Answer:
The correct option is E) Contraction still occurs because Ca2+ can enter the cell directly through Ca2+ channels in the plasma membrane and bind to calmodulin.
Usually, the calcium ions are released from the sarcoplasmic reticulum of a cell during a muscle contraction, but if those are blocked, the contractions is an cell can still arise through the calcium ions which are present in the cell membrane of a cell.
1. The correct answer is alcoholic fermentation.
Alcoholic fermentation, also known as ethanol fermentation, refers to a biological procedure that transforms sugars, like fructose, glucose, and sucrose into cellular energy, generating carbon dioxide and ethanol and the by-products.
2. A scientific theory refers to a well-substantiated illustration of certain features of the natural world, on the basis of the body of facts, which have been spontaneously confirmed via experiment and observation. Thus, the statement, that it has the same meaning in science as it does in daily life is incorrect.
3. The correct answer is mutualism.
Mutualism refers to a symbiotic association in which both the species benefit.
4. The correct answer is ATP.
ATP refers to the biochemical manner to use and store energy. It is in fact, utilized by every cell of the body as the source of energy, which maintains everything.
It is true that z<span>oning laws may designate parcels of land for specific uses, but sometimes the economic benefit of developing wetlands, grasslands or forested areas overrules the protection of such land.
This is especially true if a rare plant or something thought to be extinct starts growing there - then the nature cannot be disrupted so as to make a building or something else there. </span>
The correct answer is "the formation of new brain cell connections as the result of reading a book".
Usually, neuroplasticity is apparent in young children when the central nervous system has an abundance of neurons. This is always in the context of forming new brain cell connections or synapses that will lead the person to access the information quicker. This also exemplifies the principle of use and disuse when it comes to knowledge.
The other choices concerns the skeletal system, cardiovascular system, and the endocrine/reproductive system; all of which do not have a relation with neuroplasticity.
