General transcription factors are highly specialized proteins that are required for RNA pol II activation.
What are general transcription factors?They are proteins also known as basal transcription factors that recognize specific DNA sequences in the regulatory region of all genes.
These are capable of interacting with the transcription pre-initiation complex to induce or inhibit the activity of the enzyme RNA polymerase II.
Therefore, we can conclude that the general transcription factors are proteins that allow the assembly of RNA Polymerase II and the initiation of transcription.

does sunlight have a chemical compound?
Answer:
NO
Explanation:
Sunlight is an electro-magnetic wave not a substance therefore it does not have a chemical compound
Answer:
The Sun is composed primarily of the chemical elements hydrogen and helium. At this time in the Sun's life, they account for 74.9% and 23.8% of the mass of the Sun in the photosphere, respectively.

What infornation would you need
to find a more precise age of
dinosaurs and plants?
Answer:
The most precise evidence for dinosaur fossils would be found within the fossils themselves. The evidence that has been gathered from these fossils includes soft tissues, red blood cells, collagen, and even DNA fragments. Additionally dinosaur fossils have been found to be rich in carbon 14. This radioactive substance has a half-life of 5730 years. It seems that the evidence equates to dinosaur fossils being less than 50,000 years old.
Explanation:
The information that is needed to find a more precise age of dinosaurs and plants is relative geologic time.
What are dinosaurs?Dinosaurs are reptiles that were present 65 million years ago. They were very large, and they were both herbivores and carnivores. They laid eggs, and they are not present now. They got extinct. The plants and other animals present at that time were also extinct.
They are now found in fossils. Fossils are the remains of the bones and other things of plants and dinosaurs that are found inside the earth's crust.
These fossils have yielded evidence in the form of soft tissues, red blood cells, collagen, and even DNA fragments. Furthermore, it has been shown that dinosaur fossils contain a lot of carbon 14.
Thus, relative geologic time is the information needed.

Which of the following BEST explains why Earth is tectonically active?
Answer:C Earth's solid surface layer sits on a moving, semiliquid layer.
Explanation:
Earth is highly tectonically active because the solid layer of the earth sits on a moving, semi-liquid layer.
The earth's crust is broken into slabs. Together with part of the upper mantle, they form a layer called the lithosphere. These solid lithospheric bodies are called tectonic plates.
What information can you collect about the process that form copper across the world
Answer:
The high temperatures of volcanic magma creates hydrothermal veins, allowing some of the heat to escape near the upper layers of the Earth's crust. This is why copper is often found in the sedimentary layer, where sand and mud are compressed until they form a layer of sedimentary rock on the surface of the earth.
What does it mean that the cells are identical ? Please help
And also what’s the different between cytokines in a plant & animal cells
Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. ... Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
The key difference between plant and animal cytokinesis is that in plant cells, cytokinesis occurs through the formation of a cell plate while in animal cells cytokinesis occurs through the formation of a cleavage furrow.
Answer:
During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. ... In plant cells, a new cell wall must form between the daughter cells.

material from one cell to another.

Spindle fibers.
Explanation:
Hair like structure that attaches the cell to a surface and can transmit genetic material from one cell to another is called spindle fibers.
What are spindle fibers?In cell biology, the spindle apparatus refers to the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells.
The spindle apparatus is a structure of the eukaryotic cytoskeleton involved in mitosis and meiosis, often referred to as the mitotic spindle during mitosis and the meiotic spindle during meiosis.
Its function is to segregate chromosomes during cell division (either mitosis or meiosis) to the daughter cells. Spindle fibers that stretch from one pole to the kinetochore of chromosomes are called kinetochore fibers.

three dangers to mangroves
Answer:
Coastal Development. Coastal development may be the primary threat to mangroves. Not only are the forests lost when a coast is developed, but a man-made structure almost always replaces them.
Aquaculture, Agriculture & Salt Production. The close proximity of mangroves to the ocean makes them ideal locations for shrimp farming and other kinds of mariculture.
Deforestation. Most destructive uses of mangrove forests require their removal. The motivations behind deforestation include direct use of the mangrove wood and leaf products, or use of the wetland habitat.
Explanation:
Are personification and anthropomorphism the same?.

The correct answer is: A. the same traits
Homologous chromosomes come in pair: one inherited from the mother and one inherited from the father. They have the same genes in the same loci, meaning that those genes code for the same traits. But, variants of those genes-alleles can be different e.g. one recessive one dominant). During the meiosis (cell division of gametes) homologous chromosomes align correctly with each other before separation.

Why must DNA replication have to occur before a cell can divide by mitosis?
A. to cause one of the cells produced to have double the number of chromosomes as the parent cell
B. to allow crossing over to occur in each of the cells produced
C. to maintain the same number of chromosomes in the daughter cells as in the parent cell
D. to cause all of the cells produced to have half the number of chromosomes as the parent cell
Answer:
C
Explanation:
DNA replicates because the second set of DNA will move into the new cell during telophase. double-check in your text but C is the most accurate answer given. A doesn't happen unless there's a breakdown in cell division, and D is for meiosis when a diploid cell divides into a haploid cell. B could be correct but it's not entirely accurate.
