The correct answer is - extinction.

When all the members of a species die out, thus disappear from the environment, the species has become extinct.

The reasons for extinction are numerous, but while in the past it has only been because of natural reasons, in recent times it is actually the humans with their activities that contribute to the extinction of the species the most.

There's usually multiple fazes in the decline of a species until it goes extinct, with the last one before extinction being ''endangered'', and from what has been seen so far, once a species reaches that faze, it is almost impossible to recover, but instead it goes extinct.

How does the process of dissolving occur​
andrew11 [14]
Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. This break up is caused by coming into contact with the solvent. In the case of salt water, the water molecules break off salt molecules from the larger crystal lattice.

a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages​
elena-s [515]

Answer:

75years

Explanation:

Let the Father's age be represented by 2x

Let the Son's age be represented by x

Five years ago;

Man's age will be = 2x - 5

Son's age will be = x - 5

If the ratio of their ages five years ago was 9:4, then;

2x - 5/x-5 = 9/4

4(2x - 5) = 9(x - 5)

8x - 20 = 9x - 45

- Collect like terms

-20 + 45 = 9x - 8x

25 = x

Hence, the son's age = 25 years

If x = 25, the father's age (2x) will be 2 × 25 = 50years

The sum of their ages will be = 25years + 50years = 75years
