Answer:
The question is not well structured, the correct one is;
Look at the following statement. What word completes the second gap? Substances move by active transport from an area where they are __________ concentrated to an area where they are __________ concentrated
The answer is MORE
Explanation:
Substances move from one position to another in living systems. This movement of substances can either be passive (without energy) or active (require energy). Active transport of substances involves the movement of substances against their concentration gradient.
Ideally, substances move naturally from an area they are more concentrated to an area they are less concentrated but in active transport, the opposite occurs i.e. substances move from area that they are less concentrated to one that they are more concentrated, which is going up against the normal concentration slope/gradient. Due to this, energy in form of ATP is usually required by the cell to perform active transport unlike passive transport that occurs without energy input.
Exanples of active transport in living cells are exocytosis and endocytosis in some organisms. Based on this explanation, the first gap will be LESS while the second gap will be MORE.
Answer:
the moon is one-fourth the size in earth diameter (write fraction in the blank.) the distance from the moon to the earth is 385,000 earth diameters. one of the limitations of this model is that it does not describe the movement of the earth and the moon in each of their orbits. complete the sentences below to add that information to the model it takes 27 days to orbit around the earth. the moon orbits earth in a Circle
Answer:
The lake was the result of an ice dam on the Clark Fork caused by the southern encroachment of a finger of the Cordilleran Ice Sheet into the Idaho Panhandle. It was the largest ice-dammed lake known to have occurred.

Answer:
6.7 to 7.0
Explanation:
In the digestive systems of humans and many other mammals, an alpha-amylase called ptyalin is produced by the salivary glands, whereas pancreatic amylase is secreted by the pancreas into the small intestine. The optimum pH of alpha-amylase is 6.7–7.0.
Answer:
Heat, pressure and chemistry compounds around the rocks.
Explanation:
Metamorphic rock is formed by pre-existent rocks (igneous and sedimentary, sometimes from another metamorphic rock), those rocks were modified by the effect of heat (high temperature), pressure (under the terrestrial surface) and chemistry compounds around the rocks. The physical and mineralogical composition becomes different than the original form.
This process is called metamorphism.
