What are the reactants of respiration? Anaerobic respiration Aerobic respiration Oxygen Present Oxidation of glucose Complete Reactants of respiration Glucose and oxygen Products of respiration Carbon dioxide and water (and ATP) What are the requirements for respiration? Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy. The reaction […]

How did the development of the HeLa cell line affect society quizlet? The HeLa cells and the situation surrounding them have helped bring attention to the issues of privacy and scientific research within our society. HeLa cells were used to develop chemotherapy treatments for cancer patients. Chemotherapy is now used by more than 500,000 people. […]

Why does natural selection not produce populations that are perfectly adapted to their environment? -Genetic drift, gene flow, and mutation are evolutionary processes that do not lead to adaptation. -There has not been enough time available for natural selection to produce populations that are perfectly adapted to their environment. Changing environments may change the nature […]

What describes the structure of DNA? DNA is the molecule that holds the instructions for growth and development in every living thing. Its structure is described as a double-stranded helix held together by complementary base pairs. The basic units of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. Which statement […]

What are tubers on potato plants? Potatoes are generally grown from tubers known as ‘seed potatoes’. These are sprouted or ‘chitted’ prior to planting, particularly when growing early season cultivars. Chitting or sprouting tubers extends the growing period and leads to earlier tuber formation and higher yields. What type of root system does a potato […]

What evidence was found from soft tissue samples of a remarkably well preserved Tyrannosaurus rex that provided molecular evidence linking T Rex to a chicken? Rex cell structure was found to be similar to the cell structure of chickens. D. T.Rex cells were found to use glucose as a source of energy just like a […]

Which of the following is a renewable form of energy? The most popular renewable energy sources currently are: Solar energy. Wind energy. Hydro energy. Tidal energy. Is natural gas a renewable form of energy? It’s considered renewable because of how easy it is to make, especially compared to nonrenewable energy sources like fossil fuels. So […]

How is the classification system organized? In a classification system, kingdoms, species, and other taxa are typically arranged in a hierarchy of higher and lower levels. Higher levels include taxa such as kingdoms, which are more inclusive. Lower levels include taxa such as species, which are less inclusive. What are the levels of Linnaeus classification […]

Why is it important for a cell to have a large surface to volume ratio? Every cell has a limit of surface area to volume ratio to ensure that the exchange of resources and waste occurs quickly enough for the cell to survive. If cells were too big, diffusion would take an extremely long time, […]

How could data be used to draw conclusions? The purpose of most experiments is to prove or disprove a hypothesis. Scientists do this by collecting data, analyzing it and drawing a conclusion. Scientists have ways to organize their data that make it easier for them to understand the results. Sometimes they use graphs, and sometimes […]
