 Both tested the idea of spontaneous generation.
il63 [147K]3 years ago

The correct answer is:

Both were attempts to disprove spontaneous generation.

Explanation:

The idea of spontaneous generation, an ancient theory that states that living organisms can arise from inorganic objects. Other well-known examples of spontaneous generation were that dust builds fleas, maggots arise from decaying meat, and bread or wheat left in a hidden corner produces mice.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN
Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

  • <em>In any one species, the amount of adenine closely approximates that of thymine.  </em>
  • <em>In any one species, the amount of guanine closely approximates that of cytosine.  </em>
  • <em>The amounts of A, T, G, and C in DNA varies from species to species. </em>

<em>(options A, B and D)</em>

Explanation:

Organizing the data has to:

<u>Source of DNA      A            T            G            C </u>

Streptococcus    29.8       31.6        20.5       18.0

Yeast                   31.3        32.9       18.7         17.1

Herring                27.8       27.5       22.2       22.6

Human                30.9       29.4       19.9        19.8

E. Coli                  24.7       23.6        26.0      25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

Johann gregor mendel's work in genetics focused on traits that exhibit discontinuous variation. what kind of traits are these?
kvasek [131]
Discontinuous variation is when a trait is seen in a population in two or more different forms and there is no continuation along a gradient. A good example that Mendel studied is flower color. The flowers  were either white or purple. There was no in between color. This is caused by an allele for purple or a lack of an allele for purple, which produces no pigment, or  white.

What is most noticeable structural difference between rna and dna?
fredd [130]
Structurally, DNA and RNA are nearly identical. However, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of deoxyribose sugar like DNA.
