Acid-fast bacteria or acid-fast bacilli can be defined as the group of bacteria that have the ability to resist their decolonization by the acids which are used during the staining process.
An infection that is caused due to an acid-fast organism indicates that the individual is suffering from Tuberculosis or other myobacterial diseases.
An acid-fast bacteria has many protective and invasive techniques which makes the infection difficult to treat, and thus, long-term course of antibiotics is needed for the treatment of such infections.

<span>The two factors that determine the shape of a protein </span><span><span>
1. </span> Primary structure. The sequence of amino acids. Amino acids are the building blocks of protein. It is a strong of linearity that can be thousands in length. Moreover, the formation of the amino acid and its system is influenced by its genes’ nucleotides arrangement. </span>
<span><span>2. </span>Hence the next factor is how is the structure of the amino acids bended and folded with itself that forms the certain protein molecule and forms the larger complex structure</span><span> </span>
Answer:
Interrupt the long winter nights with a brief period of light.
Explanation:
Long day plants, also called short night plants, flower when the dark period is equal or less than the critical period specific for the species. These plants normally flower in summers when nights are short and days are longer. Winters have a long dark period and do not support flowering in shirt night plants.
A continuous dark period is critical for flowering. A short night plant can flower in winters (having longer dark periods) if the dark period is interrupted by exposing the plant with a flash of light. To make short night plants, such as iris to flower in winters, the plant should be given short period of light after completion of critical dark period.
In the Nitrogen cycle there are basically four steps and bacteria is involved in three steps of the N-cycle namely – Nitrogen fixation, Ammonification and De-Nitrification.
The Decomposers bacteria are involved in the ammonification process, where they convert organic waste, rich in nitrogen into simpler compounds usually ammonia which is further broken down into nitrite and nitrate. This process usually occurs in the absence of light and oxygen by anaerobic/facultative bacterias.
<h3><u>Answer;</u></h3>
Coelom
Animals with 3 issue layers may be characterized by the presence or absence of a <u>Coelom</u>.
<h3><u>Explanation</u>;</h3>
- Animals may be characterized by the presence of a coelom, formation of the mouth, and type of cell cleavage during embryonic development.
- Diploblasts contain two germ layers that is the inner endoderm and outer ectoderm, while triploblasts contain three germ layers, that is; endoderm, mesoderm, and ectoderm.
- <em><u>Triploblasts can be further categorized into those without a coelom called acoelomates, those with a true coelom called eucoelomates, and those with “false” coeloms known as pseudocoelomates.</u></em>
