While looking at a cell under a microscope, a scientist is able to see a biological molecule. This molecule is a nucleic acid wi

th double strands and contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on this information, what conclusion can the scientist draw regarding this nucleic acid?

He/she would be able to conclude that due to the lack of uracil and presence of double strands that the molecule is DNA and not RNA.

Answer:

It is a DNA molecule (deoxyribonucleic acid).

Explanation:

There are only two types of nucleic acids in nature based on their structure and composition which are mentioned as under:

(1) DNA (Deoxyribonucleic acid)

(2) RNA (Ribonucleic acid)

A DNA molecule is characterized by double helix in which two strands which are anti parallel to each other are joined together with the help of interactions like hydrogen bonds which exist between the nitrogenous bases of these two strands. For example, adenine of one strand is joined with thymine of another strand by 2 hydrogen bonds (A=T) while cytosine of one strand is joined with guanine of another strand by 3 hydrogen bonds (C≡G). In contrast to this, an RNA molecule is single stranded therefore no such interactions exist in the RNA molecule.

Also, an RNA molecule does not have thiamine as nitrogenous base in it, instead of thiamine it has uracil.

Based on the above mentioned facts we can easily conclude that this nucleic acid is DNA.

Jena is reading about factors that affect Florida's climate. One sentence reads: Most of Florida is less than 100 feet above sea
Marrrta [24]

<u>Answer:</u>

Jena is reading about the elevation.

<u>Explanation:</u>

  • Elevation is the altitude (height) above the sea level. The Florida being at the height of less than 100 feet is its elevation.
  • The major factor that affects the climate of that region is its elevation.as the elevation increases i.e. the height of the place from sea level increases the temperature of that place lowers.
  • For every 1 kilometer rise in elevation the temperature decreases by 6.5 degree Celsius. Hence, Jena is concerned about the elevation.

Which action would best demonstrate that a scientist is being creative?
xxMikexx [17]

Answer:

taking a closer look at the natural world

Explanation:

using prior knowledge is basic common sense. so no.

requiring evidence and thinking logically is following a rule. so no.

following strict rules when using human test subjects. right off the bat, "strict rules" is an immediate no.

taking a closer look at the natural world. that's creative because they look for the answer around them.

In a population of panthers, there are 60 black panthers, 30 pink panthers, and 10 white panthers. PP is produces black, Pp prod
Olin [163]

Answer:

0.25

Explanation:

The population of panthers consists of 60 black panthers with the dominanat allele PP. 30 are pink panthers with the genotype Pp and 10 panthers are white with the phenotype pp.

The frequency of p allele in the population can be determined by

the number of individual with pp genotype + 1/2the number of individual with Pp genotype divided by the total number of individual.

Frequency = 10+1/2*30/100

Frequency = 0.25.

Thus, the frequency of p genotype is 0.25.
