Why is elephant ivory so valuable? Q: What makes ivory so precious? It has no intrinsic value, but its cultural uses make ivory highly prized. In Africa, it has been a status symbol for millennia because it comes from elephants, a highly respected animal, and because it is fairly easy to carve into works of […]

What processes are anaerobic? Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration. There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation. Does glycolysis require oxygen? Glycolysis requires no oxygen. It is an anaerobic type of respiration performed by all […]

Is O2 a compound? The oxygen molecule O2 is considered a molecule but not a compound. Is air an element compound or mixture? Air is a mixture but not compound. Its constituents can be separated. For example: oxygen, nitrogen etc. What is C element or compound? Carbon is a chemical element with symbol C and […]

Why are digestive enzymes in a cell enclosed in a membrane-bound organelle? It contains ALL the instructions for everything the cell does. Determine why digestive enzymes in a cell are enclosed in a membrane-bound organelle. The membrane keeps the digestive materials from leaking out into the cytoplasm and destroying the cell. Discuss how cells, tissues, […]

Are scientific facts absolute? “Fact” in a scientific context is a generally accepted reality (but still open to scientific inquiry, as opposed to an absolute truth, which is not, and hence not a part of science). Hypotheses and theories are generally based on objective inferences, unlike opinions, which are generally based on subjective influences. Is […]

Does the temperature of water affect buoyancy? As temperature of liquid increses it’s density decreases and hence buoyant force also decrease and vice versa… increasing water temperature causes water molecules to spread further apart, in turn reducing upthrust, and allowing a floating object to displace more water as its buoyancy is reduced. Does buoyant force […]

What effect do abiotic cycles have on ecosystems Brainly? Abiotic cycle determine the survival of biotic components because it plays a major role in recycling of materials for food reservoir and the climatic state of the surrounding. Therefore, when there are fluctuations, the living organisms will suffer from food shortage and climate condition. What are […]

What molecule has more energy ATP or ADP? Thus, ATP is the higher energy form (the recharged battery) while ADP is the lower energy form (the used battery). When the terminal (third) phosphate is cut loose, ATP becomes ADP (Adenosine diphosphate; di= two), and the stored energy is released for some biological process to utilize. […]

What macromolecule is insoluble in water? Lipids What do we call organic molecules that are insoluble in water are often found in cell membranes and have the ability to store energy for long periods of time? Nucleic acids Which macromolecule is insoluble in water and a major component of the cell membrane? phospholipids What macromolecule […]

How can populations change in size? How Does a Population Grow? A change in the size of a population over a given period of time is that population’s The growth rate is the birth rate minus the death rate. Over time, the growth rates of populations change because birth rates and death rates increase or […]
