Homeostasis is the body's ability to maintain constant _ conditions when _ conditions change.a. internal; external
b. external; internal
c. oxygen; temperature
d. temperature; pH

Answers

Answer 1

Answer:

The best answer is a - internal : external
Homeostasis is the body's ability to maintain constant internal conditions when external conditions change.

It is the ability of an organism or a cell to regulate its internal conditions, usually through a system of feedback controls so as to stabilize the health and functioning regardless of the outside changing of conditions..

For example in man, homeostasis occurs when the body regulates body temperature in an effort to maintain an internal temperature at around 37° C.

Answer 2

Answer:

Homeostasis is the body's ability to maintain constant internal conditions when external conditions change.

Homeostasis is the body's ability to maintain constant internal conditions when external conditions change.

It is the process by which the body adjusts to changes and maintains equilibrium by ensuring that body functions remain within a certain range.

For example, when the body becomes too warm, adjustments are made to cool the body.

Homeostasis is essential for the proper functioning of the body and is regulated through various feedback mechanisms.

Which fat is most likely a solid at room temperature?

Answers

The type of fat which is most likely a solid at room temperature would be saturated fat. If you think of olive oil and canola oil, both of them are liiquid at room temperature. If you're thinking of lard, it's hard at room temperature.

Final answer:

Saturated fats, which lack double carbon bonds in their fatty acid chains, are most likely to be solid at room temperature. These fats are found in animal products like meat and butter.

Explanation:

The type of fat that is most likely to be solid at room temperature is saturated fat. Saturated fats, such as those found in meat and butter, consist of fatty acid chains that lack double carbon bonds and are therefore able to pack tightly together due to their straight and rigid structure. As a result, they remain solid at room temperature. Examples include animal fats containing stearic acid and palmitic acid. In contrast, unsaturated fats, which contain at least one double bond in their fatty acid chains, cannot pack tightly together and are usually liquid at room temperature.

The nitrogen cycle _________. A. indicates the process of uptake of nitrates (NO₃ minus) by plants.
B. marks transformation of ammonium (NH₄ plus) into nitrites (NO₂ minus) by bacteria.
C. marks synthesis of ammonium (NH₄ plus) by decomposers.
D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.
E. marks organisms that take part in transformation of nitrogen from the atmosphere (N₂) into ammonium (NH₄ plus) and are located in the root nodules.

Answers

Answer:

D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.

Explanation:

The nitrogen cycle is a biogeochemical cycle which involves transformation of atmoshperic nitrogen into many chemical forms including nitrite (NO2), nitrates (NO3) and ammonium (NH4).

The process of nitrogen cycle starts with the process of nitrogen fixation. In this process several nitrogen fixation bacteria such as cyno bacteria converts the atmospheric nitrogen into ammonium (NH4) in the soil. The resultant ammonium (NH4) can be directly used by plants or transform into nitrites or nitrates through nitrification process.

Hence, the correct option is D.

Which of the following is a contributing reason behind emerging disease? a. The lack of evolution in hostsB. The overuse of antibioticsC. The absence of migration or travel in organismsD. The lack of evolution in pathogens

Answers

The correct answer should be B. The overuse of antibiotics. Since antibiotics as their name says kill biotics, that is, they fight against bacteria, they were used a lot and bacteria started developing resistance to them which is a common thing. Since it's difficult to find new types and the trials last long, new diseases are emerging faster than we can create medicine for them.

_______________ is an abnormal episode of motor, sensory, autonomic, or psychic activity resulting from a sudden, abnormal, uncontrolled electrical discharge from cerebral neurons.

Answers

Answer:

Seizure is an abnormal episode of motor, sensory, autonomic, or psychic activity resulting from a sudden, abnormal, uncontrolled electrical discharge from cerebral neurons.

Explanation:

Seizure is also formally known as an epileptic seizure which it's symptoms involve uncontrolled body movements mostly with every part of the body and loss of consciousness. Epileptic seizure lasts for the maximum of two minutes before the person returns to a normal state. Bladder control however, is usually absent at this stage. Epileptic seizure can be caused by either provocation or without provocation

In provocation, the causes are very low blood sugar and blood sodium, severe fever, brain infection or concussion. Without provocation; brain injury or tumor and a stroke.

When a seizure lasts more than a maximum of two minutes, it is declared an emergency but some seizures do last for about five minutes and it is regarded as normal. There hasn't been any form of cure for epileptic seizures but there are temporary treatments which can prevent frequent seizures.

Answer:

Siezures

Explanation:

A seizure can simply be seen as a sudden, uncontrolled electrical disturbance in the brain. Seizures can cause involuntary muscular movements and behavioral changes. They can also affect levels of consciousness. Most seizures however, do not last very long. They usually last from 30 seconds to two minutes
