Estuaries, aquatic biome, forms where freshwater streams or rivers merge with the ocean.
Estuaries are a transitionalzone between river environments and ocean environments.
They are impacted by both riverine and marine factors, including flows of freshwater and sediment as well as marine factors like tides, waves, and the inflow of salt water.
In addition to lagoons, river mouths, and tidal creeks, this wide definition encompasses them.
An estuary is a dynamic ecosystem that connects to the open sea and allows seawater to enter in accordance with the tide cycle. The fresh water flowing from rivers and streams dilutes the seawater that enters the estuary.
Therefore, where freshwater rivers meet saltwater seas is where estuary biomes typically occur.

Answer:Estuaries
Explanation:
Estuaries are areas where freshwater streams or rivers merge with the ocean. This mixing of waters with such different salt concentrations creates a very interesting and unique ecosystem
Answer:
The answer is mRNA
Explanation:
I took the test for connexus and tRNA was wrong
B. All of the cell's DNA attaches to proteins.
C. RNA attaches to DNA
D. The DNA folds over on itself to create a dense chromosome.
In DNA replication, the DNA unravels to make two strands.
DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the most essential part for biological inheritance.
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides.
Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits.

E. coli RNA polymerase is responsible for synthesizing the primary transcript for genes encoding enzymes involved in lactose metabolism.
These genes are located within the lac operon, which is 5,300 base pairs (bp) long. Given an average elongation rate of 70 nucleotides per second, we can determine how long it would take for the RNA polymerase to synthesize the primary transcript for the lacoperon.
To calculate the time required, we will divide the total length of the lac operon (5,300 bp) by the average elongation rate (70 nucleotides per second):
Time (seconds) = 5,300 bp / 70 nucleotides per second ≈ 75.71 seconds
Thus, it would take approximately 75.71 seconds for the E. coli RNA polymerase to synthesize the primary transcript for the lac operon at an average elongation rate of 70 nucleotides per second.

B) They must permit information transfer between the cell's cytoplasm and the nucleus.
C) They must provide a rigid structure that maintains an appropriate ratio of cell surface area to volume.
D) They are constructed of polymers that are synthesized in the cytoplasm and then transported out of the cell.
E) They are composed of a mixture of lipids and carbohydrates.
Answer:
D) They are constructed of polymers that are synthesized in the cytoplasm and then transported out of the cell.
Explanation:
Proteins, complex carbohydrates, lipids are important polymer components of the cell wall of bacteria, fungi, and extracellular matrix of animal cells. These all structures are located outside the plasma membrane but the raw material required to make these structures are synthesized inside the cell in the cytoplasm and exported outside the cell membrane by transporters.
Therefore cell walls of different organisms and extracellular matrix of animal cells are constructed of polymers that are produced in cytoplasm and are transported outside the membrane.
