Summarize how the functions of organelles in animal cells and plant cells are the same and different.
Alex_Xolod [135]
<span>Plant and animal cells have different structures. One structural difference of plant cells and animal cells is the presence of the plant cell’s </span>cell wall,<span> specialized plastids and a large central vacuole which are not found within animal cells.

Another difference is the garbage disposal of each cell. Centrosomes and lysosomes are found in animal cells but both do not exist within plant cells. The animal cell’s garbage disposal takes place in the lysosome while garbage disposal of plant cells takes place in the vacuole.</span>

Alexxandr [17]

To identify the molecule that accepts CO_{2}, Calvin and Benson manipulated the carbon-fixation cycle by either cutting off CO_{2} or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. The CO_{2} acceptor concentration would increase when the CO_{2} is cut off, but decrease when the light is cut off.

The correct option is d.

The process through which living things absorb inorganic carbon from the atmosphere and transform it into organic molecules is known as carbon fixation. These substances are employed as chemical energy storage. For life to continue, it is a necessary process.

Calvin and Benson disrupted the carbon-fixation cycle by either removing CO_{2} or removing light from cultures of photosynthetic algae in order to find the molecule that takes CO_{2}. Following the alteration, they evaluated the concentrations of several metabolites.

Prior to the advent of multiplex genetic testing, a person would have been most likely to have a genetic test to determine if th
Sloan [31]

Answer: Colon cancer

Explanation:

All cancers, but especially colon and rectal cancers, commonly referred to as colorectal cancer (CRC), have hereditary factors that potentially increase one’s risk.

Genetic testing is determine if there is an increased risk of colon cancer. Apolipoprotein E (apoE) plays a major role in the metabolism of bile acids, cholesterol and triglycerides, and has recently been proposed as being involved in the carcinogenic process. Given the potential role of bile acids in colorectal cancer etiology, it is reasonable that colorectal cancer risk might be modified by apoE genotype. The absence of an e3 apoE allele significantly increased the risk of colon cancer especially for individuals above 50years.
