Which observation would be evidence for allopatric speciation among finch species of the Galápagos Islands?

Biology

Answer:

The correct answer is c. Specific beak sizes are adaptations to the seeds of different species.

Explanation:

Allopatric speciation occurs when a population of a species is isolated geographically from their group. Then these isolated populations evolve in different species due to the selective pressure of natural selection.

The best example of allopatric speciation is seen in finches that live in the Galapagos Islands. These finches are isolated due to oceans on different islands of Galapagos and they developed different types of beaks according to the food they get on their island.

Some developed large blunt beaks to crack nuts, some developed long beaks to eat flowers and due to geographical isolation they did not interbreed and developed into a new species of finch. Therefore the correct answer is c.

Solve for v<br>negative 38= v/2
Nadusha1986 [10]

- 38 =  \frac{v}{2}



\text{Multiply by 2 on both sides,  }


2 \times ( - 38) =  \frac{v}{ \cancel{2}}  \times  \cancel{2} \\  \\  \\  \\  =  >  - 76 = v \times 1 \\  \\  \\  =  >  - 76 = v


So, value of v is - 76

Answer:

The Answer is,  B, C, And E. I just took it on USATESTPREP.

B) G3P can be used to form the backbone of triglycerides. Glycerol combines with fatty acid tails to form lipids.

C) Two G3P molecules can be combined through anabolic processes to form glucose, a six-carbon sugar required by cells.

E) G3P can be used in to synthesize amino acids, which contain a central carbon, a carboxylic acid group, and a variable R group. These amino acids can then combine to form proteins.

Of the following lists of electron transport compounds, which one lists them in order from the one containing electrons with the
notsponge [240]

Answer:

B) FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2

Explanation:

FADH2 and NADH give their high energy electrons to the terminal electron acceptor molecular oxygen via an electron transport chain. As the electrons move through electron carriers of the electron transport chain, they lose their free energy. Part of the free energy of the electrons is used to pump the protons from the matrix into the intermembrane space. Therefore, part of the energy of electrons is temporarily stored in the form of a proton concentration gradient.

NADH gives its electrons to FMN of complex I while FADH2 gives its electrons to the Fe-S center of complex II. Both the complexes are oxidized by coenzyme (Q) which in turn reduces Fe-S centers of complex III. Cyt c of complex IV obtains electrons from complex III and passes them to CuA center, to heme "a" to heme "a3-CuB center" and finally to the molecular oxygen.

So, the compounds arranged with respect to the energy content of electrons in descending order are as follows: FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2.
