hope this not childish.
Changes in the dna are called mutations. They can occur spontaneously. Mutations can only be passed down in gametes--sperm and egg cells. with Darwins theory at mind a mutation needs to pass the test of natural selection to remain in the gene pool. So purposly making mutation or altercations may end in diseases/illnesses or in some cases death because they body can not take it.....hope this helps if it doesnt im sorry!
Answer:
Sternocleidomastoid, pectoralis minor, scalenes
Explanation:
During normal inhalation, contraction of the diaphragm and the contraction of external intercostals expands the chest cavity. The increased volume of the thoracic cavity results in reduced alveolar pressure than the atmospheric pressure to facilitate the flow of air into the lungs in response to the pressure gradient.
During deep inhalation as it occurs when running up the stairs, the accessory muscles of inhalation also participate to increase the volume of the chest cavity. The contraction of scalene and sternocleidomastoid muscles increase the volume of the chest cavity further to create a greater drop in alveolar pressure.
During forceful inhalation, the sternocleidomastoid muscles serve to elevate the sternum, the scalene muscles serve to elevate the first two ribs while the pectoralis minor elevate the third through fifth ribs.
Answer: The correct answer is A) Stratum basale.
Sudoriferous glands are also called as 'Sweat glands'. They are exocrine glands as they secrete their substances through the duct. They are tiny tubular glands with the secretory unit which is present in the dermis or subcutaneous tissue, and a duct which opens on the surface of the skin. Their primary role is regulation of body temperature as by sweating, body heat is lost.
During fetal development, sudoriferous glands develop from the Stratum basale. It is the deepest layer of the epidermis. It is made up of a single layer of cells which are resting upon the basement membrane, a layer present between dermis and epidermis.
Thus, sudoriferous glands are derived from Stratum basale during fetal development.
