I would say it's A because the others don't make sense and if they were curved they wouldn't get as much sun
Answer:
This happens because of our immune system. Our immune system keep record of every attacking microbe. It contains two type of while blood cells firstly is T cell that respond quickly to the attacking microbe. While secondly B cells that recognize those specific cells and fights them off. In addition to that B cells clones itself as memory cells for that disease and will remains in your body for years
Answer:
The binding of carbon monoxide (CO) with hemoglobin leads to an R state even in conditions that should produce the release of oxygen. In consequence, CO-hemoglobin binding shifts the oxygen dissociation curve to the left.
Explanation:
Hemoglobin is a globular protein containing four heme groups that can bind to one oxygen each. This protein (hemoglobin) has two conformational states: the T-state, also known as deoxyhemoglobin (a tense state, where lacks O species), and the R-state, also known as oxyhemoglobin (a relaxed, fully oxygenated state). When carbon monoxide binds to hemoglobin, the protein can not release oxygen, shifting the oxygen dissociation curve -which expresses the percentage of oxygen saturation against the partial pressure of oxygen- to the left. Therefore, under CO-hemoglobin binding, the oxygen level in the tissues is reduced.
Answer:
Ocean salt primarily come from rocks on land
Explanation:
some areas of the ocean are more saltier than others.The rain that falls on land contains some dissolved carbon dioxide.
Hope this helped
