the digestive system of most animals is lined with cells through which nutrients are absorbed. what is the embryonic origin of these cells?
Answer:
Further breakdown of food takes place in the small intestine where enzymes produced by the liver, the small intestine, and the pancreas continue the process of digestion. The nutrients are absorbed into the bloodstream across the epithelial cells lining the walls of the small intestines.we inhale o2 and we exhale co2. carbon dioxide is produced __________.
What is the importance of sea-floor spreading?
Answer:
Significance. Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere.

which division of the ans is referred to as the rest and digest division?
now you’ll examine an operon that undergoes negative and positive control. the ara operon in e. coli codes for enzymes that metabolize the sugar arabinose, which e. coli can use for energy. as you can see in the diagram, the regulatory protein arac can act as both an activator and a repressor of the ara operon.
The lac operon is known to be able to undergoes negative and positive control.
The diagram based on the 4 table arrangement is filled up below (Right to left);
In the presence of arabinose: initiator, activator, yes, yes.In the absence of arabinose: initiator and operator, repressor, no, no.
If a mutation prevents arabinose from biding to AraC: initiator and operator, repressor, no, no.
If arabinose is present but a mutation and AraD enzyme renders it non-functional: initiator, activator, yes, no.
The metabolism of the sugar arabinose is known to be influenced by an operon that is said to undergo both positive control and negative control.
Transcription of the ara operon is lead by the regulatory protein AraC, which then bound to the DNA.
When arabinose is present, it binds to AraC, and both parts of the AraC dimer are then also bound to the initiator, making transcription to move foreword.
When arabinose is absent, one part of the AraC dimer is often bounded to the initiator, while the other part is bounded to the operator, thereby hindering transcription.

why do heart cells have a higher percentage of mitochondria than liver and pituitary gland cells?
Answer:
This is because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.
The heart cells have a higher percentage of mitochondria than liver and pituitary gland cells because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.
What is the role of mitochondria in producing energy?The role of Mitochondria in producing energy are in charge of producing energy as ATP. The heart muscle has the highest energetical requirements. Several mitochondria compose these muscle cells because too much energy is needed to pump blood constantly.
Mitochondria are known as the one of the biggest organelles in the cell. They are semi-autonomous organelles surrounded by a double membrane that reproduce by binary fission and contain their own DNA, RNA, and ribosomes. Mitochondria are in charge of aerobic cell respiration, the process by which cells use organic compounds and turn them into energy.
Therefore, The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

why is mechanical digestion of food important?? please help I only need one reason marking brainliest btw
Answer:
it makes the food smaller
Explanation:
Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.

the age of fossils can sometimes be determined by radiometric dating, which is based on the constant rate of decay of radioactive isotopes. the time required for half of a radioactive isotope to decay is called the half-life of that isotope. for example, the isotope carbon-14 has a half-life of 5,730 years.
Answer:
17,190 years Radiometric dating is a technique for determining the age of fossils that is based on the fact that specific radioactive isotopes decay at a constant rate.
