Answer: fossils can be formed only when a living thing is buried soon after it dies. If it is not buried soon enough, it decays. For this reason, most fossils are found in sedimentary rocks that were once under water.

Answer:
By panting or breathing heavily.
Explanation:
<em>An ectothermic animal is one whose body temperature depends on the temperature of the external environment.</em>
The body of ectotherms regulates temperature depending on the temperature of the external environment where such animal finds itself.
Hence, when the temperature of the external environment rises as a result of hot air, the body of an ectotherm (that is homeothermic, that is, maintain a relatively constant body temperature irrespective of the temperature of the external environment) will adjust so as to keep its temperature relatively constant.
Dogs generally pant (breathe heavily) to bring their body temperature back to normal whenever it rises beyond normal due to rigorous physical activities or high external temperature.
<em>Hence, a fox will most likely pant in response to hot air temperature just like dogs.</em>
The correct answer is option C. Endocrine glands secrete hormones into the bloodstream because endocrine glands are ductless and the exocrine glands have ducts so they secrete their hormones into the ducts.
Answer:
Wakefulness and sleep.
Explanation:
Hypothalamus may be defined as the small region of the brain that maintains the homeostasis of the body. The hypothalamus is divided into anterior hypothalamus and posterior hypothalamus.
The anterior hypothalamus of the brain is involved in the sleep activity of the organisms and releases the hormones also. The posterior hypothalamus is involved in the wakefulness of the individual.
Thus, the correct answer is wakefulness and sleep.
