If the results show that 21% of the nucleotides contain adenine, then the cytosine fraction in vivo is 29% and the thymine fraction is also 21% (options A and C).

<h3>Define double helix model of DNA?</h3>
  1. DNA is a double helix molecule made up of two long strands of nucleotides.
  2. There are four types of nucleotides in DNA, each containing a different nitrogenous base: adenine, guanine, thymine, cytosine.
  3. Adenine always pairs with thymine and guanine pairs with cytosine, according to the base-pairing rules.
  4. As a result, the percentage of adenine equals the percentage of thymine, and the remaining percentage equals guanine + cytosine (29 + 29 = 58 >> 58 + 21 + 21 = 100).
  5. Therefore, if the results show that 21% of the nucleotides contain adenine, then the percentage of cytosine in vivo is 29% and the percentage of thymine is also 21%

Finding variables in the following Students measured the temperature of the water at different depths in Lake Skywalker and foun
Natasha2012 [34]

The independent variable is the one that causes an effect on the dependent variable. In this case, the independent variable is <u>depth.</u> Different depths lead to a variation in temperature. 2)<em> depths</em>.

<h3>What are de dependent and independent variables?</h3>

  • Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results.

This variable is not affected by any other one but influences or causes a reaction in other variables.

  • The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one.

Its response might be either directly proportional or inversely proportional to the change in the independent variable.

Now let us answer the question.

The aim of the study was probably to analyze how temperature changed with depth.

So, according to this, depth influenced on the temperatureof water.

  • The independent influencing variable is <u>depth</u>.
  • The <u>dependent affected variable</u> is water temperature.

The correct option is 2. depths.

timurjin [86]

The correct answer is option b, that is, the addition of carbon dioxide to the atmosphere.  

If the concentration of carbon dioxide upsurges in the atmosphere due to the enhanced rate of outgassing, there will be a constant elevation in the global temperature. The elevating temperature and more dissolved carbon dioxide will result in enhanced weathering of crystal rocks as a consequence of faster rate of reactions and greater acidity.

If all of the offspring have roan coats—white hairs mixed into a base coat of red—what can be said about the red and white allel
madam [21]

Answer:

The alleles for red and white coat color are co-dominant.

Explanation:

Co-dominance is the condition when none of the allele of a gene is dominant. The heterozygous genotype exhibits traits of both alleles.

In the given example, the offspring have roan coat color in which white hairs are mixed into a base coat of red. Since both the alleles are expressed in heterozygous offspring, the alleles for red and white coat colors are co-dominant over each other.
