Answer:
B. Water evaporates more quickly when temperatures are high
Explanation:
Constructing an hypothesis is KEY to any experimental setup. It is the first thing to do in accordance to the scientific method. A hypothesis is simply a predicted statement that aims at proferring solution that is subject to testing via experimentation.
According to this question, Mae observed that the birdbath in her backyard loses water more quickly during hot summer days than during the cooler days of the spring. A suitable hypothetical statement for this observation would be: "Water evaporates more quickly when temperatures are high".
N.B: Hypotheses are not questions
Answer: Heat ---from a warmer substance to a cooler substance
Explanation: Heat can be transferred from a hotter substance to a cooler substance. This can be done through three methods;
Conduction, Convention, Radiation
Conduction- When substance is been heated movement of particles increases causing collision between hotter particles and cooler particles. This continue until the temperature is in equilibrium. Metal is a good conductor of heat.
Convention- It is often associated with liquid and gases. hotter area of liquid moves and meet with cooler liquid. The cooler liquid then takes place of the hotter liquid until equilibrium is attain. This occurs while boiling water
Radiation - It doesn't need a means of transmission. It is gotten from infared emission. Infared emission increases when temperature increases .
Answer: The answer is C The red potatoes have approximately a 0.37 M solute concentration because this is where the potatoes would neither gain nor lose mass.
Explanation:
Normal proteins allow the substances Na + and Cl- to move correctly through the cells of the skin, the pancreas and the lungs.
In contrast, the mutated proteins prevent them from moving through the cell, this causes mucus to accumulate in the skin, in the lungs and the pancreas, a medical condition called cystic fibrosis.
