Answer: When the starfish had been eliminated from the location as a part of an experiment, the mussel populace swelled and crowded out different species. The biodiversity of the environment turned into notably reduced. Payne's look at confirmed that figuring out and shielding keystone species can assist hold the populace of many different species.
Answer: C. Vacuoles are larger in plant cells than in animal cells.
Vacuoles are storage organelles that are found in both animal and plant cells. They store food or any other forms of nutrients, they also store waste products so as to protect the contamination of the cell environment. These waste products are sent out of the cell via vacuoles. In plants the vacuoles are larger than in animals. The vacuole provides plant nourishment in the scarcity of water in the external environment hence, prevents the wilting of plants.
Answer:
Explanation:
Structural determination is a process that use analytical technique to describe in detailed the three dimensional positional coordinates of the scattered centre in an ordered Crystal lattice.
The techniques used are;
X- Ray crystallography, it usese the X-ray diffraction pattern. The structures to be determined by this is first of undergo purification and crystallisation, it is then expose beam of X-ray, which then diffract. It provide detailed atomic information of the structure.
NMR spectroscopy is can be use to determine the structure of protein. The structure to be determined is first of all purified, it is then exposed to strong magnetic field and radio waves. This method supply detailed information of protein in solution.
3D Electron microscopy is used to determined the 3D structures of bigger macromolecules. It uses beam of electron and lenses to show the image of electrons directly.
The biologist is the person who would be interested in determining the existence of any pattern or characteristics with in a species and relate it to the characteristics possessed earlier by the species.
