Astigmatism is not an eye disease or health problem. While it can cause blurred vision, eye strain, and headaches, particularly after prolonged reading, it does not cause […]
What 3 parts are in a nucleotide?
What 3 parts are in a nucleotide? Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine. Which of the […]

What would happen if there was no hydrosphere on earth?
What would happen if there was no hydrosphere on earth? We know weather happens in the atmosphere, but without the hydrosphere, there would be no water to evaporate and so no cloud or rain could form. Without oceans and land (hydrosphere and geosphere), there would be no wind (as winds are produced by differences of […]

Which two branching connect the trachea to the lungs?
Which two branching connect the trachea to the lungs? At its bottom end, the trachea divides into left and right air tubes called bronchi (BRAHN-kye), which connect to the lungs. Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called bronchioles (BRAHN-kee-olz). Which two branching tubes connect the trachea to the […]
