After complex organic molecules have been absorbed in the small intestine, what materials are left behind?

Answers

Answer 1

Answer: The answer is water and cellulose.

Some parts of the food cannot be absorbed, so they left behind in the guts so they can later be excreted. Humans cannot digest cellulose because of the lack of some symbiotic bacteria that are able to digest it (such as cows have). Water is later resorbed in the large intestine, so it will pass excretory system (kidneys and associated tissues) before excreted. Therefore, cellulose and water will not be absorbed in the small intestine.

What component of the circulatory system is at the tissue level? a. blood b. white blood cell c. heart d. hemoglobin

Answers

Answer;

A. Blood

Explanation;

The main organs of the Circulatory system are the heart, the brain, the lungs. There are other key things like arteries, veins, and capillaries but they are not organs.

The major tissues in the circulatory system are the epithelial, muscle, nervous, and connective tissues.

Blood is the main connective tissue in the circulatory system, but it's a liquid connective tissue. Blood tissue is in the same family as bone and cartilage, but instead it has a liquid medium that holds it together.

I belive it is a, because blood is a tissue.

What two processes fuel the carbon cycle?

Answers

Answer:

The two processes that fuel the carbon cycle are photosynthesis and cellular respiration.

Photosynthesis is the process by which carbon obtained from carbon dioxide (atmosphere) is fixed into the biomass (glucose or food).

This food or carbon content is then passed to animals through the food chain and to fossil fuels through decomposition.

This food or carbon content is then used by cellular respiration which releases carbon dioxide back into the atmosphere.

In addition, the burning of fossil fuels also releases carbon dioxide back into the atmosphere.

The two processes that fuel the carbon cycle are photosynthesis and cellular respiration.

The virus that causes mumps in humans is composed of a protein outer shell containing a core of DNA. The virus that causes the flu in humans is composed of a protein outer shell containing a core of RNA. Vaccines that are effective against mumps work efficiently year after year. Vaccines that work against the flu must be revised and changed every year. What accounts for the difference in the effectiveness of these two vaccines?

Answers

Flu vaccines need to be revised and changed every year because the flu virus constantly mutates. Flu viruses can change in two ways: drift or shift. Antigenic drift occurs when genes of the virus slowly change during replication until the immune system no longer recognizes it. On the other hand, antigenic shift occurs when a major change in the virus happens. This usually leads to a totally different kind of virus. This is what happened during the H1N1 scare in 2009.

DNA viruses like mumps are less prone to mutation due to the presence of DNA polymerase. RNA viruses are more prone to mutation because they undergo reverse transcription to simulate the role of DNA.

Assume that a mutation occurs in the gene responsible for the production of hexosaminidase a, such that only about 50% of the enzyme activity is found in the heterozygote compared with a homozygous normal individual. if heterozygotes are phenotypically normal, we would say that the mutant allele is recessive to its normal allele.
