Once a standard curve has been prepared by plotting numbers of bacteria (CFU/mL) versus absorbance for one species of bacteria,

this curve can be used for estimating bacterial numbers by measuring absorbance for any species of bacteria.

Answer:

b. False

Explanation:

The biomechanism of bacterial growth may be examined, by graphing cell growth (also known as absorbance) vs incubation time of the bacteria. A standard growth curve is the result of this process. The amount of turbidity in the broth culture is proportional to the number of microorganisms present.

A standard curve produced for a particular species can't be utilized to predict the number of bacterial counts for a different species due to the listed factors.

  • The rate of bacterial cell reproduction varies from a particular species to another.
  • Varying species have different absorbance thresholds.

As mass increases, what is the effect on the star’s temperature?
Masja [62]

Answer: As the mass of star increases, the temperature and luminosity also increases.

Explanation:

This can be described in what happens in main sequence star( example, the Sun), which is powered by fusion of hydrogen into helium in its core. Main sequence star exhibit a common characteristic which is hydrostatic equilibrium. This means,the inward force of gravity, which tends to compress the star, is balanced by the outward force due to the pressure. Thus when an extra mass such as hydrogen is added to its core, there will be increase in mass which leads to a higher compression. This in turn will lead to central density and temperature. As the temperature increases, fusion of gases occurs faster resulting to a much higher luminosity. I hope this helps, thanks.

Which of the following is an example of an allele? *<br><br> 1.H<br> 2. HH<br> 3. Hr<br> 4. RRR
VMariaS [17]

Examples of allele types are HH. That is option 2.

<h3>Gene Allele </h3>

An allele in genetic studies is an alternative gene form that is located at a particular point of the chromosome. It is usually represented with capital and small letter of the same alphabet.

There are two types of a allele which include:

  • Dominant allele: This is when the variation seen in a gene produces a noticeable phenotype. This is seen in the gene combination of HH.

  • Recessive allele: This type of allele does not produce any visible noticeable phenotype. This is seen in hh.

Therefore, examples of allele types are HH
