The invading microbe or pathogen is called an antigen. It is regarded as a threat by the immune system and is capable of evoking an immune response. Antigens are proteins that are found on the surface of the pathogen.
Which cells allow antigen entry?T and B cells differ in one basic way: whereas T cells bind antigens that have been outlined and embedded in MHC molecules by APCs, B cells function as APCs that bind entire antigens that have not been processed.

(30 points) Mosquitoes can carry and transmit many diseases to humans. In the past, the insecticide DDT was heavily used to reduce mosquito populations in order to reduce instances of disease transmission. However, after some time, mosquito populations developed a resistance to DDT, which made the DDT less effective in reducing mosquito populations.
Based on what you’ve learned about natural selection, in 3–5 sentences, describe how mosquitoes may have come to develop this resistance.
Mosquitoes resistant to DDT are also immune to mosquito net insecticide. A single genetic mutation causes resistance to DDT and pyrethroids according to new research in the diary Genome Biology.
What is DDT and why was it banned?Dichlorodiphenyltrichloroethane (DDT) is an insecticide used in agri company . The United States prohibited the use of DDT in 1972. Some nations outside the United States still use DDT to manage of mosquitoes that laid malaria.

Mosquitoes may have developed resistance to DDT through the process of natural selection. Initially, within a mosquito population, there may have been genetic variation in their response to DDT exposure.
Some mosquitoes may have possessed genetic traits that made them more tolerant to the effects of DDT, while others may have been more susceptible. When DDT was heavily used, the susceptible mosquitoes were killed, while the tolerant ones survived and reproduced. Over time, this led to an increase in the proportion of mosquitoes with the genetic traits for DDT resistance, as they were the ones passing on their genetic information to the next generation. This process of natural selection favored the survival and reproduction of mosquitoes with DDT resistance, resulting in the development of a resistant population.

The science of naming and grouping organisms is called (genealogy / numismatics / systematics / speciation), and the term (families / taxa / kingdoms / species) describes any of the groups of organisms.
Answer:
The science of naming and grouping organisms is called systematics and the term taxa describes any of the groups of organisms.
Explanation:
Genealogy is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members.
Numismatics is the study of the physical embodiment of various payment media (i.e. currencies). The study of numismatics as it applies to coins is often in the research of the production and use of the coins to determine their rarity.
Systematics, or Taxonomy, is the study of the kinds of organisms of the past and living today, and of the relationships among these organisms. Systematists collect and study the variety of plants and animals and group them according to patterns of variation.
Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms.
taxon - taxa: a taxonomic group of any rank, such as a species, family, or class.

From this description, the normal Ras gene is normal Ras gene is a proto-oncogene.
Proto-oncogenes are normal genes involved in regulating cell growth and division. They play essential roles in cellular processes, including signal transduction pathways that control cell proliferation, differentiation, and survival.
However, when certain mutations or alterations occur in proto-oncogenes, they can become oncogenes, promoting uncontrolled cell growth and contributing to the development of cancer.
In the case of Ras, it is a proto-oncogene that codes for the Ras protein.
Thus, the Ras protein is a GTP-binding protein that acts as a molecular switch in intracellular signaling pathways, relaying signals from cell surface receptors to the nucleus.

The carbon, nitrogen, and oxygen cycles, similar as they are all biogeochemical cycles, involve an interaction between living and nonliving elements, and all are part of the earth's system. The correct option is d, all the above.
A chemical substance travels through Earth's biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments via a biogeochemical cycle, also known as substance turnover or cycling.
One of many natural cycles, a biogeochemical cycle involves the movement of conserved matter through the biotic and abiotic components of an ecosystem.

What do you mean by Extinction?Extinction may be defined as an evolutive process that leads to the disappearance of a species or a population from a specific habitat.
The adaptation of mammals probably allowed them to survive even though dinosaurs became extinct because of their diet and lifestyle. Herbivores dinosaurs depend on the plants which are destroyed due to meteorite impacts.
Other mammals changed their diet pattern as well as the place to live they lived in burrows to protect themselves from the firestorm, Dinosaurs being tall do not protect themselves from such activities.
