8 0

Answer:

Both are correct

Explanation:

Not all are flowers in the path of engine progress and development. There is a phenomenon that haunts technicians since the beginning of engine development and, it seems, will always be present in the lives of those who work with the engines, this phenomenon is called abnormal combustion, also known as spark knock, ping, and detonation.

During abnormal combustion the increase in temperature and pressure within the combustion chamber which can cause serious engine damage.

When comparing proteins and polysaccharides, the following similarities
lianna [129]

Answer:

The comparison of proteins and polysaccharides establishes that they have similarity in both consist of linked monomers via the process dehydration reactions.

Explanation:

Both proteins and polysaccharides are polymers whose structure consists of the union of monomers. In the case of proteins the monomer is the amino acid, while in the polysaccharides can be glucose molecules.

The process of polymer formation is called polymerization, and one of the reactions that this process allows is <u>polycondensation</u>, where a water molecule is lost in the union of monomers.

The loss of water in a chemical reaction involves dehydration, a characteristic shared by the processes of adding monomers to proteins and polysaccharides.

The other options are not correct, because

  • <em>Hydrolysis produces the rupture of molecules, with the intervention of water.</em>
  • <em>Only polysaccharides are sugars bound by the dehydration synthesis process.</em>
  • <em>Only proteins consist of amino acids linked through the process of hydrolysis.</em>

A species of fly has two alleles for the length of their legs. The allele for long legs is dominant and is represented by p. The
ankoles [38]
The answer is 0.43


To calculate p we will use one of two formulas of the <span>Hardy-Weinberg principle:
</span>

p² + 2pq + q² = 1 and p + q = 1

where:

p - the frequency of the allele for long legs which is a dominant trait.
q - the frequency of the allele for short legs which is a recessive trait.

p² - the frequency of dominant homozygote (with long legs)

2pq - the frequency of heterozygote (with long legs)

q² - the frequency of recessive homozygote (with short legs)


So, 33 of 100 organisms have short legs. The frequency of recessive homozygote is represented by q²:

q² = 33/100 = 0.33

⇒ q = √0.33 = 0.57


Using the formula:

p + q = 1

p = 1 - q = 1 - 0.57 = 0.43


Therefore, p = 0.43
