Answer:
Cephalocaudal
Explanation:
The cephalocaudal principle is known as the general process of physical and motoric development which take place from infancy into toddlerhood and at times at early childhood of which development obeys a head-to-toe progression.
Cephalocaudal is a word that connotes head to toe. Therefore, the cephalocaudal principle is stated as the overall process of development observed in the first set of years in postnatal development majorly with the period from infancy into toddlerhood.
The cephalocaudal principle has to do with both physical and functional development. On the basis of the earliest (i.e., physical development), physical growth in size, weight, and feature differentiation obey this process or form of development. The signs of this is well observed in a contrast of the physical characteristics of an infant In contrast to a toddler. In consideration of the latter, the head is mostly disproportionately big in contrast to the other parts of the body. By the time the preschool years is over for most children, it is well noticed that most must have done away with this top heavy appearance just as seen in our question.

B. An atom whose nucleus is unstable and emits particles and and energy. This is a Radioactive isotope.
The atomic nuclei of constituent atoms of the same element include the same number of protons but different numbers of neutrons. Radio isotopes are an element's radioactive isotopes. They can alternatively be described as atoms with an excess of energy in their nucleus or atoms with an unstable ratio of neutrons to protons. A radioisotope's unstable nucleus can form either spontaneously or as a result of a deliberate alteration of the atom. Radioisotope production can occur using either a cyclotron or a nuclear reactor. Molybdenum-99, which has a high neutron content, can be produced most effectively in nuclear reactors, whereas fluorine-18, which has a high proton content, can be produced most effectively in cyclotrons. Uranium is the most well-known illustration of a radioisotope that is found naturally. Uranium-238 constitutes all naturally occurring uranium with the exception of 0.7%.

Answer:
C. Acquired herniations of the muscular colon wall mucosa and submucosa
Explanation:
Hernia refers to the development of outgrowth or protrusion of all or part of the organs through their cavity walls or membrane. Diverticulosis is herniation of mucosa and submucosa of the wall of the colon. Diverticulosis is one of the conditions caused by the imbalance of homeostasis. Many sac-like outgrowths develop in the wall of the colon. The outgrowths are in the form of pouches and are called diverticula.
The out-pouching occurs where the muscularis layer of the wall of the colon has weakened. The people with diverticulosis may have no symptoms and no complications. However, when diverticulosis causes inflammation, the person experiences several complications such as pain, vomiting, nausea, etc.
