Answer:
Withering is a process in which a rock gets broken down into small and large fragments which are displace other location by the action of wind, water and ice. There are three types of withering: mechanical ,chemical and biological. Mechanical withering is a process which brings changes into physical structure of rocks like large rocks are converted into small rock. Chemical withering is a process which brings changes in the chemical composition of rock. This withering process can change minerals content in the rock. Biological withering is a process in which living beings uses rock for their survival like plants, animals and microbes causes disintegration of rock.
Highly withered and unwithered rock can be distinguished by following characteristics:
1. Physical structure: There will be no change in the structure of unwithered rock but structure of highly withered rock will change after the withering process.
2. Chemical composition: The withering process will remove surface and internal minerals present in rock. In unwithered rock the surface and internal mineral composition will remain unchanged but in highly withered rock the surface and internal minerals present in rock will be removed, which change the overall chemical composition of the rock.
Answer:
heterotrophs survive through respiration, using oxygen and an energy source (carbohydrates, fats or protein) to produce ATP, which powers cells. They depend on other organisms for food and oxygen. Photosynthesis benefits heterotrophs in several different ways. First, "photosynthesis consumes carbon dioxide (a waste product of respiration) and produces oxygen (necessary for respiration)." Heterotrophs therefore depend on photosynthesis as a source of oxygen. In addition, "photosynthesis sustains the organisms that heterotrophs consume in order to stay alive. Even if a heterotroph is strictly carnivorous and does not eat plants, it must eat animals that eat plants to survive."
Answer:
Hydrogen
Explanation:
Elements that have low ionization energies tend to have low electronegativities. The nuclei of these atoms don't exert a strong pull on electrons. Similarly, elements that have high ionization energies tend to have high electronegativity values. The atomic nucleus exerts a strong pull on electrons.
