Hormones and water balance are another two conditions which are maintained by cells.
Explanation:
The half life is the time taken for a half of a radioactive material or substance to decay to half.
After the passing of the half-life, only half of the original material will remain. Now, let us follow the half-life sequence of this decay;
One half-life
Original: 1000cm
one half life = 500cm
Two half-lifes
Original: 500:
half-life = 250cm
Three half-lifes
Original : 250cm
Half life = 125cm
Four half-lifes
Original: 125cm
Half life = 62.5cm
Five half-lifes
Original: 62.5cm
Half-life = 31.25cm
Six half-lifes
Original: 31.25cm
Half-life = 15.625

Answer:
D: fast revolution
Explanation:
As the inner planets rotate around the Sun much faster than the outer ones, the new inner planer would have a fast revolution.
The closer the planet is to the star, the faster is its revolution. Also, the inner planets are smaller, with less density which helps them rotate faster.
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when organisms from one trophic level are consumed by organisms of the next level. More specifically, 90% of metabolic energy is used, so only 10% will be passed down to the next level.
The reason for this change is "Technological advances led to the discovery of single-celled organisms and increased our understanding of relationships between organisms"
<h3>Why bacteria and archaea should be classified into different kingdoms?</h3>
Archea and bacteria are both prokaryotic organisms ( organisms without defined organelles and nucleus) that share common features such as a similar morphology and similar ways to obtain food/energy. However, these organisms have important differences such as RNA type, they have a slightly different morphology and they live in different habitats.
<h3>Why did this change in classification occurred?</h3>
This change occurred due to technological advances. Indeed, the classification of organisms into 4 kingdoms occurred by the beginning of the 20th century when unicellular prokaryotic organisms had not been completely studied, and therefore it has not been determined this group included two sub-groups.
