Answer:
Uncontrolled cell division can lead to the formation of masses of cells that can remain in a place called <u>primary </u>tumors or ones that can move called <u>metastatic </u>tumors.
Explanation:
The term primary tumor refers to the original tumor, a place where the tumor first appeared.
Metastatic tumors are tumors that appear in other organs and originate from the primary tumor. Tumor cells can break away from the primary tumor and travel to other locations in the body through the blood or lymph system and form new tumors. This is how metastatic tumors appear.
For example, a brain tumor is a primary tumor if it first appeared in the brain. A metastatic brain tumor is a tumor that appeared in another organ and then spread to the brain.

Answer:
The correct answer is - B. lower environmental availability of CO2
Explanation:
In C4 plants they have developed a mechanism for the CO2 concentrating and leads to the lower environmental availability of CO2 for these plants, C4 to avoid photorespiration.
These plants tend to be found in drier environments with high sunlight levels and not thrive in a cool shady forest due to this mechanism that results in low availability of carbon dioxide.
The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.
The function of the urinary system is to filter blood and thus produce urine as a waste by-product. The body absorbs nutrients from food and converts them into energy. After the body has gained the required food nutrients, certain waste by-products remain in the bowel as well as in the blood.
The urinary system assists the body in eliminating liquid waste called urea with the help of kidneys, and also maintains fluid balance i.e. water and mineral (like sodium, potassium) balance.
Urea is transported to the kidneys via the bloodstream. It is finally removed together with water and certain other wastes in the form of urine.
