Answer:
B) nuclei of gland cells.
Explanation:
DNA carries the blueprint for the production of all the proteins including enzymes in human beings. Humans are eukaryotes and their DNA is present in the nucleus of their cells. All the cells that make the complex human body are derived from division in the zygote and therefore, are genetically identical and have the same DNA.
However, gene expression is regulated by the expression of specific genes in specific cells and at a different time of developmental stages. Amylase is the enzyme that digests starch in humans. Amylase is secreted by salivary glands. So, the nuclei of these glands would have genetic information for the synthesis of amylase.

Physical Weathering in Nature. When water in a river or stream moves quickly, it can lift up rocks from the bottom of that body of water. When the rocks drop back down they bump into other rocks, and tiny pieces of the rocks can break apart. Many rock surfaces have small crevices on them.
Ex: Unloading.
The sun evaporates the water from ponds, oceans...etc. There the water turns into water vapor, a gas. Then it participates from the cloud and restarts all over again.
Protons- these have a positive charge
Electrons-negative charge
Neutrons- neutral charge
