Sweat evaporates, it is through the process of evaporation that heat is taken away from the body and into the surrounding atmosphere
According to model 3. During the child birth the stimulus is baby pushes against the cervix and the response would be hypothalamus oxytocin to male uterine walls contract.
Explanation:
The first contractions of the stimulus (labor) pushes the baby towards the cervix that is the lowest part of the uterus. Normal childbirth is done by positive loop. A positive feedback loop is the change in body status than a return to homeostasis.
One of the best example for positive feedback system is child birth. During labor, a hormone called oxytocin is released which intensifies and speeds up contractions.
Child birth will eventually stop the stimulus and stop the child birth feed back loop.
Answer:
down below
Explanation:
The Sun, Moon, planets and stars make circles around the Earth. Since the observer is tilted with respect to Earth's rotation axis, the daily motion also appears tilted. In the Northern Hemisphere, the stars move to the south as they rise, while stars move northward in the Southern Hemisphere as they rise.
Answer:
The correct answer is a. carnivores.
Photosynthesis is the process by which plants make their food from carbon dioxide and water in the presence of sunlight and chlorophyll. Hence, they convert light energy into chemical energy (food or glucose).
This energy is first utilized in the cellular respiration and then the rest in transferred to the primary consumers i.e. herbivores which feed on green plants.
They use this energy in their metabolic processes. The rest is transferred to the secondary consumers i.e. carnivores which feed on the herbivores.
Hence, energy from the photosynthesis indirectly passes to the carnivores via herbivores.
Answer:
<em>The correct option is d) once the electrical impulse reaches a certain level of intensity (its threshold), it fires and moves all the way down the axon without losing any intensity.</em>
Explanation:
In the field of biology, the all-or-nothing law can be described as a principle which focuses on the strength with which a nerve or muscle fibre responds to a particular stimulus, this strength being independent of the strength of the stimulus. The functioning of the impulse is just like the trigger of a gun. The more the force of a stimulus, the more will be the intensity of the nerve impulse.
