best place to find information about the hazards that are associated with a
compound are areas that is related to power plants. Since these areas utilize
chemicals that if not handled properly maybe harmful to others (e.g radioactive
chemicals may cause mutation).</span>

Answer: D. at most 10
Explanation:
Using the energy pyramid, the ratio of grassland to primary consumer to secondary consumer is: 100:10:1 respectively.
Thus if the grassland supports 100 cattle (primary consumer), the numbers of humans (secondary consumer) the cattle can feed will be;
100/10 = 10.
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.
