Cells are the basic units of life. They can exist by themselves, like bacteria, or apart of a larger organism, like our cells. Viruses are non-living infectious particles that are much smaller then a cell, and need a living host to reproduce. They cannot reproduce outside of a living host cell, nor can they be seen without an electron microscope.

The viruses are the submicroscopic infectious agent. The viruses have RNA or DNA as their genetic material covered with the proteinaceous capsid. They do not have their replication machinery hence they are unable to reproduce without the host cell. They are considered as non living without the host cell. It can infect the host cells and reproduce with the utilisation of cellular machinery and energy. The viruses do not have to maintain homeostasis. Hence they are considered as the connecting link between the living and non living world.

In the living cells the genetic material is DNA only not RNA. The living cells have their own cellular machinery to multiply and growth. Hence they are self reproducible. They can metabolise to produce and consume energy. The living cells can also maintain homeostasis.

Heat Transfer discussion based question

lilavasa [31]

Answer: Thermal energy flows from a warmer material to a cooler material. When thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three ways heat is transferred into and through the atmosphere: Radiation, conduction and convection.

Radiation is when energy, in the form of electromagnetic radiation, is emitted by a heated surface in all directions and travels directly to its point of absorption at the speed of light; thermal radiation does not require an intervening medium to carry it. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.

For larger distances such as the distance between objects in the far reaches of our galaxy astronomers ensure in units of?

Scorpion4ik [409]

Answer:

Lightyears

Explanation:

When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.

Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.

This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km

If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.
