Salinity in an estuary varies according to one's location in the estuary, the daily tides, and the volume of fresh water flowing into the estuary. In estuaries, salinity levels are generally highest near the mouth of a river where the ocean water enters, and lowest upstream where freshwater flows in.

Explanation:

Answer:

An estuary can be defined as partially enclosed coastal body of the brackish water in which one or more than one  rivers flows into it.

It basically forms a transition zone between the river and maritime environments which is known as ecotone.

The salinity of the estuary depends on the location of the estuary. Salinity level in the estuary declines during the spring season and when the snow melts and the rain increases.

The level of the salinity increases during the time of summer because the level of evaporation increases.

Answer:

Decayed organisms are compressed underground

Explanation:

Fossils are the remains of organisms that are buried in a rock during sediment deposition over long geological time period. Since the bodies of these organisms is made of organic compounds, the high pressure of the overlying rock turns them into the hydrocarbons or fossil fuels. Therefore, option D is correct.

Answer:

...which are identical to the original parental DNA molecule.

Explanation:

Before a cell will divide the DNA it contains must first replicate to ensure that the resulting cells from the division will contain the same DNA for it to function similarly as well. Replication of DNA is a semi-conservative because the resulting DNA molecule will be half old or half new, where one strand is from the parent DNA and the other is a newly formed strand.

The newly formed strand of each side will be identical to the former complementary strand before it unzipped.

The replication of DNA results in two identical copies of the original DNA molecule, with each new DNA consisting of one original and one new strand, known as semiconservative replication.

The result of the replication of a DNA molecule results in two identical copies of DNA which are identical to the original parental DNA molecule. This process is known as semiconservative replication, meaning that each of the newly formed DNA molecules will consist of one strand from the original molecule and one new strand.

During DNA replication, each strand of the original DNA's double helix is used as a template for the construction of a complementary strand, leading to two DNA molecules that are identical to the original parent molecule.

The word would be used if the cell were from an animal is prokaryote which is the term used for an animal cell.

The prokaryotic cell has been defined as a cell which has one that lacks a true nucleus and membrane-bound organelles. The prokaryotic cell is the foundation of organisms in the domains Bacteria and Archaea.

In other hand the eukaryotic cells have a separate organelle named nucleus (plural: nuclei) which is a double membranous structure meant for the storage of genetic material i.e. chromosomes (DNA). Prokaryotes on the other hand have an irregularly shaped structure named nucleoid instead of nucleus.

All the genetic material of the prokaryotes is within the nucleoid. Unlike nucleus, nucleoid does not have any nuclear membrane & it is spread in the cytosol freely. Eukaryotic cells have nuclei but prokaryotic cells do not have nuclei.

Exothermic reactions release heat, as seen in combustion processes, while endothermic reactions absorb heat, as seen in the reaction in cold packs. Even exothermic reactions, however, require a small amount of initial energy input, known as the activation energy. The strength or weakness of bonds in the reactants and products also influences whether a reaction is exothermic or endothermic.

Endothermic and exothermic reactions differ in terms of heat absorption and release. An exothermic reaction is a process that releases heat. An example of this is the combustion reaction that occurs when using an oxyacetylene torch; this process releases energy in the form of both heat and light.

On the other hand, an endothermic reaction is a process that absorbs heat. An example is the reaction that occurs in a cold pack, used for treating muscle strains. When water and salt like ammonium nitrate in the pack are combined, the mixture absorbs heat, resulting in a sensation of cold.

It's also important to note that even exothermic reactions require a small amount of energy input to initiate, known as the activation energy. In terms of bond energies, exothermic reactions result when the bonds in the products are stronger than those in the reactants. Conversely, endothermic reactions occur when the bonds in the products are weaker than those in the reactants.

Answer:

RNA interference is the process of silencing the specific sequences of mRNA through siRNA. RNA interference process can be used to treat many diseases.

Treating asthma is the new approach to treat it through gene silencing as some genes are responsible for causing inflammation and swelling of the airways or respiratory tract.

RNAi to treat the diseases are very specific as the siRNA forms RISC which binds to the mRNA to slice the gene and deactivate the functioning of the gene.

RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression, typically by causing the degradation of specific mRNA molecules.

Here's how RNAi could potentially be used as a treatment for asthma:

1. Identification of Target Genes: The first step would be to identify the genes that are responsible for the inflammation in the airways of asthma patients. These genes code for proteins that may contribute to the inflammatory response.

