Meiosis
is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell
Answer:
Frequency is inversely proportional to wavelength.
Explanation:
frequency is the number of oscillations in a unit of time.
Wavelength is the length between one oscillation and the next oscillation.
take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)
Now get two pins and pin them at a certain distance apart.
take the first spring and attach its two terminals to the pins.
Repeat the above procedure, but double (increase the distance x2) the distance between two pins.
Now you have to measure how many coils are there within 5cm of the two springs.
you'll observe that the second spring has half the coils of the first spring within 5cm.
In here no. of coils is the frequency
5cm length is time.
distance between coil is the wavelength.
Causes for ground water pollution are: *Improper on-site disposal of wastewater from domestic holds as well as from industries *Over extraction of ground water in coastal areas causing intrusion of sea water into ground water acquifer *Removal of top soil for construction activities, quarrying of minerals, etc. *Paving ground surfaces preventing rain water to percolate into ground water acquifer and thereby prevention of dilution of pollution in ground water *Improper sealing of wastewater treatment plants without properly determining the permeability of soil strata
The type of clothes you should wear in a labratory is a lab coat and goggles to protect your eyes from harmful chemicals you may use.
