Q: Most sedimentary rocks form from what? Read this paragraph and choose the correct option from the provided answers: Most sedimentary rocks form from sediments. The sediments must be packed together to form a rock. Sedimentary rocks also form as minerals precipitate from saline water. Sedimentary rock formation is described in the next concept. Choices: - volcanic activity - glaciers - erosion - sediments A:
sediments

Q: What is the term for learning from past experiences and reasoning? Read this paragraph and choose the correct option from the provided answers: Insight learning is learning from past experiences and reasoning. It generally involves coming up with new ways to solve problems. Insight learning generally happens quickly. An animal has a sudden flash of insight. Insight learning requires relatively great intelligence. Human beings use insight learning more than any other species. They have used it to invent the wheel to land astronauts on the moon. Choices: - logical learning - consequence learning - experimental learning - insight learning A:
insight learning

Q: Q: Most bacteria may be placed into one of three groups based on their response to gaseous? Read this paragraph and choose the correct option from the provided answers: Most bacteria may be placed into one of three groups based on their response to gaseous oxygen. What are these three groups?. Choices: - potassium - nitrogen - carbon - oxygen A:
A: oxygen

Question: Q: Mendelian inheritance has its physical basis in the behavior of what? Read this paragraph and choose the correct option from the provided answers: 15.1 Mendelian inheritance has its physical basis in the behavior of chromosomes. Choices: - ribosomes - prokaryotes - animals - chromosomes A:
Answer: chromosomes

Q: What helps amplify the effects of extracellular signals? Read this paragraph and choose the correct option from the provided answers: The effects of extracellular signals can also be amplified by enzymatic cascades. At the initiation of the signal, a single ligand binds to a single receptor. However, activation of a receptor-linked enzyme can activate many copies of a component of the signaling cascade, which amplifies the signal. Choices: - electrical cascades - spontaneous cascades - mutation cascades - enzymatic cascades A:
**Answer**
enzymatic cascades

Q: Which rule is a result of trends in energies and is useful in explaining why atoms form the ions that they do? Read this paragraph and choose the correct option from the provided answers: valence shell is called the octet rule. When atoms form compounds, the octet rule is not always satisfied for all atoms at all times, but it is a very good rule of thumb for understanding the kinds of bonding arrangements that atoms can make. It is not impossible to violate the octet rule. Consider sodium: in its elemental form, it has one valence electron and is stable. It is rather reactive, however, and does not require a lot of energy to remove that electron to make the Na+ ion. We could remove another electron by adding even more energy to the ion, to make the Na2+ ion. However, that requires much more energy than is normally available in chemical reactions, so sodium stops at a 1+ charge after losing a single electron. It turns out that the Na+ ion has a complete octet in its new valence shell, the n = 2 shell, which satisfies the octet rule. The octet rule is a result of trends in energies and is useful in explaining why atoms form the ions that they do. Now consider an Na atom in the presence of a Cl atom. The two atoms have these Lewis electron dot diagrams and electron configurations:. Choices: - electrons rule - nutron rule - coupling rule - octet rule A:
(A).
