Answer: the structure of an atom: At the center of the atom, there is a very small region called the nucleus. This area makes up most of the mass of the atom.
The area around the nucleus is called the electron cloud. This area makes up the majority of the volume of the atom. The electron cloud is mostly empty space.

Two important natural processes that release carbon into our atmosphere are photosynthesis and respiration.
Sternal angle marks the joint between the sternum and the 2nd rib.
Option E.
<h3><u>Explanation:</u></h3>
Sternum is the breast bone which is a dorsi ventrally flattened bone present in thorax of human. It gives the support for the ribs where the ribs join. A sternum has three parts - Manubrium sterni, body of sternum and the xyphoid process.
The sternum has attachments of a total of 10 ribs and clavicle. The clavicle and the first rib joins in the Manubrium sterni, and the 3rd to 10th rib joins in the body of sternum. The 2nd rib joins in a facet which is partly in Manubrium sterni and partly in body of sternum. This place id also called the sternal angle. So the sternal angle marks the joint of 2nd rib to sternum.
<span>The process must occur before the gametophyte generation is Sporophyte. A sporophyte is the diploid generation of a plant or alga that has a double set of chromosomes. [ All land plants, and some algae, have life cycles in which a multicellular haploid gametophyte generation alternates with a multicellular diploid generation. In the Gymnosperms and flowering plants (Angiosperms), the sporophyte generation is the most prominent phase, comprising the familiar green plant with its roots, stem, leaves and cones or flowers. In the flowering plants, the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.</span>
