A minimum change in sensory intensity that is noticeable to an observer and can be coded into neural messages is known as the
AURORKA [14]
Difference threshold is a minimum alteration in sensory intensity that is noticeable to an observer and can be coded into neural messages. Different threshold is the lowest level of encouragement that is essential to sense that a modification has happened the difference in the intensity between two stimuli that is necessary to yield a just notable difference also known as JND. The just notable difference depends not only on the intensity of the new stimulus but also on the level of stimulation already present which is the more intense the existing stimulus the larger the change must be to be noticeable.

Bioflix activity: meiosis -- comparing mitosis and meiosis can you identify the similarities and differences between mitosis and
Natali5045456 [20]
1. Similarities:
they are both processes of cell division by which cells reproduce.
They share several steps of the process(prophase, metaphase, anaphase e telophase, cytokinesis) but meiosis has another division also with those same steps.
In both cases the cell duplicates its DNA by pulling it apart into two sets, place the sets on each end of the cell, and then divide down the middle.

Both produce new cells based on their parent cells' genes.

2. The differences:

Mitosis:

- has 1 division per cycle
- one cell produces 2 new cells
- the genetic information in the mother-cell and the daughter-cells are the same. ( the number of chromosomes is also the same)
- it occurs in somatic cells
Meiosis:
- two divisions per cycle.
- one cell when divides produces 4 new cells
- the new cells have different genetic information. mixes the  the genetic material from the parent cells
- the number of chromosomes of the daughter cells is half of the mother's.
