Answer:
The skin provides a protective layer for the inner organs, helps to regulate temperature, water balance, receives sensory stimuli, produces vitamins, etc.
Explanation:
The integumentary system can be defined as an organ system composed of different organs, i.e., skin, hair, exocrine glands, nails. The skin helps in homeostasis by providing a protective layer for the inner organs, contains immune cells involved in immune responses, regulates temperature, water balance, receives sensory stimuli, production of vitamins. The skin contains sensory receptors for different stimuli including touch, pain, pressure, and temperature (both heat and cold receptors). The inflammatory response (inflammation) occurs when harmful microorganisms penetrate the skin, thereby causing skin inflammation. The skin's immune cells include, among others, neutrophils (located in the reticular dermis), macrophages (papillary and reticular dermis), T lymphocytes (epidermis and papillary dermis), Langerhans cells (epidermis), etc.
Answer:
(A) The amount of rainfall
Explanation:
Abiotic means not living, biotic means living. Rainfall is not a livig organism, while the other options are.
Cocoa is the dried and fully fermented fatty seed of the cacao tree from which chocolate is made. "Cocoa" can often also refer to the drink commonly known as hot chocolate; cocoa powder, the dry powder made by grinding cocoa seeds and removing the cocoa butter from the dark, bitter cocoa solids; or it may refer to the combination of both cocoa powder and cocoa butter together

Climate
Cocoa can be grown up to 300 m above mean sea level. It requires a minimum of 90-100 mm rainfall per month with an annual rainfall of 1500-2000 mm. The plants need equitable climate with well distributed rainfall. If dry periods are prolonged, irrigation scheduling is necessary. The temperature range of 15°-39°C with optimum of 25°C is considered ideal.
Soil
Cocoa requires deep and well drained soils. Poorly drained soil affects growth of plants. Majority of area under Cocoa cultivation is on clay loam and sandy loam soil. It grows well in the pH range of 6.5 to 7.0.
Shade requirement
Cocoa was evolved as an under-storey crop in the Amazonian forests. Thus commercial cultivation of cocoa can be taken up in plantations where 50 per cent of light is ideally available. In India, coconut and arecanut gardens are suited best for cultivating Cocoa. Under arecanut 30-50% of sunlight penetrates through their canopy which can be intercepted by cocoa.

Explanation:
The right answer is True.
A watershed is the expanse of territory drained by the waters of rivers and lakes, which in turn converge to a common outlet. Groundwater is flowing into the watershed, although the boundaries may not exactly coincide with surface water. Smaller flow areas that feed subwatersheds can be called catchment basins or drains. Watersheds can flow into river basins that may encompass larger areas.
Known watersheds are separated from one another by ridge lines, also known as watersheds. These are designed to delineate the watershed.
Watersheds are nested networks, the smaller ones nesting in larger ones. Streams that form the watershed can be organized according to a ranking framework. For example, the upper streams at the highest elevation of the watershed are first class streams.
When two first-class rivers meet, they form a second-rate stream. When two second-rate rivers meet, they form a third-class watercourse. A stream joined by another lower ranking stream retains its rank. For example, a third-class watercourse joined by a first or second-rate watercourse remains a third-rate watercourse.
