Answer:
B (active transport using ATP)
Explanation:
Movement of substances normally occur in the direction of concentration gradient/difference i.e. the difference in concentration of a substance across a membrane. Letting molecules diffuse or pass down their concentration gradient does not require energy but pumping those molecules against gradient requires energy in form of Adenosine triphosphate (ATP). This process is called Active transport.
In order to perform certain cellular processes, cells need to move substances from their surroundings into the cell across their cell membrane. Moving this substances against the concentration gradient between the cell membrane and its extracellular fluid requires energy (ATP).
An example is the sodium-pottasium pump employed by animal cells in which they expend energy to move K+ molecules into the cell and Na+ molecules outside the cell against the concentration gradient of their cell membrane and extracellular solution.
For both continental and ocean-floor topography, gentler slopes are represented by widely spaced lines while steeper slopes are represented by closely spaced lines.
Explanation:
The contour lines are one of the main, and one of the most used methods on the maps for representing the topography. Basically, the contour lines are closed lines that connect dots on the same elevation. It may sound very simple, but they do provide good insight into the topography, especially if the reader of the map knows how to interpret them well.
The contour lines are used both for continental and ocean-floor topography. The rules are the same for both, including the representation of the slopes. When a slope is gentler, the contour lines are more widely spaced. When a slope is steeper, the contour lines are much more closely spaced.
Some elements of the contour lines or that go with them to give better representation are:
- black dots (representing a top)
- thicker lines (every fifth, so that the counting is faster and easier)
- small lines with given direction (representing cliffs or highly steep slopes)
- numbers (providing information about elevation)

A telophase is the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
Answer:
It does not obey Mendel's law of dominance.
Explanation:
Epistasis is not complete dominance
Pharmacists may be more familiar and comfortable with the concept of quantitative rather than qualitative research. Quantitative research can be defined as “the means for testing objective theories by examining the relationship among variables which in turn can be measured so that numbered data can be analyzed using statistical procedures”.1 Pharmacists may have used such methods to carry out audits or surveys within their own practice settings; if so, they may have had a sense of “something missing” from their data
