5 Facts about cell division
julia-pushkina [17]

Answer:

Cell division is the process by which a cell, called the parent cell, divides into two cells, called daughter cells.[1] When the cell divides, everything inside it divides also. The nucleus and the chromosomes divide, and the mitochondria divide also.

In mitosis, an ordinary body (somatic) cell divides to make two daughter cells.

In meiosis, a cell divides twice, to produce four gametes (sex cells). The first division of meiosis is a special kind of cell division called a reduction division because the number of chromosomes is halved. The second division of meiosis is similar to mitosis.[2]

Three types of cell division: left is binary fission as in bacteria; right are mitosis and meiosis as in eukaryotes.

Cells are the 'building blocks' of life, and cell division is a basic feature of life. For simple unicellular organisms like Amoebozoa, one cell division reproduces the entire organism. On a larger scale, cell division can create offspring from multicellular organisms, such as plants that grow from cuttings. But most importantly, cell division enables organisms that are able to sexually reproduce to develop from the one-celled fertilised egg (zygote). Cell division also allows for continual renewal and repair of the organism.

Calculate the mass percent for all components in a solution containing the following. 0.350 Kg of water, 5.4 moles of ammonia an
Alina [70]

Answer:

  • % Water = 54.96%
  • % Ammonia = 0.14%
  • % Cobalt (II) Nitrate = 30.62%

Explanation:

To calculate mass percent, first we need to <u>calculate the total mass of the mixture</u>:

  • Mass Water ⇒ 0.350 kg Water = 350 g water
  • Mass Ammonia⇒We use ammonia's molar mass⇒5.4 mol * 17 g/mol =  91.8 g
  • Mass cobalt (II) nitrate ⇒ 195.0 g

Total Mass = Mass Water + Mass Ammonia + Mass Cobalt Nitrate

  • Total Mass = 350 g+ 91.8 g+ 195 g = 636.8 g

To calculate each component's mass percent, we divide its mass by the total mass and multiply by 100:

  • % Water ⇒ 350/636.8 * 100% = 54.96%
  • % Ammonia ⇒ 91.8/636.8 * 100% = 0.14%
  • % Cobalt (II) Nitrate ⇒ 195/636.8 * 100% = 30.62%
