Answer:
As mammals grow, they stop producing lactase.
Explanation:
Mammals consume their mother's milk during the first stage of life. Milk has a sugar called lactose. Lactose is a disaccharide formed by the union of one molecule of glucose and another of galactose. To absorb it our digestive system releases an enzyme (lactase) that breaks the union between galactose and glucose. As mammals grow, they stop producing this enzyme, which makes lactose indigestible. As a result, ingesting milk may cause diarrhea, gas and bloating.
Probably over-fishing so the organisms dont have enough food to eat.
Answer:
Both the lithosphere and asthenosphere are part of Earth and are made of similar material. Lithosphere is made up of Earth's outermost layer, the crust, and the uppermost portion of the mantle. In comparison, the asthenosphere is the upper portion of Earth's mantle (which is also the middle layer of Earth).

Answer:
The given blank can be filled with reproduce.
Explanation:
According to Darwin's theory of evolution by Natural selection more individuals are generated in each generation, which can thrive. A phenotypic variation prevails between the individuals and the variation is heritable. When reproductive isolation takes place novel species will generate, and the individuals with heritable traits that better suits the surroundings will thrive. Thus, natural selection is a theory based on the tendency of a species to thrive and reproduce.
Answer:
<u><em> oxygen in the solution will naturally diffuse into the cell.</em></u>
Explanation:
Cells require oxygen for cellular respiration to occur. When a cell is places in a solution having oxygen dissolved in it, The concentration of the oxygen outside the cell will be more as compared to the concentration of oxygen inside the cell. As a result, the cell will take up oxygen by the process of diffusion. Diffusion is the movement of particles from a higher concentration to a lower concentration along a concentration gradient.
