Answer:In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.

Answer:
<em>7.45 10^5N.</em>
Explanation:
according to newtons second law of motion;
Fapp is the applied force
Fr is the resistive force
m is the mass of the luxury
a is the acceleration
Since the huge luxury liner move with constant velocity, then acceleration is zero i.e a = 0. The equation becomes;
This shows that the applied force will be equal to the resistive force if the velocity is constant.
Given Fr = 7.45 10^5 N therefore the resistive force will also be 7.45 10^5N.
<em>Hence the magnitude of the resistive force exerted by the water on the cruise ship is 7.45 10^5N.</em>
Answer:
The Height of a pyramid is 4r.
Explanation:
Explanation is in the following attachments
The intensity of an electromagnetic wave increases with the field strength.
Only Condition for Resonance is-
It occurs when the first object is vibrating at the natural frequency of the second object. It always result into a big vibration/loud sound.
Resonance is process by which a vibrating system or an external force drives another system to oscillate with greater frequencies at specific frequencies called resonant frequencies. At resonance frequencies, small periodic driving forces have capacity to produce large amplitude oscillation.
∴ In given scenarios, the case which accurately describes a condition in which resonance can occur is-
C. A pipe's length is equal to 1⁄2 of the wavelength of the sound waves produced by a tuning fork vibrating over one end of the pipe that's open to the air at both ends.
