Answer:
1.The fusion of two gametes in fertilization is Syngamy.
2.Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.
3.A body is said to be in motion when its position changes continously with respect to object taken as an reference point.
Answer:
The fusion of male and female gametes during the fertilization is known as syngamy. The fusion of the sperm cell with the two polar nuclei during the double fertilization is known as triple fusion. 2 When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.3 A body is said to be in a state of motion when it is moving or equivalently its position continuously changes with respect to time.
