When a person is jogging, the body sends hormones that continually decrease the rate of oxygen supply to the legs

Answers

Answer:

The statement - When blood sugar is too low, the body sends hormones that raise blood sugar until it reaches a typical level and hormone secretion slows, describes a negative feedback loop.

Explanation:

In the human body, the term homeostasis means the tendency of the various systems in the human body to stay in optimal ranges for health by self regulation through feedback controls. It is very important because it maintains equilibrium and provides stability to the human body. A negative feedback loop (inhibitory loop) is a type of self-regulating system in which increased output from the system inhibits the future production by the system. Example of negative feedback to achieve homeostasis are blood pressure, body temperature,  blood sugar. In blood sugar regulation, the hormone insulin lowers blood glucose when levels are high and the glucagon increases blood glucose when levels are low. In a positive feedback system, the output amplifies the original stimulus. Examples of a positive feedback system are child birth, lactation, blood clotting etc. During child birth, the hormone oxytocin released increases and speeds up the contractions.

What is it about the life-cycle that makes cane toad populations successful?

Answers

Life-cycle - Cane Toad Population Successful

The water of any nature is essential for survival and reproduction. Cane toad can produce eggs ranges from 8,000 to 35,000 at a time. There are two conditions for healthy development which are described as follows:

  • The slow flowing water must be avaible for the toad.
  • 25-30 degree C temperature is needed for healthy development.

In this way, cane toads make population successful during the life cycle.

Cane Toads are very strong and adaptable, they are also poisonous throughout its life cycle, which is why they only have a few predators and have a life span of 10-15 years. Cane toads have poison glands, and the tadpoles are extremely toxic to most animals if consumed. They are productive breeders, they only need a small pool of water of almost any nature. The female cane toads can lay 8,000 to 35,000 eggs at a time and may produce two clutches in one year. The eggs will hatch within 24-72 hours and the tadpole stage may last from three to twenty weeks. Cane toads in the tropics grow really quick and may be sexually mature only within one year. Cane toads have been introduced to many regions of the Pacific and the Caribbean islands as a method of agricultural pest control because of their ravenous appetite, however, they are now considered pests and are dangerous to humans and animals, both wild and domesticated especially to dogs.
