Chromosomes are found in the (i) of every living cell. They can be seen by (ii) a cell that is about to (iii). For each thread-like chromosome there is another one exactly like it; therefore chromosomes occur in (iv). Every body cell of a particular organism has the same (v) of chromosomes. For example, all humans have (vi) chromosomes in each body cell, made up of (vii) pairs. The cells of the garden pea have 14 chromosomes made up of (viii) pairs and those of the shrimp have 254 chromosomes, made up of (ix) pairs. The two chromosomes belonging to a matching pair are called (x) chromosomes.

Explanation:

i) nucleus

ii) mitosis

iii) split

iv) pairs

v) number

vi) 46

vii) 23

viii) 7

ix) 127

x) arm

"a.) well–developed vascular system."

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
