Xenotransplantation is using nonhuman animal organs in transplantation. Many people are against this practice. What would be the

best argument for why xenotransplantation should be accepted?
A. There are more people on transplantation lists than donor organs so xenotransplantation can save people’s lives

B. People on transplantation lists are not treated equally in that some are moved to the top of the list

C. There are no antigens on the surface of nonhuman animals so there would be no rejection

D. More organs can be extracted from nonhuman to accommodate more recipients

Answer:

A. There are more people on transplantation lists than donor organs so xenotransplantation can save people’s lives

Explanation:

Xenotransplantation, ie using non human animal organs in transplantation, has following most crucial favouring argument

  • Patients needing transplanted organs are much higher than people willing & able to donate them. So, there is extreme excess demand, needed to be satisfied for saving people's lives.

Answer:

The digestive system!

Explanation:

The digestive system is made up of the digestive tract - a series of hollow organs joined in a long, twisting tube from the mouth to the anus - and other organs that help the body break down and absorb food.

Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine - also called the colon - rectum, and anus.

Please help I can’t figure this out

Answer:

Photosynthesis is the process in which cells use carbon dioxide and water to make glucose in the presence of sunlight.

Respiration is the process in which glucose molecules are utilized to release energy in the form of ATP.

Explanation:

Ans1- Respiration in cells occurs in mitochondria.  Cells gain energy in the form of ATP. Conversion of glucose in the form of ATP is known as cellular respiration.

Cellular respiration can take place either in presence of oxygen(aerobic respiration) or in absence of oxygen(anaerobic respiration ).

Before entering into cellular respiration glucose molecule has to be converted into pyruvic acid. This process in known as GLYCOLYSIS.

<em><u>Anaerobic respiration</u></em> occurs in mitochondria when oxygen is not present. It is known as fermentation.It is not effective process to produce ATP from glucose as in this process only 4 ATP can be released.  

<u><em>Aerobic respiration</em></u> occurs in mitochondria in presence of oxygen.  This is effective pathway to gain ATP as it releases 36 ATP from 1 glucose molecule.

Ans2- All cells which has photosynthetic pigments are able to use photosynthesis. Example- Blue green algae, cynobacteria etc.

Ans3- We can see different shades of green colors of plants and leaves because of different types of chlorophyll present in plant. Chlorophyll are of 6 types in plant. Their types are based on the lights they absorb. Two main types of chlorophylls are chl a and chl b.

Ans4- Both plant and animal cells have mitochondria. In plant also they need energy. To get ATP from breakdown of glucose respiration is occur in plant also.

Ans5-In photosynthesis glucose is formed from water and carbon di oxide. 6 carbon dioxide and 6 molecules of water are used to make 1 molecule of glucose. Water and carbon di oxide are reactant in this process.

Ans6 -  Cells without oxygen can burn glucose to release energy. This process is known as Anerobic respiration/ fermentation. But the outcome of energy is lower than aerobic respiration. ( ANS1)

Ans7- In the process of photosynthesis reactants are water and carbon di oxide. Oxygen produced released in the form of gas along  with carbon di oxide.

Ans8- The enzymatic reaction of respiration occurs in mitochondria. Krebs cycle occurs in the matrix of mitochondria.( ETC electron transport chain) to release ATP occurs in cristae of inner membrane of  mitochondria.

Ans9- Plants make glucose through photosynthesis . In  presence of sunlight plants use carbon dioxide and water to make sugar.
