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.
Adult hyrdras are _________, meaning they do not move.
Which statement regarding the relative ages of rocks and events is
accurate? *
A. Intrusive rock is older than the surrounding rock layers.
B. A fold is older than the oldest rock layer it contains.
C. Faults are younger than the youngest layer they cut through.
D. Rock layers that have been overturned are oldest from the base to the surface.
Answer:
C. Faults are younger than the youngest layer they cut through.
Explanation:
A. Intrusive rock is older than the surrounding rock layers. WRONG. The intrusive rocks are those that solidify underground and always form after the ones around them. So they are younger than the surrounding rocks.
B. A fold is older than the oldest rock layer it contains. WRONG. First, layers are set, and then, it occurs the folding. The folding is always younger than the involved layers.
C. Faults are younger than the youngest layer they cut through. RIGHT. A fault is a cut through different layers that occurs when the sedimentary rock breaks transversally. It occurs always after the sedimentary rock is already formed. So the fault is always younger than all the layers it cuts through.
D. Rock layers that have been overturned are oldest from the base to the surface. WRONG. If overturned, according to the superposition low, layers are oldest from the surface to the base. Superposition law states that during the sedimentary rock formation, the oldest layer is always that one at the bottom, while the younger layer is the higher one.

Explanation:
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.

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.

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

when people take a mineral and hold it up, what kind of test is that?
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.
