Answer:
The difference between an independent variable and a dependent variable in an experiment is that the independent variable is the one that the researcher will change or alter in order to test the effects of the change on the dependent variable. The purpose of the experiment is to observe the relationship between changes in the independent variable and changes in the dependent variable. If the dependent variable changes as a result of the changes in the independent variable then the researcher knows that the two variable has a relationship.
Explanation:
b. Plantae
c. Fungi
d. Protista
Answer:
True
Explanation:
The DNA sequence determines the protein that is going to be produced. The first step is the transcription where DNA sequence is transcribed to mARN. After the mARN is formed this will go out of the nucleus and into the cytoplasm. In the cytoplasm the mARN, together with the tARN and the ribosome will make a protein by a process called translation. In this process the ARN sequence is read to give and join the amino acids that are required to form the protein.
Answer:
C. Bronchial
Explanation:
The different types of lung sounds, also known as breath sounds differ from each other with respect to their location, pitch, relative duration, and intensity.
The bronchial breath sounds are heard just above the clavicle on either side of sternum bone and are characterized by loud amplitude, harsh quality, and high pitch. The bronchial breath sounds are hollow tubular.
The bronchial breath sounds have a short period of silence between the inspiratory and expiratory sounds. The expiratory bronchial sounds last longer than the inspiratory bronchial sounds (I<E).

A person with an immune system which is weakened may not be able to fight against infection reason being that the white blood cells which makes up the immune system, fighting off infection and protecting the body against disease which cause organisms are weak.
For a person to be able to fight disease the immune system should be highly complex. For health maintenance thee should be balanced and strong immune system.
Impaired immune response can pose to a serious bad health.
To avoid the influence of immune someone should avoid emotional stress, environmental and chemical exposure and physical stressors for example lack of enough sleep.
Answer:
His immune system cannot fight against invading pathogens.
Explanation:
Weaken immune system represents a state of immunodeficiency, in which immune system of an individual fails to fight properly with infections and cancer.
This is due to inability of body to make functional immune cells, such as neutrophils, T cells, B cells, and macrophages or decreased production of these cells and other components of immune system that provide protection against invading pathogens.
