Answer:
False
Explanation:
In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.
There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.
Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.

The clade Ecdysozoa includes <u>8</u> phyla, of which you will be observing only two in this week's lab.
<h3>What is Ecdysozoa?</h3>
- Arthropoda (insects, chelicerata, crustaceans, and myriapods), Nematoda, and a few other minor phyla are all included in the group of protostome creatures known as Ecdysozoa (/kdsozo/).
- Aguinaldo etal. provided the initial definition of them in 1997, largely based on phylogenetic trees generated with the use of 18S ribosomal RNA genes.
- The Ecdysozoa were firmly supported as a clade in a sizable study conducted in 2008 by Dunn etal.
- A clade is a group made up of all the descendants of a common ancestor.
- All animals that grow by ecdysis, or moulting their cuticle, are included in this group, which is also supported by morphological characteristics.
<h3>What is phyla?</h3>
- A phylum is a taxonomic rank or degree of classification in biology that comes before a kingdom and after a class (/falm/; plural: phyla).
- Phylum and division are similar terms according to the International Code of Nomenclature for algae, fungus, and plants, but division has historically been used in botany instead of phylum.
- Depending on definitions, there are between 31 and 14 phyla in the plant kingdom Plantae, 8 phyla in the fungus kingdom Fungi, and roughly 31 phyla in the animal kingdom Animalia.
- The links between phyla, which are housed in more expansive clades like Ecdysozoa and Embryophyta, are currently being revealed via phylogenetic studies.

All of these choices challenge homeostasis
It helps homeostasis, by maintaining the shape of a cell depending on how much solute is outside of the cell and how much water is inside the cell, in an isotonic solution the size of the cell stays the same because the amount of water inside the cell is the exact same percentage of solute outside of the cell.
