I believe this is a bit of a trick question, while you are right about both B and D, they both preexist they just develop into other structures. I believe the correct answer is A since the nerve cord is hollow not solid.

How does the endocrine system control body processes? WORTH 20 POINTS
Sidana [21]

Answer:

The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function.

Explanation:

The endocrine system is responsible for regulating a range of bodily functions through the release of hormones.

Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function.

Some examples of bodily functions that are controlled by the endocrine system include:

metabolism

growth and development

sexual function and reproduction

heart rate

blood pressure

appetite

sleeping and waking cycles

body temperature

Endocrine system organs

The endocrine system is made up of a complex network of glands, which are organs that secrete substances.

The glands of the endocrine system are where hormones are produced, stored, and released. Each gland produces one or more hormones, which go on to target specific organs and tissues in the body.

The glands of the endocrine system include:

The table below shows the amount of carbohydrates in same-size servings of different fruits. Amount of Carbohydrates in Fruit 23
marta [7]

Answer:

As per the data provided, the correct answer would be cherries.

The effect of any food in increasing the blood sugar level can be understood with the help of glycemic load. It takes in the account of both the glycemic index as well as serving size.

It states that the glycemic response of our body depends on both "the type of carbohydrate and the amount of carbohydrate" consumed in a meal.

For example, glycemic response of small size high GI food is the same as that of large size low GI food.

It can be calculated as follows:

\text{glycemic load} = \frac{\text{glycemic index x net carbohydrate}}{100}

Hence, glycemic load of apple would be = (38 x 17)/100 = 6.4.

Similarly, glycemic load of cherries, oranges, and watermelons would be 4.18, 10, 8.6 respectively.

Hence, cherries are the fruit which has low glycemic load value of 4.18. So, the glycemic response of this fruit would be low. Hence, it will result increase the blood sugar by the least value.
