R = $16,000

Step-by-step explanation:

The maximum is the y-value of the Vertex.

Step 1: Use the Axis-Of-Symmetry (AOS) formula to find x:

x=\frac{-b}{2a}

R(p) = -2.5p² + 400

     a= -2.5  b=400

p=\frac{-(400)}{2(-2.5)}

         = \frac{-400}{-5}

        =80

∴ In order to maximize the value, the company will sell the software package for $80

Step 2: Find the maximum by plugging the p-value (above) into the given equation.

R(80) = -2.5(80)² + 400(80)

         = -16,000 + 32,000

         = 16,000
