The breakdown of food via enzymatic reactions is known as __________.
r-ruslan [8.4K]
I believe you're looking for "chemical digestion".

Chemical digestions is where food that we ate is digested into simpler and soluble molecules that can be absorbed by our body. Enzymes are used as a catalyst to speed up the reaction.

One example is the digestion of lipids. Enzyme named lipase is used to speed up the digestion of lipids into 3 fatty acid molecules and 1 glycerol. This way, our body can absorb these simple molecules, and use them in order to make our body function.

On the other hand, physical digestion does not include enzymes, such as chewing in our mouth, therefore, don't mix them up!

Answer: All the given precaution are important to take care when working with heat and fire.

Explanation:

Double check on these precaution should kept be while working or experimenting with fire and heat:

  • Hair should be tied back : bun or pony will be fine. if hair are untied then chances of catching fire by hair will be high.
  • Do not touch hot equipment ,if required use gloves or tongs. Touching hot equipment with bare hands may lead to burns or minor (or major) accident
  • Keep your face and eyes away from the flame while experimenting.Cover your face with mask and goggles.
  • Do not mix chemical until or unless told to do so. This is because some times mixing of chemicals leads to evolution of large amount of heat which can difficult to handle.
  • Be careful regarding cloths while working with heat and fire.
  • Flammables must be kept away and should be used with caution. Safer distance must be maintained

Lena [83]

Answer:

No, observed and expected frequencies are different.

Observed frequencies: p2 = 0.56 , 2pq = 0.375, q2 = 0.062

Expected frequencies: p2 = 0.774 , 2pq = 0.211, q2 = 0.014

Explanation:

Given frequency of recessive genotype (q2)= 14/ 1006 = 0.0139

Frequency of recessive allele s (q) = square root of 0.0139 = 0.12

Frequency of dominant allele S (p) = 1-q = 1-0.12 = 0.88

Expected frequency of homozygous recessive genotype = 0.12 x 0.12 = 0.014

Expected frequency of homozygous dominant genotype = 0.88 x 0.88 = 0.774

Expected frequency of heterozygous dominant genotype = 2pq = 2 x 0.88 x 0.12 = 0.211

Observed frequencies in population 2

Observed frequency of homozygous dominant genotype = 308 / 549 =0.56

Observed frequency of heterozygous dominant genotype = 206 / 549 =0.375

Observed frequency of homozygous recessive genotype = 34 / 549 =0.062

Observed frequencies do not match with expected frequencies.
