An ameba is a single-celled organism. It uses its cell membrane to obtain food from its environment, digests the food with the h

elp of organelles called lysosomes, and uses other organelles to process the digested food. From this, we can best infer that
(1) all single-celled organisms have lysosomes to digest food
(2) amebas are capable of digesting any type of food molecule
(3) single-celled organisms are as complex as multicellular organisms
(4) structures in amebas have functions similar to organs in multicellular organisms

Describe how C. parvum obtains the glucose it needs for glycolysis after it has infected another cell. Explain the role of lacta
ch4aika [34]

Answer:

C. parvum takes energy from glucose which is present in the digestive tract after the process of glycolysis.

Lactate dehydrogenase which is responsible for the conversion of lactate into pyruvate molecule.

Explanation:

C. parvum is a protozoa that lives as a parasite in the digestive tract of animals. They take nutrients from the cell which are present in the form of glucose. C. parvum uses a specific type of enzyme i. e. lactate dehydrogenase which is responsible for the conversion of lactate into pyruvate and also helps in the production of ATP through glycolysis process. In this process, the glucose molecule is broken down into two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water. So C. parvum takes ATP from that way from the host cells.

What is your hypothesis regarding difference in urine "chloride" concentration between subjects who drank water and subjects who
Sedbober [7]

Answer:

Chloride concentration in urine is more who drank sport drink as compared to a person who drank normal water.

Explanation:

Chloride concentration in urine is high who drank sport drink as compared to a person who drank water because in sport drink there is more concentration of salts are present which is required our body. Due to more salts present in the sport drink, more chloride is present in urine due to the removal from the body while normal water has less amount of salts so urine has less concentration of chloride in urine.

What is the work generated by a healthy adult who circulates 9 l of blood through the brachial artery in 10 min 2 kj?
Pani-rosa [81]
You have also the total power generated is 200W

To figure out the kind of exercises, you need to master the definition of each unit. for example
power: watt (W) is joule/sec
Work: is Newton. meter = Joule

To obtain the work done by the adult, we have to convert the power (watt) into a work by multiplying by the time  (\frac{Joule}{seconds}  * seconds = Joule)
10 minutes is 60 * 10 = 600 seconds

200Watt * 600 second = 120000 joules = 120 Kj

So the work is 120Kj
