Question
The major functions of the plasma membrane NOT A. separation of the fluid environments in and outside the cell B. regulation of molecules and ions that pass into and out of the cell C. recognition and communication between different cells and tissues D. maintaining connections between adjacent cells E. production of proteins used in construction of the cell wall Antidiuretic hormone (ADH): A. is produced by the kidney B. increases the amount of water in urine is produced by the adrenal gland decreases the volume of urine produced both A and B Which best describes the first law of thermodynamics? A Energy is neither created nor destroyed, but it can change into matter Energy is neither created nor destroyed, but it can change from one energy rm to another C. Energy can be created from matter or used to produce matter D. Energy transfers are always 100% efficient in changing energy from one useful form to another The secretes seminal fluid. vas deferens follicle C. prostate gland D. endometrium E. both C and D What do we call the maintenance of internal conditions of an organism within a certain physiologically acceptable range? A. evolution B. metabolism C, adaptation D. homeostasis E. photosynthesis Which is the best definition of diffusion: to an A. movement of molecules from an area of their higher concentration area of their lower concentration lower concentration to an area B. movement molecules from an area of their area of low of their higher concentration membrane from an C. movement of water across a concentration the release water concentration to an area of higher water through D. movement of a substance up its concentration gradient of energy from ATPExplanation / Answer
80. E
All the remaining are the functions of plasmamembrane it is called selectively permeable membrane.
81. D
ADH is a hormone that DECREASES urine production.
ADH causes the kidneys to return more water to the blood; thus decreasing urine volume.
82. B
The First Law of Thermodynamics (Conservation) states that energy is always conserved, it cannot be created or destroyed. In essence, energy can be converted from one form into another.
83. C
Prostate gland secretes a portion of the semen & an alkaline fluid that increases motility & fertility of the spermatozoa.
84. D
It is through homeostatic mechanisms that body temperature is kept within normal range, the osmotic pressure of the blood and its hydrogen ion concentration (pH) is kept within strict limits, nutrients are supplied to cells as needed, and waste products are removed before they accumulate and reach toxic levels of concentration.
85. A
Diffusion is a physical process where molecules of a material move from an area of high concentration (where there are many molecules) to an area of low concentration (where there are fewer molecules).
