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: This means that this sentence is a statement

Explanation:
All living organisms need nutrients to survive. While plants can obtain nutrients from their roots and the energy molecules required for cellular function through the process of photosynthesis, animals obtain their nutrients by the consumption of other organisms. At the cellular level, the biological molecules necessary for animal function are amino acids, lipid molecules, nucleotides, and simple sugars. However, the food consumed consists of protein, fat, and complex carbohydrates. Animals must convert these macromolecules into the simple molecules required for maintaining cellular function. The conversion of the food consumed to the nutrients required is a multistep process involving digestion and absorption. During digestion, food particles are broken down to smaller components, which are later absorbed by the body. This happens by both physical means, such as chewing, and by chemical means.
One of the challenges in human nutrition is maintaining a balance between food intake, storage, and energy expenditure. Taking in more food energy than is used in activity leads to storage of the excess in the form of fat deposits. The rise in obesity and the resulting diseases like type 2 diabetes makes understanding the role of diet and nutrition in maintaining good health all the more important.
