Answer:To test whether iodine or starch have crossed the synthetic membrane, you will look for a change in color. A solution of iodine is tan and a solution of starch is clear or milky white; when iodine and starch are together in the same solution, the solution is purple, dark blue or black.

Explanation:
A) Peptide hormones are not lipid soluble hence known as lipophobic and cannot diffuse through cell membranes examples of peptide hormones include luteinizing hormones, thyroid stimulating hormones, insulin and follicle-stimulating hormones.
B) Steroid hormones can not stored in secretory vesicles because of their lipophilic nature.
C) Amino acid-derived hormone are the hormones which are derived from tyrosine and tryptophan.
D) Anterior pituitary lobe of Pituitary gland is true endocrine gland of epithelial origin.
E) Hypothalamus produce screates six hormones in which vasopressin is also synthesized.
F) Posterior pituitary is responsible for storage and release site for oxytocin
Plant has such a developed structure to protect they have cell wall which give it rigidity and structure and also have cellulose which provide strength
The three examples of cycles of inorganic nutrients are Nitrogen, carbon and sulphur cycle.
Nitrogen is required to make amino acids and DNA in organisms. Carbon is the main component of glucose through which organism make energy, about 18 per-cent of the human body comprises carbon. Sulphur is an important constituent of some proteins, amino acids and enzyme cofactors.
Explanation:
The biogeochemical cycles like the nitrogen cycle are responsible for converting nitrogen into many chemical forms as nitrates, nitrites, ammonia. This process involves degrade decomposing animal and plant matter and naturally cleaning the environment also nitrites and nitrates become biofertilizers. The plants take nitrogen through their roots and in turn primary consumer in food chain ie. organisms consume the plant and eventually releases nitrogen as a waste material, dead and decaying body to the soil and cycle goes on.
In the carbon cycle the carbon is exchanged from the atmosphere to the organisms and then again to the environment. Plants perform photosynthesis by using carbon dioxide, primary consumer eats it and gets nutrition to perform cellular respiration, in turn, gets energy which gets dissipated and stored as biomass eventually in the course consumer die and replenish the soil with carbon. The Carbon emitted will keep cycling through air, water and soil.
The sulphur cycle involves the movement of sulphur between rocks, water and living beings and plants. Plants ( producers) absorb sulphur dissolved in water and animal consume these plants to replenish their sulphur requirement. And when organism die, sulphur enter the cycle again.
There will be a transfer of these inorganic nutrients to the trophic level in food chain.
