Scalar and Vector quantities are Distance and Displacement respectively.
Scalar Quantity is any quantity which has only magnitude but no direction.
It is as follows:
- Distance
- Speed
- Time
- Energy
- Density
- Volume
- Temperature
- Distance
- Work
- Mass
- Frequency
- Direct current
- Entropy
- Refractive index
- Charge
- Electric potential
- Luminous intensity
- Amount of substance
- Pressure
- Power
Vector Quantity is any quantity which has magnitude as well as direction.
It is as follows:
- Displacement
- Force
- Acceleration
- Weight
- Angular Momentum
- Light velocity
- Current
- Gravitational field
- Electric field
- Linear momentum
- Torque
- Polarization
- Centripetal force
- Tension
- Thrust
- Angle
- Drag force
- Impulse
- Alternating current
- Frictional force

Answer:
Explanation:
Haemoglobin in the red blood cells which is one of the components of the circulatory medium, the blood, has a great affinity for oxygen hence transports it around the body during circulation. It is the circulatory system that carries both oxygenated and deoxygenated blood around the body, between the lungs and the heart. The circulatory system takes blood with carbon dioxide to the lungs where oxygen that entered into the body through the nostrils will be exchanged with carbon dioxide in the alveoli. Consequently carbon dioxide will go out of the body through the nostrils via the trachea and haemoglobin in the red blood cells in the blood( blood capillaries) will
carry oxygen which is transported around the body.
Because they no longer have their source of fuel: warm moist air above the sea.
Answer: Option A ,Band C.
Explanation:
Sympatric speciation is the evolution or isolation of new species from the original populations of species occupying in the same geographical area. Sympatric speciation commonly occur due to sexual selection of mates can cause reproductive barriers or isolation which keep gene pools separate. A plant with extra set of homologous chromosomes is an example of sympatric speciation.
