The correct option is: A. Species A possessed larger jaw muscles than species B.
Significant jaw muscles are linked to a more primitive diet. It is thought that the reduction of jaw muscles is part of the evolutionary process. This is a way to create room for a larger brain.
Answer: The hormones secretin and cholecystokinin act on the pancreas, stomach, and gallbladder.
Explanation:
The duodenum produces two more hormones. Cholecystokinin (CCK), similar to enterogastrone, is released when fat is present in the chyme. CCK promotes the contraction of the gallbladder, which releases bile into the duodenum to help emulsify and digest fat more effectively. The other hormone from the duodenum is secretin. In response to the acidic chyme entering the duodenum, secretin triggers the pancreas to release bicarbonate, thereby neutralizing some of the acid.
Response:
B. The meanings of the prefixes chemo- and photo- point to the source of electrons.
Explanation:
The term chemo refers to chemical/drug, whereas photo relates to light. This can be demonstrated through the following examples:
Chemotherapy = treatment using chemicals
Phototherapy = treatment utilizing light
The solute potential is indicated by the formula P = -iCRT, with i representing the ionization constant, C being the molar concentration, R as the pressure constant (R = 0.0831 liter * bars/mole * K), and T signifying the temperature in Kelvin (273 + °C). A 0.15 M NaCl solution at standard atmospheric pressure and 25°C has an osmotic potential of -7.4 bars, with Na+ and Cl- yielding 2 ions (in contrast to sucrose, which counts as one). Therefore, i = 2, and osmosis will drive water from the 0.1 to the 0.15 concentration.
Biotite mica differs from muscovite mica in their chemical makeup. The magma from which muscovite mica develops is generally more felsic and has a lower density in comparison to that of biotite mica.
