Answer:
Explanation:
Wood has_chemical energy_____ energy while a burning fire has__heat energy __ energy
Wood is a material that makes up the central part of the trunk and branches of trees. Wood is made up of complex hydrocarbons and a rich cellulose network of organic molecules. A wood stores chemicals energy.
Combustion process such as burning liberates heat energy in them. Burning occurs in the presence of oxygen. As the oxygen combines with the materials, heat becomes liberated to the surroundings. Burning is an exothermic process in which heat energy is liberated.
Answer:
A cell needs nutrients for its survival. Complex nutrient molecules, such as sugars and proteins, are taken into the cell and broken down into simple, usable molecules by cellular enzymes. These simple molecules provide the required energy to the cell for its survival. Which organelles are most responsible for taking in and breaking down the nutrients for the cell?
LYSOSOMES
Explanation:
Lysosomes helps to breakdown food materials such as carbohydrates, protein among others as well as breakdown cell when it dies. It is helpful in this breaking down in order to get usable molecules by cellular enzymes
Answer
<em>The correct option is determining the size of the fire coral population in a quadrat sample area and using it to estimate the overall population size
.</em>
Explanation:
Quadrat can be described as a method to calculate the size of individuals of a population. A quadrat is an instrument which has a square shape which is used by statisticians to measure the distribution of population in a unit area. By counting the number of individuals in the quadrat, the number of individuals in the whole area can be calculated.
It is an effective method because counting each individual from a population becomes extremely tiresome and may not be possible for larger populations.
