Explanation:
c. cell wall, vacuole
Among the choices above, the two features that indicate that a cell is a plant cell is the cell wall and vacuole. The cell wall can only be found in plant cells. It is the rigid cell that surrounds the cell membrane. The vacuole of a plant cell and animal cell are way too different. The vacuole of an animal cell is usually more than one and small, even smaller that that of the plant cell. On the other hand, the vacuole of the plant cell is only one in fact a large one that takes up almost 90 percent of the volume of the cell
Answer:
1. When a rubbed ruler is brought close to the paper, salt and pepper they are not equally attracted as paper is lighter than pepper and salt, so it takes less effort for paper to overcome the force of gravity.
2. electrostatic induction is a phenomenon in which static electricity is generated in an object by bringing an electrically charged object near it. When a charged object is brought near to an uncharged body it causes electrical charges to redistribute in the body, resulting one side having excess of positive charges and other side having negative charges, as a result body become charged. Electrostatic interaction also depends upon the nature and mass of body.
b. the combination of fur cloth and rubbed ruler produce greatest effect. The reason is that when ruler is brought near to fur excess of electron will flow into fur.
Answer:
A. volcanic ash layers were regularly interspersed between the sedimentary strata.
Explanation:
The discovery of a fossil is a moment of accomplishment for archaeologists, hence the date dating process begins and the older the relic the greater its value for paleontology. Chemistry is present in this process, more precisely the carbon element, but other elements can be used as uranium, lead, potassium and argon.
In the case of the fossils reported in the question, to assign absolute dates to fossils in this sediment core would be most useful if volcanic ash layers were regularly interspersed between sedimentary strata because it would separate sedimentation times and allow the use of more than one element. dating, making the search more complete and the date most credible.
