Weak acids and bases are indicators. All indicators are weak acids. An acid-base conjugate pair has different colors. Any indicator changes color when the pH of its solution is 7.
Answer:
Muscle Tissue : The kidneys rely on blood pressure to move, since they lack muscle tissue.
Epithelial Tissue : The kidneys contain simple cuboidal epithelial tissue, which secretes and absorbs. Thus absorbing toxins from blood to be turned to urine.
Nervous Tissue : Kidneys to not contain nervous tissue due to the fact that they do not control when you urinate, but rather simply just pass the urine to the bladder.
Connective Tissue : Kidneys do contain Connective Tissue, called renal fascia, in order to keep the many elastic tubes in place, and a capsule of renal fascia closely envelopes each kidney to protect, and provide support for each kidney inside.
Answer:
The asthenosphere in plate tectonic theory. The asthenosphere is now thought to play a critical role in the movement of plates across the face of Earth's surface. ... Some observers have described the asthenosphere as the 'lubricating oil' that permits the movement of plates in the lithosphere.
The right answer is A. greater leaf surface area.
In botany and agronomy, the specific leaf area (SFS) is defined as the ratio of the leaf area to the dry weight of the leaf (expressed in m².kg-1).
The specific leaf area reflects the "thickness" of the leaves and has a particular physiological significance. This parameter is correlated positively with the photosynthetic capacity of the plant.
The specific leaf area can be used to estimate the reproductive strategy of a particular plant based on, among other factors, light and moisture levels. The specific leaf area is one of the most widely accepted key features used in the study of leaves.
