1.b, 2.b, 3.c, 4.b and 5.b

Step-by-step explanation:

5) 120 is positive number so it is true.

However 1.2 is also a positive number so (a) is also true.

1.b, 2.b, 3.c, 4.b and 5.b

Step-by-step explanation:

5) 120 is positive number so it is true.

However 1.2 is also a positive number so (a) is also true.

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

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.
