Observing population directly gives you accurate result .
Direct observation does not need any intermediary as they themselves go for survey.
So, it is cost efficient.
Whereas indirect observing may involve manipulations.
It requires someone or many to hire who helps in surveying.
It incurs cost.
Thus, direct observation is always better than indirect observation.
That is called A. <span>Circular distribution.</span>
Answer:
Direct relationship.
Explanation:
There is direct relationship between the temperature of internal material and volcanic eruptions because the temperature of internal material causes the volcanic eruptions. The temperature of the internal material puts pressure on the rocky surface and the gases that releases from heating processes will cause pressure which leads to the eruption of the volcano so we can say that there is a direct relationship between temperature and eruption.
All of the above- 1, 2, and 3 These introduce variation into the chromosome or into the zygote and create cells and offspring unique from the parents.
Answer:
The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.