2. Design of Small Interfering RNA (siRNA): Once the target genes are identified, small interfering RNA (siRNA) molecules can be designed. These siRNAs are complementary to the mRNA sequences of the target genes.

3. Introduction of siRNA: The siRNA is introduced into the cells of the patient's airways. This can be done using various delivery methods, such as viral vectors, lipid nanoparticles, or inhalation of siRNA formulations.

4. RNAi Mechanism: Inside the cell, the siRNA binds to the RNA-induced silencing complex (RISC). The RISC is guided by the siRNA to the target mRNA, leading to the cleavage and degradation of the mRNA by the Argonaute protein, a component of RISC.

5. Gene Silencing: The degradation of the target mRNA prevents it from being translated into the corresponding protein, effectively silencing the gene. This reduces the production of the inflammatory proteins, which should decrease the inflammation in the airways.

6. Therapeutic Effect: With the reduction of inflammation, the airways become less swollen, and breathing becomes easier for the patient. This could potentially alleviate the symptoms of asthma and reduce the frequency or severity of asthma attacks.

7. Safety and Specificity: One of the advantages of RNAi is its high specificity, which reduces the likelihood of off-target effects. However, the safety and efficacy of this approach would need to be thoroughly evaluated through preclinical and clinical trials.

8. Duration of Treatment: The duration of the RNAi effect depends on the turnover rate of the target cells and the stability of the siRNA. Repeated administrations or sustained delivery systems may be required to maintain therapeutic effects.

In summary, RNA interference offers a potential therapeutic strategy for asthma by specifically targeting and silencing the genes responsible for airway inflammation. This could lead to a reduction in inflammation and an improvement in respiratory function for patients with asthma. However, the practical application of RNAi in treating asthma would require careful consideration of the delivery method, potential side effects, and long-term effectiveness.

Answer:

A. If populations can interbreed, they are considered one species.

Explanation:

The organisms of a species have the ability to interbreed with one another leading to the formation of an offspring. For speciation to occur, the organism have to get diverged and isolated.

In speciation, a hereditary species parts into at least two relative species that are hereditarily not quite the same as each other and can never again interbreed.

In Allopatric speciation, the species gets geographically parted from their parent and evolves accordingly while in sympatric speciation, evolution of species occur when it stays in the same place as their parent.

Explanation:

Gene therapy is intended to acquaint hereditary material into cells in order to compensate for faulty or mutated genes or to make a helpful protein.

On the off chance that a faulty gene makes a beneficial protein be flawed or missing, gene therapy might have the option to present a typical duplicate of the gene to reestablish the function of the protein.  

A gene that is embedded straightforwardly into a cell as a rule doesn't work. Rather, a bearer or carrier called as a vector is hereditary built to insert the desired gene.

Human population increased sharply during the Agricultural Revolution  because of improvements in farming techniques.

Answer: B. Agricultural Revolution

Explanation:

The Agricultural Revolution was a time of mechanical improvement and expanded harvest efficiency that happened during the eighteenth and mid nineteenth hundreds of years in Europe.

Each significant development in agribusiness has enabled worldwide populace to increment. Early ranchers could settle down to a relentless nourishment supply.

Water system, the capacity to clear enormous swaths of land for cultivating productively, and the advancement of homestead machines controlled by non-renewable energy sources enabled individuals to develop more nourishment and transport it to where it was required.

The following significant stage in the development of the human populace was the Industrial Revolution, which began in the late 1700s.

"The process that puts carbon dioxide back into the air, other than carbon respiration or the carbon cycle, is known as ""decomposition.""

Decomposition is the breakdown of organic matter by decomposers such as bacteria and fungi. As these organisms consume the dead plant and animal material, they respire, releasing carbon dioxide back into the atmosphere. This process is a critical component of the carbon cycle, as it returns nutrients, including carbon, to the soil and atmosphere, making them available for reuse by plants and other organisms.

 In the context of the carbon cycle, when plants and animals die, their bodies are broken down by decomposers. The carbon in their tissues, which was originally taken from the atmosphere through photosynthesis, is released back into the atmosphere as carbon dioxide during decomposition. This continuous cycling of carbon between the living and non-living components of the Earth is essential for maintaining the balance of carbon in our biosphere."
