Answer:
1. when there is a cut, the surface area of the skin becomes rough which activates the Thrombin, that catalyzes the activation of fibrinogen present in plasma.
2. albumin contributes mostly of making plasma protein
3. albumin contributes the major portion to the osmotic pressure of plasma.
4. fibrinogen mainly forms the structural framework of a blood clot during blood coagulation.
The answer is C) Ecological niches become available for organisms to evolve into by adaptive radiation
If someone had an inadequate intake of sodium over several days, it would be most difficult for the body to maintain homeostasis.
<h3>Why is sodium important for homeostasis? </h3>
Most of the sodium in our body is present in the extracellular fluid (ECF). The concentration of sodium in the body is measured relative to the amount of water in the body.
Maintaining proper sodium concentration is therefore essential for maintaining water balance in the body. It also helps in the proper functioning of neurons by assisting in the conduction of impulses.
Sodium concentration is also important for muscle contraction. Proper sodium concentration maintains osmolality of the extracellular fluid which maintains the volume of blood and plasma in the body.
Therefore, an inadequate intake of sodium, over several days will affect the homeostasis of the body.

Answer and Explanation:
The <u>Scientific theory</u> describes an ongoing, ever-changing process of investigation, inquiry, and validation. Data gathered is typically analysed through available theories and laws; these may be utilized in testing and confirming hypotheses.
However, when new information becomes available, these may alter the understanding of a certain theory or premise. In astronomy, imaging, is integral to understanding and validating theoretical models of our universe. The observation of phenomena by improved imaging over the years has gradually changed human perception of the universe.
For instance, the Ptolemaic model of the universe placed Earth at its center, while improved imaging with telescopes completely disproved this theory. Keeping an open mind is integral to the scientific process; additional information alters our perception of observations carried out through investigations. Being open minded, and receptive to these changes drives scientific discovery and processes.
