What is the definition of Darwinism? 1 : a theory of the origin and perpetuation of new species of animals and plants that offspring of a given organism vary, that natural selection favors the survival of some of these variations over others, that new species have arisen and may continue to arise by these processes, […]

What is the last stage in protein synthesis? When the stop signal on mRNA is reached, the protein synthesis is terminated. The last amino acid is hydrolyzed from its t-RNA. The peptide chain leaves the ribosome. What determines the end of protein synthesis? Proteins are long chains of amino acids , and the exact sequence […]

What happens when water flows into a plant cell? When the plant cell is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become “turgid” i.e. swollen and hard. The pressure inside the […]

How do plants prevent wilting? To prevent wilting, repot plants in larger containers as the plants grow. Excess fertilizer salts may form a white crust on plant containers or soil and cause wilting. Run water through the soil to leach out excess salts, or repot a container plant in new soil. Which process allows plants […]

What do you understand by stimuli? A stimulus causes an action or response, like the ringing of your alarm clock if you didn’t sleep through it. Stimulus is a word often used in biology — something that causes a reaction in an organ or cell, for example. For more than one stimulus, use stimuli, not […]

What connects free floating nucleotides? DNA replication takes place during the S stage of the cell cycle. The unzipping exposes the bases on the DNA strands and enables free-floating nucleotides to pair up with their complementary bases. DNA polymerases bond the nucleotides together to form new strands that are complementary to the original template strands. […]

What two atoms make up oxygen? Two hydrogen atoms and one oxygen atom are bonded together to create a water molecule. Oxygen gas is made up of two oxygen atoms bonded together. O2 is the symbol for an oxygen molecule. What is a molecule made of 2 atoms called? Compounds contain two or more different […]

What is the basic unit of hereditary information? A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. What can be defined as a basic unit of hereditary information that influences a particular trait or group of traits? […]

Which headline is an example of Clickbait? ‘This Is How…’ Again, the goal here is to not be too cryptic, otherwise, readers might get frustrated by your obviously clickbait-y title. Some good examples of headlines in this format include: “This is how business owners are saving thousands on their taxes” “This is how parents can […]

What kind of bond is formed between two hydrogen atoms and the single oxygen atom? covalent bonds Did you know a water molecule consists of two hydrogen atoms and one oxygen atom? A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the […]
