Gradualism and punctuated equilibrium are evolutionary theories. Gradualism suggests a slow, constant pace of evolution, whereas punctuated equilibrium involves rapid speciation events after periods of stability.
The theory of gradualism posits that evolution proceeds gradually, with slow and continuous changes taking place over long periods of time. Species progressively mutate and adapt, leading to gradual phenotypic and genetic changes, eventually resulting in some new species over millions of years.
On the other hand, punctuated equilibrium proposes that species experience long periods of stability (equilibrium), punctuated by short, rapid events of speciation. These dramatic events involve a small segment of the population evolving quickly while the rest of the population remains unchanged, leading to a new species.
In summary, gradualism presents a slow, steady pace of evolution, while punctuated equilibrium supports the theory of sudden evolutionary jumps interspersed with periods of little to no evolutionary change.

Answer:
1) group
2) period
3) numbers of valence electrons
4) increases
Explanation:
When we move in a periodic table from top to bottom or vice versa along a vertical column , it is said that we are moving along a "group" in a periodic table.
Like wise when we move in a periodic table from left to right or right to left in a horizontal row , it is said that we are moving along a "period" in a periodic table.
The classification of elements belonging to any specific group of periodic table is dependent on the total number of valence electron. All elements of with in a group have same number of valence electrons however, the orbitals may change.
The atomic number increases while moving from left to right as the number of orbitals in which the valence electron is found also increase in the same direction.
A vertical column of elements in the periodic table is called a group
A horizontal row of elements in the periodic table is called a period
Atoms of elements in the same group have the same numbers of valence electrons
As you move from left to right on the periodic table, the atomic number increases
1) group
2) period
3) numbers of valence electrons
4) increases
Answer:
Endocrine system may be defined as the system that controls the homeostsis of the organism by the production of hormones in the form of chemical messenger. Endocrine glands secrete their product directly into the blood stream.
The endocrine system regultes the proper growth and body metabolism. These system regulates the sugar level, calcium level and level of other ions in the body. The endocrine system is also responsible for the functioning of gonads.
