Select the correct answer from each drop-down menu. Sodium and potassium ions are essential for muscle contractions of the heart
____ [38]

Answer:

1) By breaking of ATP to ADP

2) The sodium and potassium ions are transported using active transport process!

Explanation:

In cell, the movement of ions across the membrane at the expense of energy is known as Active Transport. The energy is used in the form of ATP(Adenosine Triphosphate) that gets converted to ADP(Adenosine diphosphate) during transport. It takes the ions from high concentration to low concentration. ADP contains one less phosphate group that ATP, as their name indicates and plays a prime role in the flow of energy to the cells.

Which of the following represents a type II survivorship curve?
Step2247 [10]

Answer:

The correct answer will be option-C.

Explanation:

The survivorship curves are the representation of the proportion of individuals of the given species which are alive at different ages in the population of species.  The curves are represented in the form of a graph with the number of individuals plotted on the y-axis to the age of survivorship on the x-axis.

The survivorship curves are of three types: Type I, II and III out of which type three represents the population with equal probability of dying at all age groups. This is represented by a straight line on the graph.

Thus, Option-c is the correct answer.

Alizarin yellow is a pH indicator that transitions from red to yellow when the pH falls from a value of 11 to below 10. Why is p
nydimaria [60]

Answer:

The correct answer is - acidic conditions wouldn't trigger a change in the color of Alizarin yellow.

Explanation:

The growth of E. coli generally occurs at neutral pH, however, its growth is normal at acidic conditions as well.  The change in the growth of  E. coli is not able to detect by alizarin.

The phenol red turns yellow in the presence of an acid, and the change in pH in an alkaline environment can be detected by the red color of phenol red. Growth of E.coli will grow in pH of 10-12 . But, very slowly. The color change in alizarin is also apparent at pH 10.2 to 12 only.
