When fossil fuels like coal and oil are burned, a greater amount of the carbon cycle is released into the atmosphere. As we burn trees to clear forests, more carbon is released into the sky.
What is the carbon cycle?Nature uses the carbon cycle to recycle the carbonyl group that continually flow from the air into Earth's living organisms and out again. Carbon is primarily stored in sedimentary deposits, with the remainder amounts being stored inside the ocean, air, and living things.
Why is the carbon cycle important?Because nature tends to keep carbon levels in balance, the carbon content that is naturally released from reservoirs equals the amount that's also naturally absorbed by reservoirs. By maintaining that biogeochemical cycles, the earth can support life indefinitely.

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.

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.

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

ANSWER is c
The rabbit population shown in the graph could have increased less in the third year than in the previous two years due to habitat loss through urban sprawl.
What is habitat loss?In ecology, habitat loss refers to the loss of the habitats of living organisms. The loss could be due to natural disasters or anthropological activities.
When the population of organisms of a particular species experiences habitat loss, it automatically results in a loss to some parts of the population.
In other words, habitat loss causes a decline in the population of organisms.
In the graph, the rabbit population experienced almost equal growth in the first and second years. The growth experienced in the third year, however, is not as big as in the first two years.

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.

2) Topoisomerase
