Answer: A
Explanation:
Both C4 and CAM have certain adaptations - like spatial or temporal differences that allow photosynthesis to occur in plants that live in very hot, dry environments where woter loss would be bad.
The Cambrian explosion. Trilobites were found because of their hard shell, unlike soft bodied creatures.
Hypertonic would be the correct answer, there is more solute making the cell let out more water, shrinking the cell, therefore being hypertonic.
Sympathetic Nervous System; Parasympathetic Nervous System
Alma is walking in a park. Suddenly, a wild dog charges toward her. Alma is frightened. The sympathetic nervous system starts to respond by increasing her heart rate and dilating her pupils. After running for a few minutes, Alma realizes that the dog has fallen far behind. At this point, her parasympathetic nervous system starts working to relax her body by slowing down her heart rate and constricting her pupils.
The sympathetic nervous system and the parasympathetic nervous system are components of the autonomic nervous system. The sympathetic nervous system, known as the “fight or flight system” activates the neuronal and hormonal response to stress. It prepares the body to respond to threatening situations by causing effects such as pupil dilation, increased sweating, increased heart rate and blood pressure. The parasympathetic nervous system known as the "rest and digest system” is the opposite of sympathetic nervous system. It inhibits a physiological response and it functions by reducing heart rate, constriction of pupil and relaxation of sphincter muscles in the gastrointestinal tract.
The Sun is a as a G2V type star, a yellow dwarf and a main sequence star. Stars are classified by their spectra (the elements that they absorb) and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M.
