<u>Answer</u>: B) Cavalier-Smith's model no longer separates prokaryotes and eukaryotes.
Although the Cavalier-Smith's model has introduced several new changes to the kingdom model, it still separates the prokaryotes and eukaryotes into two separate empires (Prokaryota and Eukaryota).
Downstream river would have less water, so there would be less fish to catch.
River re-routing is a process wherein the mouth of the river is mouth to another location. Thus, existing mouth of the river will lose its water source and have less water. Fishes in the existing river path will decrease because of the decreased level of water.

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.
