Expand your assays beyond cell counting with preconfigured templates for many commonly used cell imaging and analysis protocols such as apoptosis and detection of mitochondria
The mechanism in a cell's connected section of the membrane that detects chemical signals is i.e. structure labelled B in the diagram. Thus, the correct option is D.
<h3>
What are receptors?</h3>
Receptors, which are large proteins that can be found within or outside of cells, are the components of a cell that are in charge of identifying chemical signals.
Whereas plasma membrane junctions interact with surface proteins found inside cells during cell to cell signaling.
Thus, it follows that the structure designated B in the diagram is the one that serves as a chemical signal receptor.

Answer:
Hydrogen.
Explanation:
Hydrogen is the simplest chemical element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.
Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.
Based on the octet rule which states that atoms of chemical elements gain, lose or share electrons so as to have eight (8) electrons in their valence shell. Therefore, atoms of chemical elements bond in order to attain the electronic configuration of a noble gas i.e a full valence shell which comprises of eight (8) electrons.
However, the chemical element "Hydrogen" is an exception to the octet rule because it is only able to hold a maximum of two (2) valence electrons in its outermost shell to become full.
<em>Hence, Hydrogen is an element which does not want to have eight valence electrons. </em>
In the ecosystems of the world, there are many evolutionary finds that scientist have been exploring for centuries. In the marine ecosystem, plankton are a form of microevolution. They also migrate, known as vertical migration. This can affect the ecosystem in that during this migration, the heterotrophs consume various micro-organisms.
