There are more than 30 known sexually transmitted infections (STIs) that exist today.
Sexually transmitted infections (STIs), also known as sexually transmitted diseases (STDs), are infections that are primarily transmitted through sexual contact, including vaginal, or oral sex. They can be caused by bacteria, viruses, parasites, or other organisms. STIs can affect people of all genders and sexual orientations.
Some of the most common STIs include chlamydia, gonorrhea, syphilis, human papillomavirus (HPV), herpes simplex virus (HSV), human immunodeficiency virus (HIV), and hepatitis B and C. It's important to note that the number of known STIs can change over time as new infections are discovered or classified.

Answer: Stem cell research is very resourceful to our community. Embryonic stem cells are pluripotent cells that can generate most stem cell types, and by studying them we can learn more about the process of development. A use of stem cell research is doctors studying them to increase the understanding of how diseases occur. To obtain as source of stem cells without risking life one can use the method of induced pluripotency, in which pluripotent stem cells can be made from adult stem cells
Explanation:
The range of cells receiving the content of copied cells is called the destination area. The correct option is a.
The smallest unit of life is a cell. It is composed of biomolecules. Every living thing is composed of several cell units. Different sorts of creatures contain various types of cells.
The cell divides to form the other cell. This process if called cell division. Cell division occurs during mitosis. All eukaryotic cells go through the process.
There are four stages to the process. The cell divides during the procedure. A daughter cell that is identical to the parent cell is created.
The destination region refers to the set of cells that will get copied cell content. The cell copies the full contest for another cell.
Thus, the correct option is a. destination area.

Biological classification is the process by which organisms are grouped, sorted, and classified based on their similarities and differences. Organisms are grouped into categories called taxa, which follow a hierarchical system. The major steps involved in biological classification are:
1. Observe and compare organisms: Scientists study various organisms and their characteristics, including physical appearance, behavior, and molecular makeup.
2. Identify shared characteristics: By comparing organisms, scientists identify common traits and features that can be used to group them together.
3. Create taxonomic groups: Based on these shared characteristics, organisms are grouped into hierarchical categories, such as kingdom, phylum, class, order, family, genus, and species.
4. Assign scientific names: Each group and individual organism is given a unique scientific name, usually following the binomial nomenclature system, where the genus and species are used to identify an organism.
5. Continuously revise and update classifications: As new information and discoveries are made, scientists may need to reevaluate and revise the classification system to ensure accuracy and reflect the relationships among organisms.
Overall, biological classification helps scientists to better understand and organize the vast diversity of life on Earth, making it easier to study and conserve species and ecosystems.

species
phyla
genera
A genus is subdivided into smaller groups called species. Therefore, option (B) is correct.
Taxonomy is the study and practice of categorizing or classifying. A taxonomy (or taxonomical classification) is a categorization scheme, especially a hierarchical classification, that organizes things into groups or kinds.
There are seven primary taxonomic ranks: kingdom, phylum, class, order, family, genus, and species. In addition, domain, which was proposed by Carl Woese, is now commonly used as a fundamental rank, although not being listed in any of the nomenclature laws, and is synonymous with dominion.
A genus is a taxonomic rank composed of species grouped based on shared features (having similar structures or dissimilar characteristics) or evolutionary relationship. It is one of the eight major taxonomic ranks used to classify living organisms. It is subordinate to the family and superior to the species.
