Answer:
none of the other answer
Explanation:
because the chance of CF in child depends in having disease both father and mother if one of them have the disease then its maybe 1 in 1000 or more
Explanation:
<u>-how long it takes for the voltage-gatedNa+ channels to close at the end of an action potential</u>
Neurons have unique structures which aid in facilitating communication by sending and receiving electrical signals very efficient.
The refractory period describes a period between the initiation of an action potential where Na+ channels are closed, and immediately after the action potential’s peak. Action potentials would require an influx of more positively charged ions; these must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more Na+ than K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential.

The answer is : d. viscous fiber binds with bile in the intestine and is excreted in feces.
There are two types of fiber: insoluble and soluble(also called viscous).
Viscous fiber absorbe in water and forms a gel-like consistency in the intestines. This fiber can bind to the bile, which helps break down fat molecules into smaller pieces, and consequently bind up harmful toxins, cholesterol, and fat that it contains. Eventually, the fiber together with the bile, cholesterol, toxins and fats will leave the body.
Less cholestrol will reduce heart diseases.
There are two main types of research, which could be classified as manipulation and observation. Both types are fundamental in research.
<h3>Empirical research and evolution</h3>
Evolution is the subdiscipline in biology that studies how organisms change to adapt to challenging environmental conditions.
Empirical research refers to any scientific investigation in which conclusions are drawn from empirical evidence.
This type of research (empirical research) is based on observation of the natural world and experimental procedures.

The statement from the lab report that best represents a conclusion for this investigation is as follows: Olivia will continue to get high grades if she spends 2 hours studying every night (option B).
<h3>How is a conclusion written?</h3>
A conclusion is the outcome or result of a scientific process.
Every experiment is conducted to demonstrate a known truth or test the validity of a hypothesis.
This suggests that the conclusion should be structured in such a way that it must address the hypothesis of the experiment i.e. whether in support or not.
Therefore, the statement from the lab report that best represents a conclusion for this investigation is as follows: Olivia will continue to get high grades if she spends 2 hours studying every night.
