Q: What is the term for the cell fragments involved in blood clotting, which stick to tears in blood vessels and to each other? Read this paragraph and choose the correct option from the provided answers: Platelets are cell fragments involved in blood clotting. They stick to tears in blood vessels and to each other, forming a plug at the site of injury. They also release chemicals that are needed for clotting to occur. Choices: - molecules - droplets - cells - platelets A:
platelets

Q: What is another term for the parabolic motion of a thrown object? Read this paragraph and choose the correct option from the provided answers: In this chapter, we aim to understand and explain the parabolic motion of a thrown object, known as projectile motion. Motion in one direction is unrelated to motion in other perpendicular directions. Once the object has been thrown, the only acceleration is in the (up/down) direction. The (right/left) direction velocity remains unchanged. Choices: - newtonian motion - regular motion - simple motion - projectile motion A:
projectile motion

Q: Q: What is the unique larval form of mollusks called? Read this paragraph and choose the correct option from the provided answers: Mollusks reproduce sexually. Most species have separate male and female sexes. Gametes are released into the mantle cavity. Fertilization may be internal or external, depending on the species. Fertilized eggs develop into larvae. There may be one or more larval stages. Each one is different from the adult stage. Mollusks have a unique larval form called a trochophore . It is a tiny organism with cilia for swimming. Choices: - scallop - hydra - microfilariae - trochophore A:
A: trochophore

Question: Q: What layer of soil usually does not have very small particles like clay? Read this paragraph and choose the correct option from the provided answers: Topsoil usually does not have very small particles like clay. Clay-sized particles are carried to lower layers as water seeps down into the ground. Many minerals dissolve in the fresh water that moves through the topsoil. These minerals are carried down to the lower layers of soil. Choices: - undersoil - sediment - silt - topsoil A:
Answer: topsoil

Q: Reproduction that doesn't involve a male gamete is also known as what? Read this paragraph and choose the correct option from the provided answers: Agamogenesis is any form of reproduction that does not involve a male gamete. These include are parthenogenesis and apomixis. Parthenogenesis is a form of asexual reproduction where growth and development of embryos occur without fertilization. Parthenogenesis occurs naturally in aphids, rotifers, nematodes and some other invertebrates, as well as in many plants and certain lizards, such as the Komodo dragon. Apomixis is asexual reproduction, without fertilization, in plants. Choices: - meiosis - mitosis - asexual reproduction - agamogenesis A:
**Answer**
agamogenesis

Q: What do many cells depend on glucose for? Read this paragraph and choose the correct option from the provided answers: A gated channel protein is a transport protein that opens a "gate," allowing a molecule to pass through the membrane. Gated channels have a binding site that is specific for a given molecule or ion. A stimulus causes the "gate" to open or shut. The stimulus may be chemical or electrical signals, temperature, or mechanical force, depending on the type of gated channel. For example, the sodium gated channels of a nerve cell are stimulated by a chemical signal which causes them to open and allow sodium ions into the cell. Glucose molecules are too big to diffuse through the plasma membrane easily, so they are moved across the membrane through gated channels. In this way glucose diffuses very quickly across a cell membrane, which is important because many cells depend on glucose for energy. Choices: - food - heating - osmosis - energy A:
(Answer)
energy
