Explanation:
Pesticides, fertilizers and other toxic farm chemicals can poison fresh water, marine ecosystems, air and soil. They also can remain in the environment for generations. Many pesticides are suspected of disrupting the hormonal systems of people and wildlife. Fertilizer run-off impacts waterways and coral reefs.
The most abundant compound that can be found in the sea apart from water is the sodium chloride (NaCl). This is why we are able to retrieve table salt, which also comes in the same formula, from the sea. When sodium chloride dissociates into its ions, the two ions would be Na+ and Cl- which are called sodium ion and chloride.
An igneous rock can be formed from cooled magma. The igneous rock can become sedimentary if it is broken down by wind or water. The sedimentary rock can become metamorphic if it becomes buried in the earth, where pressure and heat would turn it into a metamorphic rock. The metamorphic rock can then become an igneous rock by melting underground and turning into magma, flowing out of a volcano, and cooling.
A) The crust and outer part of the mantle make up the lithosphere
Answer:
No, telomerase is not an oncogene. It prevents the senescence that would occur due to shortened telomeres, but the cell proliferation might still be mitogen-dependent.
Explanation
telomerase is not responsible for causing deregulation while oncogenes cause deregulation .
Telomeres length shorten after the cell division which stops them to divide again and cell die.
Telomerase prevents this decline in some kinds of cells, including stem cells, by lengthening telomeres, and the hope was that activating the enzyme could prevent senescence.
