ANSWER:

Phosphatidylinositol-4,5-bisphosphate (PIP2), which constitutes ∼1% of the plasma membrane phospholipid, PLAYS a key role in membrane-delimited SIGNALING.

ANSWER:

We KNOWN that normality is the gram equivalent WEIGHT of solute per unit volume .

Also gram equivalent weight (x) is calculated as follow .

X= molecular weight of NAOH / acidity of NAOH .

1000ml -----1N ----- 40 G .

100 ml ---- 0.1 ---X .

From above we can see that to prepare 1000ml , 1N NAOH solution require 40g of NAOH .

So to prepare 100 ml of 0.1 N NAOH solution require Xg of NAOH calculated as follow.

From l

1000ml × 1N × Xg = 40 g × 100ml × 0.1N .

X = 40g × 100ml × 0.1 × 1000ml × 1N .

X = 0.4 g NAOH.

Answer:

Answer:

The atoms of only a few elements called noble gases (Such as helium, neon, ARGON and kryton, etc.) are CHEMICALLY UNREACTIVE and exist in the free state or INDEPENDENTLY. Atoms of most of the elements are chemically very reactive and do not exist in the free state or independently

I can give you in short also like.

Most atoms of elements do not have octet and they try to attain noble gas configuration , that's why they react and form bonds and cannot exist independently whereas molecules are group of atoms that have form bonds.

Transpiration is a process similar to EVAPORATION where liquid WATER is turned into water vapor by the plants. The ROOTS of the plants absorb the water and push it toward LEAVES where it is used for photosynthesis. The extra water is moved out of leaves through stomata (very tiny openings on leaves) as water vapor.

ANSWER:

ETHYL ALCOHOL METHYLCARBINOL

Answer:

As an example of the formation of complex ions, CONSIDER the addition of ammonia to an aqueous SOLUTION of the hydrated Cu2+ ion {[Cu(H2O)6]2+}. Because it is a stronger base than H2O, ammonia replaces the water molecules in the hydrated ion to FORM the [Cu(NH3)4(H2O)2]2+ ion.

Electronic configuration, also called electronic structure, the ARRANGEMENT of electrons in energy levels around an atomic nucleus. ... In terms of a more refined, quantum-mechanical model, the K–Q shells are subdivided into a set of ORBITALS (see orbital), each of which can be OCCUPIED by no more than a pair of electrons.
