Answer:
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.
The new cells are identical copies

True.

Explanation:</h2>
Boyle's law was given by Robert Boyle in 1662.
Boyle's law was given for gases, this law states that the pressure (p) and volume (v) of a gas are inversely related to each other at constant temperature. Which means if the volume of the gas increases, then pressure decreases and vice versa, at constant temperature.
p ∝ 1/v .
Result: The given statement is true.
The answer is two.
About 90 percent of mother's milk is water. A baby drinks up to one liter of milk per day. The simple math says it is important for a mother to take almost one liter of water for the milk and one more for her body to be hydrated. This is 2 liters per day in total. Of course, the more is the better, so drinking up to 3 liters will help the mother to stay hydrated.
Answer:
The correct answer is the letter b. The endosymbiotic event that brought chloroplasts into Eukaryotic cells actually happened after Eukaryotic lineages diverged so many lineages never actually possessed chloroplasts
Explanation:
The plastid is an organelle linked to membarna found in the cells of eukaryotic organisms, which contains pigments used in photosynthesis. Some eukaryotic organisms over time have inherited the ability to photosynthesize from cyanobacteria by secondary endosymbiosis or ingestion, and are able to capture and sequester photosynthetic cells and chloroplasts, this process is known as kleptoplasty.
