Answer:
Option (A)
Explanation:
Here, the given question is based on the scale-model.
a height of 10,000 feet on the actual mountain range is taken equivalent to 1 foot in the model .
so we can write it as,
10,000 feet=1 feet
1 feet=(1÷ 10,000) feet
Therefore,
5000 feet={(1÷ 10,000)×5,000} feet
5000 feet=0.5 feet
So, we can determine that a height 5000 feet on the actual mountain range is equivalent to a height of 0.5 feet on the model.
Hence, the smallest mountain on the model is 0.5 feet.
In the United States, the Clean Air Act is administered by the Environmental Protection Agency (EPA).
The EPA is a federalagency responsible for implementing and enforcing environmentalregulations, including those related to air quality.
The EPA sets national air quality standards, establishes emissions regulations for industries, monitors air quality, and works with state and local governments to implement and enforce air pollution control measures.

Mitochondria and chloroplasts are organelles of a cell possess their own DNA. Thus, option (b) is correct.
In both plant and animal cells, mitochondria are membrane-bound organelles that are essential for producing the chemical energy required for the cell's metabolic processes.
On the other hand, chloroplasts, which are only present in plant cells, are in charge of photosynthesis. Both organelles are involved in protein synthesis and have their own genetic material.
As a result, the significance of the organelles of a cell possess their own DNA are the aforementioned. Therefore, option (b) is correct.

Answer:Cell membrane
Explanation:Forms a boundary between a cell and the surrounding environment and controls the passage of materials into and out of the cell.
Answer:
Cell Membrane (These are from my personal Biology Notes)-
Explanation:
Found in all cells (FIAC)
Selectivity permeable
Embedded with proteins
Regulates what enters or exits the cell
Phospholipid bilayer
Polar: head is hydrophilic (Likes water)
Nonpolar: tail; hydrophilic
