<h3>What is a hypothesis?</h3>

A hypothesis is a tentative explanation that is put forward for an observation. In this case, we have to determine whether the location or the kind of breed affects the color of the flowers.

To test the hypothesis, various shades of colors of the flower may be planted on different locations and the growth of each of the shades monitored to ascertain whether the color depends on the location or solely on the kind of breed.

5. The heat of fusion of lead is 25 J/g and its melting point is 601 K. How much heat is given off as 3.0 g
PIT_PIT [208]

Answer:

the heat given off is 75 J.

Explanation:

Given;

latent heat of fusion of lead, L= 25 J/g

mass of liquid lead, m = 3.0g

The heat given off is calculated as;

H = Lm

Where;

H is the quantity of heat given off

H = 25 x 3

H = 75 J.

Therefore, the heat given off is 75 J.

Use the picture below to answer the question. What is true about the relationship between the wavelength and the frequency of th
KatRina [158]
The picture is not loading as it requires a sign in.
However, I can tell you how to solve this.

Answer:
<span>As the wavelength gets shorter (closer together), the frequency of the wave increases. 

Explanation:
The relation between frequency and wavelength can be described by the help of velocity as follows:
velocity = frequency * wavelength
This means that:
frequency = velocity / wavelength
Noting this equation, we will find that:
The frequency and the wavelength are inversely proportional to each other. This means that as the frequency increases, the wavelength decreases and vice versa.
Now, examining the choices given, we can find that the only statement showing the inverse relation between frequency and wavelength is:
</span><span>As the wavelength gets shorter (closer together), the frequency of the wave increases. 

Hope this helps :)

marta [7]

Answer:

Due to random assortment and incomplete dominance of alleles.

Explanation:

The bunnies end up with ear thicknesses that are different from one another due to random assortment of alleles during gamete formation according to Mendel.

In addition to random assortment, the allele for thick ear also displayed what is known as incomplete dominance over the allele for thin ear to arrive at an average ear thickness.
