Answer: The correct answer for the blank is-
unpaired and spinning in the same direction.
The given question relates to the atoms of Ferromagnetic materials, which are the materials that produce magnetic effect. They have potential to form permanent magnets and they possess unpaired electrons, which spin in the same direction.
Example of ferromagnetic material- Iron.
B. Glucose
C. Carbon Dioxide
D. Water
The glucose is the chemical food source for the soybean plants. The correct option is B.
Glucose, also known as dextrose, is a type of carbohydrate known as a simple sugar, this can be found in both plants as well as animals.
The molecular formula for glucose is . It is found in fruits and honey and is the most abundant free sugar in the blood of higher animals.
Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar.
Plants use glucose for energy and to make other substances such as cellulose and starch. Cellulose is used to form the basic cellwalls. Starch is stored as a food source in seeds and other plant parts.
The chemicalsource of food for the soybean plants is glucose as per the given scenario.
Thus, the correct option is B.

Explanation:
True or False?
Answer:
Resting potential is when there are more positively charged ions outside the cell than there are inside the cell, and this is the regular state.
Threshold potential is when there is a triggering event that depolarizes the cell body, where positively charged ions enter the cell body at a rapid rate.
Depolarization is when the membrane potential gets smaller, and the cell begins to equalize itself on the inside and out. Positively charged ions enter the negatively charged axon, resulting in the cell being positively charged.
Repolarization brings the cell back to its resting potential - the ion gates of the cell close, keeping the positively charged ions out, while the potassium gates remain open.
