Explanation

Acetyl Co-A is the first carbon compound that enters the Krebs cycle, combining with oxaloacetate to form citrate.

It is produced from pyruvate during the link reaction before entering the cycle.

Explanation

Given numbers: 20, 26, 40, 36, 23

Step 1: Add them

20 + 26 + 40 + 36 + 23 = 145

Step 2: Divide by the number of values (5)

145 ÷ 5 = 29

Explanation

The common phrase is: "Hard work is the key to success," meaning it is the main factor in achieving success.

"Key" symbolizes access or unlocking success through effort.

Explanation

During gastrulation, the upper layer formed is called the epiblast. 

During the early stages of embryonic development, a process called gastrulation transforms a bilaminar disk (consisting of the epiblast and hypoblast) into a trilaminar disk.

The epiblast is the upper layer, while the hypoblast is the lower layer.

The epiblast eventually develops into the ectoderm.
