Is mass conserved in chemical reactions?
Answer:
Mass is not conserved in chemical reactions. ... This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass.
Explanation:
Answer:
Mass is not conserved in chemical reactions. The fundamental conservation law of the universe is the conservation of mass-energy. This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass. This is not some exotic process, but in fact happens every time there is a reaction. Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction.
What can be used to measure the rate of photosynthesis
Answer:
the answer it at the bottom
Explanation:
Uptake of CO2 by plants: Since CO2 is needed for photosynthesis, measuring how much of it is taken up by the plants gives us information on how much of photosynthesis is happening.
Release of O2: The amount of O2 produced during photosynthesis can be measured.

Muscles in the small intestine are _____.
smooth
striated
involuntary
voluntary
cardiac
Pls pick multiple
Answer:
smooth and involuntary
Two layers of smooth muscle form the small intestine. The outermost layer is the thin, longitudinal muscle that contracts, relaxes, shortens, and lengthens the gut allowing food to move in one direction. The innermost layer is a thicker, circular muscle.
Also smooth muscle is not under our control so is called involuntary

How do i know if its entering or leaving or neither just by the precentage?
Answer:
1. Shrink
2. Swell
3. Neither
Explanation:
The percentage of water indicates how pure the water is, i.e. how concentrated the molecules of water are.
The higher the percentage of water, the more water molecules there are in the space.
Water molecules move from a high concentration to a low concentration across a semi permeable membrane, by the process of osmosis.
In beaker 1, the water outside is 89%, and inside the bag is 92%. That means the water inside the bag is at a higher concentration than outside. That means water will leave the bag, moving from a high concentration to a lower concentration outside. The bag will shrink.
In beaker 2, the water outside is 97%, and inside is 92£%. That means the water inside the bag is a lower concentration than outside. That means water will enter the bag, moving from a higher concentration outside to a lower concentration outside. The bag will swell.
In beaker 3, the concentration of water inside and outside is the same. That means they are in an equilibrium (the movement is balanced) so neither will occur
Which statement describes the movement of water when a cell swells up and bursts due to osmosis?
Group of answer choices
The cell membrane used energy to move water into the cell through passive transport.
The cell membrane used energy to move water out of the cell through passive transport.
Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.
Water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.

DNA Polymerase makes a copying error in a gene and an additional base
gets put into that gene. Which of the following is the most reasonable
result? *
1. The codons on the mRNA transcript contain an extra base which causes the amino
acid chain to not make the desired protein.
2. This causes RNA polymerase to transcribe the gene backwards.
3. The causes RNA polymerase to not recognize the gene and therefore no transcription
takes place.
4. The RNA polymerase recognizes extra bases and won't transcribe them.
Answer:
1. The codons on the mRNA transcript contain an extra base which causes the amino
acid chain to not make the desired protein.
Explanation:
Then error will make it not to produce the required output

What two parts of a nucleotide do not change throughout the structure of DNA?
Answer:
The second portion of the nucleotide is the sugar. Regardless of the nucleotide, the sugar is always the same. The difference is between DNA and RNA.
Explanation:
thanks me and follow me
Five-carbon sugar (deoxyribose sugar) and phosphate moiety are the two parts of a nucleotide which do not change throughout the structure of DNA.
What are Nucleotides?Nucleotides are the organic molecules which are consisting of a nucleoside molecule and a phosphate moiety. They serve as the monomeric units of the nucleic acid polymers- deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all the different life-forms on the Earth.
Nucleosides are made up of nitrogenous bases and pentose sugar. There are changes at the nitrogenous bases in the different nucleoside molecules however, there are no changes in the pentose sugar and the phosphate moiety of the molecule.

It takes place when magma introduces
great amount of heat into an existing rock
resulting in the recrystallization and mineral
reaction in the rock.
Answer:
The correct answer is - contact metamorphism.
Explanation:
Contact metamorphism is one of the two metamorphism processes which takes place when the pre-existing rock is introduced to a great amount of heat which affects it by an intrusion of magma. It is known as a low pressurized, high-temperature type of metamorphism.
An example of this type of metamorphism which experiences recrystallization in the rock and forms a metamorphic marble that is formed by the recrystallization and mineral reaction of the limestone.
