Answer:
Option B, paranasal sinuses: house olfactory receptors
Explanation:
Paranasal sinuses are located between the facial and skull bone. These are cavities in the maxilla, frontal, sphenoid, and ethmoid bones which ultimately drain into the nasal cavity.
Their functions include the following –
a) Heating the inhaled air
b) Humidifying the inhaled air
c) Make skull lighter
d) Produce sound by resonating the voice
e) Lubricate the nasal cavity
Hence, option B is correct
The believe that the best answer among the choices provided by the question is the E. All contain histones.

Relief and Climate is what controls the landscape development. We will focus on climate because this is where the life activity included. Some activity weakens substrate is for burrowing and wedging while some strengthens substrate is for binding. This is because of the time, evolution cannot occur without time and continue response to agents with during long periods.
The answer is A if you have any more questions let me know
This law is called Mendel's second law, or the Law of Independent Assortment.
The law is derived from observations of dihybrid crosses. A classic example involves seed shape and color in garden peas. The shape may be round (caused by a dominant allele, denoted by R) or wrinkled (recessive, r). The wrinkling is caused by a mutation preventing the formation of branches in starch molecules. The color of the seeds may be yellow (dominant, Y) or green (recessive, y). The green color results from a variant sequence in a gene; the seeds fail to develop normally.
Parentals are RRYY and rryy.
The F1 plants are RrYy.
The F2 plants show independent segregation of the alleles for the two characteristics, shape and color. A Punnett grid predicts a 9:3:3:1 ratio for the phenotypes round yellow, round green, wrinkled yellow, and wrinkled green.
