During an experiment, a scientist crosses a pea plant that has purple flowers with a pea plant that has white flowers. The plants that result from this cross in the F1 generation have both purple and white flowers. What can the scientist conclude?

Let's say the dominant colour is purple (P) and the recessive colour is white (w).
The purple plant may be $PP or Pw$
The white plant can only be $ww$

Then we have $Pwxxww->Pworww=$flowers of both colours

A homozygotic purple would only produce purple flowers:

$PPxxww->Pw=$ purple

When first-generation plants are allowed to self-pollinate, what type of traits appear in the second generation?

Self-pollination means that you are not necessarily introducing any new traits into the second generation. Say you have a heterozygote plant for smooth seeds (i.e. Ss). This means, that...

A plant can produce either purple flowers or white flowers. What is the probability of purple-flowered offspring if two plants that are heterozygous for purple flowers are crossed?

Let us consider a cross between two plants heterozygous for purple flowers. Heterozygous Purple (Pp) X Heterozygous Purple (Pp) Each plant will produce two types of gametes, i.e. 50%...

During an experiment a scientist poured a 0.256-liter solution into a beaker. Four- hundredths of the solution was alcohol. How many liters of the solution was alcohol?

I have assumed that the volumes of alcohol and water are additive; which is good enough for a first approximation. So if it's a $"4%"$ solution, $"volume of alcohol"$ $=$...

A scientist measured the wavelength of an orange light was at $6.15 * 10^-7$ meters. A second scientist measured the wavelength of a green light as $5.6 * 10^-7$ meters. How much longer is the orange wave than the green wave?

Unless I'm missing something important here, you can find the difference between the two wavelengths by subtracting one from the other. Since you're interested in finding how much longer...
