Answer the following question given this paragraph: Populations may show different patterns of growth. The growth pattern depends partly on the conditions under which a population lives. Two common growth patterns are exponential growth and logistic growth. Both are represented in Figure below . Q: What are 2 common growth patterns of population? Choices: - migratory and logistic - exponential and economical - organic and inorganic - exponential and logistic A:
exponential and logistic
Answer the following question given this paragraph: lava flows from a volcano and hardens into rock. Q: Lava flows from a volcano and hardens into what? Choices: - life - snow - sand - rock A:
rock
Q: Answer the following question given this paragraph: Equations in chemistry must balance. There must be the same number of each type of atom in the products as there is in the reactants. Coefficients are used to balance chemical equations. They show how many atoms or molecules of a substance are involved in a reaction. Q: In science, coefficients are used to balance what kind of equations? Choices: - liquid - isolated - mineral - chemical A:
A: chemical

Rodents are gnawing animals that include beavers, mice, and squirrels. Q: What is the name of the group that rats are apart of called? Choices: - primates - Animals - Mammels - rodents A:
Answer: rodents

Answer the following question given this paragraph: The intertidal zone is the narrow strip along the coastline that is covered by water at high tide and exposed to air at low tide (see Figure below ). There are plenty of nutrients and sunlight in the intertidal zone. However, the water is constantly moving in and out, and the temperature keeps changing. These conditions require adaptations in the organisms that live there, such as the barnacles in Figure below . Q: What zone is the narrow strip along the coastline that is covered by water at high tide and exposed to air at low tide? Choices: - aquifer zone - disturbance zone - astrolabe zone - intertidal zone A:
**Answer**
intertidal zone

Answer the following question given this paragraph: 15.4 Mollusks and Annelids The phylum Mollusca is a large, mainly marine group of invertebrates. Mollusks show a variety of morphologies. Many mollusks secrete a calcareous shell for protection, but in other species, the shell is reduced or absent. Mollusks are protostomes. The dorsal epidermis in mollusks is modified to form the mantle, which encloses the mantle cavity and visceral organs. This cavity is distinct from the coelomic cavity, which the adult animal retains, surrounding the heart. Respiration is facilitated by gills known as ctenidia. A chitinous scraper called the radula is present in most mollusks. Mollusks are mostly dioecious and are divided into seven classes. The phylum Annelida includes worm-like, segmented animals. Segmentation is both external and internal, which is called metamerism. Annelids are protostomes. The presence of chitinous hairs called chaetae is characteristic of most members. These animals have well-developed nervous and digestive systems. Polychaete annelids have parapodia that participate in locomotion and respiration. Suckers are seen in the order Hirudinea. Breeding systems include separate sexes and hermaphroditism. Q: What do many mollusks secrete for their protection? Choices: - mucus - sedimentation shell - microscopic shell - calcareous shell A:
(A).
calcareous shell
