Giraffes with short necks lived in arid regions. Over time, grasses disappeared, forcing giraffes to eat from trees. Mutations i

n the genome led to some giraffes inheriting the trait for long necks. Over time, there were more giraffes with long necks in the region. What are the two reasons for the change in the population of giraffes? (More than one answer)
- adaptation?
- artificial selection?
- natural selection?
- harmful genetic traits?

I think it would be adaptation and natural selection because both the terms are when an animal adapts to their environment. I hope this helps!

Answer: adaptation

natural selection

Natural selection refers to the differential survival of the organisms in the population. It describe the fact that individual that have favorable phenotypic characteristics have better chances of survival over others in the changing environment. Adaptation is a genetic change or mutation that helps organism to survive in it's ecological niche. Due to the helpful nature of these genetic changes they are passed down from one generation to the next generation and favors the survival and abundance of a species.

Adaptation and natural selection has resulted in the change in the population of the giraffes. The giraffes being in short neck adapted the increase in neck length with an effort to obtain leaves from tall tries. The long neck giraffe got the better chances of survival and reproduction, due to natural selection the trait was passed on to generation. This resulted in the evolution of long neck giraffe species.

What is the value of the equilibrium constant at 25 oC for the reaction between the pair: I2(s) and Br-(aq) Give your answer usi
insens350 [35]

Explanation:

Formula to calculate standard electrode potential is as follows.

          E^{o}_{cell} = E^{0}_{cathode} - E^{0}_{anode}

                             = 0.535 - 1.065

                             = - 0.53 V

Also, it is known that relation between E^{o}_{cell} and K is as follows.

            E^{o}_{cell} = \frac{RT}{nF} \times ln K

                 ln K = \frac{nFE^{0}_{cell}}{RT}      

Substituting the given values into the above formula as follows.

                 ln K = \frac{nFE^{0}_{cell}}{RT}    

                        =  \frac{2 \times 96485 C mol^{-1} \times -0.53 V}{8.314 l atm/mol K \times 298 K} \times \frac{1 J}{1 V C}  

                ln K = -41.28

                    K = e^{-41.28}    

                        = 1 \times 10^{-18}

Thus, we can conclude that the value of the equilibrium constant for the given reaction is 1 \times 10^{-18}.

Describe in general terms the structure of ionic solids such as nacl
allochka39001 [22]
<span>Ionic compounds are chemical compounds in which ions are held together in a lattice structure by ionic bonds. They have a high melting and boiling point, and they have a high hardness and are very brittle. The cations and anions are stuck together in a sense. So in this case, sodium (Na) is attracted to Chlorine (Cl).</span>
