Answer:
Our Moon doesn't have an atmosphere because it is too small and doesn't have a strong magnetic field. Any atmosphere it might have had would be stripped away by the solar wind that barrages the small world. In contrast, our planet has more mass to hold its atmosphere close, and a strong magnetic field to protect it.
Answer:
The behaviorist strategies that show to be least effective in therms of supporting language learning: <u>error-correction</u>.
Explanation:
The behaviorist strategies on language learning and acquisition, involves reinforcement or reward of some kind. This theory explains learning as a process that is based on the stimulus given to the learner to achieve the goal. A person learns through practice and imitation of the given excersises.
The less effective strategie would be error and correction, because a person needs to make mistakes in order to practice and learn. By focusing on the error and the correction, this may not be the most motivatinal strategy for a student.
In short and in general, formal language is the language you would use when talking to your boss or employes and informal language is the one you use when talking to a friends

Answer:
The best answer to fill in the blank in the question: Active transport is the protein-mediated movement of substances _____, would be: Against a concentration gradient.
Explanation:
In cellular activity there are several means by which a cell may either introduce, or expell, molecules, ions, gases, waste, or water to survive. While some of these elements may enter a cell´s intracellular environment, and leave it, relatively easily, some require the help of proteins present in a cell membrane in order to either enter or exit the cell. Ions, especially, given that they are vital to maintain the cell´s capability of reacting to different stimulus, have to be particularly balanced out and controlled. In order to do so, the cells membrane possesses a series of proteins inserted between the layers that work as both gated channels and also as transporters that will allow the ions to move as they are required by the cell. Active transport then is the active passage by these proteins on the cell´s membrane of ions against their concentration gradients.
