Answer:
Explanation:
Based on what is known about the fetal skeleton and the ossification process it can be said that this occurs due to babies having more of the osteoblasts bone cells. These cell's main function is to lay down new bone material, this therefore creates a thicker harder bone which allows for proper support so that the body can continue growing and become stronger overall.
Answer:
The mass number (symbol A, from the German word Atomgewicht [atomic weight]),[1] also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It is approximately equal to the atomic (also known as isotopic) mass of the atom expressed in atomic mass units. Since protons and neutrons are both baryons, the mass number A is identical with the baryon number B as of the nucleus as of the whole atom or ion. The mass number is different for each different isotope of a chemical element. Hence, the difference between the mass number and the atomic number Z gives the number of neutrons (N) in a given nucleus: N = A − Z.[2]
The mass number is written either after the element name or as a superscript to the left of an element's symbol. For example, the most common isotope of carbon is carbon-12, or 12
C
, which has 6 protons and 6 neutrons. The full isotope symbol would also have the atomic number (Z) as a subscript to the left of the element symbol directly below the mass number: 12
6C

Answer: Option C
Explanation:
The basilar membrane can be defined as membrane which is stiff in nature and is found in the cochlea of the inner ear that separates two fluid filled tubes which runs along the coil of the cochlea, scala tympani and scala media.
The movement of the basilar membrane causes the movement of the streocilia as it is attached to the basilar membrane.
The tectorial membrane along with the hair cells move with the streocilia bending with the relative motion of the tectoria membrane. This helps in signal transmission.
This movement causes opening and closing of the gated channels present on the cilia of the hair cells.
