Surface proteins What is the function of surface marker proteins like the major histocompatibility complex? 1 Surface marker proteins are enzymes that break down food molecules that are then absorbed. 2 Surface marker proteins are receptors for hormones that then send messages out of the cell. 3 Surface marker proteins are ion channels that allow ions to enter the cell. 4 Surface marker proteins are identifiers that allow the immune system to recognize “self” cells. 5 Surface marker proteins are anchoring proteins that attach neighboring cells to each other. Solution 4. Surface marker proteins are identifiers that allow the immune system to recognize . Surface marker are the marker which are present on the surface of the cell they act like a receptor where the binding of antigen antibody happen which will cause a immune response. The immune system uses these proteins to tell friendly cells from foreign invaders. They are as unique as fingerprints. They play an important role in organ transplants..

list in order of appearance the four stages of the origin of life and explain what was necessary to occur in order for life to have evolved in this fashion Solution Evolution occurred in four stages: Stage 1: Initially, it is thought that various small inorganic molecules occurred in the primitive Earth. Hydrogen, ammonia, methane and water vapor were the main components. These molecules combined together to form small organic molecules, which included amino acids. Please note that ultraviolet radiations of the sun aided this process. This phenomenon is known as Abiogenesis. Abiogenesis was important for the beginning of evolution in successive stages. If abiogenesis did not occur, complex molecules (which form from small organic molecules) will never form. Stage 2: In this stage, the simple organic molecules (amino acids) further accumulated to form complex and large organic molecules like proteins (polymers). Water, oxygen, ozone and enzymes evolved into the primitive Earth. This stage was important because, it resulted in the formation of enzymes, the biological catalysts, without which life of present Earth is impossible. Stage 3: Polymers interacted together to form aggregates. These were known as proto-bionts. They had the capability of reproduction. So, abiogenic evolution shifted to biogenic evolution. Now new organisms/life will generate from pre-existing life. This stage was important because of the introduction of concept of evolution. Stage 4: Protobionts generated the ability of reproduction. So, genetic material could be transferred from one generation of other. This stage was important for variation and evolution. RNA was originated, and its work into the living systems was well-established in this stage..

i. What does Diaspora means? 2 Diaspora peoples refer to who? Name the two places diaspora peoples main their connection and identity State one reason Diaspora study has become much more important today s State one characteristic of diaspora groups: What does African Diaspora means? In studying African Diaspora History, one has to begin with what and why? State one reason why it is complex and difficulty to study African Diaspora history Name two Muslim societies outside Africa that have discrete African communities. e Name one service performed by enslaved Africans who settled in India. 11. What were the known names for Africans and descendants of Africans found in India? What region of Africa did Arab slave dealers take most of the African slaves? 13. Name a Greek Mathematician who is believed to have studied in Egypt. . What is the Hamitic Hypothesis? s Define Monogenesis and Polygenesis. Describe the \"Out of Africa\" Theory 17. Name the two scientists whose works have closely associated with the \"Out of Africa\" Theory Based on the video about the dawn of man, what year was the first human-like skeletons Solution Q.1 In general meaning, Diaspora refers to the people living or dispersed at places outside of the homeland or homenation. So if I say indian Diaspora, it refers to the people of Indian nationality that have permanently moved from India to other parts of the world. If I say African Diaspora, it refers the people from the Africa who have moved to other countries such as America due to some historic movements, such as slavery. Q.2 These are the people who were moved from their homeland for some reason and now are dispersed or scattered in foreign lands, living there permanently. An African-American is a person of African Diaspora, a Mexican-American is a person of Mexican diaspora and an Indian- American is the person of Indian diaspora. Q.3 For African people in America brought by slavery, maintaining their identity was not a difficult task, because they were easily distinguished by the black skin color, but among other diasporas such as Jews other factors contribute to the fact that they maintained their identity for more than 3000 years. Jews people maintained a reading culture, and they are taught about the purpose of their life. So the main factor that has contributed in the religion. And on the day of the Sabath, they don\'t just pray, but they meet at one place in groups and together they pray. So these religious gathering places also contribute. Similarly for any other other religion, the places of religious worship contribute in maintaing the identity of the people and creating connections..

