Degger [83]

Various species of the flowering plant of the genus <em>Chrysanthemum </em>have 18, 36, 54, 72, and 90 chromosomes. The variation is likely due to polyploidy.

<h3>What is polyploidy?</h3>

Polyploidy can be defined as the number of complete sets of chromosomes in a given cell of an organism.

A diploid organism contains two complete sets of homo-logous chromosomes in its somatic cells.

Many organisms used polyploidy as an evolutionary strategy for adaptation to challenging environmental conditions.

Vitamin D is a fat soluble vitamin that is responsible for fostering the absorption of calcium, magnesium and phosphate in the body.

The synthesis of calciferol is dependent on the availability of a related steroid called cholecalciferol (vitamin D3), which may be synthesized in the skin or absorbed from the diet because keratinocytes of the epidermis and fibroblasts of the skin is response for producing vitamin D3(calciferol) by absorbing it from ultraviolet light when during exposure to UV B photons which protolyses provitamin D3 to pre vitamin D3 in the human body.

It can also be gotten from food sources like milk, cheese, cereals, liver,meat e.t.c.

What kind of data cannot be gathered through remote sensing?
Katen [24]

Movement of surface currents

Explanation:

  • Remote sensing is used to gather data regarding Land use-mapping, weather forecasting, environmental study, and resource exploration.
  • In the case of ocean currents, only satellite remote sensors can determine ocean currents synoptically over coastal regions.
  • SAR(Synthetic Aperture Radar) is also used to determine the ocean currents.
  • The flow patterns of ocean currents are drafted with satellite infrared scanners.
  • Usually, many oceanographers use Radio antenna and high-frequency "Radio detecting and Ranging" for measuring surface ocean currents.
