Answer:
Prokaryotes and Eukaryotes
Explanation:
In the primitive atmospheric condition where there was less or no oxygen about 3.8 billion years back, the origin of life started from the appearance of the unicellular prokaryotes, which were characterized by the absence of a well-developed nucleus in their body. They were able to form a single cell within which they comprised the essential requirements for the survival of life.
About 600 million years back, the unicellular organisms gave rise to the formation of multicellular eukaryotes, which were comprised of a well-defined nucleus that was able to form after undergoing episodic evolutionary changes on earth. This is how the evolution of life has taken place from the primitive simple prokaryotic organisms to the modern-day complex multicellular eukaryotic organisms.
Answer:
work in its usual way, but with programmer-defined data types
Explanation:
Operator overloading allows a programmer to define added functionality for an operator. Operator overloading allows expressivity from the user; with operator overloading, programmer will express him/herself easily.
A good reason for overloading an operator is to enable it to work in its usual ways but with programmer-defined data types.
Answer:
ITS B
Explanation:
The direction of velocity is perpendicular to the direction of the position and tangent to the circular orbit. Direction of velocity is constantly changing. When an object moves in a circular orbit, the direction of the velocity changes and the speed may change as well.
The direction of velocity changes at every point in a circular motion. The tangent at any point gives the direction of velocity at that point, where as acceleration is always directed towards the recent in a uniform circular motion.
Answer: B. He should create a budget and start saving for a new car and house.
Explanation: In other to make his goals of buying a car and a house attainable, the first step John should take is to create a budget and start saving towards his goals.

manner that is consistent and a way of having a manner that can be predicted or
is predictable with the use of given factors involving the natural world.
