How many electrons must get passed down the Electron Transport Chain before energy is generated?
Answers
Answer:
4 electrons
Explanation:
Electron transport chain is defined as the series of process in which electron transfer takes place across a membrane. It is consists of enzymes, peptides, and other molecules.
There are 4 electrons that passed down the Electron Transport Chain before energy is generated. These Four electrons further reduce each molecule of oxygen. Oxygen binds with free proton and form water and move across the membrane to form ATP.
Hence, the correct answer is "4 electrons".
Answer: 2

Cellular division (Mitosis) is the biological process whereby a parent cell breaks itself into different parts called daughter cells.
This process is important because it helps to divide cells so that they can:

D. wooden logs burning to form ash
E. hydrogen and oxygen forming water
Answers
Answer:
D and E
Explanation:
The others are physical methods and can be separated again.
Hope this helps :)
Ashes (which are made of carbon), carbon dioxide gas, water vapor, heat, and light are produced when wood is burned. Since this change cannot be undone, it is a chemical change. Since oxygen and hydrogen unite to create a single product, Thus option D and E is correct.
What is chemical changes?A chemical change is the transformation of one substance into another, the emergence of new compounds with distinct properties, or any combination of these.
It happens when two compounds mixes to create a new material (synthesis or either decomposes to form more substances).
Chemical synthesis, or, alternatively, chemical breakdown into two or more separate molecules, occurs when one material reacts with another to create a new substance.
These processes are referred to as chemical reactions, and they are typically irreversible barring additional chemical reactions.
Therefore, burning of wooden logs and formation of water is an example of chemical changes.

Independent Variable (IV): _Type of clock_____________________________________________ __________________________________________ Dependent Variable (DV): ______________________________________________ Control: _____________________________________________________________ Constants:____________________
Answers
Answer:
Independent variable: Type of battery
Dependent variable: Time the clock stopped
Control: None for this experiment
Constants: Same type of clock
Explanation:
Independent variable in an experiment refers to the variable which the experimenter changes or manipulates in order to bring about a measurable response. In this case, the independent variable is the TYPE OF BATTERY USED.
Dependent variable is the variable that responds to changes made to the independent variable. It is the measured variable in an experiment. In this case, the dependent variable is the TIME THE CLOCK STOPPED FOR EACH BATTERY
Control is the group that does not receive the experimental treatment. In this case, NO control group is USED.
Constant is the variable that the experimenter keeps unchanged throughout the experiment for all groups. The constant in this experiment is the CLOCK USED.
Answer:
Independent variable: Type of battery
Dependent variable: Time the clock stopped
Control: None for this experiment
Constants: Same type of clock

Each year, the United States' federal costs exceed the anticipated national budget. In fact the last time that the United States government was able to end a fiscal year without accruing more debt was in 1960. This means that due to excessive spending and compounding interest accrued, the United States' national debt has escalated astronomically over the past several decades. The table shown below lists the recorded U.S. national debt amounts, written in standard form, for each decade, from 1960 to the year 2010.
Year U.S. national debt (in U.S. dollars)
1960 $286,330,760,848.37
1970 $370,918,706,949.93
1980 $907,701,000,000.00
1990 $3,233,313,451,777.25
2000 $5,674,178,209,886.86
2010 $13,561,623,030,891.79
For each decade, convert the U.S. national debt amount to a number in scientific notation, rounded to the nearest hundred millions dollars. Enter in numerical answers only.
