C. Condensation.

Boiling, evaporating, and melting all lose energy because that liquid is becoming less. For instance, water melts or could be boiled then it would evaporate. What happened to the water? It loss it's energy to continue to stay as water.

Condensation brings water back. That requires energy. Hope this helps!

Which of these statements is correct about the two factors which cause global climate change? (2 points)

Goshia [24]

The complete question is:

Two factors which cause global climate change are listed below.

Factor 1: Volcanic eruptions.

Factor 2: Changes in the amount of Sun’s heat received by the Earth’s atmosphere and surface.

Which of these statements is correct about the two factors which cause global climate change?

Factor 1 and Factor 2 are considered natural factors.

Factor 1 and Factor 2 are considered human induced factors.

Factor 1 is a human induced factor and Factor 2 is a natural factor.

Factor 1 is a natural factor and Factor 2 is a human induced factor.

<h2>Answer</h2><h2 />

The correct answer is the first choice: Factor 1 and factor 2 are considered natural factors.

<h2>Explanation</h2>

The causes of global climate change are those factors that have an impact in our planet's climate. They may be either anthropogenic or natural.

Anthropogenic means generated (induced) by the human being, i.e. by the activities that we the humans perform, e.g. industry, automotive transportation, household waste, deforastation, use of fossil fuels.

Natural causes are product of the nature's cycles or events, such as the amount of energy that the Sun radiate, the volcanic activity, the natural cooling and warming of the air from the ocean, and glacial changes due to ice ages.

Hence the two factors stated in the question, volcanic eruptions and changes in the amount of Sun’s heat received by the Earth’s atmosphere and surface are considered natural factors.

Juliette [100K]

Explanation:

This would be an example of secondary homeostasis

During wound healing, which happens after bleeding from a cut, the homeostatic response is clotting; primary homeostasis involves the formation of a platelet plug at the site, from platelets within the blood

Fibrinogen and platelets form a clot, in order to prevent blood loss and infection. Fibrin is formed through the activation of coagulation factors which stabilise the plug.

Further Explanation:

The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.

The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system; and the autonomic nervous system (ANS) which regulates involuntary bodily functions like heartbeat, breathing and blood flow. The ANS is mainly acts unconsciously and affects smooth muscle and internal organs. It is related to homeostasis- where the body maintains a constant internal balance in pH, temperature, blood pressure etc.

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.
