ANSWER:
Most types of cancer are believed to begin with a random genetic mutation. This is followed by mutations, which endow the cancer cells with properties allowing them to grow without normal controls to become a tumor.
Mutation is any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment.
Genetic Mutations that lead to cancer cell formation can occur in two forms:
1. GROWTH-PROMOTING GENES are commonly mutated in cancer cells, becoming SUPER-ACTIVE and producing cells that are too strongly stimulated by growth receptors.
2. Mutations can INACTIVATE the genes that suppress cell proliferation or those that signal the need for apoptosis. These genes are known as TUMOR SUPPRESSOR GENES.
Cervix
Janine recently had surgery on the neck, or narrow lower portion, of her uterus. Janine's surgery was performed on the cervix.
The cervix is the narrow neck-like passage that forms the lower portion of the uterus in the human female reproductive system. The cervix joins the vagina and uterus and it is mainly made up of fibromuscular tissue. The two major parts of the cervix are ectocervix and endocervix. During menstrual cycle, the cervix opens a bit to allow the passage of menstrual flow. The cervix also dilates largely to allow the passage of baby during childbirth.

Answer:
A scientist who studies water and its properties is a hydrologist.
Explanation:
A hydrologist is a scientist linked to the study of water, both surface and underground, detecting cleanliness or contamination and proposing alternatives for its cleaning and conservation.
A hydrologist's research on the properties of water, its location, distribution and circulation contributes to the maintenance of the environment.
The other options are not correct because:
<em> A) </em><u><em>Entomologist
</em></u><em>: a scientist who studies insects.</em>
<em> B) </em><u><em>Chemist
</em></u><em>: a professional who studies the elements and chemical compounds and their properties.</em>
<em> D) </em><u><em>Oceanographer</em></u><em>
: study both oceans and seas, and their relationship with the environment, the atmosphere and the land.</em>
<em> E) </em><u><em>Toxicologist</em></u><em>: study the effects of toxic or harmful substances on living beings and the environment.</em>
