study revealed that Food Crops are the major crops cultivated in the study area‚ and the effects of climate change on agricultural production results to soil loss‚ plant nutrient loss‚ textural change‚ increase in pests and diseases and poor yield germination etc. This study therefore recommended that cover trees should be planted‚ which will provide shade and reduce heat‚ due to climate change and the preservation of underground water.

In both cases‚ birth is experienced; however‚ with plants the process is called mitosis and with animals it is called meiosis. In plants gametes are not produced directly

In this paper‚ I will be discussing about a zoonotic disease that caused the first of all infectious death of man and animals by a specific organism. This organism is capable of developing into very resistant spores‚ that soon develop to survive for many years and under any conditions. I will also be discussing the three forms of anthrax‚ the factors influencing the infection‚ common source of infection‚ how humans can contract it‚ where it grows‚ it’s incubation period‚ the signs after the incubation
