Answer: The body maintains homeostasis by positive and negative feedback mechanism.
Explanation:
The body maintains the internal temperature and metabolism with respect to change in environment.
In case the temperature outside is very cold and the body starts shivering by the movement of skeletal muscles, this is done to maintain the temperature inside body. This is positive feedback.
When the temperature inside the body is maintained, then body stops shivering. This is negative feedback.
This is how the body maintains homeostasis.

Answer:
Yes, D is correct.
Explanation:
Answer:
The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.
Answer and explanation:
If excessive amounts of acetoacetic acid were to build up in the body, the pH of the blood would decrease, because the blood would become more acidic.
Acetoacetic acid is produced because of lipolysis (fat degradation) or because of the breakdown of amino acids. This is a normal biochemical process, but it can lead to serious issues when the levels of acetoacetic acid rise more than they should.
Patients with Diabetes Mellitus have a deficiency in their insulin production. Insulin is the only hormone that can make glucose enter the cells, which is important because glucose (sugar) is processed inside the cells to produce ATP (a molecule high in energy).
Patients with Diabetes can't get the glucose inside their cells, so the blood sugar levels rise in the blood (hyperglycemia). Since the body still needs ATP to function properly, energy requirements are being met via the degradation of fat and amino acids - which generates acetoacetic acid. If this continues, the pH drops and Diabetic Ketoacidosis occurs. This condition is life-threatening.
Answer:
Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment; and (3) they separate vital but incompatible metabolic processes conducted within organelles.
- ER
- Chloroplast
- Mitochondria
- Golgi Apparatus
Answer:
The chloroplast
Explanation:
The choloroplast takes in nutriets (sunlight) and converts it into energy for the plant
Answer:
Answer is D. Pseudopodia.
Explanation:
Pseudopodia are described as a temporary extension of the cytoplasm. These are found in some certain unicellular protists like amoeba.
The pseudopodia is useful for movement and ingestion. They are useful in capturing or engulfing prey for a process known as phagocytosis.
