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 />
- <u>The correct answer is the first choice: Factor 1 and factor 2 are considered natural factors.</u>
<h2>Explanation</h2>
The <em>causes of global climate change</em> are those <em>factors</em> that have an impact in our planet's climate. They may be either anthropogenic or natural.
Anthropogenic means generated (<em>induced</em>) by the <em>human</em> being, i.e. by the activities that we the humans perform, e.g. industry, automotive transportation, household waste, deforastation, use of fossil fuels.
<em>Natural causes</em> 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<em> factors</em> stated in the question, <em>volcanic eruptions</em> and <em>changes in the amount of Sun’s heat received by the Earth’s atmosphere and surface are considered natural factors.</em>
Answer: Phosphate head group from A
Explanation: Phosopholipase can also be called Lecithinase. It is an enzyme that in the presence of water degrades or hydrolyzes phospholipids to give fatty acids and other lipophilic substances. There are four major kinds of Phospholipases and they are classified based on the kind of chemical bond which they attach or cleave themselves to. They are; Phospholipases A, B, C and D.
Answer;In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
Explanation:
Answer: Different genes being expressed.
Explanation:
The differences in the structure of the muscle and the nerve cells is due to the gene expression or gene expressed in the cell and the gene silenced to achieve the desired organisation of cells.
