Transpiration is the process where plants release water vapour into the atmosphere from their aerial parts, like leaves and stems, through tiny pores called stomata. Transpiration is essentially the evaporation of water from a plant's surface, similar to how humans sweat. When a plant absorbs more water than it can transpire (evaporate through stomata), the excess water, along with dissolved minerals and sugars, is pushed out through hydathodes. The process through which it does this is called guttation.

Chemotaxis is the directed movement of cells or organisms towards or away from a chemical stimulus, playing a crucial role in processes like immune response, development, and bacterial behavior. Thermotaxis is the directional movement of an organism in response to a temperature gradient. Positive thermotaxis refers to the movement of an organism towards a warmer temperature or heat source. Conversely, negative thermotaxis is the movement away from warmer areas or heat sources. Thermotaxis can be crucial for survival and reproduction in various organisms, helping them find optimal temperature conditions or respond to environmental cues. phototaxis refers to the directional movement of an organism, or part of an organism, in response to light, either toward (positive phototaxis) or away from (negative phototaxis) a light source.

Oligochaetes, like earthworms, possess a hydrostatic skeleton where the fluid-filled coelom provides support and facilitates movement through muscle contractions. A hydrostatic skeleton is a type of skeletal system where a fluid-filled cavity (the coelom) provides support and rigidity, allowing for movement through the coordinated contraction of muscles surrounding the cavity. While arthropods are known for their exoskeletons, hydrostatic skeletons are found in some arthropod larvae and during the molting process, but are not the primary form of skeletal support in adult arthropods.

The part labelled I is the ureter which transports the urine from the kidney straight to the bladder where the urine is stored before passing out through the urethra.

Vasectomy, also known as male sterilization, is a highly effective and permanent form of birth control for men achieved by surgically cutting or blocking the vas deferens, the tubes that carry sperm.. The Vas deferens is labelled III

The part labelled I is called the cotyledons. In many plants, the cotyledons are the first leaves to emerge from the seed and can even become photosynthetic, especially in epigeal germination (where the cotyledons emerge above ground). Cotyledons, often called "seed leaves," are embryonic leaves within a seed that store nutrients and provide initial nourishment for the developing seedling, especially before it can photosynthesize. It contains stored food reserves (like starch, fats, and proteins) that are essential for the seedling's early growth and development.

Seed germination can be broadly classified into two main types: epigeal (where cotyledons emerge above the soil) and hypogeal (where cotyledons remain below the soil). Additionally, there's vivipary, where seeds germinate while still attached to the parent plant. The hypocotyl is the embryonic axis below the cotyledons (seed leaves), connecting the root (radicle) to the seed leaves, while the epicotyl is the embryonic axis above the cotyledons, developing into the shoot system.

The part labelled II is the eustachian tube and it's function is to balance or equalize air pressure between the middle ear and the outside environment, ventilate the middle ear, and protect it from nasopharyngeal secretions and sound pressures.

Shivering in a cold environment is a crucial homeostatic response because it's the body's involuntary mechanism to generate heat and maintain a stable internal temperature, preventing hypothermia. Homeostasis refers to the body's ability to maintain a stable internal environment, including temperature, despite external changes. The hypothalamus, a region in the brain, acts as the body's thermostat, monitoring temperature and initiating responses to maintain it. When the body temperature drops, sensory receptors in the skin and brain detect the cold and send signals to the hypothalamus. The hypothalamus responds by triggering shivering, an involuntary muscle activity that generates heat.

Optimal temperature refers to the temperature range at which a biological system, like an enzyme or organism, functions most efficiently. From the graph, the optimal temperature is the highest temperature peak of the curve where the number of cockroaches is highest. Consequently, it is 24\(^0\)C.

The temperature at which cockroaches will not survive after 10 days is 15\(^0\)C because the graph that hits the zero level, which shows all the cockroaches will die after 10days is the curve that has 15\(^0\)C.

Evaporation is taking place in the part labelled I as the ocean is being evaporated to the cloud. Transpiration which takes place in the leaves of the plants is taking place in the part labelled II.

While clouds are a crucial part of the water cycle, acting as a temporary storage location for water, they are not considered the major reservoir in the water cycle; that distinction belongs to the oceans. The oceans are by far the largest reservoir, holding about 97% of Earth's water.

The Mambilla Plateau is located in the southeastern part of Taraba State of Nigeria under Sardauna local government area. The Mambilla Plateau constitutes one of Taraba State's largest local government areas.
