7. During normal human development a fetus stores a larger amount of fats.During which trimester does the fetus grow the most in size and increase its fat stores? During the first trimester During the second trimester During the third trimester During the fourth trimester

## Step 1<br />The question is asking about the trimester during which a fetus grows the most in size and increases its fat stores. The options provided are the first, second, third, and fourth trimesters.<br /><br />## Step 2<br />The first trimester is primarily focused on the formation of the fetus's organs and systems. This is a critical period for the development of the fetus, but it is not the period where the most growth in size or increase in fat stores occurs.<br /><br />## Step 3<br />The second trimester is characterized by the development of the fetus's features and the beginning of the growth in size. However, the most significant growth in size and increase in fat stores does not happen during this trimester.<br /><br />## Step 4<br />The third trimester is the period where the fetus experiences the most growth in size and increase in fat stores. This is because the fetus is preparing for life outside the womb, and it needs to build up fat stores for insulation and energy.<br /><br />## Step 5<br />The term "fourth trimester" is not a recognized term in human development. It is often used colloquially to refer to the final three months of pregnancy, but it is not a standard term in medical or biological contexts.
