A trisomy is a chromosomal condition characterized by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.
Trisomy means the presence of an extra chromosome in some or all of the body's cells. This results in a total of three copies of that chromosome instead of the normal two copies. For example, Down syndrome (trisomy 21) is caused by having three copies of chromosome 21 instead of the usual two copies.
This genetic condition is the result of a genetic mutation where your cells don't divide as they should. You can't prevent this abnormality from happening during cell division.

Answer:
Hypothesis If the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
Explanation:
Answer:
(a) number of strands (n) = time (t) ÷ proportionality constant (k)
(b) The time needed for the bacterial to double its initial size is 3.36 hours.
Explanation:
(a) Let the rate (time) be represented by t and the amount (number) of strands of bacteria be represented by n
t is proportional to n, therefore, t = kn (k is the proportionality constant)
Since t = kn, then, n = t/k
(b) Initial amount of strands = 300
Amount of strands after 2 hours = 300 + (300 × 20/100) = 300 + 60 = 360
k = t/n = 2/360 = 0.0056 hour/strand
Double of the initial size is 600 (300×2 = 600)
Time (t) needed for the bacterial to double its initial size = kn = 0.0056×600 = 3.36 hours
Answer: Inclusions or inclusion structures serve as temporary storage of molecules like glycogen and melanin.
Inclusion structures are the aggregates formed of specific molecule types.
The inclusion bodies serve the purpose of temporary storage for molecules such as proteins, lipids, glycogen and melanin. One of the major differences between cell organelle and cell inclusion is that organelles are the living components or subcomponents which have particular functions but cell inclusions are non-living compounds or by products of metabolism process present in the cytoplasm.
The germinal layers that give rise to the digestive system is Ectoderm, Endoderm, Mesoderm, Respectively.
