Answer 1

A scientific theory is used to test a hypothesis. The correct option is A.

What is a scientific theory?

A scientific theory is an explanation of an aspect of the natural world and universe that has been repeatedly tested and corroborated using accepted protocols of observation, measurement, and result evaluation.

A scientific theory differs in that it is a broad general explanation that usually includes multiple hypotheses or observations.

A scientific model is used to test a scientific hypothesis or to represent a scientific theory.

Thus, it can be concluded that a hypothesis can be tested by scientific theory, means the correct option is A.

what is an expt in w/c extraneous variables have been controlled ​

Answers

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.

What do you mean by inhibition?

In psychology, inhibition is the conscious or unconscious restraint or restriction of a process or behavior, particularly of urges or wants. The ability to inhibit oneself from acting on some impulses, such as the desire to hit someone in a fit of rage, and the ability to postpone the enjoyment of enjoyable activities, all serve important social functions. Conscious inhibition occurs frequently in daily life and appears whenever two opposing urges are felt (e.g., the desire to eat a rich dessert versus the desire to lose weight).

According to psychoanalytic theory, inhibition serves as a mediator between the superego (the conscience) and the id (primitive desires). Taboos are socially imposed inhibitions that are raised to the level of prohibition, such as those against incest or murder of unwritten laws

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.

As a result of local tumor invasion, abnormal tumor vasculature, or tumor regression, bleeding may be brought on by the cancer itself. It might also be connected to previous chemotherapy or radiation therapy for cancer.

Numerous cellular organelles reside in the cytoplasm of cells. Cytoplasm is a semifluid substance of the cell.so, as a result cytoplasm helps in movement of the organelles inside the cell.

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?

Answers

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.
