Explanation:

During the process of photosynthesis carbon dioxide is consumed and oxygen is released in presence of sunlight.

    when plant is placed in the yellow solution and kept in sunlight the plant undergo photosynthesis.As a result the yellow solution in the tube in presence of sunlight turns blue because oxygen is released by reduction which is responsible for the blue coloration of the solution.

Which of the following best explains the relationship between temperature and this enzyme?
DochEvi [55]
<h3>Answer:</h3>

Enzymes functions in a specific temperature range.

<h3>Explanation:</h3>
  • Enzymes are biochemical catalysts whose function is to speed up the rate at which chemical reactions occur.
  • Enzymes work best at a specific range of temperatures known as optimum temperature.
  • Low temperatures below optimum levels deactivate the enzyme and thus lowering the rate of enzyme activity.
  • Extreme temperatures, on the other hand, denatures the enzyme altering enzyme's active sites making it difficult for substrates to fit.

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 <em>p </em>to call the frequency of the dominant <em>T</em> allele, and <em>q</em> the frequency of the recessive <em>t</em> 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
