Absence of oxygen means anaerobic respiration ; which has 2 different pathways.
First Pathway ; Alcoholic fermentation which takes place in yeast.
Pyruvate is decarboxylated into ethanal releasing co2 as waste product.
Ethanal is toxic , so its reduced by help of NADH to ethanol in presence of alcohol dehydrogenase enzyme , and Free NAD is released to continue glycolysis.
2) The second pathway is Lactic fermentation which takes place in mammalian muscles.
Pyruvate accepts hydrogen and is converted to lactate by the help of enzyme lactate dehydrogenase , again free NAD is released to continue glycolysis.
Hope I made it clear enough :)
Answer:
The dam,blocks off water from countine flow, and the result slows down the system
Explanation:
Answer is C; volume stays the same (always) but the shape will change (to take of the space of the container).
The correct order of steps in an experiment would be:
- Identify the variables.
- Write out your hypothesis in an if/then format.
- Gather your materials.
- Analyze the data.
- Write your conclusion.
<h3>What is an experiment?
</h3>
An experiment is a term to refer to the process by which a hypothesis is supported/disproved. The experiments serve to explain the cause-and-effect relationship according to the results obtained.
Experimentation has some important steps that we must follow to demonstrate our ideas regarding a scientific manifestation, these steps are:
- Identify the variables: We must identify the factors that we can manipulate so that the result changes.
- Write our hypothesis: Establish a hypothetical result that we are going to demonstrate.
- Gather the materials: We must have all the materials and variables to be able to carry out our experiments.
- Analyze the data: When we do an experiment we must record everything we see and then analyze it to examine each step and the procedures performed.
- Write the conclusion: After analyzing the data obtained, we can write a conclusion about the experiment carried out and the result obtained.

The surface temperature of white dwarf stars is higher than that of red super giants. White dwarf stars are extremely hot when they form, and they start cooling off as time goes by. Red supergiants, on the other hand, are enormous dying stars, and they are quite cool. So, having this in mind, white dwarves are hotter than red supergiants. Hope I helped! :) If it’s wrong then I’m sorry!
