The vinegar is a charged molecule, whereas, the oil is neutral. As like dissolves like, the vinegar can be dissolved with charged molecules and the oil can be dissolved with neutrals. So, to mix vinegar and oil shaking is required.
In case, the person does not mix oil and vinegar dressing before pouring this on the salad, it would not produce a good taste, as the content of vinegar and the oil would not be appropriate.
<u>Answer:</u>
Recent evidence suggest that feathers evolved from scales and suggest that 'feathers and pycnofibers' could be homologous.
<u>Explanation:</u>
- One of the major difficult issue related to bird evolution is the evolution of feathers.
- Feathers are considered as the most 'complex integumentary structures' which are found in vertebrates.
- Evolutionary developmental biology suggests that the 'planar scale structure' is been modified for developing into feathers by 'splitting' to form web like structures.
- Scales and Feathers consist of 'two distinct form of keratin' so it was thought that 'each type was exclusive skin structure' but recent study suggests that they are developmental expressions of same skin structures.
It is possible to predict that because of the decreased number of cone cells, cats have poor color vision.
<h3>What are cone cells?</h3>
Cone cells are specialized cells in the eye required to produce the spectra of color observed in nature.
Cone cells can be considered photoreceptors located in the retina of the eye (in animals and humans).
Cone cells act in the best way in bright light conditions, conversely to rod cells that serve to observe at the night.

Explanation:
A females inherits one X chromosome from each parent. A male can have hemophilia if he inherits an affected X chromosome (an X chromosome with a mutation in the gene that causes hemophilia) from his mother.
The mass percent of oxygen in Barium perchlorate is is 38%.
The molecular mass of Barium perchlorate (Ba(ClO4)2) is 336.2282 g/mol.
Percent composition of Oxygen will be = [(Molecular mass of Oxygen X 8)/ Molecular mass of Barium perchlorate] X 100%
= [(15.99 X 8)/336.2282] X 100% = 38%
