Compared with fraternal twins, identical twins are similar in neuroticism, extraversion, and temperament

Are identical twins actually fraternal twins?

Fraternal twins are not identical twins since they were created when two different eggs were fertilized by two different sperm cells at the same time. Identical twins are produced when a fertilized egg divides in two; one egg, one sperm, and two offspring.

Why are fraternal twins special?

Identical or monozygotic twins share 100% of their DNA, whereas fraternal twins only share about 50%. They are therefore genetically identical to non-twin siblings.

How rare is it to have a fraternal twin?

The likelihood of having identical twins is about 3 in 1,000 worldwide, while the prevalence of fraternal twins varies by region and might be anywhere from 6 and 20 per 1,000 deliveries.

Answer:

<em>The correct option is D) How is the number of frogs in Massachusetts affected by pollution</em>

Explanation:

A scientific question can be described as a question which can be answered through the scientific method of research. Based on the scientific question, a hypothesis can be formulated. For example, for the option D, the hypothesis can be 'if the pollution increases, then the number of frogs decreases.' A hypothesis is a tentative statement which can be tested through experiments. Based on these experiments, results are formulated and conclusions are drawn. The question mentioned in option D can be answered through this method hence, it is the correct option.

Why is e = hv important in pv cell considerations?

Zanzabum

E=hv is an equation important when dealing with light. E refers to the energy of a photon; h is Planck's constant and v is the wavelength. According to this equation, light particles called photons travels in packets of energy. This is important in pv cells because this is the technology used to harness solar energy which is converted to electricity. The amount of energy should be estimated to know the appropriate material of construction of the pv cell to achieve optimum conditions. In this way, the pv cell could maximize the sun's energy.
