Answer:
Monohybrids
Explanation:
Gregor Mendel performed many experiments to discover the principles that governs inheritance. He crossed purebreeding plants with certain traits to obtain offsprings that phenotypically express same traits. The offsprings will be phenotypically identical to one of the parents for that particular trait. This kind of cross is called a MONOHYBRID CROSS and the offsprings are referred to as MONOHYBRIDS.
They are called MONOHYBRIDS because they differ in only one characteristics or trait.
Answer:
<u>Temperature</u> is most likely the reason of protein unfolding (denaturation).
Explanation:
In the figure attached, coiled (3-dimensional) protein structure is changed to 2 dimensional structure in which protein is unfolded. This is most likely the result of heating proteins which destroys the hydrogen bonds and non-polar hydrophobic interactions that are necessary to establish the tertiary structure of proteins. Principally, increased temperature results in the increased kinetic energy of atoms within a molecule. If the amount of heat is sufficient to break the hydrogen bonds, protein molecule can unfold to 2D structure as shown in the figure.
This arrest of division is an example of Density-dependent inhibition. Density dependent inhibition is the process where crowded cells stop dividing; the number of cells in an area force competition for nutrients, space, and growth factors, therefore, when cells are crowded, they get signals to stop dividing. In density dependent inhibition, when density is high there is no cell division and when the density is low cells divide.
Answer:
A group of individuals of the same species occupying a particular geographic area. Populations may be relatively small and closed, as on an island or in a valley, or they may be more diffuse and without a clear boundary between them and a neighboring population of the same species.
Hershey and Chase Experiment
Why are radioactive isotopes a valuable tool in molecular biology? Molecular biology mostly takes place on a scale too small to be directly observed by researchers. While cells, organelles, and even macromolecules can be visualized with high-powered microscopes, the molecular processes that drive biology cannot be seen and need to be inferred from experiments. Radioactive isotopes are versions of elements such as carbon, nitrogen, or phosphorus that unstable and release neutrons to become more stable isotopes. The radioactive signal given off by the emission of neutrons allows scientists to detect the isotopes even when they cannot be seen. Adding isotopes to biological systems allows scientists to trace both molecular pathways and the locations at which these pathways occur.
