Correct Answer: C) Eosin

Explanation

Living things require transportation of substances within their body to perform various functions. The media of transportation in living things include cytoplasm, water, blood, and lymph. However, eosin is not a media of transportation in living things. Cytoplasm is a jelly-like substance that fills the cells and transports organelles. Water is a solvent that dissolves and transports substances within the body, and it is also the medium for various biochemical reactions. Blood and lymph are fluids that circulate within the body and transport nutrients, oxygen, waste products, and hormones. Eosin, on the other hand, is a red dye used in staining biological tissues for microscopic examination. It is not involved in the transportation of substances within living things. Therefore, Option C (Eosin) is the correct answer to this question.

Explanation

(a) Functions of the mammalian skeleton include:

(I) Supports it posture and provides to the body e.g. backbones/ vertebrae/pelvic girdle

(ii) It gives protection — e.g. ribcage protects heart/lungs/cranium(skull) protects brain/vertebrae protects spinal cord/pelvic girdle protects female reproductive organs.

(iii) The skeleton helps in the production of blood cells — in the bone/marrow of the long bones

(iv) Storage of calcium is also encourage, e.g., in the bone matrix

(v) Movement/locomotion is enhanced. — any of the limb bones

(vi) Breathing movements — Riles

(vii) Attachment of muscles is facilitated — any bone

(viii) Provision of shape-axial skeleton/grindles etc

(b) Bones and muscles bring about movement at the elbow in the following ways:

(i) Bicep and tricep act antagonistically to bring about movement at the elbow. The bicep is attached to the scapula and radius; while the tricep are attached to the scapula and ulna

(ii) Bicep contracts while tricep relaxes to cause bending/flexing of the forearm

(iii) Tricep contracts while bicep relaxes to cause straightening of the forearm.

(c) Support in herbaceous and woody Plants can come in different ways:

(i) Herbaceous Plant:

(1) By turgidity, water is preserved

(2) Due to the presence of water, vacuoles inside parenchyma cells/living cells

(3) Thickening of walls of collenchyma cell (at the corners).

(ii) Woody Plant:

(1) Sclerenchyma in the cortex

(2) By the Xylem strengthened by deposits of lignin in their walls

(2) Secondary growth/thickening provides extensive wood / secondary xylem and bark.

(d) The vitamin and mineral element necessary for healthy bone development are:

(1) Vitamin — D/Calciferol, Vitamin C (forms the cement of bow)

(2) Mineral elements — calcium/phosphorus/magnesium.
