What does absense of MHC Class I indicateAlmost all nucleated cel.pdf

Ankitagarwaleleraipu

What does absense of MHC Class I indicate? Almost all nucleated cells will have MHC Class I molecules on their surface and their main role is to present foreign protein to cytotoxic T cells (Tc Cells) so that the cells which got infected can be cleared by these Tc cells. But in some cases, it has been observed that some tumor cells will escape killing or elimination by Tc cells by becoming MHC Class I negative, here they will not express MHC Class I molecules on their surface and thus there will not be any expression of tumor antigens to Tc cells and these will survive and will go on producing new cells and form the tumor. Like this MHC class I negative cells present within the primary tumor will develop into unnoticed micrometastases and will have an immunological equilibrium and succeeds in surviving in a dormant stage for long periods of time What does the presentation of tyrosinase indicate? The tyrosinase will cleave the tumor proteins and will express the melanoma antigens on the cell surface as peptides and overexpression of these antigens in tumor cells will result in an abnormally high density of specific peptide:MHC complexes on the cell surface making them immunogenic and provides them tolerance and is seen as tumor rejection in most of the cases. What dos decreased CTL infiltratioin indicate? It is the CD8+ cytotoxic T lymphocytes (CTLs) which will reject the tumor by infiltrating the solid tumors by recognizing the tumor antigens, and will kill those tumor cells. And to do this CTLs will try to infiltrate tumors in depth and it is done only when tumor cells express the cognate CTL antigen. If the tumor will not express the cognate antigen, CTL infiltration will not occur and the tumor cells cannot be killed and so the expression of tumor antigen on the cells will attract CTL infiltration, at the same time when the tumor antigens are not presented on these cells, it will decrease the CTL infiltration.

The document discusses two genetic maps between genes c and d. Map 1 shows a distance of 15 between the genes, while Map 2 shows a distance of 20. Since a greater distance between genes means more recombinants, the F1 offspring from parents 4 and 5 have a greater chance of losing homozygous recessive alleles due to less linkage between genes c and d in Map 2. Therefore, the F1 from parents 4 and 5 is most likely.

Phototaxisthe Phenomenon of movement of motile unicellular organis.pdf

Ankitagarwaleleraipu

Phototaxis the Phenomenon of movement of motile unicellular organisms such as algae and bacteria toward or away from light is termed as phototaxis movement. This is advantageous for phototrophic organisms as they can orient themselves most efficiently to receive light for photosynthesis. Phototaxis is called positive if the movement is in the direction of light and negative if the direction is opposite. Phototropism, Growth with respect to light, expressed in all shoots and some roots. Phototropism is one of the many plant tropisms or movements which respond to external stimuli Charles Darwin studied plant growth phenomena involving tropisms. He found the bending of plants toward light. This phenomenon, which is caused by differential growth, is called phototropism. In experiments he used seedlings of canary grass (Phalaris canariensis), the youngest leaves are sheathed in a protective organ called the coleoptile. Coleoptiles are very sensitive to light, especially to blue light . If illuminated on one side with a short pulse of dim blue light, they will bend (grow) toward the source of the light pulse within an hour. Simillarity between Phototaxis and phototropism Both are related with abiotic factor i.e light. ___________________. .

Marijuana is also called as cannabis and it is a preparation of cannabis plant and it is used as a psychoactive drug or medicine. Characteristics of Cannabis were studied to determine the suitable and efficient environmental conditions for its indoor mass cultivation for pharmaceutical studies. Effect of different photosynthetic photon flux densities,temperature and CO2 concentrations on gas and water vapour exchange characteristics of the Cannabis. The rate of photosynthesis and water use efficiency of Cannabis increases with photosynthetic photon flux densities at lower temperatures. Genrally the photosynthetic process will occur by taking the carbondioxide and water and in the presence of sunlight and chlorophyll it forms the glucose and oxygen and from the glucose the plant makes the cellulose which gives the fibrous structures to the plant. The osmosis process helps in the absorbption of water and minerals from soil. The osmotic pressure mainly helpful in intake and transport of minerals and the soil condition also plays an important role. Cannabis gives its potential for better survival,growth and productivity in drier and CO2 rich environment.

