input with options: Answer the following question given this paragraph: A fully developed placenta, like the one in Figure below , is made up of a large mass of blood vessels from both mother and fetus. The maternal and fetal vessels are close together but separated by tiny spaces. This allows the mother's and fetus's blood to exchange substances across their capillary walls without the blood actually mixing. Q: A fully developed placenta is made up of a large mass of what? A:
OPTIONS:
- brain tissues
- plant cells
- estrogen hormones
- blood vessels
output: blood vessels

Q: Answer the following question given this paragraph: Natural Methods of Asexual Reproduction Natural methods of asexual reproduction include strategies that plants have developed to self-propagate. Many plantslike ginger, onion, gladioli, and dahliacontinue to grow from buds that are present on the surface of the stem. In some plants, such as the sweet potato, adventitious roots or runners can give rise to new plants Figure 32.25. In Bryophyllum and kalanchoe, the leaves have small buds on their margins. When these are detached from the plant, they grow into independent plants; or, they may start growing into independent plants if the leaf touches the soil. Some plants can be propagated through cuttings alone. Q: Natural methods of asexual reproduction, such as cuttings or budding, include strategies that plants have developed to perform what? A:

OPTIONS:
- multi-propagation
- mono-propagation
- iso-propagation
- self-propagation

A: self-propagation

input: OPTIONS:
- radiation
- replication
- natural selection
- mutation Now, answer this question: Answer the following question given this paragraph: Mutations are essential for evolution to occur because they increase genetic variation and the potential for individuals to differ. The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer. Q: What phenomenon is essential in order for evolution to occur because it increases genetic variation and the potential for individuals to differ? A:
A:
output: mutation

Answer the following question given this paragraph: Decomposers are heterotrophs that break down the wastes of other organisms or the remains of dead organisms. When they do, they release simple inorganic molecules back into the environment. Producers can then use the inorganic molecules to make new organic compounds. For this reason, decomposers are essential to every ecosystem. Imagine what would happen if there were no decomposers. Organic wastes and dead organisms would pile up everywhere, and their nutrients would no longer be recycled. Q: Without what food chain component, organic wastes and dead organisms would pile up everywhere, and their nutrients would no longer be recycled? A:

OPTIONS:
- acids
- probiotics
- nitrates
- decomposers

Answer: decomposers

Problem: OPTIONS:
- heart
- brain
- Vessals
- blood
Q: Answer the following question given this paragraph: 40.2 Components of the Blood Specific components of the blood include red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum. Blood is important for regulation of the body's pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood clotting. Red blood cells are specialized cells that contain hemoglobin and circulate through the body delivering oxygen to cells. White blood cells are involved in the immune response to identify and target invading bacteria, viruses, and other foreign organisms; they also recycle waste components, such as old red blood cells. Platelets and blood clotting factors cause the change of the soluble protein fibrinogen to the insoluble protein fibrin at a wound site forming a plug. Plasma consists of 90 percent water along with various substances, such as coagulation factors and antibodies. The serum is the plasma component of the blood without the coagulation factors. Q: Red blood cells, white blood cells, platelets, and plasma are all components of what fluid? A:
Answer: blood

Answer the following question given this paragraph: Q: Traits inherited in mendelian patterns are either? A:

OPTIONS:

- divergent or dominant
- recessive or allelic
- dominant or recessive

Answer:
dominant or recessive
