Answer 1
Answer :

A. true

Explanation:
Ocean floor evidence includes molten materials, magnetic stripes, and the ages of rocks themselves from drilling samples of rocks
Answer 2
a. true, Oceanic drilling by the Glomar Challenger between 1968 and 1983 produced the first accurate data of seafloor age. Glomar Challenger data showed a clear progression of increasing age with distance from the mid-ocean ridge. Sediment next to the ridge was youngest.

Answering the following questions will help you to focus on the outcomes of these experiments:

How does the length to height ratio (the IMA) of trial 1 compare to trial 2?
Why is the actual mechanical advantage less than the ideal mechanical advantage in each of the trials?
If a machine was 100% efficient, how would the AMA compare to the IMA?
Write a summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph.

According to your data, was your hypothesis correct? (Be sure to refer to your data when answering this question.)
Summarize the conclusions that you can draw from this experiment. Use the questions above to guide your ideas.
Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
Give at least three examples from everyday life where an inclined plane is used to reduce the effort force needed to accomplish a task.


Question 1: After completing this experiment, was your hypothesis supported? Explain why or why not.

^Experiment^ In this experiment, you will determine the IMA, AMA, and efficiency for the simple machine, the inclined plane.

The materials for this experiment are:

a smooth board
smooth block or other object to drag up a plane
a spring scale (calibrated in newtons)
string
books or blocks to support the inclined plane
and a meter stick.

Your job is to observe the experiment and collect your own data from this demonstration. Be ready to record your observations and data.

You will be pulling an object up an inclined plane at different inclines.
Make and record a hypothesis about how changine the slope of inclined plane will affect the efficiency.
Measure the height and length of the plane, record the measurements.
Measure the mass of the object, and record.
Convert the mass from grams to newtons by dividing by 102, and record.

Now slowly and steadily pull the object up the incline with the spring scale and string kept parallel to the incline.
Record the readout on the scale. This will be the effort force.

Now increase the slope of the incline by increasing the height.
Measure the height of the new incline. The length of the incline remains constant.
Slowly and steadily pull the object up the incline, record the readout from the scale.

Now increase the slope of the incline by increasing the height.
Measure the height of the new incline. The length of the incline remains constant.
Slowly and steadily pull the object up the incline, record the readout from the scale.

Now increase the slope of the incline by increasing the height.
Measure the height of the new incline. The length of the incline remains constant.
Slowly and steadily pull the object up the incline, record the readout from the scale.

Question 2: How does the length to height ratio (the IMA) of trial 1 compare to trial 2?
Why is the actual mechanical advantage less than the ideal mechanical advantage in each of the trials?
If a machine was 100% efficient, how would the AMA compare to the IMA?

Order the terms according to the path followed by oxygen during cellular respiration.

Answers

Order the terms according to the path

The respiration which is seen in plants and higher animals including humans take place in the presence of oxygen.

What is respiration?

The process in which the cells of an organism obtain energy by the combination of oxygen and glucose and results in the release of carbon dioxide, water and ATP (energy) is defined as the respiration.

In respiration, the transfer of oxygen occurs from outside environment to cells within the tissues. It is a biological reaction which takes place inside the cells of living organisms. The energy molecule ATP ( Adenosine triphosphate) is created during this process.

The ATP molecule produced here by the breakdown of glucose is utilized by the cells to perform various activities. The first step in cellular respiration is glycolysis which occurs in cytoplasm.

The correct path of oxygen transfer is:

Nostrils → Nasal cavity → Pharynx → Trachea → Bronchi → Bronchiole → Alveoli

either gained or lost an electron

Answers

Answer:

D

Explanation:

An ion is created because an atom doesn't have a balanced number of protons and electrons. A positive ion is created by an atom losing an electron and a negative ion is created by an atom gaining an electron.

The answer is D. What makes a neutral atom neutral is that it has an even number of protons and neutrons. If the number of protons and neutrons are unbalanced, it is now an ion.

After Eris was discovered, scientists had to decide whether to count it as a planet. Why did this make them question whether Pluto should still be counted as a planet?
a
because Pluto and Eris are both space objects
b
because Pluto and Eris were discovered at the same time
c
because Pluto and Eris are very different
d
because Pluto and Eris are very similar

Answers

Answer:

After Eris was discovered, they had to decide whether Eris was a planet or not. If they decided it wasn't a planet, they had to also decide whether Pluto should be counted as a planet since Eris and Pluto were quite similar. They were the same size, and they were both part of the Kuiper Belt.

Explanation:

Planets are the celestial bodies that are not fixed. Pluto should be counted as a planet was a question as both Pluto and Eris were similar.

What are Pluto and Eris?

Pluto is now considered a dwarf planet and is found in the Kuiper belt that is present beyond the planet, Neptune. Similarly, Eris is also a dwarf planet.

Eris is the second-largest dwarf planet and is very similar to Pluto. The discovery of Eris questioned whether Pluto should be considered a planet.

Both the planets Pluto and Eris were similar in size and were part of the Kuiper Belt leading to the question of whether they should be a planet or not.

Therefore, option d. Pluto and Eris are very similar.
