Answer:
Endothermic reaction
Explanation:
Photosynthesis is an endothermic reaction because sunlight is being absorbed during the reaction and the definition suggests that in a reaction if heat is being absorbed it is termed as an endothermic reaction.
Answer: Why?
Explanation: I hope you are okay.
Answer:
The heat given off by Earth's core is circulated through mantle convection.
Explanation:
Heating materials usually causes them to <em>expand</em>; as they become hotter, they also become less dense. Convection describes the transfer of heat from hot areas of liquids and gases to cooler ones. This causes the heated, less dense material to rise and more dense material to fall, as it’s pulled by gravity. Super-heated metal forming Earth’s central core heats rock in the mantle; the hot and cool rock slowly rise and sink- this circulation process is called mantle convection.
Answer:
Sexual reproduction is a mode of reproduction involving the fusion of haploid female gamete (egg cell) and haploid male gamete (sperm cell). The fusion of these gametes occurs at fertilization resulting in the formation of a diploid zygote. ... Two major types of sexual reproduction are syngamy and conjugation.
