If a scientific idea has been proven 100% of the time, like gravity, it becomes a whereas an idea that is generally believed but has not been proven to be 100% true would be called a .
Answer:
The correct answer would be - scientific theory.
Explanation:
A scientific theory is a confirmed explanation of any particular natural aspect or phenomenon of the world which is confirmed and accepted widely by the facts based on observation and experiment.
This particular idea or explanation for the natural phenomenon is true time based and believed to be true for time being and proved for a time but can be changed with the new discoveries and facts.
Answer:
For the first question if it were 100% law ........................................................................for second question if it is not 100% Theory
Explanation:
because if it were to be 100% true it would be a law but if it is not it is a theory is something that is most likely to be true. If it were a theory they would probably go on to study it more to.ps. I took this quiz and think I got the question right! GOOD LUCK!

What is the purpose of protein synthesis?
Answer:
Protein synthesis is the process all cells use to make proteins, which are responsible for all cell structure and function. There are two main steps to protein synthesis. In transcription, DNA is copied to mRNA, which is used as a template for the instructions to make protein.
Explanation:
Proteins are one of the most important biomolecules essential for the survival of organisms owing to the myriad of functions that they play in the physiological system.
Proteins that are ingested are easily degraded to amino acids or peptides by the action of HCl in stomach and the digestive enzymes present in the gastrointestinal tract. Thus, proteins have to be synthesized in the body to meet the body's needs for various functions.
Some of the functions of proteins include:
1. Enzymes are majorly proteinaceous in nature and are required for crucial functions, including cell division and DNA synthesis.
2. Motor proteins help in movement and also provide cytoskeletal structure to the body.
3. They are required for the functioning of the immune system.
4. Proteins are required for cell signaling pathways.

3. What would happen if all of the top-level consumers in the reef ecosystem died out?
Answer: Coral reefs provide protection against flooding and the erosion of coastlines. With them gone, there will be rapid erosion of coastlines and many small island countries might even vanish from the world map. There may be many more serious repercussions that we are unable to perceive at this moment.
Answer:
The reef would die.
Explanation:
After photosynthesis, energy that the coral can use is stored in
molecules of?
Answers:
O2
CO2
H2O
C6H12O6
Answer:
Energy is stored in glucose molecules C6H12O6
Explanation:
Producers make sugars stored as monomers bonded together to form polysaccharides, long chain hydrocarbon molecules as a result of the process of photosynthesis. These molecules, like the monosaccharide glucose, store converted solar energy as stable chemical energy in covalent bonds. In covalent bonding, the elements share electrons with each other.
These high-energy bonds are stable and not easily destabilized or broken. The energy is retrieved the the process of respiration in the mitochondria.
Glucose is broken down, while energy is transferred to bonds between ADP and inorganic phosphate, to produce ATP (adenosine triphosphate).
Eg. for aerobic respiration...
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy

READING TOOL Make Connections Fill in the concept map to show the
organization of a chloroplast. Then below, answer the questions to describe how the
different parts are related to each other.
Chloroplast
Answer:
Chloroplast -----membranes----------internal
---------external
----- Tylacoids-------------Grana
----- Stroma
You will find the complete concept map in the attached files
Explanation:
The chloroplasts are limited by two membranes, the internal and the external membranes. Both of them are separated by the intermembrane space.
In the interior of the organelle, thylakoids are composing the third system of membranes. In the interior of thylakoids, there is an additional compartment named thylakoid space. This membrane system forms piles, known as grana. Different grana structures connect to each other by a longer thylakoid membrane. The photosynthetic pigments are located in the thylakoids, where it occurs the light-dependent reactions.
Surrounding the thylakoids there is a dense liquid called the stroma. Here takes a place the Calvin cycle.
To fill in the diagram you will need to show the composition of the chloroplast. Therefore, you should show the internal and external membranes, the thylakoids, the grana, and the stroma.
We can arrive at this answer as follows:
Chloroplasts are organelles present in plant cells, they are very important in the photosynthetic process.Chloroplasts have two membranes, an internal and an external one, which limits the entry and exit of substances.Inside the chloroplasts are the thylakoids, which are formed by structures called grana, which form numerous piles, which resemble towers.The unoccupied space within the chloroplast is filled with a fluid called the stroma.In the figure below you can see how this diagram can be filled.

During the months of July, August, and September, when the squirrels are more active we would expect the artic squirrels:
A) To produce more O2 when compared to other months.
B) To have a higher output of CO2.
C) To produce less water.
D) Increase in the output of glucose.
Answer:
B) To have a higher output of CO2.
Explanation:
We would expect the artic squirrels to produce a higher output of CO₂. As with most heterotrophs, the by-product of their respiratory activities is the formation of carbon dioxide gas.
They use oxygen gas to break down glucose. The process releases energy for their life activities. The waste product is usually carbon dioxide which enters back into the ecosystem as a waste.BRAINLEST AND POINTS HELP ME OUT !!
