I really need help, thank you!
Answer:
Question 1. (C. Gravity) Question 2 (A. Stays the same) Question 3. (C. The Sun)
Explanation:
Question 2: I say this because it depends on where the planets are orbiting. Because planets closer to the sun will always have shorter years and and planets farther from the sun will always have longer years.
The other two question Im am 100% positive Im correct. So if someone knows Im correct or incorrect on question 2 please comment the answer below!

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.

Digestive and Excretory Lab Report
Procedure In your own words, summarize the steps you took to complete the lab. Explain what the test (independent) variable was, and what the outcome (dependent) variable was.
Answer:
The steps you took was to read the lesson, get the worksheet ready, complete the lab and while you are completing the lab in the lesson, record its data. Then answer the conclusion questions. Indepentent it like the cause and depentent is like effect so the independent is the sugary and non-sugary foods and the dependent is the blood glucose levels

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.

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.

Which primer would most likely cause the results in the gel shown below?
(Any STRs preset are highlighted in red on the images below.)
Answer:
Primer 2
Explanation:
The lanes on the gel are all smeared and there is no distinct band. This indicates that many DNA segments, all of different sizes, were created in the PCR process. If at least one primer is within an STR region, the primer can bind to more than one position along the region, resulting in segments of variable lengths. Of the four sets of primers shown, only the primers in image 2 are inside the STR region.

Does each daughter cell have the same genetic makeup as the original cell? Explain.
Answer:
Each daughter cell contains the same genetic makeup as the original parent cell
Explanation:
After the process of mitosis and cell division 2 new identical daughter cells are created. Each daughter cells contains the same number of chromosomes as the original cell. Therefore, each daughter cell has a complete copy of all the genes that the original cell contained. Making them identical to the original cell.

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
