Explanation

 In the human body, there are 3 pairs of false ribs on each side, corresponding to the 8th, 9th, and 10th pairs of ribs.

These ribs do not directly connect to the sternum (breastbone) like the true ribs (pairs 1-7).

Instead, their cartilage connects to the cartilage of the 7th rib, which is a true rib. 

Explanation

The process in which the change of vapor or gas into liquid is known as condensation

Some examples of water condensation:

• Morning dew on the grass.
• Water droplets on the outer surface of cold drink bottle.
• Foggy car windows

Additional information:

The process of change of state from solid to liquid is called melting

Evaporation is the conversion of liquid into its vapor, below the boiling point of liquid.

Explanation

A respiratory surface, such as the alveoli in lungs or the surface of gills, possesses the following properties:

• Thin: allows for efficient gas exchange
• Wet: facilitates the exchange of gases between the surface and the surrounding environment
• Permeable: allows gases to pass through the surface
• Very large: provides a large surface area for gas exchange to occur

Explanation

 The bronchioles are small branches of the bronchi, and they eventually end in tiny air sacs called alveoli where gas exchange occurs. 

Explanation

Diamond is a covalent network crystal.

It's composed of carbon atoms covalently bonded to each other in a three-dimensional tetrahedral lattice. 

Explanation

Transverse waves involve oscillations perpendicular to the direction of travel and can be polarized, while they do not necessarily require a medium to travel (e.g., light waves).

Explanation

 Phylum Chordata is divided into three subphyla.

• Urochordata (Tunicata)
• Cephalochordata
• Vertebrata 

Explanation

In the dark reaction (also known as the Calvin cycle), the first stable compound formed is 3-phosphoglyceric acid (3-PGA), which is a three-carbon compound.

Hence, the correct answer is c) 3. 

Explanation

 In Einstein's universe, the fourth dimension is time. 

Einstein's theory of relativity revolutionized our understanding of space and time, merging them into a single four-dimensional continuum called "spacetime".

Time is considered the fourth dimension within this framework. 

Explanation

A metastable state is an excited state of an atom or molecule that has a significantly longer lifetime compared to other excited states, but is still shorter than the ground state.

This means that an electron in a metastable state can stay in that state for a relatively long time before transitioning back to a lower energy level.
