Answer the following question given this paragraph: Inside the plasma membrane of prokaryotic cells is the cytoplasm. It contains several structures, including ribosomes, a cytoskeleton, and genetic material. Ribosomes are sites where proteins are made. The cytoskeleton helps the cell keeps its shape. The genetic material is usually a single loop of DNA. There may also be small, circular pieces of DNA, called plasmids (see Figure below ). The cytoplasm may contain microcompartments as well. These are tiny structures enclosed by proteins. They contain enzymes and are involved in metabolic processes. Q: What is inside the plasma membrane of a prokaryotic cell? Choices: - protoplasm - electron - alkaline - cytoplasm A:
(Answer)
cytoplasm
Ques: Answer the following question given this paragraph: On the superior aspect of each kidney is the adrenal gland. The adrenal cortex directly influences renal function through the production of the hormone aldosterone to stimulate sodium reabsorption. Q: The adrenal cortex directly influences the function of what organs through the production of the hormone aldosterone to stimulate sodium reabsorption? Choices: - lungs - heart - tumors - kidneys A:
Ans: kidneys
(Q).
Answer the following question given this paragraph: Evolution of Birds The evolutionary history of birds is still somewhat unclear. Due to the fragility of bird bones, they do not fossilize as well as other vertebrates. Birds are diapsids, meaning they have two fenestrations or openings in their skulls. Birds belong to a group of diapsids called the archosaurs, which also includes crocodiles and dinosaurs. It is commonly accepted that birds evolved from dinosaurs. Dinosaurs (including birds) are further subdivided into two groups, the Saurischia ("lizard like") and the Ornithischia ("bird like"). Despite the names of these groups, it was not the bird-like dinosaurs that gave rise to modern birds. Rather, Saurischia diverged into two groups: One included the long-necked herbivorous dinosaurs, such as Apatosaurus. The second group, bipedal predators called theropods, includes birds. This course of evolution is suggested by similarities between theropod. Q: Birds belong to a group of diapsids called the what? Choices: - conifers - mammals - aviators - archosaurs A:
(A).
archosaurs
Ques:Answer the following question given this paragraph: structure in angiosperms consisting of male and female reproductive structures that attracts animal pollinators. Q: Angiosperms possess reproductive structures that attract animals that perform what role? Choices: - evolution - vegetation - isolation - pollination A:

Ans:pollination
Ques:Answer the following question given this paragraph: Metabolic acidosis is problematic, as lower-than-normal amounts of bicarbonate are present in the blood. The pCO2 would be normal at first, but if compensation has occurred, it would decrease as the body reestablishes the proper ratio of bicarbonate and carbonic acid/CO2. Respiratory acidosis is problematic, as excess CO2 is present in the blood. Bicarbonate levels would be normal at first, but if compensation has occurred, they would increase in an attempt to reestablish the proper ratio of bicarbonate and carbonic acid/CO2. Alkalosis is characterized by a higher-than-normal pH. Metabolic alkalosis is problematic, as elevated pH and excess bicarbonate are present. The pCO2 would again be normal at first, but if compensation has occurred, it would increase as the body attempts to reestablish the proper ratios of bicarbonate and carbonic acid/CO 2. Respiratory alkalosis is problematic, as CO2 deficiency is present in the bloodstream. The bicarbonate concentration would be normal at first. When renal compensation occurs, however, the bicarbonate concentration in blood decreases as the kidneys attempt to reestablish the proper ratios of bicarbonate and carbonic acid/CO2 by eliminating more bicarbonate to bring the pH into the physiological range. Q: Why is respiratory acidosis considered to be problematic? Choices: - causes acid stomach - excess oxygen in blood - causes suffocation - excess co2 in blood A:

Ans:
excess co2 in blood
