Answer:
Energy level
Explanation:
Periods in the periodic table are arranged in rows. Each row indicates a new period. For example, period 1 starts at the top and consist of only two elements, Hydrogen (H) and Helium (He).
The periods indicate the highest energy level of the elements that fall in the same row. So as the period increases, the energy level increases.
1. flask-shaped gland unbranched ducts=SIMPLE ALVEOLAR GLAND
2. slender, straight gland unbranched ducts = SIMPLE TUBULAR GLAND
3. combination of gland shapes = TUBULAR ALVEOLAR
4.branched ducts=COMPOUND GLAND (salivary glands)
All of them are the exocrine glands (their product is secreted on the epithelial surface).
There can be multiple answers to this question so I tried to give you them.
One could be Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter.
The next could also be a Watt, which is the power from a current of 1 Ampere flowing through 1 Volt.
And 1 kilowatt-hour is the energy of one kilowatt power flowing for one hour.
Answer:
e should be the answer and if not, I would consider A. they both seem right
