Answer;
-Endocytosis
Explanation;
-Endocytosis includes; phagocytosis, pinocytosis, and receptor mediated: Endocytosis brings substances into the cell, plasma membrane surrounds the substances to be taken in, encloses them in a membrane-bound sac (vesicle) and brings them into the cell
-Phagocytosis: endocytosis of large solid particles (“cell eating”)
-Pinocytosis: endocytosis of extracellular fluid that contains dissolved solutes (“cell drinking”)
-Receptor-mediated: highly selective, ligands bind to specific receptor proteins on the plasma membrane and are then taken into the cell
-Exocytosis: the reverse of endocytosis: substances are removed from the cell; vesicles fuse with plasma membrane and release their contents into the extracellular fluid; important in nerve cells to release neurotransmitter and secretory cells to release cell products (ex. digestive enzymes, protein hormones).
Providing long-term control over the body's internal conditions
Keeping conditions within a normal range
Adjusting the "set point" for body temperature based upon level of activity
<u>Answer:</u>
<em>It is advantageous to have lesser number of bones in the pectoral girdle.</em>
<u>Explanation:</u>
Pectoral girdle is made up by the bones that connect the upper limbs to the appendicular skeleton which includes all the limb bones. Pectoral girdle in humans is made up of two bones. They are clavicle (collar bone) and scapula. The pectoral girdle allows the free movement of upper limbs.
The bones of pectoral girdle are not as massive as the bones of pelvic girdle since it doesn’t have the function of support. Lesser number of bones in pectoral girdle makes movement of upper limbs more free.
Explanation:
1) Medical Practice was in confusion- Everyone could exercise lacking constraint or drill
2) Medical measures were original- no practical knowledge
3) Mislaid institutional principal- no extensive growth of hospitals
4) Request was unbalanced- least claim due to self-sufficiency (family folk-remedies), economic circumstances (opportunity cost of transportation), and purchase costs (fee for service)
5) Medical education was substandard-apprenticeship, unhindered access, and lacking in science based exercise
Urbanization increased dependence on particular skills of remunerated professionals because..
a. Separated people from families and neighborhoods’- no more home-based medicines
b. Women started working outdoor- no longer thoughtful for the sick
c. Physicians became less expensive and more reachable- telephones, cars, roads reduced opp. cost of time and travel- more reasonable
d. Better topographical closeness of patients and physicians
