Which systems in the body work together to maintain blood sugar levels? Select the best answer.A.digestive, circulatory B.circulatory, endocrine C.digestive, endocrine, nervous D.digestive, circulatory, endocrine, nervous

Answers

The correct answer is D. The digestive, circulatory, endocrine and nervous system all work together in maintain blood glucose levels. Digestive system is responsible for metabolic process for breaking down food in utilizable form. Circulatory systme helps is dispensing glucose into different parts of the blood. Endocrine is responsible for release of hormones for controlling blood glucose levels. Nervous system is responsible for release of chemical signals for hunger/satiation.

At the point when glucose becomes low, the level of insulin decreases and different cells in the pancreas discharge glucagon, which makes the liver transform put away glycogen once more into glucose and discharge it into the blood. This conveys glucose levels move down to typical. The digestive and endocrine work together to maintain blood sugar levels, the digestive will be the one to carry the glucose and endocrine will process it. The answer is C.

Some animals will run while others freeze, fight, camouflage or play dead. When the brain receives messages from the sympathetic and parasympathetic systems through neurons, the body responds by increasing blood pressure, heart rate and blood flow to the muscular system. These responses increase muscle tension to provide the body with extra speed and strength as well as thicken the blood to prevent blood loss should injuries incur during the threatening encounter.

Which best describes viruses? Viruses are nonliving infectious agents. Viruses can replicate without a host cell. Viruses can be killed by strong antibiotics. Viruses are similar to bacterial cells.

Answers

The option that best describes viruses is: Viruses are nonliving infectious agents. Viruses cannot replicate on their own and they need a host cell in order to survive. Antibiotics kill bacteria but not viruses. Antivirals and vaccines are made available to decrease the production of viruses, but not totally stopping them. Bacteria and virus differ in so many ways.

The option that best describes viruses is: Viruses are nonliving infectious agents. thus option A is correct.

What is viruses?

A virus is an infectious agent of small size and simple composition that can multiply only in living cells of animals, plants, or bacteria.

Viruses cannot replicate on their own and they need a host cell in order to survive. Antibiotics kill bacteria but not viruses. Antivirals and vaccines are made available to decrease the production of viruses, but not totally stopping them. Bacteria and virus differ in so many ways. so, option A is correct.

Environmental factors can have various effects on ecosystems. In August 2005, Hurricane Katrina caused significant damage in several states along the Gulf Coast, including Alabama, Mississippi, and Louisiana. Thousands of people were evacuated from their homes due to flooding and other damage caused by the storm. What environmental impact would Hurricane Katrina not have caused? early onset of spring change in marine ecosystems change in animal migration change in habitats

Answers

Hurricane Katrina would not have caused early onset of spring. The damaging winds/rains of the hurricane would have caused a change in marine ecosystems and habitats since the heavy winds/rain and storm surge eroded beaches, took down trees, and flooded out areas. As a result, animal migration also changed since some habitats that animals would normally migrate to were destroyed and no longer existed. The early onset of spring (aka. seasonal change) is not driven by individual weather systems.
