Ontonic Pressure, or colloid osmotic pressure, is a form of osmotic pressure exerted by proteins, notably albumin, in a blood vessel's plasma (blood/liquid) that usually tends to pull water into the circulatory system. It is the opposing force to hydrostatic pressure.

Answer:
F-actin is a double helical filament as opposed to G-actin,which is a globular protein .Each actin filament has two ends,called the plus and
the minus ends, which makes it recognizable from each other.This gives the structure a distinct polarity.
Explanation:
Actin is the most abundant protein that is found in almost all eukaryotic cells.Its a most important part cytoskeleton as its a monomeric subunits(size 42kDa) of two types of filaments i.e. microfilaments and thin filaments in cells. Actin is essentially required to maintain stability and morphogenesis of cell.It is involved in numerous significant processes such as endocytosis,cell division and migration.Actin is present in two forms:
•G-actin
•F-actin
The two forms of actin are different structurally.
G- actin is a globular shaped protein,usually present in free form(a monomer),having a tight binding site for another actin monomer.Each monomer has ATP. Upon polymerization of G-actin monomers, a polymer called F-actin filaments is form. This process is driven by hydrolysis of ATP.
Answer:
B) They do not get enough oxygen, and die.
Explanation:
They loose oxygen due to the algae. The algae bloom uses up all the O2 in the plant structures
.
Answer:
Option C, resulting in variation genes being expressed in different ways due to environmental conditions
Explanation:
Several genetic traits are affected by both internal and external environmental conditions. Some common examples are – height , color of eye, hair color, skin color, and even some genetic diseases.
The internal environmental factors include – gender, temperature etc.
While the external environmental factors include drugs, chemicals, temperature, and light.
Hence, the external environmental condition i.e pH of soil is producing different color of flowers in a given plant
Hence, option C is correct
