The answer to this question would be: <span>proceed through the trachea, bronchi, and then bronchioles.
After going pass the oropharynx the air will be going to trachea, </span>bronchi, bronchioles and will end in the alveolus. In alveolus, the oxygen from the air will diffuse to the blood while carbon dioxide will diffuse to the alveolus. The carbon dioxide is going out of the lungs when doing expiration.
Answer:
A decomposer is found at the end of a food chain.
Answer:
D) presence of transcription activators or repressors
Explanation:
The reason why this is not post-transcriptional regulation is that activators actually start the process of transcription by binding to specific sites. while on contrary when repressor binds it halt the process.
For example, there is a protein called CAP which in the presence of cAMP bind with promoter region and enhances the activity of RNA polymerase . While in the absence of cAMP it can not bind to promoter hence the transcription stooped.
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.
Answer:
Dominant
Explanation:
The dominant allele will always be shown in the phenotype if it's present, because the other allele would be dominant or recessive. If both alleles are dominant, then the dominant one shows, if one of the alleles is recessive, then the dominant allele would show over the recessive one.
I think of recessive alleles as "weak" where, they just follow behind whichever other allele exists there. If the other one is dominant, then the recessive one is behind it, and no one can see it. If it other allele is recessive, a recessive allele will be in front.
