The term "anthropology" literally means "the science of humanity." Many disciplines, from anatomists to historians to psychologists, could claim the same lofty title. However, there is something about the anthropological study of "everything human" that distinguishes anthropologists and, in my opinion, gives us the primary right to the phrase "we study people."

Applied anthropology is the application of the discipline to address academic research and facilitate change. This is also known as anthropological practice. Academic peers, on the other hand, is primarily concerned with teaching the subject of anthropology and contributing to the field's overall knowledge base.

From superior to inferior, the three midline arteries that come off the abdominal aorta and supply the abdominal organs are: Celiac trunk, Superior mesenteric artery and Inferior mesenteric artery.

The celiac trunk is the first branch of the abdominal aorta and supplies the foregut, including the stomach, duodenum, liver, pancreas, and spleen. The superior mesenteric artery supplies the midgut, including the jejunum, ileum, cecum, appendix, and part of the colon.

The inferior mesenteric artery supplies the hindgut, including the remaining part of the colon, rectum, and anus. These three arteries play a critical role in providing blood flow and nutrients to the various abdominal organs, and any disruption to blood flow through these arteries can result in serious health problems.

Nematocysts are stinging cells that can be found in the phylum Cnidaria. These specialized cells can capture prey and deter predators. The hydra and sea anemone are two cnidarian species that possess nematocysts. While the nematocysts of hydra and sea anemone share similarities, they have some key differences.Nematocysts of a hydraHydra is a freshwater cnidarian that has a tube-like body and is a simple polyp.

Hydra has three types of nematocysts: spirocysts, microbasic mastigophores, and atrichous isorhizas. Each of these nematocysts have specific functions. For example, spirocysts help in wrapping the prey while microbasic mastigophores help in penetrating the prey's skin.Nematocysts of a sea anemoneSea anemones are marine cnidarians that have a sessile polyp body. They have a different type of nematocyst, acrorhagi. Acrorhagi are elongated nematocysts present on the oral disc and tentacles of sea anemones.

These nematocysts contain toxic threads that can be used as a weapon to attack other cnidarians. In addition to acrorhagi, sea anemones also possess spirocysts, microbasic mastigophores, and atrichous isorhizas, like hydra.To summarize, the nematocysts of hydra and those of sea anemone have a similar structure, but sea anemones also possess elongated nematocysts called acrorhagi that can be used as a weapon.

From the options The Largest carbon reservoirs on earth is : ( A ) Limestone

The Largest carbon reservoirs on earth includes the Earth crust ,Oceans and fossil fuels. Limestone makes up about 15% of the earth's crust ( sedimentary ) therefore it is the largest carbon reservoir out of all the options given above.

Limestones are used as raw materials for the production of cement and other building/construction materials.

The Earth crust contains about 50,000,000 g/tons of Carbon in total while the oceans contain about 40,000 g/tons of carbon which is followed by Fossil fuels at 10,000 g/tons

The type of plasmid that is associated with bacterial conjugation is fertility plasmids (F). Fertility plasmids contain genes that enable the transfer of genetic material between bacteria through the process of conjugation.

Option b is correct.

This process involves the formation of a conjugation bridge between a donor and recipient bacterium, allowing for the transfer of the F plasmid and other genetic material. Resistance plasmids (R), virulence plasmids, and bacteriocin plasmids do not necessarily involve conjugation and are associated with other functions such as antibiotic resistance, pathogenicity, and bacterial competition, respectively.

The replication of the DNA template strand is the process by which a new DNA strand is synthesized based on the information carried by the template strand of the DNA molecule.

This process occurs during the S-phase of the cell cycle, where the DNA double helix is unwound and the two complementary strands are separated by the enzyme helicase.

During DNA replication, each separated template strand serves as a template for the synthesis of a new complementary strand by the enzyme DNA polymerase. The nucleotides that make up the new strand are added in a complementary fashion to the nucleotides of the template strand, based on the rules of base pairing (A with T, and C with G).

Once the new complementary strands have been synthesized, they form two identical copies of the original DNA molecule, with one original and one new strand in each of the resulting double helices. This process ensures the faithful transmission of genetic information from one generation of cells to the next.

Full Question: What is the replication of DNA template strand?

DNA replication is the process where a cell's DNA is copied. This is vital for biological inheritance. Each strand of original DNA serves as a template, pairing with its complementary base and thus creating an identical copy.

The DNA replication process involves the copying of the DNA within a cell. This process occurs in all living organisms and is the basis for biological inheritance. The DNA molecule is 'unzipped' and each strand of the original molecule serves as a template for the production of a complementary strand. A DNA strand is composed of a series of nucleotides, and in the replication process, each nucleotide is paired with its counterpart on the other strand (adenine with thymine, and guanine with cytosine), ultimately creating an exact copy of the original DNA molecule.

None: Only those mutations that occur in the germ line and result in gametes will have a chance of being passed on to progeny. An alteration in DNA that occurs after conception.

Somatic mutations can occur in any of the body's cells except germ cells (sperm and egg) and are therefore not passed on to children. These alterations can (but not always) cause cancer or other diseases. Mutations in somatic cells are called somatic mutations. Because they do not occur in the cells that give rise to gametes, the mutation is not transmitted to the next generation sexually. Human somatic cells have 46 chromosomes: 22 pairs and 2 sex chromosomes that may or may not form a pair. This is the 2n or diploid condition. Human gametes have 23 chromosomes, each of 23 unique chromosomes, one of which is a sex chromosome. Somatic cells are the cells in the body other than sperm and eggs (called germ cells). In humans, somatic cells are diploid, meaning they contain two sets of chromosomes, one inherited from each parent. Mutations in a somatic cell occur in somatic cells and are transmitted by mitosis, resulting in cancer. However, mutations in a gamete are passed on by meiosis, resulting in mutated offspring. A genetic mutation occurs during DNA replication, and chromosomal mutations occur during meiosis.

Migration and an aging population have had a significant impact on Australia and New Zealand's population patterns.

In both countries, immigration has been the main driver of population growth, with a high proportion of migrants coming from Asia and the Pacific. This has resulted in a more diverse population, with a significant increase in the number of people speaking languages other than English. Additionally, the aging population has put pressure on both countries' healthcare and social welfare systems. As people live longer, the demand for health and aged care services has increased, leading to significant challenges for policymakers. To address these challenges, both countries have implemented policies to encourage migration and to support an aging population, such as increasing the retirement age and investing in healthcare and social welfare programs.

It destroys harmful substances or worn-out cell parts is a cell organelle lysosome. it is present in the eukaryotic cell and helps the cell protect itself from the virus or other harmful molecules.

The lysosome that is present in the cell has maintained an acidic environment because of the active transport of hydrogen from the cytoplasm to the lysosome. Due to its acidic nature, it can degrade the harmful pathogens in the cells and also degrade worn out cells, such as old mitochondria, and in this way, the lysosome protects the cell.
