A hypothesis is considered scientific if it has something that can be supported or refuted through carefully crafted experimentation or observation
Answer:
setting regulations for trains carrying cargo
Explanation:
USMA is the United States Military Academy in the West point. This academy provides a bachelor of science degree along with a cadet's performance in military and athletic activities.
USMA control diferrent functions in West Point and one of them is setting regulations for trains carrying cargo. USMA controls the department of defense and is responsible for making rules and regulation related to the trains carrying cargo.
Hence, the correct answer is "setting regulations for trains carrying cargo".
Answer:
In relation to voltage-gated ion channels, when depolarization occurs, Na⁺ gates open while K⁺ gates remain closed.
Explanation:
Depolarization is a phenomenon that occurs in cells like neurons, and depends on the distribution of ions in extracellular spaces and intraceluar.
-
Na⁺ is a predominantly extracellular cation.
- K⁺ has a high intracellular concentration.
This distribution occurs when the membrane potential is at rest, with a negative intracellular value.
Depolarization involves opening the Na⁺ channels, so that this cation enters the intracellular space, causing a change in cell voltage. Increasing Na⁺ concentration in intracellular space progressively produces an action potential, resulting in an electrical signal.
While depolarization occurs, K⁺ channels remain closed, limiting the output of this cation to extracellular space, which would prevent the action potential from occurring.

A) Law of Dominance explains why there is a 75% chance
<span>Dominant is always capitalized and recessive is always lower case so if you have Dd then its dominant since the first letter is dominant,if its yy then its recessive.you can also look at the punnet squares.</span>
