D. “The scientific name Asteroidea was given to starfish by the French zoologist de Blainville in 1830. It is derived from the Greek aster, ἀστήρ (a star) and the Greek eidos, εἶδος (form, likeness, appearance). The class Asteroidea belongs to the phylum Echinodermata.”

E. “First, primates have larger eyes than many other mammals of comparable body size (Ross & Kirk, 2007). Having large eyes ensures that a large image is formed on the retina (Walls, 1942; Land & Nilsson, 2002). This large retinal image may then be sampled by many photoreceptors, improving visual resolution. Primates have flexible shoulder joints and and strong clavicles or collar bones that help them use their arms more effectively than other species of animals. Most primate can hold their bodies erect and some species, including humans, can walk on two legs instead of four.”

The calcium present in the milk acts as a fertilizer, for the growth of pumpkin size.

Explanation:

Scientific answer: Milk contains nutrients, minerals mainly calcium which are good for the growth of the plant as a fertilizer.

Milk gets readily absorbed by the roots due to the solubility of nutrients in milk.

The root hairs of the plant transport the calcium to the other parts like stem.

This will only help when all other factors of plant growth are present as sunlight, water other than fertilizer.
