Answer:
The mouth and teeth break up the food and mix it with saliva.
Answer:
stomach
Explanation:
The stomach is like a mixer, churning and mashing together all the small balls of food that came down the esophagus into smaller and smaller pieces. It does this with help from the strong muscles in the walls of the stomach and gastric (say: GAS-trik) juices that also come from the stomach's walls.
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.
pathogenic bacteria
aerobic bacteria
rickettsia
Answer:
The correct answer would be nitrogen-fixing bacteria.
Nitrogen-fixing bacteria live in symbiotic relationship in the roots of plants especially leguminous plants such as peanuts, soybean, pulses et cetera.
The symbiotic bacteria live in the root nodules of the plants.
It helps in fixing the atmospheric nitrogen and converts into the forms which can be used by plants.
In return, plants provide the bacteria with shelter and food (glucose).
Example of symbiotic bacteria would be rhizobia
b. False
Answer:
False
Explanation:
People suffering from HIV/AIDS face taboos as they are considered as someone suffering from a non treatable disease which may spread if they are in contact with the affected person. Though there are several awareness campaign, which are run (by government, private agencies/NGOs) just to make people aware that this disease is not communicable but yet people consider it as communicable disease. Hence, some one who is having HIV/AIDS is not at all treated as an uninfected individual in society.
Hence, the given statement is false.
Answer:
The process of digestion in the human body takes place over six (6) steps. This travel log would be documented with each chapter as a step:
Day 1: Ingestion. I do not know how I got into this dark wet room (mouth) with huge white grinders (teeth), but I do not believe I would make it out in one piece; these grinders keep mashing me up n what I believe to be 'chewing'.
Day 2: Propulsion. There's a tunnel (oesophagus). I feel like I'm going down a wet slide.
Day 3: Physical digestion. I think I'm in some sort of sac-like mechanism (stomach)with thick walls that produce some sort of toxic substance (acids and enzymes) to my body. This is where I die.
Day 4 and 5: Chemical digestion and absorption. There is almost nothing left of me; I am being taking in by the walls of this maze (small intestine). More of the 'toxic' substance is coming from what appears to be leaf (liver) and all my constituents are being disintegrated (by the duodenum). Now there's a larger maze (large intestine or colon). I'm being separated and completely absorbed. The things that aren't useful about me (waste/stool) are being sent away.
Day 6: Defecation. Waste is excreted in the nus through the rectum.
I hope this was helpful.
Answer:
Glycolysis.
Explanation:
Aerobic respiration involves complete breakdown of glucose molecule in the presence of oxygen to release 36 molecules of ATP. On the other hand, anaerobic respiration involves partial breakdown of glucose molecule, when oxygen is absent to release only two molecules of ATP.
Glycolysis is a universal process as it is common in both aerobic and anaerobic respiration. It does not require oxygen and can occur in both presence or absence of oxygen. Glycolysis forms two [pyruvate molecules, two ATP molecules. along with two NADH molecules from one glucose molecule.
Thus, the correct answer is 'glycolysis.'
Both aerobic and anaerobic respiration involve the breakdown of glucose for energy, but aerobic respiration requires oxygen and produces carbon dioxide and water, while anaerobic respiration occurs without oxygen and produces either ethanol or lactic acid.
Aerobic respiration and anaerobic respiration are two different processes that cells use to generate energy, but they share some similarities. Both processes involve the breakdown of glucose molecules to release energy in the form of ATP (adenosine triphosphate). Additionally, both processes occur in the cytoplasm of cells and involve the initial step of glycolysis, where glucose is converted into pyruvate.
However, the key difference between aerobic and anaerobic respiration lies in the final steps. Aerobic respiration requires oxygen and proceeds with the conversion of pyruvate into carbon dioxide and water through the Krebs cycle and the electron transport chain in the mitochondria. In contrast, anaerobic respiration occurs in the absence of oxygen and follows either alcoholic fermentation or lactic acid fermentation, where pyruvate is converted into either ethanol or lactic acid, respectively.
