Answer:
Water is a covalent compound.
Explanation:
covalent compounds are individual molecules characterized by the sharing of electrons between two or more atoms. Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled.
Example:
Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), Water (H2O) and iodine monobromide (IBr).
Properties:
1. At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas.
2. Covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.
3. Covalent compounds have lower melting and boiling points.
Answer:
The correct answer is C. helps process explicit memories for storage.
Explanation:
The hippocampus is an structure of the brain and is located inside the temporal lobe. The main function of the hippocampus is to mediate the generation and recovery of memories in conjunction with many areas spread across the cortex and with other areas of the limbic system. It helps to process and recover the episodic memory (those related to events) and spatial memory (mode in which we perceive space or dimensions). This organ is also where short-term memories become long-term memories, that is, it acts as a mediator of memories, acting as an activation node that allows different memories distributed across different parts of the brain to be activated.
Answer:
ATP and NADPH are used to energy for the production of the Calvin cycle. Once their energy is released, they revert back to ADP and NADP+ and can be reused again.
Explanation:
ATP and NADPH are energy carriers that can be used to power chemical reactions. Once they have energized cellular processes, they become their 'low energy' form of ADP and NADP+. Later, they can reform ATP and NADPH to power more reactions
The answer is B An observation about the number or amount of something
