Answer:
A triad is composed of a T-tubule and two adjacent terminal cisternae of the sarcoplasmic reticulum.
Explanation:
The distribution of related animals and plants across the world shows that those organisms have common ancestor.
There is a term in biology- the most recent common ancestor (MRCA) and it is the most recent individual from which all the organisms are directly descended. It is hard for scientist to identify the exact MRCA, but it is estimated the time at which the MRCA lived (3.5 to 3.8 billion years ago). It is called Last Universal Common Ancestor (LUCA).
Danish scientist Hans Christian Gram devised a method to differentiate two types of bacteria based on the structural differences in their cell walls. In his test, bacteria that retain the crystal violet dye do so because of a thick layer of peptidoglycan and are called Gram-positive bacteria. In contrast, Gram-negative bacteria do not retain the violet dye and are colored red or pink. Compared with Gram-positive bacteria, Gram-negative bacteria are more resistant against antibodies because of their impenetrable cell wall. These bacteria have a wide variety of applications ranging from medical treatment to industrial use and Swiss cheese production.
Vision is to the occipital lobe as touch is to the parietal lobe.
<span>The occipital lobe is the visual processing center and one of the four major lobes of the cerebral cortex in the brain of mammals. This lobe processes the rapid information that our eyes are sending.</span>
The parieatl lobe is other lobe from the foru major lobes. It is positioned above the occipital lobe and behind the frontal lobe and central sulcus. This lobe is responsible for integration of sensory information , including spatial sense and navigation.
