H.m.'s main problem is that he cannot form new explicit long-term memories. Explicit memory is a type of long-term memory dealing with the recall of facts and experiences. Explicit memory necessitates intentional recall of information. Declarative memory is concerned with the processing of names, dates, places, facts, events, and so on.
These are entities that are assumed to be symbolically encoded and hence may be described with words. Declarative memory, in terms of function, is optimized for rapid processing and learning. Long-term memory that does not require conscious retrieval is known as Explicit memory. Implicit memory is classified into numerous categories, including procedural memory, priming, and conditioning.

facilitated diffusion?
A. Going to jail
B. Being locked out of your house
C. Being escorted into a building
D. Building a LEGO tower
The scenario that is similar to the process of facilitated diffusion is being escorted into a building since it involves an agent making movement easier. The correct option is C.
What is facilitated diffusion?Facilitated diffusion is the movement of molecules of a substance from regions of high concentration to regions of low concentration facilitated by certain transmembrane proteins in cells.
Facilitated diffusion helps move molecules of substances across the selectively permeable cell membrane of cells.
Therefore, in facilitated diffusion, an agent helps to make the movement of molecules faster.

Neurotransmitters can __________________ receptors to turn them on or __________________ them to stop them from transmitting.
Neurotransmitters can excite receptors to turn them on and stop them from transmitting.
To influence another cell across a synaptic gap, a neuron produces a chemical signaling agent known as a neurotransmitter. Any significant organ, target cell, gland, or muscle cell that receives the signal could be another neuron as well. These signals enable you to move your limbs, experience sensations, maintain your heartbeat, as well as receive and process all the information your body receives from other internal body components and your environment. From one neuron (nerve cell) to the following target cell, neurotransmitters transfer chemical signals, or "messages."
The majority of estimates suggest that the neurotransmitter transient lasts only a few hundred to several hundred of microseconds, indicating that post-synaptic activation is marked by a significant degree of non-equilibrium.

Depending on its shape, epithelium is categorized as follows:
squamous, cuboidal, and columnar.The epithelium is categorized according to the number of cell layers and shape:
Simple epitheliumStratified (or compound) epitheliumPseudostratified epitheliumExplanation:
-Epithelium is categorized according to its shape as follows:
Flat and scale-like squamous epithelial cells are characteristics of the squamous epithelium. They can be found in the oesophagus, the mouth's smooth inner lining, and the lungs' alveoli.
Cuboidal epithelium: Cells in this type of epithelium resemble cubes and have identical height and width. Normally, they develop gland and secretory organ ducts.
Columnar epithelium: Due to their greater height than width, columnar epithelial cells resemble columns. Columnar epithelia can be further broken down into ciliated columnar epithelium, which lines the surface of the airway, and glandular columnar epithelium (forming glands).
-The epithelium is categorized according to the number and structure of cell layers:
A single layer of cells comprises the simple epithelium. The thinness of the epithelial barrier generally enables it to carry out tasks like absorption and filtration. Examples include cells in the bronchi, alveoli, renal tubules, uterus, body cavities, stomach, and small intestine.
A stratified epithelium, also known as a complex epithelium, has many cell layers. The multilayered nature of the stratified epithelia allows it to withstand mechanical or chemical harm. Even when certain cells are damaged and come away from the surface of the stratified epithelium, the underlying tissues are still protected from the outside environment
