Answer the following question given this paragraph: Sexual reproduction occurs when spores from two parents fuse and form a zygospore. Q: What forms when the spores from two parents fuse during sexual reproduction? Choices: - xerophyte - spirogyra - monospore - zygospore A:
zygospore
Answer the following question given this paragraph: A liquid that can interact with glass displays the property of adhesion . The attraction of the glass to the molecules is stronger than the attraction of the liquid molecules to each other. The liquid molecules are pulled up due to their stronger attraction to the glass. Water is one liquid that displays this property. Q: What property does liquid display when it interacts with glass? Choices: - property of repulsion - property of diffusion - property of oxidize - property of adhesion A:
property of adhesion
Q: 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? Choices: - brain tissues - plant cells - estrogen hormones - blood vessels A:
A: blood vessels
Question: 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? Choices: - multi-propagation - mono-propagation - iso-propagation - self-propagation A:
Answer: self-propagation

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? Choices: - radiation - replication - natural selection - mutation A:
**Answer**
mutation
Answer the following question given this paragraph: The temperature of a region is the other important part of climate. The rate of chemical reactions increases with higher temperatures. The rate doubles for every 10C increase in temperature. Plants and bacteria grow and multiply faster in warmer areas. Q: What happens to the rate of chemical reactions in higher temperatures? Choices: - they become erratic - they stop - they decrease - they increase A:
they increase
