The circle below is centered at the point (3, 1) and has a radius of length 2.
what is its equation?

b

step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (3, 1) and r = 2, hence

(x - 3)² + (y - 1)² = 2², that is

(x - 3)² + (y - 1)² = 4 → b

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
