E = ½mV² → V = √(2E/m)

The mass of a 1 N weight (on earth) is 1/9.8 kg

Ergo,

V = √(2*1/(1/9.8)) = √19.6 = 4.43 m/s

Why is the number of chromosomes halved?

The normal cellular genetic complement number 2N is reduced to 1N in both of the sexual gametes so that when they recombine we end up with the standard chromosome number [1N + 1N = 2N] in our zygote.


Why does meiosis result 1N cells rather than 2N cells?

During meiosis chromosomes are segregated at Anaphase I stage , this results in reduction in number of chromosomes from 2N to 1N .


How many chromosomes does a sperm cell have at prophase I?

Sperm are all 1N (half the complement of chromosomes of the original male). Prophase 1 in meiosis the cell is 4N Prophase 2 in meiosis the cells are 2N Final division creates 1N cells.


One gamete is formed during what process?

The cellular chromosome number is reduced from 2N to 1N.


What is a haploid daughter cell?

Haploid and Diploid refer to the fraction of genetic information a cell contains. Almost all the cells in the human body are diploid (2n) because they contain all of the genetic information of the individual of which they are a part. Gametes (sperm and ova), however, are haploid (1n) because they only contain one half of the total genetic information of the cell they were spawned from. This is why a sperm (1n) and an ova (1n) must fuse to create a new individual (2n). Some simple organisms (such as some yeasts) can exist as 1n or 2n depending on what part of their life cycle they are on. So a diploid cell can undergo a process (called meiosis) to make four haploid daughter cells (it is four haploid cells and not two haploid cells because each adult cell will have two copies of the chromosome from the mother and the father before division).

What word or symbols formula that will convert pounds to newtons?

Weight in Newtons = Mass in kg x gravity in metres/(second squared) so 1N = 0.1kg as 1kg = 2.2lb We get 1N = 0.1kg = 0.22lb (or in reverse, 1 lb = 4.5N)

What is meant by 'OA' in OA79 and '1N' in 1N4001?

IN IN = 1N: Refers to the number of junctions (1N= 1 junction). O= Germanium, A= rectifier diode, so OA = germanium rectifier diode.
