On the Galápagos Islands, the finches that Darwin studied tended to have either small beaks or large beaks. The smaller beaks ar

e best at eating soft seeds but are ineffective at cracking large seeds. The larger beaks are best at cracking hard seeds. Beaks of intermediate size are inefficient for either seed type. Which result of natural selection is at work in this example?
A. stabilizing selectionB. directional selectionC. disruptive selectionD. individual selectionE. unnatural selection

Answer:

The correct answer is option C. "disruptive selection".

Explanation:

Disruptive selection is a type of natural selection at which extreme values for a trait are favored, while intermediate traits are more likely to disappear. In this example the finches tended to have either small beaks or large beaks because small beaks are best at eating soft seeds and large beaks are best at cracking seeds. This is an example of disruptive selection because the two extreme values for the size of beaks are favored.

What is so special about nitrogen in the atmosphere
HACTEHA [7]

Answer:

Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.

Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.

Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.

If the female fly has EE and the male fly has EE, what are the possible percentages of phenotypes and genotypes of their offspri
algol [13]

Answer:

100% EE, 100% red eyes

Explanation:

For an organism, the genotype refers to the genetic characteristics of the organism while the phenotype refers to the physical characteristics of the organism.

The red eyes (E) is dominant while the white eyes (e) is recessive.

Since both parents are EE, the genotype of their offsprings would be EE, EE, EE, EE

That is: EE × EE = EE, EE, EE, EE

Hence the genotype is 100% EE.

Also, the phenotype is 100 red eyes.
