There are many factors that affect the rate of chemical reactions and temperature is one of them.
Typically, the higher the temperature of a chemical reaction the faster the reaction occur, that is, the temperature and the rate of chemical reaction are directly related. This is due to the fact that increasing the temperature of the reaction increases the kinetic energy of the reacting particles and thus they are able to move faster and the reaction also occur faster. Thus, from the options given, the correct answer will be D [40 degree], this is because, it is the highest temperature out of all the options given.
Answer:
Bioethics is the study of typically controversial ethics brought about by advances in biology and medicine. ... Bioethicists are concerned with the ethical questions that arise in the relationships among life sciences, biotechnology, medicine, politics, law, and philosophy.
Explanation:
Research ethics are important for a number of reasons. They promote the aims of research, such as expanding knowledge. They support the values required for collaborative work, such as mutual respect and fairness. ... They support important social and moral values, such as the principle of doing no harm to others.
Answer:
plicae circulares and intestinal villi
Explanation:
The inner wall of the intestine is full of wrinkles, called villi. An enlargement of them under the microscope reveals that they are formed by cells whose surface has innumerable small "wrinkled" structures. The small intestine is the largest viscera of the body (about six meters). Intestinal villi and microvilli increase the area of contact with the intestine as well as the speed of absorption of food. Blood capillaries and lymph are in these villi to absorb nutrients.
The intestinal villi, have the function of increasing the absorption of nutrients after digestion. They are the folds of the intestines. The surface of the villi has an area of 12 cm² and the microvilli 240 cm².
Villi and microvilli increase the area of intestinal absorption by approximately 30 times and 600 times, respectively, providing exceptionally efficient absorption of nutrients in the lumen.
The entire small intestine has circular folds of mucosa, also called Kerckring valves and circular plicae. Most extend transversely around the small intestine cylinder for about half or two-thirds of its circumference, but some form complete circles, and some have a spiraling direction; The latter usually extend a little more than once around the bowel, but occasionally two or three times. Circular folds slow the passage of partially digested food along the intestines and provide an increased surface for absorption.
The ends of the actin filaments are anchored to the Z-line or disk.
The sarcomere is the primary functional unit of muscle fiber. It is flanked by a Z-band on each end with adjoining I-bands. The Z-band or disk is a dense fibrous structure composed of actin, α-actinin as well as other proteins.
Thin filaments or actin filaments are anchored at one end at the Z-band. Titin is connected to both the Z-band and the M-line. Thick filaments are attached in the middle of the sarcomere at the M-line.
An intermediary filament protein forms a meshwork from one Z-disk to the next across the myofibril. These networks are joined by actin through the protein dystrophin to the sarcolemma.
