Compare and contrast atoms and molecules. Cite specific examples from the readings, as well as what you may already know, to support your comparison.
Answer:
The main difference between an atom and a molecule lies in the size: while the atom is the smallest unit into which matter can be divided into any of its states, a molecule is the union of a group of atoms, that is, this composed of several atoms. Thus, for example, a water molecule is composed of two hydrogen atoms and one oxygen atom (H2O). Therefore, it can be said that atoms are the smallest unit in which the chemical elements of the world can be divided, while molecules are the particles of matter that are formed through the combination of these elements.

When scientists create a representation of a complex process, they are
inferring
c. classifying
b. predicting
d making models.
a.
Please select the best answer from the choices provided
А.
B
D
Answer:
d making models.
Explanation:
When scientists create a representation of a complex process, they are inferring that they are making models.
A model is an abstraction of the real world or a complex process. Models are very useful in developing solutions to processes that are not easily simplified.
The models allow a part of a body to be simply studied. Through this simple abstraction, extrapolations to other parts of the system can be deduced. This can give very useful insights into the other parts of the system. The heterogeneity of complex processes is a huge limitation to understanding them. A homogenous part can be modelled and used to understand the system.Answer:
D. making models.

What type of plate boundary (divergent, convergent, or transform) is typically
associated with sliding or shear forces?
convergent
transform
divergent
Answer:
transform
Explanation:
The type of plate boundary associated with sliding or shear forces is a transform plate boundary.
Two or more plates slides laterally past one another due to presence of shear forces acting on them.
In this margin, there is often an occurrence of earthquake. For a divergent margin, plates move apart and away from one another. This leads to the creation or formation of new crusts. At a convergent margin, two plates collides, a plate can subduct under another or both can become uplifted. Tectonic margins are known for their various activities.Answer:
convergent
Explanation:
In which type of reaction is ATP the driving force?
O
A. anabolism only

If you look at the periodic table today which elements would best represent a triad as predicted by Dobereiner?
A. Hydrogen Oxygen Nitrogen
B. Nickel Copper Zinc
C. Aluminum Gallium Indium
D. Neptunium Plutonium Americium
E. All of them are triads
HELP ME PLEASE!!!!
Answer: B. Nickel Copper Zinc
Explanation:
Dobereiner's triads was a group of three elements. Dobereiner said that the relative atomic mass of the middle element in each triad was average of the relative atomic masses of the other two elements.
Thus if A, B and C forms Dobereiner's triads, the mass of B is average of mass of A and C.
A. Hydrogen Oxygen Nitrogen:
mass of oxygen = 15.999
mass of oxygen according to Dobereiner = [tex]\frac{1.008+14.007}{2}=7.5075[/tex]
B. Nickel Copper Zinc
mass of copper = 63.5
mass of copper according to Dobereiner = [tex]\frac{58.7+65.38}{2}=62.04[/tex]
C. Aluminum Gallium Indium
mass of gallium = 69.72
mass of gallium according to Dobereiner = [tex]\frac{26.98+114.82}{2}=84.39[/tex]
D. Neptunium Plutonium Americium
mass of Plutonium = 244
mass of Plutonium according to Dobereiner = [tex]\frac{243+237.04}{2}=240.02[/tex]

a. UVC rays are deflected by earth's atmosphere; UVA and UVB rays aren't
b. UVC rays can penetrate all the layers of your skin; UVA and UVB rays don't
c. UVC rays contain very little energy; UVA and UVB rays are very powerful
d. Sunblock can protect you against UVC rays, but not UVA and UVB rays
Answer: A.. for sure
Explanation:
Photosynthesis requires light, water, and CO2 to work. When one of these factors is in short supply, it is called a limiting factor. Temperature can also be a limiting factor when it is too hot or too cold for photosynthesis to work well. If you are trying to grow plants in a greenhouse, why is it important to know the limiting factor?
A farmer can be more successful in understanding which plant produces and how to grow plants with a higher degree of photosynthesis with less material and time exhaustion, by recognizing what the limiting factor is.
Hope this helps! Please correct me if I'm wrong :)
These two finches share a common ancestor from South America. What is the most likely way that one ancestral finch species will develop into two distinct species?
A The ancestral species was genetically engineered to become two new species
B Groups of the ancestral species became isolated and adapted to different environments.
C. Two individual birds acquired many spontaneous mutations.
D. The ancestral species mated with other species and the offspring resulted in two new species.
Answer:
The correct answer is - B. Groups of the ancestral species became isolated and adapted to different environments.
Explanation:
Two finches Warbler Finch and Woodpecker Finch are two distinct finches are finches from the Galapagos Islands. Both of these finches have a common ancestor from South America.
The most likely explanation of developing two distinct species from an ancestral finch is by bein isolated and developed or adapted according to the challenges and environmental conditions and ultimately become different species after several generations.

Which characteristic do euglenoids and algae share?
Both are fungus-like protists.
Both can be autotrophic.
Both have whip-like tails.
Both are decomposers.
To solve this we must be knowing each and every concept related to autotroph. Therefore, eugenides and algae, both can be autotrophic. The correct option is option B.
What is autotroph?An creature that can make its own sustenance out of inorganic materials is known as an autotroph. Contrarily, heterotrophs are species that can't make their own nutrition and must eat other organisms in order to survive.
In contrast to autotrophs, heterotrophs are unable to manufacture their own nourishment. Heterotrophs need to consume organic material in order to produce the nutrients needed for life, not inorganic. Eugenides and algae, both can be autotrophic.
Therefore, Eugenides and algae, both can be autotrophic. The correct option is option B among all the given options.
