In some jacana species, males take care of the eggs and young, and females compete among themselves for territories that contain

one to several males. Female jacanas are significantly larger than males. Which of these statements would you predict to be true of this bird species?
a. Male jacana fitness is primarily limited by ability to take care of eggs and raise young.
b. Female jacana fitness is limited by the number of males in her territory with which a female mates.
c. Variation in reproductive success should be greater in male jacanas than in females.
d. Variation in reproductive success should be greater in female jacanas than in males.
e. Males and females have equal variation in reproductive success.

How does meiosis introduce genetic variation into offspring?
Pachacha [2.7K]
<span>Genetic variation is introduced as a result of the distinct crossing over of chromosomes in both phases of prophase. In the meiosis process, there can also be mutations in the s phase which are very unpredictable and can result in some very significant variations depending on where the coding is. by independent assoartment and 3 by mutations in s phase. Because of the way that </span>meiosis is set up it allows for the offspring to be either very similar to the parents or can even be very different from these factors.

If the nucleotides 5'-GAT-3' are paired with the nucleotides 3'-CUA-5', the pairing must be __________.
arlik [135]

Answer:

The correct answer is A.) during transcription

Explanation:

The pairing during DNA replication and transcription is a little bit different. During replication, A pairs with T, T with A, C with G, and G with C. In transcription T is replaced by U so when there is nucleotide adenine is present in the DNA sequence than uracil will be added against it as complementary nucleotide in mRNA during transcription.

So here 5'-GAT-3' nucleotide sequence is present in DNA and after transcription the nucleotide sequence will be 5'-CUA-5' because U is added against A during transcription. Therefore the correct answer is A.

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.
