D. These show where thermal energy does not exist.
Answer:
B, they are changes of state.
The best interpretation of the two flat portions of the graph where these shows that change of state are occurring. Thus, C is correct option.
What are change of state?A state is physical condition of any substances it means that any substance which found on earth are mainly found in three states and these are following:-
1- Solid
2- Liquid
3- Gas
A change of state is physical change of state i.e any substance which changes their state from ( solid to liquid called melting), (liquid to gas called evaporation), (gas to solid called diffusion) etc are called change of state.
These change of state occurs when temperatures or pressure changes in a system or substances. When the temperature or pressure increase the interaction between the molecules also increases.
Therefore,the best interpretation of the two flat portions of the graph where these shows that change of state are occurring. Thus, C is correct option.

What is a benefit of a plant having Chlorophyll and Carotenoids?
A. The plant can absorb energy from multiple wavelengths at once.
B. They can absorb both sunlight and moonlight .
C. It is not a benefit.
D. If one becomes damaged, the other can take over.
Answer:
a
Explanation:
Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not green. Because green is reflected or transmitted, chlorophyll appears green. Carotenoids absorb in the short-wavelength blue region, and reflect the longer yellow, red, and orange wavelengths.
As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.

A population of birds can have large, heavy beaks or thin, long beaks.
What can we say based on this data?
Select one:
We cannot conclude anything without having more data.
Having heavier beaks is a survival advantage.
Having longer beaks is a slight survival advantage, but having more data would help to confirm.
undo
There is no survival advantage between having heavier beaks and longer beaks.
Answer:
We cannot conclude anything without having more data.
Explanation:
All the statement says it that the birds have different types of beaks. There is no mention of information that the beak difference brings advantage or not. If the question were to say the heavy beaks survive more, then the answer would be those birds have an advantage- because it does not, the answer is we need more data

There have been several mass extinctions in the planet's history, such as the extinction of the dinosaurs, but the current mass extinction is different. Greater numbers of species are now going extinct faster than ever before. Also unique to the current mass extinction is the cause. What is causing the current mass extinction
Answer:
There are several actions that not only humans have done to cause mass extinction. There are things such as poaching which is simply killing large and rare animals for horns, fur, meat, tusks, etc. These parts can be sold for money or resources. When one type of animal has characteristics of parts that give the poacher lots of wealth, herds or single animals can be tracked down and killed. The number of these animals dwindle down, and if nothing is done to help the animal, it goes extinct.
But things such as nature itself that can cause extinction where humans can do nothing about. For instance, a frog species called "Splendid Poison Frog " has gone extinct for a certain type of fungus that wiped the entire species out, where we can't do anything about.
There are many results on mass extinction, but these two are some that are caused.

Glycolysis and gluconeogenesis are opposing pathways in that they begin or end with the same metabolites and share common intermediates and/or enzymes. Yet, for energetic reasons, the two processes cannot be the exact reverse of each other. How is this possible
Answer:
Due to difference in their products.
Explanation:
Glycolysis and gluconeogenesis are not exact reverse to each other because in glycolysis, glucose is converted into pyruvate, adenosine triphosphate (ATP), NADH, protons i.e. hydrogen ions and water whereas in gluconeogenesis, pyruvate is converted into glucose and glycogen. So due to the formation of different products of each process we can say that glycolysis is not exact reverse of gluconeogenesis.
Select all that apply.

A microbiologist is characterizing a newly discovered microorganism that requires an anaerobic environment to live and uses either lactic acid or alcoholic fermentation in its energy metabolism. Which would be a way to determine the type of fermentation the microorganism uses
Answer:
The correct answer is - Analyze whether one molecule of CO2 is released for every one molecule of glucose fermented
Explanation:
Fermentation can be described as the process that breaks down the glucose-like molecules in absence of oxygen or anaerobically. There are different types of fermentation depending on the items they produce in used those products. The three types of fermentation are Lactic acid fermentation, alcoholic fermentation, and acetic acid fermentation.
One can determine the type of fermentation by analyzing the products they produced and the amount of carbon dioxide they produce for every one molecule of glucose fermented as lactic acid fermentation do not produce carbon dioxide whereas alcoholic fermentation produces two moles of CO2 per mole of glucose.