How do these primary source images reflect how human societies operated in the prehistoric world? Prehistoric Cave Paintings, various locations worldwide, 10,000 to 35,000 BCE Woman of Willendorf, stone, 25-28,000 BCE, 4.4 inches Solution It is difficult to reconstruct the human society as it existed 35000 years ago from the painting that they had painted over the surface of the caves. It seems that humans primarily hunted for their food. The study of the paintings seems to suggest that the majority of the paintings were done by young men though some of the hand prints in some of the caves seem to be those of women. Women may also have painted. Writing was not a part of human culture when the paintings were made and the meaning of the paintings remain elusive. Perhaps some rituals and traditions and faith in an omnipotent creature were the reasons for the paintings. The use of the caves is also not clear. The caves are found in remote regions and while the paintings are found in the interior of the caves also, it is suggested that the occupation of the caves was only in the mouth of the caves. The paintings may have been used to impart survival lessons, hunting strategies or to portray legends or to illustrate traditions and rituals. The woman of Willendorf Nothing is known about the portrayal of the female figure in the Woman of Willendorf. It is quite clear that the features of the figure are exaggerated. The figure has no feet so perhaps it was fixed to the ground and worshipped as a goddess. The features of the head and face are not visible . It is also thought that the statue may be a representation of the fantasy of the young man (men) who made the statue..

How does vesicle budding occurs in yeast?Does the vacuoles uses CopI or CopII formation or is there a specific budding mechanism in yeast? Please explain in details. Solution Sec proteins are responsible for vesicle budding. These proteins are present in vesicle named as Cop II. This is a coat protein that makes up the vesicle. Please note that Cop II vesicles bud off proteins from ER towards cis-Golgi, while Cop I vesicles bud off proteins from cis-Golgi to trans-Golgi. The mechanism of budding is similar in yeast; in fact yeast has been used as a model organism for studying vesicular transport and secretory pathway of eukaryotes. Vacuoles also Cop I and Cop II formation..

1. Explain the significance of each of the following types of VLAN: Data, Management, Native, and Blackhole. Explain where each type of VLAN fits into a LAN network. In addition, what is the default VLAN on a Cisco switch for Data, Management, and Native frames? Justify your answer Solution There are different types of VLANs. The type of network traffic they carry defines a particular type of VLAN and others derive their names due to the type or a specific function the VLAN performs. The following describes common VLAN: A data VLAN also known as a user VLAN is configured to carry only user-generatedtraffic. The importance of separating user data from other type of VLAN is proper switchmanagement and control. A Management VLAN is any VLAN you configure to access the managementcapabilities of a switch. A Native VLAN is assigned to an 802.1Q trunk port. An 802.1Q trunk port supportstraffic coming from many VLANs as well as traffic that do not come from a VLAN. The802.1Q trunk port places untagged traffic (traffic that does not come from a VLAN) onthe native VLAN. A Blackhole VLAN is a term used for a vlan configured for unused ports. It’s a securitypractice, whereby you create a vlan that has no route, or no default gateway to othernetworks within your organization, or to the internet. The Default VLAN is simply the VLAN which all Access Ports are assigned to until they are explicitly placed in another VLAN. In the case of Cisco switches (and most other Vendors), the Default VLAN is usually VLAN 1. Typically, this VLAN is only relevant on an Access port, which is a port that sends and expects to receive traffic without a VLAN tag..

