Answer:
1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .
2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body

The <u>urethra</u> is an organ which communicates with the lower bladder in order to enable excretion of urine from the body of a living organism.
<h3>What is an excretory system?</h3>
An excretory system refers to a living system that is saddled with the responsibility of removing waste products from the body of a living organism, so as to prevent damage to the body and help maintain homeostasis.
Based on scientific information, the <u>urethra</u> is an organ which communicates with the lower bladder in order to enable excretion of urine from the body of a living organism.

Answer:
The process of decomposition increases the amount of carbondioxide gas in the atmosphere.
The process of decomposition greatly affect the amount of carbondioxide in the atmosphere because in the process of decomposition, carbondioxide is released in the atmosphere which is added to the carbondioxide present in the atmosphere.
This results in more warm temperature of the earth atmosphere so we can conclude that the process of decomposition increases the amount of carbondioxide gas in the atmosphere.

Answer:
E. Nucleus
Explanation:
All living organisms were classified into three major domains viz: Eukarya, Archaea and Bacteria. Eukarya are referred to as EUKARYOTES while the other two domains are collectively referred to as PROKARYOTES.
The major basis of this classification is the presence or absence of a membrane bound NUCLEUS. Eukaryotes are organisms characterized by the possession of a membrane-bound nucleus that houses their genetic material (DNA) while prokaryotes lack a nucleus and hence, their genetic material is found naked in the cytoplasm. Although, prokaryotic cells lack other membrane-bound organnelles like Chloroplast, mitochondria etc. but nucleus is the basis of this classification:
EU meaning TRUE, KARYA meaning NUCLEUS, hence Eukarya means organisms will true nucleus.
<h2>Simple Interest on a Loans - Option C</h2>
The simple interest on loans of $200 at 10 percent interest per year is $20 per year until the loan is paid off. Interest per year means the expense of interest that is charged for annum as a percentage of the value which is hired.
In order to calculate interest per year, multiply the principal basis for the rent by the interest per year then divide the value of interest per year by 12 (number of months in a year). Therefore, for simple interest on loans of 200 dollars at 10 percent interest per year, we calculate 20 dollars per year until the loan is paid off.
