Answer:
1.) RNA polymerase find promotor
2.) RNA polymerase unwinds strand
3.) RNA polymerase adds new nucleotides
4.) RNA polymerase reaches termination site
5.) Transcript is released
The correct order is 1. RNA polymerase unwinds the strand, 2. RNA polymerase finds promoter, 3. RNA polymerase adds new nucleotides, 4. The transcript is released, 5. RNA polymerase reaches the termination site.
The process of transcription involves the synthesis of RNA from a DNA template.
RNA polymerase unwinds strand: RNA polymerase recognizes the DNA strand that needs to be transcribed and unwinds the double helix, separating the two DNA strands.
RNA polymerase finds promoter: RNA polymerase searches for and binds to a specific DNA sequence called the promoter, which marks the starting point for transcription.
RNA polymerase adds new nucleotides: Once bound to the promoter, RNA polymerase begins moving along the DNA strand, reading the template strand and adding complementary RNA nucleotides. This process is known as elongation.
The transcript is released: As RNA polymerase moves along the DNA template, it continues adding nucleotides to the growing RNA molecule. Eventually, it reaches a termination site on the DNA, signaling the end of the gene or region being transcribed. At this point, the RNA polymerase releases the completed RNA transcript.
RNA polymerase reaches the termination site: The termination site is a specific DNA sequence that signals the end of transcription. Once RNA polymerase reaches this site, it detaches from the DNA template, and the RNA transcript is released.
Thus, the correct order is 1. RNA polymerase unwinds the strand, 2. RNA polymerase finds promoter, 3. RNA polymerase adds new nucleotides, 4. The transcript is released, 5. RNA polymerase reaches the termination site.

The major pathway of communication between the right and left hemispheres is the.
Answer:
corpus callosum.
..............
Answer:
Corpus callosum
Explanation:
Actually, the left and right brain hemispheres may communicate with one another because to a thick bundle of nerves called the corpus callosum (Latin for "difficult body"). The corpus callosum, which is divided into several sub regions, connects various sections of the hemispheres. The corpus callosum is subdivided into the rostrum, genu, body, and splenium from anterior (front) to posterior (back). The brain's left and right frontal lobes are linked by the rostrum and genu. The hemispheres of the temporal and occipital lobes are connected by the body and spleen.
With over 200 million axons, the corpus callosum is the brain's biggest fiber bundle. It is made up of tracts of white matter fibers called commissural fibers. It has a role in several bodily processes, including the communication between the:
Cerebral hemispheres.Motion of the eye and vision.keeping the right balance of arousal and focus.The localization of touch.The different parts of our visual field, which independently process pictures in each hemisphere, are combined by the corpus callosum, which plays a crucial role in vision. By connecting the language centers of the brain with the visual cortex, it also enables us to recognize the objects we view. In order for humans to find touch, the corpus callosum also transmits tactile information—which is processed in the parietal lobes—between the two hemispheres of the brain.
what is the significance of diffusion and osmosis in living organism ?give one example in support of your answer
Answer:
Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).
Examples of where diffusion is important;
In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.
Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.
What is the relationship between the economy and the health of a marine ecosystem?
poor economic conditions increase demands for materials and harm the health of marine ecosystems.

1.What is one cost and benefits of double window glazing?
2.what is one cost and benefit of green roof?
( Science teachers if you see this please answer )
Explanation:
1.Warmer in the winter – Double glazing is great for insulation, it can also help capture natural heat and store it in the winter. This is a great way of keeping your home insulated in the winter months.
Energy cost savings – Less energy is used up to heat or cool a room when double glazed windows are installed, this results in lower energy bills and money being saved. Adding more layers of glazing will increase the insulation levels and save more money.
Cooler in the summer – Double glazed windows can trap some of the rays coming through the windows on a hot summer’s’ day causing your room to be cooler. This means less air-conditioning is required.
Safety – With more units being on double glazed windows, the safety of your home increases. They are harder to break and are sealed tighter than other windows.
Less condensation – Double glazed windows reduce the amount of moisture on your window panes, as the airtight seal prevents the condensation from building up. Other windows often allow condensation to build up which causes window panes to have mould in.
Less noise – With more units comes less noise and a quieter home. If you live by busy roads or in a generally noisy area then double glazed windows are crucial to you
