The correct answer is C. Clavicle and scapula
Explanation:
The pectoral girdle, also called the shoulder girdle refers to a set of bones that connect the arm to the rest of the skeleton. In human beings and many other species, the pectoral girdle consists of the clavicle that is a long bone that goes from the shoulder to the sternum and the scapula that is a flat bone and goes from the upper zone of the arm to the clavicle. Additionally, in some species, the shoulder girdle includes a third bone called coracoid. According to this, the pectoral girdle consists of the clavicle and the scapula.
Fossils can provide the time a species existed through carbon-14 dating, and can also show structures within the species that are similar to other organisms on earth today or other organisms before/slightly after that fossils existence.
Answer:
B) how changes in development underpin the evolution of morphology.
Explanation:
Evolutionary developmental biology is the new field of research in biology which studies the combined relationship of the evolution and the developmental processes.
This interdisciplinary study compares the developmental biology in terms of evolution or in a way that how the developmental biology process evolved in the organism on the basis of studying the phenotypic features of the organisms.
Thus, Option-B is the correct answer.
The atomic number of an atom is the number of protons it has, and if the atom is neutral, it will also be the number of electrons. Therefore:
The atom you're talking about has 103 protons, and an atomic number of 103.

➜ <u>Mendel conducted breeding experiments with garden peas</u>:
[i] He studied plants (pure) of a tall/short varities.
[ii] He crossed them and obtained F1 progeny.
[iii] He found that F1 progeny was all tall plants.
[iv] He selfed the (hybrid) plants if F1 progeny.
[v] He found that in F2 progeny there were tall as well as short plants.
[vi] The three quarter plants were tall and one quarter was short.
(or any other contrasting character may be taken).
<u>Note</u>: Here, F1 means <u>First fillial generation</u> and F2 means <u>Second fillial generation</u>.
