How would you write this number in scientific notation? (Use the carrot key to denote an exponent. ex: 6.02 x 10^23)

NeTakaya

Answer:

$D=5.89\times 10^{12}\ km$

Explanation:

The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.

A number can be written as $x.0\times 10^y$ in scientific notation where x is a real no and y is any integer.

There are 10 zeros in the given number and also there are 12 digits after. It would mean that,

$D=5.89\times 10^{12}\ km$

So, the distance in scientific notation is : $D=5.89\times 10^{12}\ km$

Secondary metabolites are toxic chemicals in plants that are not used in or derived from photosynthesis or respiration. What are

Anuta_ua [19.1K]

Explanation:

Metabolites are the different kinds of the substances which are essential to metabolism of the organism.

Metabolites produced by the plants can be categorized into the primary metabolites and the secondary metabolites.

The primary metabolites have important role in survival of plant and play an active role in the respiration and the photosynthesis.

On the other hand, the secondary metabolites are not involved in normal growth and the development of plant. Although absence of these type of metabolites can lead to impairment of survivability of plant in long run.

Secondary metabolites are produced mostly by the plants for the defense purposes. They include steroids, alkaloids, phenolics, essential oils, resins, tannins, lignins, flavonoids, etc.

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
