Answer the following question given this paragraph: on a daily basis as a preventive measure. However, aspirin can also lead to serious side effects, including increasing the risk of ulcers. A patient is well advised to consult a physician before beginning any aspirin regimen. A class of drugs collectively known as thrombolytic agents can help speed up the degradation of an abnormal clot. If a thrombolytic agent is administered to a patient within 3 hours following a thrombotic stroke, the patient's prognosis improves significantly. However, some strokes are not caused by thrombi, but by hemorrhage. Thus, the cause must be determined before treatment begins. Tissue plasminogen activator is an enzyme that catalyzes the conversion of plasminogen to plasmin, the primary enzyme that breaks down clots. It is released naturally by endothelial cells but is also used in clinical medicine. New research is progressing using compounds isolated from the venom of some species of snakes, particularly vipers and cobras, which may eventually have therapeutic value as thrombolytic agents. Q: Snake venom may join the class of drugs collectively known as thrombolytic agents, which can help speed up the degradation of an abnormal what? A:
OPTIONS:
- brain
- bleed
- bone
- clot

Answer: clot

Question: Answer the following question given this paragraph: Evolution means change over time. Darwin's theory of evolution says that organisms change over time ( Figure below ). Evolution is seen in the fossil record. It is seen in the way organisms develop. Evolution is evident in the geographic locations where organism are found. It is evident in the genes of living organisms. Evolution has a mechanism called natural selection . The organism that is best suited to its environment is most likely to survive. Evolution is described in the chapter Life on Earth . Q: Organism's changing over time is called? A:
OPTIONS:
- generation
- heterogenicity
- variation
- evolution
Answer: evolution

input with options: Answer the following question given this paragraph: Early in the development of a human fetus, the skeleton is made entirely of cartilage. The relatively soft cartilage gradually turns into hard bone through ossification . This is a process in which mineral deposits replace cartilage. As shown in Figure below , ossification of long bones, which are found in the arms and legs, begins at the center of the bones and continues toward the ends. By birth, several areas of cartilage remain in the skeleton, including the ends of the long bones. This cartilage grows as the long bones grow, so the bones can keep increasing in length during childhood. Q: While still an early fetus, what is the skeleton made of? A:
OPTIONS:
- ligament
- membrane
- gel
- cartilage
output: cartilage

Q: Answer the following question given this paragraph: Hydrozoa includes nearly 3,500 species, most of which are marine. Most species in this class have both polyp and medusa forms in their life cycle. Many hydrozoans form colonies composed of branches of specialized polyps that share a gastrovascular cavity. Colonies may also be free-floating and contain both medusa and polyp individuals in the colony, as in the Portuguese Man O'War (Physalia) or By-the-Wind Sailor (Velella). Other species are solitary polyps or solitary medusae. The characteristic shared by all of these species is that their gonads are derived from epidermal tissue, whereas in all other cnidarians, they are derived from gastrodermal tissue (Figure 15.14ab).

Q: Most hydrozoa have both polyp and what forms in their life cycle? A:

OPTIONS:
- hydra
- globular
- polypoid
- medusa

A: medusa

Question: Answer the following question given this paragraph: A human sperm is a tiny cell with a tail. A human egg is much larger. Both cells are mature haploid gametes that are capable of fertilization. What process is shown in this photograph? Notice the sperm with the head piece containing the genetic material, a flagella tail that propels the sperm, and a midpiece of mostly mitochondria, supplying ATP. Q: What part of the sperm contains the genetic material? A:
OPTIONS:
- the " body "
- the " tail "
- the " brain "
- the "head"
Answer:
the "head"
