Answer:
Cancer is formed when there are mutations in a number of genes.
Explanation:
Malignant tumors are gene diseases which do not mean that cancer is necessarily an inherited disease (only in 5-10% of cases the cancer is inherited) because the vast majority of other tumors are the result of somatic, ie secondary, mutations that lead to malignant transformation.
Only 2% of human diseases are monogenic (caused by a change in one gene). The remaining 98% of the disease is either polygenic (caused by a change in several genes at the same time) or epigenetic (caused by non-genetic or post-genetic disorders of cellular molecules).
The making of replicas of the original fossils, is pretty much the say way, just different materials, in which the fossils originally have been formed and preserved.
When an organism dies, be it a plant or an animal, it gets fossilized only if very quickly after the death it is covered with sediments or mud. The sediments or the mud protect the plant or animal from the outside influences, so once it is kind of in a vacuum, or protective layer if you will, in which parts of the plant or animal that are long-lasting are preserved.
The clay and plaster used for the replica, work in the same way, because they wrap around the fossil tightly and isolate it from outside influences, with the result being different though, as they just make a copy of the fossil.
Answer:
D. A hormonal signaling pathway between endocrine glands and tissues
Explanation:
Our body is formed by a complex organization of various tissue, organs and organ-systems. It has specific mechanisms to regulate the functions of all its cell, tissue and organs. Besides neural system, the endocrine system also plays a crucial role in the regulation of body functions. This system consists of many pathways that originate from the hormone secreting glands called endocrine glands and reaches to the target cell or tissue or organ. These pathways are collectively named as the endocrine axis.
