Q: What type of organism is a bacteria? Read this paragraph and choose the correct option from the provided answers: The single-celled prokaryotic organism otherwise known as bacteria. And all it takes is one to quickly grow, under just the right conditions, into millions and billions. Luckily, we know how to control bacteria when necessary. But bacteria do serve many important purposes. In fact, we could not survive without them. Choices: - multicellular organism - fungi - paramecium - single-celled prokaryotic A:
single-celled prokaryotic

Q: Shedding of dead cells ensures constant renewal of what outer layer of the skin? Read this paragraph and choose the correct option from the provided answers: The skin consists of two distinct layers, an outer layer called the epidermis and an inner layer called the dermis. The epidermis is constantly being renewed as dead cells on the surface are shed. This layer contains melanin-producing melanocytes. The dermis contains blood vessels, nerve endings, hair follicles, and sebaceous and sweat glands. Choices: - scale - cuticle - dermis - epidermis A:
epidermis

Q: Q: Innate behaviors occur in all animals. however, they are less common in species with higher levels of what? Read this paragraph and choose the correct option from the provided answers: Innate behaviors occur in all animals. However, they are less common in species with higher levels of intelligence. Humans are the most intelligent species, and they have very few innate behaviors. The only innate behaviors in humans are reflexes. A reflex is a response that always occurs when a certain stimulus is present. For example, a human infant will grasp an object, such as a finger, that is placed in its palm. The infant has no control over this reaction because it is innate. Other than reflexes such as this, human behaviors are learnedor at least influenced by experiencerather than being innate. Choices: - hormones - interdependence - nonverbal communication - intelligence A:
A: intelligence

Question: Q: Why is respiratory acidosis considered to be problematic? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - causes acid stomach - excess oxygen in blood - causes suffocation - excess co2 in blood A:
Answer: excess co2 in blood

Q: What is it called when an egg develops into an individual without being fertilized? Read this paragraph and choose the correct option from the provided answers: Parthenogenesis Parthenogenesis is a form of asexual reproduction in which an egg develops into an individual without being fertilized. The resulting offspring can be either haploid or diploid, depending on the process in the species. Parthenogenesis occurs in invertebrates such as water fleas, rotifers, aphids, stick insects, and ants, wasps, and bees. Ants, bees, and wasps use parthenogenesis to produce haploid males (drones). The diploid females (workers and queens) are the result of a fertilized egg. Some vertebrate animalssuch as certain reptiles, amphibians, and fishalso reproduce through parthenogenesis. Parthenogenesis has been observed in species in which the sexes were separated in terrestrial or marine zoos. Two female Komodo dragons, a hammerhead shark, and a blacktop shark have produced parthenogenic young when the females have been isolated from males. It is possible that the asexual reproduction observed occurred in response to unusual circumstances and would normally not occur. Choices: - symbiosis - abiogenesis - metamorphosis - parthenogenesis A:
**Answer**
parthenogenesis

Q: What term describes the amount of solute in a given amount of solution? Read this paragraph and choose the correct option from the provided answers: The concentration of a solution is the amount of solute in a given amount of solution. A dilute solution has a low concentration of solute. A concentrated solution has a high concentration of solute. Choices: - density - temperature - cloudiness - concentration A:
concentration
