Answer:
The thyroid gland increase in size.
Explanation:
Iodine plays an important role in the generation of thyroid hormones and is mainly found in the soil in coastal areas and in seawater. In the developing nations, the individuals who live at high elevations or inland are generally deficient in iodine and can develop a condition known as goiters.
In the condition, the thyroid gland increases in size in an attempt to get more iodine. However, in the countries where iodine is added routinely to foods and table salt, the lack of dietary iodine is not the typical reason of goiters.
Answer:
The sensitization and awareness campaign by Teddy's organization was aimed to prevent greenhouse effects by preserving the integrity of the ozone layer in deflecting the dangerous ultraviolet radiation from the sun.
Explanation:
Products such as aerosols, refrigerators, and other substances that can release Chlorofluorocarbons (CFCs) had been banned due to their bye product of CFCs which had been studied to be harmful to the ecosystem, especially the stratosphere.
The released CFCs are volatile and escape faster due to their low relative density. Therefore, they tend to get into the upper atmosphere within a couple of minutes. When CFCs and Ultraviolet radiation reacts, it leads to the formation of mono oxides of chlorine and bromine. These fragments (Cl2O and Br2O) are capable of reducing the protective ozone shield into ordinary oxygen, which cannot prevent the penetration of harmful ultraviolet radiation into the earth, which cause mutation of DNA and destruction of protein content of the animals and plants on the earth, and finally to cancer and other genetic mutation problems.
The correct answer is D. Vacuole
Explanation:
In cells, the vacuole is the organelle in which different substances or solutions are stored, this includes wastes, water, food, and even solids that the cell does not require because they are waste and therefore might contaminate the cell or substances the cell store to be used later. Due to this, the vacuole is a chamber that contains specialized membranes that allow certain substances to go in or out. Also, vacuoles can be found in plants, animals, fungi, among others although in organisms such as plants they are bigger. According to this, it is vacuoles the organelle that stores wastes, water or food.
Vacuoles. It can be found in plants, fungal and some protist cells.
