Lamarck was strong on the inheritance of acquired characteristics but may have placed too much emphasis on this happening in a short period of time like perhaps a few generations. Charles Darwin showed that something similar happened by natural selection of varieties that were favorable to the survival of the species and the extinction of varieties that were not adapted to the natural conditions, but that this process took time but in the end, an organism can develop more favorable traits like mankind when he/she developed the apposable thumb which was an innovation that allowed him to progress from his ape ancestors.
There are different kinds of angles. The measure of each exterior angle of the formation is 51.4.
<h3>What is a exterior angle in math?</h3>
The term exterior angle is known to be the angle that is found between a side of a polygon and that of an extended adjacent side.
The shape of the halftime is regular heptagon.
Note that a regular heptagon has 7 congruent sides and 7 congruent interior angles.
So the exterior angles are said to be congruent, based on the fact that angles supplementary to congruent angles are regarded as congruent.
So Let take n as the measure of each exterior angle.
7n = 360
n= 360/n
To Solve for n =51.4
Therefore, The measure of each exterior angle of the formation is 51.4.

Multiplication is the process of multiplying. The marked-up percentage is 200%.
<h3>What is multiplication?</h3>
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The markup percentage can be found by multiplying the ratio of the profit earned to the cost price by 100%.
Given that the cost price of the cookies is $4, while the selling price of the cookies is $12. Therefore, the marked-up percentage is,
Markup percentage = ($12-$4)/ $4 × 100%
= 8/4 × 100%
= 2 × 100%
= 200%
Hence, the marked-up percentage is 200%.
