Answer:
D.It recycles and reuses organic molecules so they are not wasted.
Explanation:
Most of the fungi are decomposer so they gain their nutrition from dead and decaying matters. They release hydrolytic enzymes that help in the break down of dead organic matters of plants and animals and release the nutrition from them.
So they replenish and recycle the nutrient in the environment. They also protect the environment from pollution by degrading these dead organic matters. Therefore these organic matter are not wasted. Many fungi also live in symbiotic associations with algae and plants and help in their survival.
So the correct answer is D.It recycles and reuses organic molecules so they are not wasted.
The correct option is C.
Scientists believed that the earth tectonic plates are in constant motion, this motion is slow and its rates vary. The motions of the tectonic plates are caused by the convection current which is found in semi molten mantle. The convection current are created by heat within the earth surface. When a semi molten rock is heated, it become less in density compared to its surrounding and thus rises up. When the less dense molten rock reaches the crust above, it spread out and carries the tectonic plate above with it. When the molten magma cools down, it sinks and the whole process is repeated leading to continuous movement of the tectonic plates.
Answer:

Answer:
The correct answer option is C. They are target specific.
Explanation:
We are to determine whether which of the given statements is true about antibody.
Antibodies are a type of proteins which are present in the body to defend the foreign attacks that are in the form of antigens.
These proteins have a basic structure which consists of two pairs of polypeptide chains that are linked covalently via disulfide bonds.
Each antibody recognises one specific antigen and this feature is called as antibody specificity.
