uhhhhhhh erm have a good day is the answer yep mhm
Explanation:
A transcriptional activator is a protein (transcription factor) that increases transcription of a gene or set of genes. Activators are considered to have positive control over gene expression, as they function to promote gene transcription and, in some cases, are required for the transcription of genes to occur. Most activators are DNA-binding proteins that bind to enhancers or promoter-proximal elements.The DNA site bound by the activator is referred to as an "activator-binding site". The part of the activator that makes protein–protein interactions with the general transcription machinery is referred to as an "activating region" or "activation domain".
Most activators function by binding sequence-specifically to a regulatory DNA site located near a promoter and making protein–protein interactions with the general transcription machinery (RNA polymerase and general transcription factors), thereby facilitating the binding of the general transcription machinery to the promoter.Other activators help promote gene transcription by triggering RNA polymerase to release from the promoter and proceed along the DNA. At times, RNA polymerase can pause shortly after leaving the promoter; activators also function to allow these “stalled” RNA polymerases to continue transcription.
The activity of activators can be regulated. Some activators have an allosteric site and can only function when a certain molecule binds to this site, essentially turning the activator on Post-translational modifications to activators can also regulate activity, increasing or decreasing activity depending on the type of modification and activator being modified.
In some cells, usually eukaryotes, multiple activators can bind to the binding-site; these activators tend to bind cooperatively and interact synergistically.
Human papillomavirus (HPV), low socioeconomic level, smoking, marriage before the age of 18 years, young age at first coitus, several sexual partners, multiple sexual partners of spouse, and multiple childbirths are all established risk factors for developing cervical cancer. Because of hormonal changes or a compromised immune system, pregnant women may be more exposed to HPV infection or cancer.
Age may also play a role: Women who have their first child before the age of 20 are at a higher risk of cancer than those who wait until after the age of 25. Even if a person waits until marriage to engage in sexual activity or only has one partner.

I believe the above statement is false. Individuals diagnosed with a schizophrenic disorder do remain in treatment for long. Schizophrenia is a chronic brain disorder that affects about one percent of the population. When the disorder is active, symptoms can include delusions, hallucinations, trouble with thinking and concentration, and lack of motivation.
The rules of base pairing explain the phenomenon that whatever the amount of adenine (A) in the DNA of an organism, the amount of thymine (T) is the same (Chargaff's rule). Similarly, whatever the amount of guanine (G), the amount of cytosine (C) is the same.
Well, in the U.S textbooks, we use a system of 6 kingoms while in other textbooks like Great Britain, they have 5. (Britain isn't the only place with 5)
