It is known as a concentration gradient which in diffusion will always flow from ares of high concentration to areas of low concentrations
So i believe the answer to this is A.
If the question goes like this:
Which best describes plant classification?
<span><span>
A.
</span>Nonvascular plants are grouped into seedless and
seeded plants. </span>
<span><span>
B.
</span> Seedless
plants are grouped into gymnosperms and angiosperms.</span>
<span><span>
C.
</span>Gymnosperms are grouped into monocots and
dicots. </span>
<span><span>
D.
</span> Angiosperms are grouped into monocots and
dicots.</span>
<span>
The best answer
will be letter D. Angiosperms are grouped into monocots and dicots.</span>
Botanists grouped or classified together according to its
characteristics.

Answer:
The options
A. Additional cables
B. Slip rings
C. Multiple rows of detectors
D. Electron beam CT.
The CORRECT ANSWER IS B.
B. Slip rings
Explanation:
During the 1990s, the use of slip ring technology promoted consecutive rotation of the x-ray tube (via removal of cables) and concurrent couch locomotion.
The Sixth-generation CT scanning is referred to as helical (or spiral) CT—allowing procurement of volume multislice scanning.
Today's helical multislice scanners, makes use of thousands of detectors (around 60+ rows), can derive continuous data procurement of 128 "slices" per tube rotation and can undergo 3D multiplanar reformation (MPR).
Fifth-generation CT employs electron beam; as the ultra high-speed CT is employed majorly for cardiac imaging.
Answer:
a) epigenetic change.
Explanation:
Epigenetic is referred to changes BESIDES the changes in the genetic changes. It means, not related to mutations but to chemical changes such as methylation, acetylation, ubiquitylation, phosphorylation, that can interfere with the genetic expression. Chromatin modification is another way of epigenetic change.
