We observe a frog that carries its babies on its back away from where the eggs hatched. Two questions about this observation follow. Which (X or Y) is an appropriate causal question? X. Does the frog do this to move the babies to a place where they will be safer? Y. Why does the frog expend time and energy moving its offspring from the place where they were hatched?
Select one:
a. X, because this is the more specific of the two questions
b. X, because we can test this idea but not the idea presented in Y
c. Y, because this statement tells what we should expect to find in nature
d. Y, because it is not a hypothesis itself but could be answered by a hypothesis
Ans.
Option D
The option d is not a hypothesis, but it could be answered by a hypothesis. The frog wants a safe place to hatch the egg but a good place to feed and support the baby. Hatching is possible without resources but growing needs a different place.

We observe a frog that carries its babies on its back away from where the eggs hatched. Below are two questions about this observation. (X) Does the frog do this to move the babies to place where they will be safer? (Y) Why does the frog expend time and energy moving its offspring from the place where they were “born”? Which of the two is a true causal question? a. X, because this is the more specific of the two...
ements Constants ents SOLUTION We will look at an example where several forces are acting on an object, but in this case the forces are not all along the same axis. As shown in (Figure 1), a car engine with weight to hangs from a chain that is linked at point to two other chains, one fastened to the ceiling and the other to the wall. Find the tension in each of the three chains, assuming that is given and...
Hello,
Q1: where does the f(1,17) the 1 come from?
Q2, how do i get the second equation from the first
equation?
thanks
Heat treating is often used to carburize metal parts such as gears. The thickness of the carburized layer is considered an important feature of the gear, and it contributes to the overall reliability of the part. Because of the critical nature of this feature, a lab test is performed on each furnace load. The test is a...
How Does Evolutionary Change Occur? "I soon perceived that selection was the keystone of man's success in making useful races of animals and plants. But how selection could be applied to organisms living in a state of nature remained for some time a mystery to me." - Charles Darwin Introduction Fundamentally, evolution is the idea that the form and behaviors of a species are not fixed - that they can change over time. Before Darwin was even born, some scientists...
QUESTION: Please write a one paragraph lab report introduction based on the following experiment below: Organisms must forage for food and other resources that are scattered around a heterogeneous environment. Food availability varies from site to site, but so do environmental conditions that foragers experience (e.g., temperature and wind) and the risks to which they are exposed. Foraging by any organism involves trading off the gains to be made by collecting food against the costs of doing so, including costs...
Beer’s Law Objective : We will explore an application of absorption spectroscopy using calibration curves and Beer’s Law. Use the “LAB : HOW TO…” link from the class website if you need help with how to use balance, Bunsen burner… and such. Introduction: You may write this information in your lab notebook for your own reference. It can’t be cut and pasted. Different solutions have different spectral properties. In this portion of the experiment those properties will be utilized to...
please answer all prelab questions, 1-4.
This is the prelab manual, just in case you need background
information to answer the questions. The prelab questions are in
the 3rd photo.
this where we put in the answers, just to give you an
idea.
Lab Manual Lab 9: Simple Harmonic Oscillation Before the lab, read the theory in Sections 1-3 and answer questions on Pre-lab Submit your Pre-lab at the beginning of the lab. During the lab, read Section 4 and...
will work with up to 3 partners (similar to a lab group) to prepare a written report which analyzes kinetic data that has been provided to you. All student groups will receive data for the hypothetical reaction aAlE) products where a is a numeric variable and A is a chemical variable. The reaction therefore has the form of a decomposition reaction, in which a single substance forms one or more new substances. For consistency, all concentrations start out at 1.000...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
The discussion: 150 -200 words. Auditing We know that computer security audits are important in business. However, let’s think about the types of audits that need to be performed and the frequency of these audits. Create a timeline that occurs during the fiscal year of audits that should occur and “who” should conduct the audits? Are they internal individuals, system administrators, internal accountants, external accountants, or others? Let me start you: (my timeline is wrong but you should use some...
