A :-) Osmosis. Osmosis is the movement of water across a membrane from an area of low solute concentration to an area of high solute concentration.
Answer:
A. 50%
Explanation:
Using Gregor Mendel's genetics cross, the probability of obtaining brown hair is 50% or 2/4. In Gregor Mendel's genetics cross, the dominant gene represented as Bb is crossed against the recessive, bb. On completing the cross, the products of the cross are two dorminant gene (brown hair) with a trait of red hair and the recessive gene will not be expressed, while the two remaining products are recessive, bb and therefore the recessive gene for red hair will be expressed.
Answer:
Explanation:
Hydrogen cyanide (HCN)
The molecular geometry of HCN is linear. The compound is polar in nature.
As Carbon is bonded to two atoms, it follows the molecular geometry of AX2. And as per VSEPR theory, molecules covered under AX2 have a linear molecular geometry.
Hence Hydrogen Cyanide has linear molecular geometry.
Sandpaper, a rough texture, granular texture
The question is incomplete as it does not have the options which are:
A. carbohydrate molecules
B. hydrophilic molecules
C. amphipathic molecules
D. hydrophobic molecules
Answer:
C. amphipathic molecules
Explanation:
Amphipathic molecules are the molecule which posses molecular arrangement in a way that they possess both the water-loving species and water-repelling species.
The amphipathic molecule is best for the formation of cell membranes like the lipid molecules which is comprised of both hydrophobic tail and a hydrophilic head.
Since the evidence shows that the first cell was formed in the aqueous bodies especially in the oceans by the aggregation of a molecule, therefore, the molecules for membrane must be arranged in a way that it could interact with the surrounding environment as well as protect from the environment and the result was the amphipathic molecules.
Thus, amphipathic molecules is correct.
