The solidarity of all countries will be ESSENTIAL to ensure equitable access to COVID-19 health products.Global research databaseWHO is gathering the latest INTERNATIONAL multilingual SCIENTIFIC findings and knowledge on COVID-19. The global literature cited in the WHO COVID-19 database is updated daily (Monday through Friday) from searches of bibliographic databases, hand searching, and the addition of other expert-referred scientific articles. This database represents a comprehensive multilingual source of current literature on the topic. While it may not be exhaustive, new research is added regularly.Search COVID-19 DatabaseDownload COVID-19 DatabaseThe WHO evidence retrieval sub-group has begun collaboration with key partners to enrich the citations and build a more comprehensive database with inclusion of other content.

Gold number of GELATIN =0.01.This MEANS that 0.01 mg gelatin is required to be ADDED to 10 ML of gold sol to completely prevent coagulation of 1 mL of 10% NACL solution.Therefore, gelatine added to 1000 mL of gold sol to prevent coagulation = 100.01×1000 =1 mg.

ore tetrad cells are the microspores arranged in a group of FOUR. Microspores are formed from microspore mother cell (MMC). MMC is a diploid cell which undergoes meiosis to form four haploid microspores which are arranged in a tetrad. This PROCESS is KNOWN as MICROSPOROGENESIS.

protein source reaches your STOMACH, hydrochloric acid and enzymes called proteases break it down into SMALLER CHAINS of amino acids. Amino acids are JOINED together by peptides, which are broken by proteases. From your stomach, these smaller chains of amino acids move into your small intestine.

Exocrine glands are glands that secrete substances onto an epithelial surface by way of a duct.[1] Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, prostate and MUCOUS. Exocrine glands are ONE of two TYPES of glands in the human BODY, the other being endocrine glands, which secrete their products directly into the bloodstream. The liver and pancreas are both exocrine and endocrine glands; they are exocrine glands because they secrete products—bile and pancreatic juice—into the gastrointestinal tract through a series of ducts, and endocrine because they secrete other substances directly into the bloodstream.Explanation:u hope u LIKE my ans

To test the action of saliva on FLOUR, Amylase test is conducted. Procedure:Add a pinch of flour to a test tube half filled with water, mix it properly.Add a few drops of iodine solution to the mixture.If the solution turns blue, then the presence of starch in the flour is confirmed.Again add a pinch of flour to a test tube filled half with water, mix it properly and DIVIDE the mixture into two parts by transferring it to another test tube. Two ONE of the test tube, add a few drops of saliva and leave it for 30 to 45 minutes.Add iodine solution into both the test tubes.It is observed that the solution with saliva in it does not turn blue, whereas the solution WITHOUT saliva turns blue. The starch present in the flour traps the iodine INSIDE its structure and hence blue colour is observed. Saliva has amylase enzyme in it which dissolves starch to simpler sugars and hence the solution with saliva in it could not show blue colour due to lack of starch.plz marks me as brainliest

Heredity is important to all living ORGANISMS as it determines which TRAITS are passed from parent to child. Successful traits are more FREQUENTLY passed along and over TIME can change a species. Changes in traits can ALLOW organisms to adapt to specific environments for better rates of survival.

re several types of endocrine hypertension, including: PRIMARY hyperaldosteronism: a hormonal DISORDER that leads to HIGH blood pressure when the adrenal glands produce too much aldosterone HORMONE, which RAISES sodium levels in the blood.

Decomposers CLEAN the environment by decomposing WASTE .They INCREASES the CONTENT of humus in soil .

leus is known as the control centre of the CELL and CARRIES the genetic material.If the nucleus is removed from the cell then the cell will not be able to FUNCTION PROPERLY, it will not be able to grow. All the metabolic functioning of the cell will stop. Without nucleus the cell will lose its control.

ernal FERTILISATION is the process of fusion of MALE and female gametes outside the body or in the outer environment. As animal releases gametes in the external environment, there are the minimum chances of fertilisation. This is because of the outside changes that can otherwise DAMAGE the gametes before FERTILIZATION takes place. Thus, a large NUMBER of male gametes are produced to ensure better chances of fertilisation.

Three major events occur in PLANT CELLS during photosynthesis: (1) ABSORPTION of light ENERGY, (2) conversion of light energy into chemical energy, and (3) storage of chemical energy in SUGAR

a SHOPKEEPER BOUGHT 25 chair at the rate of rs.500 per chair.he SOLD 10 of them at the rate of rs.600 per chair and remaining at the rate of rs.300 per chair.find his gain or loss percentExplanation:72 is the answer

The PYRIMIDINES, cytosine and THYMINE are smaller structures with a single RING, while the PURINES, adenine and guanine, are LARGER and have a two-ring structure.

The ANSWER is a OPTION A

1• In a bisexual flower inspite of the young stamens being removed artificially, the flower produces fruit2• Unicellular organisms reproduce by asexual reproduction which is simple DIVISION of parent cell into two daughter cells. ... Hence, cell division can be considered as mode of reproduction in single celled organisms.3• Clone refers to offspring of an organism formed by asexual method of reproduction. Since they possess exact copies of the DNA of their parent, clones exhibit remarkable similarity.4• Each gamete has 23 (n=Haploid) chromosomes that MEAN HALF the number of chromosomes in a parent cell (diploid 2n=46 chromosomes). ... Hence both the parents and offspring have the equal number of chromosomes.5• When the colony of yeast is in water, it does not get nutrition. ... As the yeast gets nutrition and thus energy, it grows and begin to produce buds. This is why colonies of yeast fail to multiply in water, but multiply in sugar solution.6• Bread mold grows profusely on a moist slice of bread RATHER than on a dry slice of bread because microorganisms need optimum temperature and moisture to grow and if there is no moisture they will not grow profusely.7• Production of genetic VARIATION during sexual reproduction is result of: (1) Meiosis during gamete formation; crossing over and independent assortment of genes produce genetic variations.8• Planaria possesses great power of regeneration. Thus if the body is cut into two vertical halves, each piece of the body of Planaria grows into a complete individual.Explanation:please mark as BRAINLIEST (◍•ᴗ•◍)❤

Living fossil- an ORGANISM (such as a horseshoe crab or a ginkgo TREE) that has remained essentially unchanged from earlier geologic times and whose close relatives are usually extinct.Other examples of living FOSSILS are SINGLE living species that have no close living relatives, but are survivors of LARGE and widespread groups in the fossil record. For example: Ginkgo biloba. Syntexis libocedrii, the cedar wood wasp.
