The planets closest to the star are rocky planets formed by elements with high melting points. Moreover, planets far away are gaseous planets and they are composed of elements with lower melting points.
<h3>Rocky planets and gaseous planets</h3>
The rocky planets consist of silicate rocks and/or metals, whereas gaseous planets are mainly composed of hydrogen and helium.
The rocky planets of the solar system include planets closest to the sun, i.e., Mercury, Venus, the Earth, and Mars.
The gaseous planets of the solar system include faraway planets, i.e., Jupiter, Saturn, Uranus, and Neptune.

The statement that BEST describes the relationship between concentration and enzyme activity is when substrate concentration decreases, enzyme activity decreases (Option B).
- Enzymes are proteins that speed up chemical reactions by lowering the activation energy of that reaction.
- Some factors that alter enzymatic activity include temperature, pH, and substrate concentration.
- An enzyme works in optimum condition as long as there is more substrate available which can be broken down by the specific enzyme.
- However, the enzymatic activity increases as the substrate concentration until a limiting value is reached.
In conclusion, the statement that BEST describes the relationship between concentration and enzyme activity is when substrate concentration decreases, enzyme activity decreases (Option B is correct).

Answer:
A - the four cells have identical DNA sequences.
Explanation:
Essentially all cells in a multicellular organism have exactly the same DNA sequence.
The reason the cells look different is because different genes are active in different cells - which gives them their unique shapes, structures and activities!
Transpiration is the process that releases water from living organisms into the atmosphere.
Hope that helps
The birth and death rates must remain approximately equal in order to maintain a dynamic equilibrium in the population of the Kalij pheasants.
<h3>What is the death rate?</h3>
The death date refers to the number of deaths in a population in a given period of time (usually a calendar year).
Conversely, the birth rate can be defined as the number of population births in the same period of time (a year).
In conclusion, the birth and death rates must remain approximately equal in order to maintain a dynamic equilibrium in the population of the Kalij pheasants.
