Answer:

Earth's surface didn't look much different. With few exceptions.

The global climate is cooler and drier, and seasonal, similar to modern climates. As the climate began to cool down grasslands continued to expand and forests started to dwindle in extent. In the seas, kelp forests made their first appearance and soon became one of Earth's most productive ecosystems. Water from the Atlantic Ocean poured in through the Strait of Gibraltar to deluge the Mediterranean Basin. The event is called the Zanclean flood. Parts of of southern Norway and southern Sweden that had been near sea level rose to form the Hardangervidda plateau and the South Swedish highlands.

Shorty after, the glaciations, uplift of the Rocky mountains and Panama seaway closure began to reshape the Earth.

A particular type of cell doubles in number every hour. Write the function that can be used to find the number of cells present

Orlov [11]

The function to represent the number of cells present at the end of h hours if there are initially 4 of these cells is n= 4(2)ˣ

Given,

A particular type of cell doubles in number every hour.

So, to determine which function can be used to find the number of cells present at the end of h hours if there are initially 4 of these cells.

The number of cells denoted with n.

Therefore, the number of bacteria after every hour will form a geometric series.

<h3>What is Geometric Progression?</h3>

Geometric Progression or geometric Sum of G.P. is refer to as if each term is a multiple of the next term then this sequence.

aₙ =arˣ

Where a is the first term which is 4.

And r is the common ratio r = 2.

Therefore,

The number of cells present at the end of h hours if there are initially 4 of these cells is,

n = arˣ

n = 4(2)ˣ

Hence, the function represents the number of cells present at the end of h hours if there are initially 4 of these cells is n = 4(2)ˣ.

<h3>What is cellular respiration?</h3>

Cellular respiration refers to a series of chemical reactions by which foods can be aerobically converted into energy (ATP) by using oxygen.

Cellular respiration can be divided into Glicolisys, the Krebs cycle and oxidative phosphorylation.

Cellular respiration involves oxide reduction reactions that involve the transfer of electrons (e-) between two or more substances.
