Answer:
The best answer to the question: These cellular structures are utilized in strong involuntary muscle contractions and transmission of electrical impulses, would be: T-Tubules.
Explanation:
In both skeletal and cardiac muscle, not smooth muscle, because of the way that the muscle fibers are conformed into tight bundles of sarcomeres (skeletal muscle) and myocardiocytes (cardiac muscle), there is a need for a series of structures that will ensure that when there is a stimulus from the nervous systems, these stimulus will propagate to all the cells in the fibers, and not just one.
Aside from counting with a neuromuscular motor plate, which will receive the neurotransmitter from the nerve endings and produce the appropriate reactions, as well as propagate that reaction to all the cells that are being stimulated, muscle fibers also have a structure known as T-Tubules. T-Tubules are formations much like roadways of cell plasma membrane that connect not just one, but all the cells within a muscle fiber so that once a stimulus comes, all the cells will initiate the process of calcium release and action potential propagation. These T-Tubules will ensure that electrical impulses reach all muscle cells and that all cells react at the same time as needed.
Answer:
Explanation:
Osmosis is the process in which the molecules of a solvent move from a region of low concentration to a region of higher concentration through a semi-permeable barrier.
While eating the chips, <u>the salt content from the chips makes the surrounding solution of the cells to have an increase in salt concentration causing an hypertonic solution</u>. An hypertonic solution is a solution that has more solute (salt) than the (solute in a) cell. <u>This increase in salt concentration around the cells causes the cells to release water to neutralize the high salt concentration in the solution around the cell (in order to maintain homeostasis)</u> which causes dehydration in the individual and hence making the individual to be thirsty. <u>The body attempts to maintain balance by passing this excess salt out of the body in the form of urine hence the reason for the dark colour in the urine </u>(because if the body doesn't rid itself of the high salt concentration, the cells could shrink and die as a result).
Answer:
Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.
In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
Answer:
The cells of the wings contain more mitochondria compared to the insect body
Explanation:
The cells in the wings of an insect have more mitochondria compared to the cells of the insect body. Because the wings require more energy for their movement then rest of the body.The insects primary mode of locomotion are the wings the cells of muscle help to move that's why the wings cells contain more number of mitochondria than the body.
