Answer:
C. Excessive potassium has diffused out causing hyperpolarization.
Explanation:
The nerve action potential can be divided into following stages:
- Stimulus is detected by the cell in resting stage.
- Sodium channels in the membrane open from where influx of sodium ions occur which is called depolarization
- After a while, sodium channels close and potassium channels open from where efflux of potassium ions occur which is called repolarization.
- The membrane potential further lowers due to continous efflux of potassium ions which is called hyperpolarization.
- After a while potassium channels close and membrane returns to its resting stage.
In the given figure, stage 4 depicts hyperpolarization because the membrane potential has dropped to the lowest point below -70mV. Hence, option C is correct.
Answer:
D. Tap water is one of the three test conditions of the independent variable, the type of water.
Explanation:
An independent variable is the part of a science experiment that is changed. Since you are changing the type of water, the independent variable would be the water. There are 3 types of water in this experiment, meaning the tap water is one of the 3 test conditions of the independent variable.

<h3>What is the Hox genes and evolution?</h3>
Hox proteins are a family of transcription factors that have undergone extensive conservation. They were first identified in Drosophila for their crucial functions in regulating segmental identity along the antero-posterior (AP) axis.
The regionalization of the AP axis and changes in the expression patterns of these genes have been strongly correlated during the past 30 years across a wide range of evolutionarily distinct species, indicating that Hox genes have been essential in the evolution of new body plans within Bilateria.
Despite this extensive functional conservation and the significance of these genes for AP patterning, many important concerns about Hox biology remain.

Answer:
Some of the compound subjects are given below:
- The Red and White earbuds
- My beginning and ending
- The Author and Financier
- His wife and legal consultant
- He is Judge and executioner
Some predicates are as given below
- Will rise again
- cannot return to the company the way it is
- coming to set the table
- travelling for the holidays
- walking like a sergeant
When mixed together in no particular arrangement intentional matching we have:
- The Red and White earbuds will rise again
- My beginning and end cannot return to the company the way it is
- The Author and Financier coming to set the table
- His wife and legal consultant traveling for the holidays
- He is the Judge and executioner walking like a sergeant
Explanation:
When two or more individual nouns or noun phrases are combined to form a single or longer noun phrase, it is called a compound subject. In other words, When more than one noun is put together to act as a single subject, it is said to behave as a compound subject. For example, "<em>My son and partner</em> will run this company when I travel out of the country". In the sentence above, the compound subject is "<em>My son and partner".</em>
Predicates on the other hand are parts of a sentence that contains the action words or phrases about a subject. For example, "The truck <em>has been sold" . </em>The part of the sentence that reads "<em>has been sold</em>" is the predicate. Whilst the subject is <em>the Truck.</em>