AnswerThe following molecules would not require carrier transport.pdf

Ankitagarwaleleraipu

Answer: The following molecules would not require carrier transporters: a) carbon dioxide c) progesterone The following molecules would require carrier transporters: b) fructose d) arganine e) adenosine diphosphate Polar molecules and large ions dissolved in water cannot diffuse freely across the plasma membrane due to the hydrophobic nature of the fatty acid tails of the phospholipids that make up the lipid bilayer. Only small, non-polar molecules, such as oxygen and carbon dioxide, can diffuse easily across the membrane. Hence, no nonpolar molecules are transported by proteins in the form of transmembrane channels. These channels are gated, meaning that they open and close, and thus deregulate the flow of ions or small polar molecules across membranes, sometimes against the osmotic gradient. Larger molecules are transported by transmembrane carrier proteins, such as permeases, that change their conformation as the molecules are carried across (e.g. glucose or amino acids). Non-polar molecules, such as retinol or lipids, are poorly soluble in water. They are transported through aqueous compartments of cells or through extracellular space by water-soluble carriers (e.g. retinol binding protein). ADP/ATP translocases, also known as adenine nucleotide translocases (ANT) and ADP/ATP carrier proteins (AAC), are transporter proteins that enable the exchange of cytosolic adenosine diphosphate(ADP) and mitochondrial adenosine triphosphate (ATP) across the inner mitochondrial membrane.

AnswerCyanide is an irreversible enzyme inhibitor of Cytochrome C.pdf

Ankitagarwaleleraipu

Answer: Cyanide is an irreversible enzyme inhibitor of Cytochrome C Oxidase (Complex IV) the fourth complex in the electron transport chain. Cyanide ions bind to the iron atom of the Complex IV in the mitochondrial membrane, which results in blockade of electrons transfer to the final electron acceptor oxygen. This blockade causes build up of proton motive force in the intermembrane space as the protons are not allowed to flow back into the matrix which subsequently halts ATP production.

Ankitagarwaleleraipu

A respiratory therapy professional diagnoses and treats those suffering from chronic and other respiratory problems. Some of their patients with respiratory problems would be: • Premature infants • Asthma patients • Patients with lung infections • Heart patients A respiratory therapist (RT) has a variety of job responsibilities. These include talking to patients, gathering information regarding their medical condition, diagnosing breathing conditions and associated treatments, informing the family about the respiratory therapy treatments, etc. Respiratory therapist must update their professional respiratory knowledge periodically and need to be well versed with the latest available techniques, treatments and diseases in respiratory therapy. Care Respiratory therapists often work in medical facilities such as hospitals and nursing homes. They administer oxygen, perform CPR, use ventilators, and give medicines as needed. The ability to provide this care and build relationships with patients is an advantage for people who want to work in the medical field without becoming a medical doctor. Therapists who work in extended care facilities like nursing homes have an even longer time to develop relationships with their patients. Misconception among nurses about a respiration therapist: STRESS: Nurses do think that, being a respiration therapist could be strenuous and stressful, as they spend the majority of the day on their feet. The care that respiratory therapists provide deals with one of the most basic and important life activities -- breathing. Helping people through breathing struggles is stressful under normal conditions. For those therapists who work in hospitals, the stress is more constant. Administering CPR and assisting with treatment in emergency rooms is high pressure. Another factor that can add to the stress is working with children who have breathing issues, or who have been in a drowning accident or other type of accident that has compromised their respiration. WORK CONDITION and ENVIRONMENT: Nurses do believe that, RTs may have to work on weekends, holidays, and various shifts and may also have to work extended hours in case of emergency. A career in respiratory therapy also means being exposed to infections and micro-organisms. Another misconception is that, as being a registered nurse, they do have more opportunities of different places to work like hospitals, clinics, doctor\'s offices, jail\'s, factories, home health, and of course as a school nurse. whereas, as RTs, well not so many as they could work on just hospitals and home health. These are the major misconceptions among nurses about a respiratory therapist.

Some of their patients with respiratory problems would be: • Premature infants • Asthma patients • Patients with lung infections • Heart patients A respiratory therapist (RT) has a variety of .

Ankitagarwaleleraipu

wo (-2) above the O3 means there are 2 extra electrons available for bonding. Polyatomic ions are groups of atoms joined together by covalent bonds, like molecules, except that they have a charge. The only difference between the process for drawing Lewis diagrams for molecules and for ions is in determining the number of available electrons. Count the valence as before then add an electron for each unit of negative charge or subtract one for each unit of positive charge. For example, the sulfite ion has the formula SO32-. The number of valence electrons is 6 + 3*6 + 2 = 26. The atom with the highest electronegativity in the sulfite ion is the sulfur, so it belongs in the center of the diagram with oxygen atoms bonded to it. Fill in enough bonds to hold the ion together then add non-bonding electrons until all atoms obey the octet rule or you have used all that are available.
