The answer is c) Organisms are multicellular and undergo photosynthesis!
Answer:
The given situation is an example of <u>density dependent factor</u>.
Explanation:
The density dependent factors are the factors that regulate the growth of a population. It is defined as the factors whose effects on the growth or size of a given population vary with the population's density. The various types of density dependent limiting factors are diseases, migration, safe drinking water, food availability, migration etc.
<u>Therefore, the given situation is an example of density dependent factor.</u>
Answer:
• Increase temperature
• Increase concentration-Increase concentration of the Silver nitrate or of the copper.
• Increase surface area-Grind the copper into powder of break it up into smaller pieces.
Answer:
cellular level of organization
Explanation:
The three changes of state during which energy is absorbed are:
1. Change from solid to liquid - Melting.
2. Change from liquid to gas - Vaporization
3. Change from solid to gas - Sublimation
All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.
