Answer:
Explanation:
Rainforests are the sources of minerals, fruits and vegetables. This is because of the fact that the region acquires an annual rainfall of 250 and 450 centimeters. This supports the growth of diversity of floral species like sugarcanes, cinnamon, rubber, medicine and pineapples. Due to the availability of appropriate rainfall the region exhibit highly fertile soil which can support the agricultural practices. The region is also suitable for the mining of inorganic minerals as it is not completely inhabited by the human population therefore, the society will remain protected against the mining hazards. It is also ideal for the construction as the land will be occupied with aesthetic beauty of nature.
On the basis of above reasons the humans have impacted the rainforests on large scale. Therefore, the statement, Humans have impacted the rainforests through mining, agriculture, and construction. is true.
Answer:
We get oxygen from the air i.e. atmosphere. Green plants release oxygen in the atmosphere as a byproduct of photosynthesis. Respiratory system is responsible for obtaining oxygen from the environment. Circulatory system on other hand helps in delivering this oxygen to different cells of the body with the help of blood.
We get nutrients from the food that we eat. Digestive system breaks down all the complex compounds (such as polysaccharides, polypeptides, fats etc) into simpler elements which are easy to absorb.
produced as a waste product by the cells is carried by the blood to alveoli in the lungs where it gets diffused out and come out of the body as a part of exhale air. Hence, circulatory system helps in he transportation of from cells to the lungs and respiratory system helps in expelling it out from the lungs to the outside environment.
Solid wastes are mainly excreted out of the body from anus which is a part of digestive system. On the other hand, liquid waste (urine) is excreted out of the body with the help of urethra which is the part of excretory system. In addition, excess salts and water can also excrete out of the body through skin.
Muscles and bones together help us in our locomotion. Nervous system is important for proper functioning of bones and muscles.
Meiosis is the type of cell division used to produce haploid cells or gametes from a diploid parent cell. Hence, it is used in reproduction system to produce sperm in males and eggs in females.
