Intercostal Muscles
The muscles of respiration
are muscles that contribute to exhalation and inhalation by causing the contraction
and expansion of the thoracic cavity. However, diaphragm is the main muscle of breathing
while intercostal muscles is one of the most important muscles for respiration.
Intercostal muscles function by manipulating the width of the rib cage and they
are attached between the ribs.
Answer:
Obligate anaerobes (Ans. D)
Explanation:
Gas gangrene is a bacterial infection which produces tissue gas in gangrene. This is caused by bacteria <em>Clostridium perfringens</em><em>. Clostridium perfringens</em> is a gram-positive, obligate anaerobic bacterium of the <em>Clostridium</em> genus. It is found in environmental sources & commonly found in raw meat and poultry.
Tetanus is a bacterial disease infected by <em>Clostridium tetani</em>, is an obligate anaerobic spore-forming bacteria. It is found in soil, dust and intestinal tracts of animals. Transmission of tetanus is commonly by contaminated wounds.
Answer:
i think answer B is correct
The Antidiuretic hormone ( ADH ) affects the kidney tubules tp bring about the reabsorption of water in the glomerular filtrate.
Thus, the Antidiuretic hormone ( ADH ) also play a vital role in the kidney in homeostasis
<h3>What is homeostasis?</h3>
Homeostasis can simply be defined as the steady maintenance of the internal environment of an organism. Living organisms usually find a way to balance any low or high concentration of substances in the internal environment
Below are what makes up the internal environment of an organism:
- Blood
- Lymph
- Intercellular fluids
So therefore, cell structures involved releases glucagon to raises the blood glucose levels when the glucose levels in the blood is low

Ozone is formed by the reaction of of nitrous oxides and reactive organic substance catalyzed by sunlight. This is a photochemical reaction provided with ozone forming compounds and sunlight.
Acid rain is defined as nitrous(NO2) and sulfurous (SO2) compounds enter the atmosphere as smog thereby precipitating as acid rain. This is detrimental in the environment as well as in agriculture.
Global warming is precipitated by the burning of fossil fuels that increases carbon dioxide, a greenhouse gas that traps heat, in the atmosphere. The greenhouse effect is the main principle behind global warming.
Ocean acidification is when excessive carbon dioxide is dissolved in the oceans as carbonic acid thereby increasing the pH of the ocean. Increases in the pH of the ocean can affect the living conditions as well as industrial conditions near it.
Groundwater pollution is defined as contaminating the groundwater with the runoff from industrial agriculture including organic and inorganic wastes as well as infectious and nuclear wastes.
Algae blooms or algal blooms are precipitated by eutrophication or the increase in nutrients in water such as nitrogenous compounds and phosphorus from fertilizers. Eutrophication of water precipitates the abnormally high growth rate of algae.
Ozone layer destruction is associated with CFCs such as Freon and aerosols as these compounds neutralize and destroy ozone. These compounds form free radicals that convert ozone (O3) to oxygen (O2) thereby reducing its capability to protect the earth from UV radiation.
Deforestation is primarily caused by urbanization (cutting down trees to provide empty land in building structures) and industrial farming (converting forests into agricultural lands for farming).