Culture & Religion- Any country\'s culture & religion greatly affect how consumers xconsume in that country. THerefore MNEs have to factor that before entering that market. As these issues are closer to every human, MNEs should tread carefully. 2. Ethics-Ethics also vary from country to country Some things that are ethical in one country may be unethical in another country. Also, MNEs are viewed with suspicion by NGOs & others as they think that are more likely to do unethical thing. 3. Corporate Social Responsibility-In some cointries this has become essential. While in many countries, there is no mention of it However, MNEs should invest in it as it generate goodwill, good media for the firm. 4. Relationship & Trust-MNEs need to have good relationship with adminstration & general public to create a viable environment for itself to work in that country..

DNA is replicated before this process In animals, results in the production of sperm nuclei and egg nuclei Tetrads align at the middle of the cell Pairing of homologous chromosomes is necessary Ends up with four nuclei from one original nucleus Is necessary for a human fetus to develop Chromosomes align in a single file line in the middle of the cell at some point in the process. Solution 41) Both 42) Meiosis 43) Meiosis 44) Meiosis 45) Meiosis 46) Mitosis 47) Both During mitosis, the chromosomes of parent cells will be duplicated to get equally distributed among two daughter cells. Whereas meiosis is a reduction division, where one diploid cell will divide to generate haploid cells. DNA replication takes place during mitosis as well as during meiosis interphase I. Meiosis produces four cells with only one set of chromosomes (n), so it is involved in the production of sperms and eggs and these during fertilization fuse to produce a fertilized egg (2n). Tetrads are formed with the pairing up of homologous chromosomes during the process of Crossing-over, and it occurs only during meiosis. It is the mitosis, or normal cell division which helps the human fetus to develop through deposition of extracellular materials as the embryo grows..

describe the parallel and difference between allopatric speciation and sympatric speciation. Solution Allopatric speciation and sympatric speciation are both types of speciation in which ancestors were common and lived in same geographical area. Differences: Allopatric speciation takes place when two populations of a species are separated by some geographical barriers such as a river or a valley. Due to the geographical isolation, the two populations can not mate and develop into different species over time.\' Sympatric speciation takes place between two populations in a same geographical region. The two populations do not mate due to ethological (male and female do not attract each other) or mechanical or temporal differences. Over time these populations develop into different species..

Define passive and active in terms of energy requirement. Describe the following types of transport and identify if each type requires energy and in what form. Simple diffusion Facilitated diffusion Osmosis Primary active transport Secondary active transport Solution Active transportneeds energy, and it help to move ions against their concentration gradients. The concentration of some of the ions is more inside the cell and some is more outside the cell. For example, the concentration of sodium ions is more outside the cell. Still, the sodium ions move from the inside of cell to outside through ion channels, by means of active transport. Passive transport of molecules is independent of energy requirement, and the transport or diffusion of molecule across the channel is facilitated by the concentration gradient. Means, the molecules move down their concentration gradients. 1). Simple diffusion: Simple diffusion is a process of passive transport in which molecules diffuse down their concentration gradient. Diffusion of molecules mainly depends on the lipid solubility and their size and polarity. It does not require the carrier molecules as in case of facilitated diffusion. Small molecules such as water, gases such as oxygen, carbon dioxide, ions such as hydrogen ions, etc. can pass through the cell membranes and membranes of cellular organelles by means of simple diffusion. 2). Facilitated diffusion involves the transport of transport of molecules using the membrane bound proteins. For example, ion channels allow the transport of ions into and out of the cell, which are otherwise, cannot pass through cell membrane. Glucose binds to the carrier molecule present on the cell membrane, and enter into the cell; this process is facilitated by insulin. 3). In the primary active transport, the ATP is directly used for the transport of the molecule. For example, The Na+/K+ ATPase pump transports sodium and potassium ions against their concentration gradients. For every three sodium ions pumped out of the cell, two potassium ions enter into the cell. Thus, the membrane potential is maintained. 4). The secondary active transport is an active transport in which the downhill movement of an ion (either sodium or hydrogen) is coupled with the uphill movement of another molecule (against its concentration) by the transporter protein. Thus, the electrochemical gradient of an ion drives uphill transport of another molecule. Eg: Glucose absorption along with the sodium is an example of secondary active transport..
