Answer: Noting the color of the solution as it is heated.
Explanation: All other choices are examples of quantitative data. As in the measuring of a quantity(mass, volume, temperature). The last choice is an observation that cannot be easily converted into a numeric form.
Answer:
Convection process
Explanation:
The process of convection is commonly takes place in the mantle portion of the earth and also at the atmosphere.
This process is usually defined as the process where the materials are heated at a high temperature, thereby making them less denser, and due to their low density they are gradually pushed upward into the upper zones. As the materials rises up, the density gradually increases due to the lowering of the temperature, and then the materials again sinks. This give rise to the formations of a circulating cell, which are commonly known as the convection cells.
Answer:
a) 
b)

c) 
Explanation:
Given ,
Frequency of white flower plant (
) is 
Thus, frequency of dominant white allele (
) is equal to 
As we that, as per Hardy-Weinberg equilibrium equation

Substituting the value of
in above equation, we get

a) As per Hardy-Weinberg equilibrium equation

Substituting the given and calculated values in above equation, we get -

b) The frequency (decimal form) of the dominant allele

c) number of homozygous purple flower plants
frequency of purple flower plants (
)
Number of flowers

C) is definitely the bacterium!
A) look like a paramecium with it's flagela and vacuole
B) is a plant cell with chloroplasts
D) could be an animal cell, plant, or fungal since it has a nucleus
**remember: bacteria lack ALL membrane bound organelles: nucleus, mitochondria, chloroplasts, E.R.!!
Answer:
Muscles use the stored chemical energy of food we eat and convert that to heat and energy of motion (kinetic energy). We need energy to enable growth and repair of tissues, to maintain body temperature and to fuel physical activity. Energy comes from foods rich in carbohydrate, protein and fat
