Prokaryartic celldoes not have well organized nucleus

Sia ? 5 years, 11 months ago

Prokaryotic cells (like bacteria) are very simple cells. They lack a nucleus, sometimes called the control center of the cell. In prokaryotic (PRO-care-ee-ought-ick) cells, the genetic material or DNA is loose inside and is made of a single loop.

Viruses as living:

Have genetic material i.e either 
DNA
 or 
RNA
.

Can undergo mutation.

Show irritability.

Are capable to reproduce and hence can increase their number.

React to heat, chemicals and radiations.

Are resistant to antibiotics.

Viruses as non-living:

Can be crystallized.

Are inert outside the host.

Lack cell membrane and cell wall.

Can't grow in size, shape or something like that. Don't possess any sort of nutrients.

Don't respire or breathe & also don't excrete.

Don't undergo their own metabolism.

Lack any energy producing system and are totally dependent on their host for their reproduction and metabolism.

In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed. By cloning a person's own body cells, scientists hope that a cloned stem cell line will not be rejected by the patient receiving the cells. The genetic material will be identical to their own. Cloned cells may one day be used to treat a damaged heart or neurons.

Types of plastics: Plastics are of two types – thermoplastics and thermosetting plastics.

  1. Thermoplastics – Thermoplastics get soft when heated and hard again when they are cooled.  Example – polythene and poly vinyl chloride. Such plastics are used in making toys, containers, plastic bags, raincoats and combs. Thermoplastics are used in making those articles which do not get too hot, and are flexible.
  2. Thermosetting plastics – Thermosetting plastics get soft only one, the first time they are heated after being made. When such plastics are heated for the first time, they become soft and can be moulded to make an article of any desired shape. On cooling, the article becomes hard and rigid. Example – Bakelite and melamine. They are used in making handles of cooking utensils, plates, cups, floor tiles, electrical fittings, telephone instruments, etc.

A) Exhaustible natural resources like coal, petroleum and natural gas are formed from the dead remains of living organisms (fossils). So, these are all known as fossil fuels. B) Aluminum foils are used to wrap food items because aluminum metal is malleable. Therefore, it can be beaten into thin foils. C) Sodium and potassium are stored in kerosene because they are highly reactive elements. They can easily catch fire even when in contact with air. D) A metal can displace a less reactive metal from its salt in an aqueous solution. But zinc is more reactive than copper. Therefore, copper cannot displace zinc from its salt solution. Cu(s) +ZnSO4(aq) ➡️No reaction

(b) Aluminium is malleable, soft and does not react with food items, so it is used to wrap food items (c) sodium and potassium are very reactive metals. They react with air and water but cannot react with kerosene. Both metals are heavier than kerosene so they sink in kerosene. So, sodium and potassium are stored in kerosene (d ) Copper is less reactive than zinc., So, it cannot displace zinc from its salt solution
