Answer:
X linked dominant disorders are caused when the genes on the X chromosomes gets mutated. X linked dominant disorders phenotype is observed in each generation and males experience more severe symptoms of disorder as compared to a female.
In X linked recessive disorder one copy of affected X gene is sufficient to cause the disease in males. In case of females both the X gene are required to be effected for causing disease.
Explanation:
X linked dominant disorders are caused when the genes on the X chromosomes gets mutated. X linked dominant disorders phenotype is observed in each generation and males experience more severe symptoms of disorder as compared to a female. This disorder is never transmitted to male child by the father or in other way we can say that there is no male to male transmission. For example Fragile X syndrome
In X linked recessive disorder one copy of affected X gene is sufficient to cause the disease in males. In case of females both the X gene are required to be effected for causing disease. Males are more affected by this disorder as compared to females. For example - hemophilia
. This disorder is never transmitted to male child by the father just like the X linked dominant disorder or in other way we can say that there is no male to male transmission.
<h3>Answer</h3>
29.2°
<h3>Explanation</h3>
Given in the question,
radius of circle = 4 m
area of sector = 5π m²
The area of a sector of a circle is
<h3>½ r² ∅</h3>
<em>where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle.</em>
<em />
<h3>area of a sector = ½ r² ∅</h3>
5π = ½ r² ∅
5π * 2 = r² ∅
10π = r² ∅
10π = 4² ∅
10π = 16∅
∅ = 16 / 10π
∅ = 8/5π in radians
<h3>Converting rad to degree</h3>
π = 180°
1rad = 180/π
8/5π rad = 8/5π * 180/π
= 8/5π × 180/π
= 29.2°

Answer:
Sunlight is an electromagnetic wave carrying energy that is absorbed by the skin.
Explanation:
Pure H2O is absolutely necessary for all living cells. Almost all water that you are likely to consume, even what we consider to be "fresh water," contains ions (salts); however, many of these ions are also crucial for life (K+, Na+, Cl-, Ca2++ and N3- are some examples) and are non-toxic in the levels present in tap water, streams, lakes, etc. At high concentrations, like the concentration of sodium, chlorides and others found at sea, many of these ions and their compounds are toxic and can result in illness and even death.
<span>In response to high serum (blood) levels of various ions your body will simply try to pee them out. Drinking large volumes of seawater results in dehydration because the body uses more H2O trying to flush the salt out of your blood stream than it is able to retain. Drinking a small amount of salt water most likely will not hurt you, especially if you are already hydrated.</span>
The right option is a. Croup
Croup is an acute respiratory
infection in children and infants characterized by a barking cough and stridor.
The infection causes difficulty in breathing and a hoarse voice. Croup is
caused by parainfluenza virus and other causes include allergies and reflux. The
symptoms of croup are usually worse at night and it can last for about three to
five days.
