Ques:Q: In a carbon triple bond, how many pairs of electrons are shared? Read this paragraph and choose the correct option from the provided answers: Carbon can form single, double, or even triple bonds with other carbon atoms. In a single bond, two carbon atoms share one pair of electrons. In a double bond, they share two pairs of electrons, and in a triple bond they share three pairs of electrons. Examples of compounds with these types of bonds are represented by the structural formulas in the Figure below . Choices: - one - four - two - three A:

Ans:three

Ques:Q: What kind of energy constitutes the total kinetic energy of all the atoms that make up an object? Read this paragraph and choose the correct option from the provided answers: The atoms that make up matter are in constant motion, so they have kinetic energy. All that motion gives matter thermal energy. Thermal energy is defined as the total kinetic energy of all the atoms that make up an object. It depends on how fast the atoms are moving and how many atoms the object has. Therefore, an object with more mass has greater thermal energy than an object with less mass, even if their individual atoms are moving at the same speed. You can see an example of this in Figure below . Choices: - kinetic energy - phenomena energy - atmospheric energy - thermal energy A:

Ans:thermal energy

Ques:Q: Filter feeders, such as sponges, pump water into their body through what structures? Read this paragraph and choose the correct option from the provided answers: Sponges are filter feeders. They pump water into their body through their pores. The water flows through a large central cavity called the spongocoel (see Figure above ). As the water flows by, specialized collar cells filter out food particles such as bacteria. Collar cells have tiny hairs that trap the particles. They also have a flagellum that whips the water and keeps it moving. Once the food is trapped, the collar cells digest it (see Figure below ). Cells called amebocytes also help digest the food. They distribute the nutrients to the rest of the body as well. Finally, the water flows back out of the body through an opening called the osculum. As water flows through the sponge, oxygen diffuses from the water to the sponge's cells. The cells also expel wastes into the water for removal through the osculum. Choices: - fibers - lungs - valves - pores A:

Ans:
pores
