How are amino acid sequences used to figure out if two species are closely related?
How are amino acid sequences used to figure out if two species are closely related? Molecular clocks are used to determine how closely two species are related by calculating the number of differences between the species’ DNA sequences or amino acid sequences. These clocks are sometimes called gene clocks or evolutionary clocks. What are the […]
What are the materials needed for photosynthesis?
What are the materials needed for photosynthesis? To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food. What is the photosynthesis equation? The process of photosynthesis is commonly […]
How do valence electrons affect properties?
How do valence electrons affect properties? The number of electrons in an atom’s outermost valence shell governs its chemical properties. Elements react to form a closed shell, corresponding to the electron configuration s2p6 . This tendency is called the octet rule, because the atoms have eight valence electrons. Do valence electrons determine physical properties? Electrons […]

How can you increase the surface tension of water?
How can you increase the surface tension of water? Compounds that lower water’s surface tension are called surfactants, which work by separating the water molecules from one another. Adding salt to water does increase the surface tension of water, although not by any significant amount. … Does sugar increase surface tension water? It has been […]
