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.

• Skeletal and limb abnormalities
• Central nervous system alterations
• Heart defects
These are applicable in examples to many drugs that reach the developing fetus or embryo can cause death or congenital defects.
<h3>What is meant by congenital defects?</h3>
- A congenital anomaly is a morphological or functional abnormality that appears during intrauterine life.
- These illnesses, which are also known as birth defects, congenital disorders, or congenital abnormalities, arise during pregnancy and can be detected before or at birth as well as later in life.
<h3>What kinds of flaws are instances of congenital?</h3>
- Cleft lip and palate are typically discovered during standard prenatal screenings.
- congenital heart disease, which might include a hole in the heart, a valve issue, or a blood vessel issue.
- Usually identified in the first few years of life, cerebral palsy.
<h3>Each of the medications or drug classes listed below has the potential to give birth to abnormalities in an unborn child:</h3>
- ACE inhibitors (angiotensin converting enzyme).
- antagonist of angiotensin II.
- alcohol

Answer:
a). At least one intron must be present in gene X.
b). At least two intron must be present in gene Y
c). It is impossible to determine whether there are any introns in gene Z.
Explanation:
Introns may be defined as the segments in the RNA molecule or the DNA molecule that does not code for proteins and they interrupts the sequences of each of the molecules.
In the context, we get :
a). In the gene X, at least one of the intron is present. Sometimes more than one introns may also be present. Due to slicing, we get one band less in the cDNA which is made from the mRNA.
b). In dene Y, at least one intron is present. Sometimes more than one introns are present inside the gene Y. In this case we get two bands less in the gene due to slicing.
c). In gene Z, it is not possible to determine the number of introns present in them. In genes X and Y, the Haelll enzyme is present in the intron. Therefore we get less of band after splicing the mRNA to cDNA.
Answer:
trend toward a sporophyte-dominated life cycle
the trend toward larger gametophytes
Explanation:
<em>The major trend in the evolution of land plants is the domination of the sporophytic phase in the life cycle and alternation of generation. It also moves towards a larger gametophytes</em>
In lower plants, the gameophyte phase was dominant in the life cycle while in bryophyte, both gametophyte and sporophyte phase are co-dependent.
The sporophyte phase is the diploid phase while the gametophyte phase is the haploid phase.
Also, the gameotyptic stages are quite microscopic (usually in the form of spores) in lower plants while they become bigger in land plants (in the form of ovary and pollen) although with fewer cells.
Answer:
No specific test exists to diagnose Parkinson's disease. Your doctor trained in nervous system conditions (neurologist) will diagnose Parkinson's disease based on your medical history, a review of your signs and symptoms, and a neurological and physical examination.
