Answer:
Most familiar is biparental reproduction (sometimes called dioecious reproduction). ... Dioecious reproduction leaves the greatest genetic variability among offspring (an advantage under changing conditions or in competition or when faced with disease), but the organisms must find mates.
Answer:
The small opening present on the epidermis which helps with exchange of gasses and transpiration is called stomata. Since most of the water (90%) is lost through stomata it regulates the level of excess water in the plant.

As Jerry nears the campfire, he is delighted at the warmth it provides. Jerry perceives this temperature because of thermoreceptors in his skin.
<h3>What are thermoreceptors?</h3>
- The receptive part of a sensory neuron, or more precisely a non-specialized sense receptor called a thermoreceptor, is responsible for coding absolute and relative changes in temperature, primarily those that fall within a safe range.
- Warmth sensors are assumed to be unmyelinated C-fibers in the mammalian peripheral nervous system (low conduction velocity), whereas cold receptors have both C-fibers and sparsely myelinated A delta fibers.
- Warm receptors respond well to warming, which causes them to discharge action potentials more quickly.
- For cold sensors, cooling causes an increase in firing rate whereas warming causes a reduction.
- A paradoxical reaction to heat is when some cold receptors react to high temperatures, usually above 45 °C, by releasing a short action potential.

Heyo. c:
The only way for gases to diffuse in and out of the leaf is through small openings on the underside of the leaf, the stomata. These stomata can open and close according to the plant's needs. The tissues of the leaf inbetween the epidermal cells, into which gases diffuse from the stomata, are called mesophyll.
