Answer:
the smallest star right now is the red dwar star which is also called OGLE-TR-122b with a radius of 0.12 solar radii
the largest star is UY Scuti it is roughly 1700 times larger than the sun
Explanation:
Answer:
Radiometric dating is usually defined as a method that helps in calculating the age of rock depending on the presence of radioactive isotopes and its rate of decay. In order to calculate this, the half-life of the isotope element must be known. This method is commonly used by geologists.
The conditions that are needed to fulfill in order to determine the age of a granitic batholith are as follows-
- The rate at which these materials decay must be a constant
- There should be an exact amount of both the parent as well as the daughter elements.
- Since it is a batholith, so it has formed from the crystallization of magma at a certain depth. So, these granitic rocks must have remained within a closed system, right from the time of its formation.
The various methods of radiometric dating that can be used to date this granitic batholith are-
- Uranium-lead dating- It is an efficient method to date the rocks that are of about 4 to 4.5 billion years.
- Potassium-argon dating- It is also commonly used to date rocks that are about 4 billion years old.
Answer:
The true statement is - Sympatric speciation only occurs in areas where there is local variation in environmental resources
Explanation:
- Sympatric speciation means the evolution of new species from an ancestor species which are occupying in the same area and no geographical barrier takes place.
- Overlapping of ranges takes place to the organism and old and new species are living i the same geographical region.
- A dam diving a fish population could lead to allopatric speciation where geographical barrier causes formation of new species which are completely different from their ancestor species.
