Answer:
The answer is Climate.
Phase 2, a plateau phase, is the longest phase. It is unique among excitable cells and marks the phase of calcium entry into the cell. Phase 3 is the phase of rapid repolarization that restores the membrane potential to its resting value.
B. circulatory system and nervous system
C. circulatory system and digestive sytem
D. nervous system and urinary system
Answer:
The answer is C
Answer: Autoimmune response
The immune system is the body's defense against germs like bacteria and viruses. When it senses these germs, it sends out an army of fighter cells to attack them. This called the immune response.
Autoimmunity is the immune response of an organism against its own healthy cells and tissues. This is always disadvantageous to a person because it mistakenly attacks our body. Autoimmune diseases which result from this now affect 24 million people. Examples of autoimmune diseases are rheumatoid arthritis, multiple sclerosis, thyroid disease, inflammatory bowel disease and lupus.
B) active transport using ATP and carrier proteins
C) passive transport by osmosis through the proteins
D) active transport using a process called phagocytosis
The correct option is passive transport by diffusion through proteins.
A type of cellular transport known as passive transport involves the movement of molecules and ions along concentration gradients. It indicates that a drug has a propensity to migrate from a region of higher concentration to a region of lower concentration.
Contrary to active transport, another type of cellular transport, which fundamentally requires ATP to move substances against their concentration gradient, the process does not require metabolic energy (e.g. ATP) because the chemicals are moved downhill or along their concentration gradient.
The four main methods of passive transport are osmosis, filtration, simple diffusion, and assisted diffusion.
Therefore, The correct option is passive transport by diffusion through proteins.

Answer: True
Explanation:
Unnatural occurences are those catastrophic events induced by humans which can exert drastic impact over the ecosystem. These may include deforestation, forest fire, intentional explosion, and others. This will result in loss of many species due to damage caused to the non-living physical environment.
