The number of 5' ends would be Gap 1:6, Gap 2:12.
The carbon atoms in the sugar ring are numbered from 1' to 5', and the "5 prime end" of a nucleic acid strand has a free hydroxyl (or phosphate) on a 5' carbon and the "3 prime ends" has a free hydroxyl (or phosphate) on a 3' carbon. For a single-stranded (ss) DNA strand or an RNA strand, that is an easy enough task.
The pairing of the 5' end of one strand with the 3' end of the other strand in double-stranded (ds) DNA is not immediately apparent, however (it is "antiparallel"; ). If one strand is the sense strand of a gene. In that situation, the direction is determined by the sense strand's orientation.

How and why have humans modified the ecosystem in the everglades? what have the intended and unintended consequences been?
The humans modified the ecosystem within the everglades because US Army CORPS of engineers built a levee around Lake Okeechobee, which drained about 1/3 of the Everglades.
Reason :This then cause building canals, and more levees which then create more acreage to grow crops (such as sugarcane).If the wetlands suffer, so do humans will. Humans are a part of the Everglades ecosystem because they depend on it for survival. the shortage of biodiversity caused by invasive plant species, which is in a position to spread throughout new ecosystems, means humans may lose access to good jobs, and safe water supplies for drinking and farming.
Steps for improvement :So, humans are presumably working to improve the Everglades to protect their tourism industries and water supplies. it's intended to restore, protect, and preserve the Everglades by capturing freshwater that flows unaccustomed the ocean and the gulf, and redirect it to areas that require it most for environmental restoration. because the Everglades become a more livable environment, it'll be easier for species to recover or restore along with the land.

Why have more groups within the archaeplastids not developed complex multicellularity?.
More groups within the archaeplastids not developed complex multicellularity due to the fact that evolution is not goal-oriented, complex multicellularity has developed, and each group is successful with its current morphology.
Archaeplastids comprised of many more groups which have no developed multicellularity in complex structures. From fungus to people, every multicellular organism first evolved from a single cell. Before assembling to create multicellular groups, these cells were able to exist on their own for billions of years.
The majority of archaeplastids are single-celled algae. The name “archaeplastid” refers to early plastids. Given that they may have ingested cyanobacteria and acquired chloroplasts through endosymbiosis, this is supported by evolutionary evidence.
In the course of evolution, other eukaryotes may have swallowed up archaeplastids to acquire chloroplasts. Some of the members of this group later developed multicellularity. Therefore, it’s merely a random event that could proceed in any way. The only difference is that Archaeplastida evolved in accordance with their environment and demands.

Which population would be most likely to undergo relatively rapid allopatric speciation?
Allopatric speciation would be fastest in the herd of wild horses.
What is allopatric speciation?
When groups of a same species are geographically separated from one another, allopatric speciation takes place. Populations gradually change into new species through a process called speciation.
A herd of wild horses was shipped from Wyoming to a little desert island off the coast of California that had never before had any. After then, no more horses arrive at the island. The new population is tiny (reproductively) and geographically separated from neighboring populations, both of which tend to favor allopatric speciation.

Ways humans positive impact the nitrogen cycle
Humans positively impact the nitrogen cycle according to a recent study, humans are oversupplying ecosystems with nitrogen through the combustion of fossil fuels as well as an increase in industrial and agricultural activities that produce nitrogen. Although nitrogen is a necessary ingredient for life, it is a disaster for the ecosystem when present in large quantities.
The nitrogen cycle is the biogeochemical process through which nitrogen is changed into a variety of chemical forms as it moves across ecosystems in the atmosphere, on land, and in the sea. It is possible to convert nitrogen using both biological and physical methods.
The nitrogen cycle assists in introducing inert nitrogen from the air into plant and animal metabolic processes. The nitrogen cycle is crucial for plants because they need nitrogen to produce chlorophyll.
Because nitrogen is a necessary nutrient for supporting life on Earth, the nitrogen cycle is important. Amino acids, which are the building blocks of proteins, and nucleic acids, which are the building blocks of genetic material, both include a significant amount of nitrogen (RNA and DNA).

They are present in most biochemical and molecular processes, from transcription of genes in the cell nucleus to cell cycle regulation, and are heavily involved in physiological and behavioral mechanisms. The central circadian regulatory nucleus in mammals that responds to environmental light-dark cycles is known as the suprachiasmatic nucleus (SCN) and is located in the anterior hypothalamus of the brain. A set of clock genes form a transcription-translation feedback loop at the SCN, a key mechanism of circadian rhythms.

2. When the cap is attached, the cylinder transforms into a hydrophilic environment that facilitates the folding of the polypeptide.
3. The cap is removed, releasing the correctly folded protein.
What is Chaperone (protein)?In molecular biology, molecular chaperones are proteins that aid in the conformational folding or unfolding of large proteins or macromolecular protein complexes.The common goal of all the different molecular chaperone groups is to aid in the appropriate folding of large proteins during or after synthesis as well as during partial denaturation.Chaperones are also involved in protein translocation for proteolysis. The first molecular chaperones to be discovered are assembly-type chaperones that aid in the formation of nucleosomes from folded histones and DNA.One of the primary functions of molecular chaperones is to prevent the buildup of misfolded proteins since heat stress increases the tendency for protein aggregation.The majority of chaperone proteins are hence classified as heat shock proteins.To learn more about chaperone proteins, refer to the following link:
