Water is extremely important to the survival of all organisms found on Earth.
Water helps support life in many ways. These life providing properties of water
are all basically derived from water's ability to form Hydrogen bonds, as a result
of it being a polar molecule. Describe a typical Hydrogen bond between
Hydrogen and Oxygen.
Your answer
Answer:
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.
Explanation:
SO THE ANSWER IS (A): Water helps support life in many ways. These life providing properties of water.

if you start with one double-stranded dna molecule and you perform six cycles of pcr, how many double-stranded copies of the dna will you have?
Answer:64
Explanation:
The DNA stands for deoxyribose nucleic acid. The DNA has all the genetic information stored in it that will transfer to the next generation. The DNA is made from the following:-
Deoxy sugarPhosphate groupNitrogenous baseThe PCR stands for the polymerase chain reaction. This process its amplify the DNA content and multiply it. The PCR has three steps which are:-

Which of the following is not a lipid?
Asteroid
B cholesterol
C
wax
D cellulose
Answer:
cellulose
Explanation:
lipids are fats oils or waxes. cellulose is a fiber
Answer:
cellulose
Explanation:
Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein. Therefore waxes are not the answer.
Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts. Therefore steroid and cholesterol is not the answer.
How do hydrogen ions get transferred from the Light Reaction to the Calvin Cycle?
Answer:
A photon of light hits chlorophyll, causing an electron to be energized.
The free electron travels through the electron transport chain, and the energy of the electron is used to pump hydrogen ions into the thylakoid space, transferring the energy into the electrochemical gradient.

Which statement correctly demonstrates the relationship between cellular respiration and photosynthesis?
A: The ATP produced by all cells during cellular respiration can be used by plant cells to produce water molecules during photosynthes
B: The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
C: The oxygen produced by all cells during cellular respiration can be used by plant cells to produce glucose during photosynthesis.
D: The water molecules produced by plant cells during photosynthesis can be used by all cells to produce oxygen during cellular O respiration.
Answer:
your answer is B. The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

Explanation:
enzyme + substrate complex =
A substrate is a molecule that an enzyme reacts.
enzymes catalyze chem. reactions with substrates. Substrates transform into 1 or more products. released from " active site," substrate is then able 2 receive another substrate molecule.
Answer:
An enzyme is catalyzing a reaction.
Explanation:
Two substrates bind to the active site of the enzyme. The enzyme catalyzes the reaction (lowers the activation energy needed to complete the reaction), and the result is the final product: two substrates bound together, and an enzyme that can go on to catalyze more reactions.

Calculate the total resistance (in Ohms) of a light bulb marked 2V and 3A. Do not add units. Leave your answer as a decimal to 2 decimal places.
The total resistance of a light bulb marked 2V and 3A is 0.67ohms
HOW TO CALCULATE RESISTANCE:
The resistance of a substance can be calculated by using the formula as follows:R = V/I
Where;
R = resistance (in ohms)V = voltage (in volts)I = current (in amperes)According to this question, a light bulb is marked 2V and 3A. The resistance (R) can be calculated as follows:R = 2V ÷ 3A
R = 0.67ohms.
Therefore, the total resistance of a light bulb marked 2V and 3A is 0.67ohms.Learn more at: https://brainly.com/question/8776047?referrer=searchResults
