A scientist hypothesized that oxygen atoms from both carbon dioxide and water are used to make glucose during photosynthesis. However, experimental results using oxygen isotopes showed that all of the oxygen from the water ended up in the oxygen molecules that were produced. None of the oxygen from water was found in glucose.

What should the scientist do to best gain scientific understanding of this topic?

a. Analyze the results, and change the experimental methods to retest the hypotheses in a different way.
b. Discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods.
c. Analyze the procedural errors that took place in the experiment, and summarize these in a conclusion statement.
d. Repeat the experiment and adjust new data to support the original hypothesis.

Answers

Answer 1

The scientist Discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods; option B.

What is an experiment?

An experiment is a research or test conducted in order to prove or disprove a hypothesis.

An experiment is conducted using steps or procedures based on an explanation given to an observation.

The results of the experiment by the scientist disproved his hypothesis.

Therefore, the scientist should discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods.

What is oxygen ?

Oxygen is the chemical element with the symbol O and atomic number  It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O

Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.

Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as a component of water, the major constituent of lifeforms. Oxygen is continuously replenished in Earth's atmosphere by photosynthesis, which uses the energy of sunlight to produce oxygen from water and carbon dioxide. Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms.

Explanation:

Appropriate Question:-

The output for a 60kg woman who runs up a 3m high flight of stairs in 3.5 sec.starting from rest but having a final speed of 2 m/s.

Given:-

Mass of woman=m=60kg.

Height=h=3m

Time=t=3.5secs.

To find :-

Here we want to calculate the output for a woman

Here first we should calculate work done first.

work \: done = mghworkdone=mgh

Applying the values,

work \: done = 10 \times 60 \times 3workdone=10×60×3

Work done= 1800Joule.

Now , lets calculate power,

power = \frac{workdone}{time \: taken} power=

timetaken

workdone

Now,

Applying the values ,

power = \frac{1800}{3.5} power=

3.5

A. incrpreting it
B. plotting it on a graph to find correlations
C. analyzing it with statistical analysis
D. altering it to fit within the hypothesis

Answers

Answer:

D. altering it to fit within the hypothesis

Explanation:

An experiment is carried out to fill an inquisition i.e. to answer a question. According to the scientific method, prior to experimentation, there must be a HYPOTHESIS. The hypothesis is tested for rejection or approval via experimentation.

After the experiment has been conducted, several things can be done with the data obtained. For example:

- Data can be interpreted

- the data can be plotted in a graph to find correlations

- It can be analyzed it with statistical analysis.

One thing that should never be done is; altering the data from experimentation to fit in the hypothesis.

What conditions need to be present for an atom to form hydrogen bonds?

Answers

fluorine, oxygen, or nitrogen. These three elements are so electronegative that they withdraw the majority of the electron density in the covalent bond with hydrogen, leaving the H atom very electron-deficient.

For an atom to form hydrogen bonds, it needs to be bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) and have a hydrogen atom attached to it.

Hydrogen bonds are intermolecular forces that occur between a hydrogen atom bonded to a highly electronegative atom and another electronegative atom nearby. The highly electronegative atom, often nitrogen (N), oxygen (O), or fluorine (F), attracts the shared electrons in the covalent bond towards itself, creating a partial negative charge. This leaves the hydrogen atom with a partial positive charge.

The conditions necessary for hydrogen bonding to occur are:

Presence of a Hydrogen Atom: There must be a hydrogen atom (H) bonded to an electronegative atom (N, O, or F) in the molecule or adjacent molecules.Highly Electronegative Atom: The electronegative atom (N, O, or F) must have a strong attraction for electrons, creating a significant partial negative charge.Close Proximity: The electronegative atom with the partial negative charge must be close enough to another electronegative atom in another molecule or nearby region to allow for electrostatic attraction.

These conditions are essential for the formation of hydrogen bonds. The hydrogen bond itself is a relatively weak force compared to covalent or ionic bonds, but it is significant in biological systems and plays a crucial role in many biological processes. Hydrogen bonding contributes to the unique properties of water, the stability of protein structures, the binding of DNA strands, and various other molecular interactions.

In summary, for an atom to form hydrogen bonds, it must be bonded to a highly electronegative atom (N, O, or F) and have a hydrogen atom attached to it, with another electronegative atom in close proximity to allow for the formation of electrostatic interactions.

The displacement of the object is 303.75m.

What is displacement?

Distance covered by a body in a particular direction is called displacement. To calculate displacement from a velocity-time graph, we calculate the area under the curve.

The displacement is covered by drawing perpendiculars on the time axis. Let AB be the first and CD be the second perpendicular.

Extend A to CD at E.

Now, area of ABCD trapezium

= (AB + DC)/ 2 × AD

= (10.5 + 30)/2 m/s × 15 s

= 303.75 m is the area under the curve.

Therefore, 303.75 m is the displacement of the object.
