Answer:
Density-dependent factors are defined as the biological factors which are utilized by the population as a resource for example- food and shelter. Charles Darwin uses the concept of density-dependent factors in his Theory of Evolution to show how it affects population growth and mortality.
Charles Darwin used factors like competition, predation, and parasitism in his Theory of Evolution. He explained that habitats are limited by space and resource availability, and only the fittest organism will survive the competition.
Predator-prey relationships create density-dependent limiting factors and balance the ecosystem with limited organisms. If predators will increase in an ecosystem it will decrease the population of prey and after a certain time there will be a shortage of food as they are limited resources.
 
        
             
        
        
        
Answer:
Assuming you mean in a compound of elements: A name is just what you call it, and the chemical formula is what elements it is made of.
Explanation:
Take sodium chloride (Salt) for example. It's name is sodium chloride, but its chemical formula is NaCl. Na= Sodium, and Cl = Chlorine. So one sodium ion and one Chlorine ion create NaCl. Na+Cl=NaCl. And the name for the product of the formula is Sodium Chloride. 
Another example is H2O (Water). H=Hydrogen and O=Oxygen. There are 2 hydrogens and one oxygen in H2O. H+H+O=H2O. The name for the formula is water.
 
        
             
        
        
        
Germination is a process where plants and other organisms emerge from gymnosperm/angiosperm seeds and start their growth. Gymnosperms are seeds that are not protected by an ovule. Angiosperms are vascular plants that grow fruit and flowers, which are protected by ovule. Sprouting of a seedling from a seed is an example of germination. Fully developed seeds contain an embryo, that store food reserves and are wrapped in the seed coat. Some factors of successful germination include water, oxygen, temperature, type of soil, and light intake.
 
        
             
        
        
        
We need to have sunlight because without it you wouldn’t be able to make anything else
