Answer:
c) Both are functions of blood, that is, to carry oxygen to the cells and also remove wastes from the body.
Explanation:
Blood is a form of connective tissue and is made up of red blood cells, white blood cells, platelets and blood plasma. The red blood cells contains a metallo-protein structure known as hemoglobin. This hemoglobin binds to the oxygen and carry them to the cells and the tissues for proper functioning of them. The waste products like carbon dioxide is carried by the blood from the body tissues to expel it out from the body.
Answer:
C. Larger compounds break down into two or more smaller compounds.
Explanation:
During a decomposition reaction, the bonds between the atoms break down in the starting substance. The atoms then rearrange to form new bonds, resulting in new substances with properties different from the starting material.
Answer:
This question is incomplete, based on the given hypothesis, the question is asking to identify the variables (independent and dependent) of the experiment.
*Independent variable: DIFFERENT SOILS
*Dependent variable: Porosity
Explanation:
- Independent variable is the variable that is manipulated or changed by an experimenter in order to effect a response in another variable. In this question, three different soils were used, hence, the SOIL is the independent variable.
- Dependent variable is the variable that responds to changes made to the independent variable. It is the variable being measured in an experiment. In this case, the porosity is the variable being measured, hence, it is the dependent variable.
Answer:
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
Explanation:
A cell wall is a rigid, semi-permeable protective layer in some cell types. This outer covering is positioned next to the cell membrane (plasma membrane) in most plant cells, fungi, bacteria, algae, and some archaea.
