Answer:
The reason hydrogen bonding occurs is because the electron is not shared evenly between a hydrogen atom and a negatively charged atom.
Explanation:
Hydrogen in a bond still only has one electron, while it takes two electrons for a stable electron pair. Any compound with polar covalent bonds has the potential to form hydrogen bonds.
Options are:
a) lymph.
b) interstitial fluid.
c) extracellular fluid (ECF).
<span>d) plasma.

All the following are correct terms for this fluid except lymph.
The interstitial fluid surrounds the cells in the body. The other major component of the ECF is the intravascular fluid of the circulatory system called blood plasma<span>.
</span>Lymph is<span> a fluid which contains infection-fighting white blood cells, throughout the body.</span>
Answer:
There are many different genetic disorders associated with genomic instability, including the Cockayne's syndrome and the Fanconi's anemia.
Explanation:
It has been shown that Cockayne's syndrome is associated with genome instability caused by oxidative DNA damage. Moreover, the Fanconi's anemia has been associated with the dysregulation of transcriptional R-loops formed by RNA:DNA hybrids in the human genome.
Answer: Kingdom Animalia (Multicellular Heterotrophs)
Explanation:
Heterotrophs (animals) cannot make their own food like the green plant (autotrophic mode of nutrition). So they have to search for foods by moving about. They can feed in plants, other organisms /animals or feed on dead materials.
Animals are multicellular (with many specialised cells). For example the cell in our nose are meant to respond to smell while that of the eyes are specialised for light capture. Our muscle cells focused on movement. Unlike the plants, animals lack cell walls.
Answer:
Echinoderms use its tube feet for "<u>movement, respiration and taking food".</u>
Explanation:
Tube Feet are tiny tube like projections on oral side of echinoderms. They use it for movement, food and respiration. Echinoderms also use them to stick the ocean floor and move at a leisurely pace.
