Is this a science problem
Answer:
D
Explanation:
it is not c since the heart is one organ
and it is not b since there is more than just muscle in the heart so more than one kind of cell
and for a i assume you meant industrial cell which is a machine part
d is the answer heart an organ has 2 or more kinds of tissue that preforms a particular function
Answer:
Graph A: Directional Selection
Graph B: Stabilizing Selection
Graph C: Disruptive Selection
Explanation:
Natural selection as a driving force of evolution cam be defined as a process that a population of organisms undergo in other to become adapted to an environment and survive to produce offspring that are fitter.
Thus, the following graphs represents the three types of natural selection:
Graph A: Directional Selection
Directional selection occurs when one extreme trait is favoured over others by selective pressures.
The graph shows that only one extreme trait is favoured as the population that survives seem to have majorly a particular extreme trait.
Graph B: Stabilizing Selection
In this type of natural selection, neither of the extreme traits are favoured by selective pressures. Therefore, intermediate trait become favoured over the other extreme traits.
Graph C: Disruptive Selection
Selective pressures works against the intermediate trait while both extreme trait at the spectrum are well favoured, which become more established in a population against the intermediate trait.
There are huge flood water marks around the world, which scientists believe took thousands/millions of years to form from a flood. So scientists think the world has been around for millions of years, and came up with the Big Bang Theory after most research did not result in normal science today.
