What type of RNA carries the genetic information from the Nucleus to the Ribosome?
The mRNA (messenger RNA) is the special type of RNA that transports the genetic information to the ribosomes.
What is mRNA?The messenger RNA (mRNA) is a special type of mRNA used to synthesize proteins by transcription and translation.
During gene transcription, a gene is used as a template strand and thus generates an mRNA.Subsequently, the mRNA molecule travels to the ribosomes where it will be used for protein synthesis.In conclusion, the mRNA (messenger RNA) is the RNA that transports the genetic information to the ribosomes.

Changes in the independent variable leads to changes in the dependent variable during an experiment.
Dependent and independent variableThe question is incomplete but I will try to help you as much as I can. An independent variable is one that is being manipulated in the experiment. The dependent variable is the variable whose outcome is determined each time.
Hence changes in the independent variable leads to changes in the dependent variable during an experiment.

How deep is the root system of a giant sequoia ?
Answer:
6-12 feet
Explanation:
The sequoia redwood trees have a unique root system that is a marvel, compared to their mammoth size. Their roots are relatively shallow. There is no tap root to anchor them deep into the earth. The roots actually only go down 6-12 feet, and yet, these trees rarely fall over.

explain the sequence of events in the replication of DNA
Explanation:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
How is DNA replicated?:
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.
What triggers replication?
A schematic shows a double-stranded DNA molecule undergoing the replication process. The left side of the molecule is double-stranded. In the middle of the molecule, a globular yellow structure, representing the protein helicase, is bound to the ends of several nitrogenous bases on the lower strand. To the right of the helicase protein, the double helix has opened and the top strand has separated from the bottom. At right, a short segment of the newly replicated double-stranded DNA molecule is visible.
Helicase (yellow) unwinds the double helix.
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains.
A schematic shows a double-stranded DNA molecule undergoing the replication process. At right, the double helix has opened and the top strand has separated from the bottom. A globular yellow structure, representing the protein helicase, is bound to the ends of several nitrogenous bases on the lower strand. A red globular molecule, representing the enzyme primase, is bound to the lower DNA strand to the right of helicase.
While helicase and the initiator protein (not shown) separate the two polynucleotide chains, primase (red) assembles a primer. This primer permits the next step in the replication process.
Meanwhile, as the helicase separates the strands, another enzyme called primase briefly attaches to each strand and assembles a foundation at which replication can begin. This foundation is a short stretch of nucleotides called a prime

Select the correct response regarding the relationship between photosynthesis and cellular respiration.
A. The products of cellular respiration are the products of photosynthesis
B. The reactants of photosynthesis are the reactants of cellular respiration
C. The reactants and products of photosynthesis has no relationship with the reactants and products of cellular respiration
D. The products of cellular respiration are the reactants of photosynthesis
Answer:
B is the answer
Explanation:
The correct response regarding the relationship between photosynthesis and cellular respiration is The reactants of photosynthesis are the reactants of cellular respiration. The correct option is B.
What is photosynthesis?
Photosynthesis is a process of transforming solar energy into chemical energy, which is then stored for later use. The majority of the time, this mechanism powers the planet's life systems.
The process by which sugar is broken down in the presence of oxygen in the cell to release energy in the form of ATP is known as cellular respiration. Water and carbon dioxide are waste products of this process.
So, photosynthesis is a process of anabolism process of food which produces energy, and for cellular respiration, glucose is combined with oxygen to form energy.
Thus, the correct option is B.

How does the carbon cycle support the Law of Conservation of Mass?
The carbon cycle supports the Law of Conservation of Mass, as the law states, the carbon also reuse and reabsorb in the carbon cycle.
What is the carbon cycle?
The carbon cycle is the movement of carbon from the atmosphere to plants and organisms. Carbon is coal when burned turn into gas.
The majority of carbon is kept in rocks and sediments; the remainder is kept in the ocean, atmosphere, and living things.
According to the Law of Conservation of Matter, matter can be created or destruct. Because the carbon cycle recycles the same carbon atoms, it serves as an illustration of the Law. Some carbon is stored for future growth, and some are used for energy.
Thus, because carbon is reused and reabsorbed in the carbon cycle, the Law of Conservation of Mass is supported by this law.

a) luster
b) cleavage
c) hardness
can someone plss help me??
Answer:
Luster
Explanation:
luster is the only answer that has to do with light. Luster is measured by the way a mineral reflects light.
Cleavage has to do with breaking minerals apart along certain fracture lines. Cleavage is not the answer.
Hardness is a test where one mineral is used to scratch another. The one that does the scratching is harder than the one that is scratched.
