Answer:The perimeter of the field = 90 mStep-by-step EXPLANATION:Given that:Breadth of the rectangle = 9 mLength is FOUR times of Breadth i.e., 4 × 9 = 36 mTo find:Perimeter of the field. Formula to find the perimeter of a rectangle:Perimeter of a rectangle = 2(L + B) unit. Here, Length is denoted by L. Breadth is denoted by B. Finding the perimeter of field which is in rectangular in shape:➼ Perimeter of field = 2(36 + 9) m➼ Perimeter of field = 2 × 45 m➼ Perimeter of field = 90 m

re two ways bacteria can harm the human body: toxicity – the bacteria produce toxins which damage specific tissues in the body. invasiveness – the bacteria multiply rapidly at the site of infection and overwhelm the body's defence MECHANISMS. The bacteria may then spread to other parts of the body. Differences Between Monocots and DicotsMonocots can be defined as the plants with the seed having only ONE cotyledon, and the plant is CALLED as monocotyledons, while plants with the seed having two cotyledons are called as dicots, and the plant is called as dicotyledons.In monocots the embryo has only one cotyledon, the pollen tube contain single pore or furrow (monocolpate), whereas in dicots the embryo has two cotyledons and the pollen tube have three or more pore or furrow (tricolpate).The FLOWER parts are present in multiples of three in the monocotyledons, even the secondary growth and cambium is absent, but in dicots, the flower parts are present in multiples of four or FIVE, even secondary growth and cambium is present

The question of where we humans COME from is one many people ask, and the answer is getting more complicated as new evidence is emerging all the time.For most of recorded history humankind has been placed on a metaphorical, and sometimes LITERAL, pedestal. Sure, modern humans were flesh and blood like other animals.But they were regarded as being so special that in the Linnaean taxonomy that prevailed well into the second HALF of the 20th century they were GIVEN their own family, the Hominidae.This distinguished them from the Pongidae, the separate family used for the three African great apes – the common chimpanzee, bonobo and gorilla – plus the orangutan from Southeast Asia.We now realise that modern humans are just one of the African great apes.So when and how did this RADICALLY changed perception come about?

Examples include mustard, brinjal, China rose, lupin, SUNN hemp, gram, bean, chili, petunia, tomato, withania, potato, onion, aloe, and tulip. In perigynous flowers, the gynoecium is in the center and ovary is HALF inferior. Examples include plum, rose. In epigynous flowers, the ovary is inferior and it is enclosed by thalamus and gets fused with other parts. Examples include guava, cucumber, bitter GOURD, pumpkin.Thus, the correct answer is 'Fifteen.'
