Answer:
The correct option is C) Application of toxic fertilizers to crops
Explanation:
Toxic fertilizers are one the main causes which result in water pollution. Due to certain conditions such as flooding, the toxic fertilizers gets drained away into nearby lakes and seas. These toxic fertilizers pollute the water and kill many of the aquatic species living in the lakes or rivers. As a result, the polluted water affects human health when such a water is used for irrigation and consumption needs by the humans.
Volume of a cylinder formula:
V= h(pi×r^2)
If the diameter is 10in, then the radius is 5in
Substitute given values into the formula:
V=20(3.14×5^2)
V=20(78.5)
V=1570in
Answer: In females, most of gametogenesis occurs during embryonic development. Primordial germ cells migrate into the ovaries at week 4 of development and differentiate into oogonia (46,2N).

Explanation:
members of the same species battle each other to protect their young
Their bodies taper to points at both the snout and the tail, reducing water resistance. Also decreasing drag -- and therefore noise -- are dermal denticles, sharp scales that cover the skin of most shark species. Rather than bone, sharks have cartilage, which is much lighter and more flexible. In addition, their livers produce squalene, a fatty oil that helps them remain afloat. Their pectoral fins allow them to quickly change direction, dive and swim upward.
