Explanation

Fossorial means digging or burrowing animals.

Explanation

The part of the ear that primarily belongs to hearing is the Cochlea.

The cochlea is responsible for converting sound vibrations into neural signals that the brain interprets as sound.

Explanation

Leopard seals use their powerful jaws and long teeth to kill smaller seals, fish, and squid.

These effective predators live in frigid Antarctic and sub-Antarctic waters, where they also eat penguins.

They often wait underwater near an ice shelf and snare the birds just as they enter the water after jumping off the ice.

Explanation

Explanation

A foot-pound is a unit of work or energy

Specifically, it represents the amount of work done when a force of one pound moves an object one foot in the direction of the force. 

Physical Quantity/ Unit

Work/Energy: foot-pound (ft-lb)

Force: pound (lb)

Distance: foot (ft)

Explanation

 Bakelite is a thermosetting polymer. 

Thermosetting polymers are plastics that undergo a permanent chemical change when heated,

Forming cross-links that make them rigid and unable to be reshaped or melted after curing.

Bakelite is a classic example of a thermosetting polymer,

Formed through the condensation reaction of phenol and formaldehyde.

It is often used in applications like electrical insulation and handles. 

Explanation

 A hemoglobin (Hb) level below 7 g/dL is generally considered to indicate severe anemia,

Normal range: Varies based on gender, but typically between 12-18 g/dL for adults. 

Moderate anemia: Hemoglobin levels between 8-10 g/dL 

Severe anemia: Hemoglobin levels between 6.5-7.9 g/dL 

Life-threatening anemia: Hemoglobin levels below 6.5 g/dL 

Explanation

The living simple tissue that provides support to the growing parts of a plant is collenchyma.

Collenchyma is a simple permanent tissue.

The cells are thickened at the corners due to the deposition of cellulose, hemicellulose, and pectin.

It provides mechanical support to the young, growing parts of the plant.

Explanation

The molar mass of CaCO₃ is approximately 100 g/mol.

The molar mass of calcium (Ca) in CaCO₃ is about 40 g/mol.

The proportion of calcium in CaCO₃ is  40/ 100 = 0.4

Therefore, in 0.1 g of CaCO₃, the amount of calcium is  0.1×0.4=0.04 g.

Explanation

When taking blood pressure, the cuff should be inflated to a point approximately 30 mmHg above the point where the radial pulse disappears;

This means inflating the cuff until you can no longer feel the pulse at the wrist, then adding another 30 mmHg of pressure.
