Answer:
B. generation of rich organic fertilizer.
Explanation:
Compost and fertilizers are different. There is a simple way to distinguish between compost and fertilizers. Compost feeds the soil, and fertilizer feeds the plants. Fertilizer adds to the soil for nutrient supplying purpose to the plants. But compost helps to increase the microbial activities of the soil, which improves the health of the soil.
Answer:
Sensory transduction.
Explanation:
Sensory transduction may be defined as the process by which sensory stimulus are transformed in the body. The receptor cell is mainly involved in the sensory transduction process.
The sensory receptor cell like a light or an odor is converted into the electrical signal by the process of signal transduction. The information is then conveyed to the nervous system in the form of electrical signals.
Thus, the correct answer is signal transduction.
Answer:
geographical isolation
Explanation:
Reproductive isolation is a process of evolution that ensures that members of different species are incapable of mating and when they do, such mating do not result into any offspring or leads to the production of invalid offspring.
There are two mechanisms of reproductive isolation:
- Pre-zygotic mechanisms prevents fertilization between two different species and these include habitat isolation, mating seasons, mechanical isolation, gamete isolation, geographical isolation and behavioral isolation.
- Post-zygotic isolation prevents the products of fertilization from becoming valid and this include hybrid inviability, hybrid sterility and hybrid breakdown.
<em>Geographical isolation involves the existence of geographical barriers between two populations such that there cannot be mating between the two. The two populations eventually evolve to become different species.</em>
