The nasal cavity refers to the inside of the nose. It is a hollow space inside the nose and skull, which is surrounded with hairs and mucous membrane. The main function of the nasal cavity is to moisturize, warm, and filter the air getting inside the body before it gets inside the lungs.
The superior body of the nasal cavity is formed by four bones, that is, from anterior to posterior. These are:
1. Nasal
2. Frontal
3. Ethmoid (cribriform plate) and
4. Sphenoid (body)
The animals which appear most prominently in the diver scene from the tomb of the hunting and fishing include birds, fish and dolphins.
The Tomb of Hunting and Fishing comprises of two rooms. The frescos in the first room are frightfully disfigured but seem to portray Etruscans dancing outside.
Two trees frame the doorway into the second room. This room grants the tomb its name i.e. tomb of hunting and fishing since it illustrates a scene of men hunting and fishing.
Men in boats are fishing in a sea inhabited by fish and dolphins. On a rock surfacing in the water, a man appears as preparing to dive, whereas, one more man is seen climbing to the top.
In the meantime, another man is shown directing a slingshot at the birds that flock up above. This scene portrays the Etruscans' connection with nature and the significance of hunting and fishing in Etruscan society.

<h2>The Drought Continues </h2>
As the drought continues, all crops, minerals and nutrients will be lessened. If it continues then it will cause severe shortage of food for humans and animals which can cause even death. There is a strong contest for lack of food and water.
Food will become limited. Animals will coordinate how they get nutrients. Seed is the deciding constituent for the development of the birds’ beaks.
Larger G. Fortis will have clash with G. Magnirostris for the best available food that is the large seeds. Severe drought can cause death of many G. Magnirostris and G. Fortis that contain large beaks also comprise the big bird origins.
Consequently the result of this would be the beaking of G. Fortis that will ultimately become more small. In presentation it would be in size that they can avail food which is currently avaiable.
Answer:
Chromosome number variation: B. Down syndrome
Loss-of-function allele : D. PKU
Physiological trait
: E. Lactose metabolism
Discovery-based science
: A. Human Genome Project
Genetic cross: C. Model organism
Explanation:
Down syndrome is a condition in which there is an extra copy of the chromosome number 21. Hence, it is a chromosome number variation.
Physiological traits refers to any function of a body. Hence, it matches with lactose metabolism.
Human Genome Project was a project under which the whole genome of the humans were sequenced. Hence, it is a discovery based science.
A genetic cross is made between model organisms to test for the offsprings that would be produced from a cross. Hence, genetic cross and model organism math with each other.
