The correct answer is Taxon.

Taxon - a unit of classification; element taxonomy group classification level taxonomic rank used in the biological classification. The concept is used mainly in biological taxonomy, where the group of organisms taxon understand, united on the basis of generally accepted methods of classification, interconnected by a degree of kinship, and sufficiently isolated from other groups that it could assign certain taxonomic category ( taxonomic rank) - species, genus, family, and so on.

Classifying things by observation can best be done by using a  : Taxon

Taxon divided organisms into different groups based on their unique similarities, and these similarities can be recognized by observing parts and behavior of the organisms. For example, Organisms generally divided into two groups. Those who have a backbone (vertebrata,  such as mammals and reptiles ) and those who don't have backbones (such as arthropoda)

This is the best way to classifying the organisms because the similarities between them do not exist in their backbones alone. This give more room/possibilities for the classification. For example, The organisms could also be classified by other similarities (such as how they obtain food, their body structure, how they reproduce, etc)

A 6,000 kg train car is moving to the right at 10 m/s and connects to a 4,000-kg train car that wasn't moving. What is the veloc
SIZIF [17.4K]

6 m/s

This type of collision is a <u>Inelastic collision </u>

Explanation:

We begin by finding the momentum of the initial train car;

Remember that momentum is given by the formulae mass (kg) * velocity (m/s)

Therefore;

Momentum = 6000 * 10

= 60,000 kg⋅m/s

The other car has zero momentum because;

4000 * 0

= 0

When the two train cars collide, the total momentum will be;

60,000 + 0 = 60,000

Therefore to find the velocity, well use the same formulae;

p = mv  whereby;

p – momentum

m – mass

v – velocity

60,000 = (6000 + 4000) * v

v = 60,000 / 10,000

v = 6

= 6 m/s

This is an elastic collision because we are assuming that no energy is lost in the collision. Most collisions, however, are not elastic but rather inelastic. In inelastic collision some of the kinetic energy is lost to the environment in some other form of energy such as heat energy.

Summarize the nitrogen cycle and it’s importance of proteins and DNA
iren2701 [21]

Answer:

Nitrogen cycle works through various stages like, nitrogen fixation, nitrification, assimilation, ammonification, denitrification etc. It is a building block for protein and DNA

Explanation:

Nitrogen is an element abundantly found in the atmosphere, also its building block for proteins as well as nucleic acid i.e. DNA formation. In nitrogen cycle , the nitrogen is being prepared from inert nitrogen.  The nitrogen cycle has several processes like nitrogen fixation, in this the inert nitrogen is being converted to organic nitrogen with the help of certain micro-organism.

Nitrification, plants cannot absorb directly nitrogen so bacteria help the plants to convert the nitrogen into ammonia form in this stage. Assimilation, another stage in which plants starts absorbing various forms of nitrogen from the soil.i.e. nitrate, nitrite and ammonium. Ammonification, here plants and animals have nitrogen in there body after death various microbes help in decomposition in this stage. Denitrification, in this stage the return back of nitrogen takes place.
