Answer:
- use of economical model organisms
- collaborating with other scientists with same interests
Explanation:
Using the field of biomedical research as a case study, scientists navigate through limited funding by:
1) trying their investigations on cheaply and readily available organisms such as yeast or worms like C. elegans rather than more complex and expensive higher organisms like wistar rats or Guinea pig
2) forming alliance with other notable scientists in nearby laboratories equipped with a resource or more that is unavailable insitu (at the main research lab)
The nucleus contains the dna
Answer:
Macroevolutionists cannot make direct observations because most of the organisms are dead or extinct.
Explanation:
only true one
The answer is A smaller fragments will move faster.
Answer: in order from small intestine to the rectum: 1, 4, 2 and 3.
Explanation: Ascending colon; the colic valve(the ileocecal valve) is located at the bottom of the ascending colon. At the top of the ascending colon, the colon bends to the left, forming the right colic flexure called the hepatic flexure. The transverse colon begins after this flexure.
The transverse colon; is the longest and most movable part of the colon which runs across the abdomen from the ascending colon at the right colic flexure with a downward convexity to the descending colon, here it curves abruptly on itself under the lower end of the spleen to form left colic flexure called the splenic flexure.
Descending colon; it start from the splenic flexure to the beginning of the sigmoid colon. The descending colon stores the remnant of digested food that will be deposited into the rectum.
Sigmoid colon; also known as pelvic colo is the closest to the rectum, it is a passage by which digested food move into the rectum.
