Coronavirus is a virus. Viruses cannot be caused by bacteria.
Even though is humans can see more color, bees have a broader range of color vision. They can see ULTRAVIOLET LIGHT which gives them an advantage for seeking nectar. (Hope this helps)
Out of the following given choices;
A) excitatory, but not inhibitory, synapses
B) inhibitory, but not excitatory, synapses
C) electrical synapses
D) ligand-gated ion channels
The answer is D. These are transmembrane ion-channel proteins that open to allow ions such as Na, K, Ca, and/or Cl to pass through the membrane in response to the binding of a chemical messenger (i.e. a ligand), such as a neurotransmitter.

Explanation:
Transportation in plants is an interesting process. It includes the transport of all the nutrients and water to all parts of the plant for its survival. In case of plants, the biggest concern is the transport of water and it terminates at the limiting factor depending on its growth. To overcome this problem, a tree uses several processes like Translocation, Storing, Absorption and Utilization of water
Definition of Transportation in plants
Transportation is the process of transporting water, minerals and food to all parts of the plant body.
Transport in plants occurs at three levels:
The uptake and release of water and solute by individual cells.
Short distance transport of substances from one cell to another.
Long distance transport of sap within xylem and phloem.Direction of transport is an important aspect in plants. In case of rooted plants, transport in xylem of both minerals and water is unidirectional from roots to stems. In this, mineral and organic nutrients undergo multidirectional transport. It includes the organic compounds that are formed during photosynthesis are exported to all parts of the plants along with storage organs. Plant growth regulators, hormones and chemical stimuli are also transported in unidirectional or polarized manner, in very small amounts, from where they are formed to other parts

Answer: In multicellular organisms, including humans, all cells, tissues, organs, and organ systems of the body work together to maintain the life and health of the organism. To make sure your body can work correctly, even when it does many things at once, your body must be carefully organized. The smallest unit of our organization, our smallest part, is the cell. (which makes up muscles) can shorten to make your body move.
