Answer:

Through the study of meteorites, their chemical composition of silicates—material made of silicon and oxygen. Others contain metal—nickel and iron. Knowing what the meteorite was composed of lets you know where it came from. Chondrites are composed of hardened lava - this is occurred at the beginning of the solar system (4.5 mya). Carbonaceous chondrites contain carbon and water which formed away from the sun.

Tay–Sachs disease is an autosomal recessive disorder. Homozygous recessive individuals lack a key enzyme called hexosaminidase A

myrzilka [38]

Answer:

0.033

Explanation:

Tay–Sachs disease is an autosomal recessive disorder. The possible genotypes and phenotypes are:

TT = normal
Tt = carrier
tt = Tay-Sachs disease

I will use p to call the frequency of the dominant T allele, and q the frequency of the recessive t allele.

If the population is in equilibrium, the frequency of the tt genotype is q².

$q^2 = 1/3600\\\\q=\sqrt{1/3600} \\\\q=1/60=0.017\\\\and\\p + q = 1\\p=1-q\\p=0.983$

The frequency of the Tt genotype is 2pq.

$2pq= 2*0.983*0.017\\2pq=0.033$

The Tay–Sachs carrier frequency will be 0.033

Answer: Mutation

Explanation: Mutation is a change in DNA sequence, it may occur due to error when the DNA is copied or it can arise from various environmental factors such as exposure to chemicals, UV radiation, Highly infectious microbes.

Mutation maybe spontaneous. Acquired mutations occur at some point in a person's life and are present only in certain cells, not in every cell in the body while some may target a tissue, an organ or an entire system.
