Which of the following could be a hypothesis for what causes a scarlet ibis to have red feathers?A. the red feathers make the bird more beautiful to people
B. A chemical in the birds food produces the red coloring
C. What does the scarlet ibis eat?
D. The feathers are red because a wizard cursed the bid long ago

Answers

Answer 1

Answer: The answer is C because it seems like the most logical answer

Answer 2

Answer:

Final answer:

The hypothesis for what causes a scarlet ibis to have red feathers is that a chemical in the bird's food produces the red coloring.

Explanation:

B. A chemical in the bird's food produces the red coloring. In this case, the hypothesis suggests that the red feathers of the scarlet ibis are caused by a specific chemical component present in the bird's food. This hypothesis can be tested by conducting experiments to analyze the bird's diet and investigating the effects of different foods on the coloration of the feathers.

What is the advantage of genetic recombination as a mode of reproduction in bacteria? less time finding other bacteria

higher rates of reproduction

more susceptibility to antibiotics

greater genetic variation

Answers

Bacterial genetic recombination is characterized by DNA transfer from one organism called donor to another organism as the recipient and the result is the production of genetic recombinants, individuals. Those recombinant bacteria have a greater genetic variation because they carry, not only the genes they inherited from their parent cells but also the genes introduced to their genomes. There are three types of mechanisms that create genetic variations in bacteria (through recombination):

1. Transformation-that occurs when bacterium takes up a piece of DNA floating in its environment,

2. Transduction-occurs when DNA is accidentally moved from one bacterium to another by a virus (bacteriophage) and

3. Conjugation- when DNA is transferred from one bacteria to another through a tube between cells.

Those mechanisms of genetic recombination together with short generation time and random mutations allow bacteria to evolve very quickly and for example, create resistance to antibiotics.

The correct answer for the question that is being presented above is this one: "greater genetic variation." The advantage of genetic recombination as a mode of reproduction in bacteria is that it has greater genetic variation. The greater its genetic variation, the greater advantage of genetic recombination.

Which type of selection leads to increased phenotypic and genetic variation? directional selection disruptive selection stabilizing selection species selection

Answers

The circumstance that concludes whether the organism will be able to accommodate and endure in the changed conditions is called selection.

The correct answer is:

Option B. Disruptive selection.

This can be explained by:

Disruptive or diversifying adaptation occurs when there is a change in population genetics in which the traits are valued over intermediates.

This type of assortment supports either the dominant or the recessive trait but do not favour intermediates.

For example, in selection between tall, short or intermediate organisms the tall and short will be selected over the medium heightened organism.

Therefore, disruptive selection will lead to increased phenotypic and genetic variation.
