The correct answer is (C) in through the pores and out through the osculum
The list which represents the
components of the human skeleton is; Bones, tendons, ligaments, cartilage.
<h3>Skeleton</h3>
The human skeleton is defined as the internal framework of the human body. It is made up of 206 bones at adulthood stage and the bone mass in the skeleton makes up about 14%
The skeleton is divided into 2 parts:
- The axial skeleton: The axial skeleton is the central unit, consisting of the skull, vertebrae, ribs.
- The appendicular skeleton: It comprise the bones of the extremities

Either NaI or INa are acceptable formulae for sodium iodide, which is indeed a binary ionic compound. So, the correct answer would be B.
Answer:
The structure is shown below.
Explanation:
To draw a structure first we need to know its molecular formula, which is C2H6SO for dimethyl sulfoxide. The central atom is sulfur, which is bonded to an oxygen and with two methyl groups (CH3).
Sulfur has 6 electrons in its valence shell, as so oxygen. To complete the octet of oxygen, 2 electrons will be shared by sulfur with it. So, it remains 4 electrons at the central atom. Carbon has 4 electrons in its valence shell, so it needs more 4 to be stable, and is already sharing 3 electrons with the hydrogens, thus, sulfur will share one electron with each one of them.
So, it will remain 2 nonbonding electrons in the central atom. According to the VSPER theory, to minimize formal charges, the structure would be a trigonal pyramid, but, the double bonding with oxygen has a large volume, then the geometry will be trigonal, as shown below.
