what is an expt in w/c extraneous variables have been controlled
Extraneous variables can threaten the internal validity of your study by providing alternative explanations for your results. In an experiment, you manipulate an independent variable to study its effects on a dependent variable.
When extraneous variables are uncontrolled, it’s hard to determine the exact effects of the independent variable on the dependent variable, because the effects of extraneous variables may mask them.
Controlling extraneous variables is an important aspect of experimental design. When you control an extraneous variable, you turn it into a control variable. Uncontrolled extraneous variables can also make it seem as though there is a true effect of the independent variable in an experiment when there’s actually none.
What is extraneous variables?
Any variable that you are not exploring in an experiment but that could potentially have an impact on the results of your research study is referred to as an extraneous variable.

Explain how the shape of incisors helps them to carry out their function?
Answer:
Your eight incisor teeth are located in the front part of your mouth. You have four of them in your upper jaw and four in your lower jaw.
Incisors are shaped like small chisels. They have sharp edges that help you bite into food. Whenever you sink your teeth into something, such as an apple, you use your incisor teeth.
Incisors are usually the first set of teeth to erupt, appearing at about 6 months old. The adult set grows in between the ages of 6 and 8.
Answer:
Incisors have a tiny chisel-like form. They feature pointed edges that make it easier to bite into food. You use your incisor teeth whenever you bite down on anything, like an apple.

What is ecosystem?An ecosystem is made up of all living things and their physical environment (or ecological system). These biotic and abiotic components are linked through nutrition cycles and energy exchanges. Photosynthesis takes place. Animals are essential for the movement of matter and energy because they eat both plants and other animals for nourishment. They have an effect on the biomass levels of both plants and microbes. Decomposers are creatures that decompose dead organic matter, releasing carbon into the atmosphere and promoting nutrient cycling by converting nutrients stored in decomposing biomass into forms that are readily used by plants and microbes.

Vaccination is a process of injecting a dead or weakened form of a pathogen into the body. How does this help strengthen the immune system?
Example: When you get the cold, your body inspects it. It realizes it hasn't seen that germ before, and responds by making special proteins to fight off the cold. This process isn't fast enough to stop the common cold, but it is fast enough to make you get well again.
Scenario: Next year, you get a vaccine for the stomach flu. You notice the doctor says to you that it injects the same germ into you. You ask why, and she responds that, "If we put this dead germ into you, then your body will recognize it. Just like it did when you got it last year. It will ahead of time make proteins to fight off the stomach flu. It will remember it forever." So when the stomach flu tries to sneak into your immune system, your body will already know how to fight it off-because the vaccine showed the body what the virus was, and what it was made of.
Apply: It's like a job interview. The vaccine is the person, presenting what they are and what they are capable of. The body is the boss, taking note of this. They will hire you--just like how the body lets it in. And turns out this job isn't for you. Similar to how the body will figure out the virus is foreign and bad. The boss will then know that people similar to you, wont work in this job field. Just like the body will make proteins and remember that that virus is bad.

Suppose that you are a scientist and you have been given a sample of unknown cells by looking at the cells under a microscope what would you be able to determine about the cells came from? explain your reasoning
If I were to look at the sample of the unknown cells under a microscope, I would be able to determine if the cells came from a plant or an animal by checking if the cells have a cell wall or not.
What is a cell?A cell is the smallest unit of life that is able to remain functional and live independently. A cell consists of a cytoplasm surrounded by a membrane. The cytoplasm contains various organelles that support life such as the nucleus, mitochondria and Golgi apparatus.
If one were to view a sample of unknown cells under a microscope, the best way to determine where it came from is to check if it has a cell wall or not. Cells with a cell wall are plant cells, and cells without a cell wall are animal cells.
The cell wall is a rigid structure found outside the cell membrane that provides additional chemical and mechanical protection for the cell. Animal cells have no cell walls, hence, are more flexible and take various shapes if viewed under a microscope.

blackburn's lab altered the sequence of the telomerase rna. predict what might happen to telomeres in tetrahymena cells if the tetrahymena template rna were mutated to 3'-accccgac-5'.
The telomeres sequence would altered to 5-GGGCTG-3 if the tetrahymena template rna were mutated to 3'-accccgac-5'.
The biological underpinning for limitless proliferative capacity is nearly always provided by telomerase, an RNA-dependent DNA polymerase that creates telomeric DNA sequences. The chromosomal termini of vertebrates are extended with lengthy, repeating lengths of the straightforward telomeric DNA sequence [TTAGGG]n by the specialized DNA polymerase known as telomerase. DNA replication is hampered by the ends. Because one of the two new DNA strands at a replication fork is continuously made and is referred to as the leading strand, the DNA at the very end of the chromosome cannot be fully copied in each round of replication. This results in a slow, gradual shortening of the chromosome. Each Okazaki fragment starts with its own RNA primer, and the other strand is created in a large number of little pieces. The second strand, also known as the lagging strand, is formed in several tiny fragments known as Okazaki fragments, each of which starts with a unique RNA primer.

In addition, arthropods are also characterized to have segmented bodies that may correspond to identical segments that may be different along their bodies.

DNA replication is semi-conservative and involves different enzymes in charge of unwinding the DNA molecule (topoisomerase), separating strands (helicase), creating primers (Primase), and adding complementary nucleotides (Polymerase). 1) DNA polymerase, 2) Topoisomerase, 3) Okazaki fragment, 4) DNA helicase, 5) RNA primase.
What is the DNA replication process?DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.
DNA Replication consists of the unwinding and opening of the double-stranded DNA molecule and producing two new molecules using these original strands.
DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one.
Initiation phase
Helicase and topoisomerase are the first enzymes involved.
Topoisomerase impedes the DNA double helix near the replication forks to get too coiled when the DNA is opening. This enzyme is necessary to release tension. Helicase works in the replication origin. It separates the original DNA molecule into two strands by breaking hydrogen bonds and separating the two original strands.Elongation phase
DNA polymerase, primase, and ligase act in this phase.
These enzymes are responsible for DNA elongation. They add nucleotides to the growing chain, from 3' to 5' extremes. The new chain grows in 5’-3’ direction.
Primase is in charge of synthesizing primers. Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment. DNA polymerase eliminate the primers and substitute them with DNA. This enzyme makes the new nucleotides enter the fork and pairs them with the corresponding nucleotide of the original strand.DNA ligase seals the gaps that remain after replacing the primers.DNA strands are antiparallel, and replication occurs only in 5'-3'direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.
The replication process results in two DNA molecules, each of them carrying an old strand and a new strand.
1) DNA polymerase
2) Topoisomerase
