Answer and Explanation:
In homeostatic control processes any deviation from the norm sets into motion the appropriate corrective mechanisms which restore the norm. This rectification occurs through negative feedback. When you go outside wearing a sweater on a hot day, the body sends messages to the CNS and the following occurs:
- The superficial blood vessels vasodilate so that more blood flows near the surface. This encourages heat loss.
- Sweating and panting. Sweat secreted by the sweat glands evaporate from the surface of the body as it absorbs latent heat.
- The metabolic rate falls so that the body generates less heat. You also become less active
- Behavioural response by seeking cooler areas, cold drinks or removal of the sweater.
Explanation:
It is true that the wings of the bee move very fast. The wings are smaller than their body and it is believed to be difficult for the wings to lift the whole body of the bee.

Explanation:
Vascular tissues are conducting tissues formed from specialized cells . The two conducting vascular tissues in plants are xylem and phloem.
Xylem tissue transport water and nutrients from plant roots to all part of the plants. Phloem transport sugars. It also provide structural support for plants. Vascular tissues run through the veins of the leaves and provide support. Vascular tissues are found in vascular plants.
