Answer:
All of the above traits combined
Explanation:
Phylogeny is an evolutionary history of development of a certain species or taxonomic group.
The purpose of phylogenies is to represent evolutionary relationships among a group of organisms.
During the reconstruction of phylogenies. Systematists often use a variety of traits in order to produce a good estimate of a phylogeny.
The use of molecular traits, gross morphological traits, behavioral and biochemical traits combined can give a good estimate of a phylogeny.
I have to say airborne infections. If the infection is airborne it can travel and infect many people more quickly and wide spread.
The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy., i.e., option A.
<h3>What is heterozygous?</h3>
The occurrence of different types of alleles is referred to as heterozygous condition.
A heterozygous genotype may consist of one normal allele and one mutated allele, or two distinct mutated alleles.
The missing options of the question are:
- Yy ´ yy
- YY ´ yy
- Yy ´ Yy
- yy ´ yy
The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy.
Thus, the correct option is A.

This question is incomplete because the images a section 2 are not given. I searched for the complete question but could not find it. However, based on my knowledge and the characteristics of the tundra this is the answer.
The correct answer is C. The climate is harsh, which limits the number of species that can live there.
Explanation
The tundra is the name of an ecosystem that occupies a fifth of the earth's surface, mainly in the northern hemisphere, this is characterized by having a frozen subsoil that limits the emergence and growth of natural vegetation and trees. This ecosystem is the coldest on the planet due to its location near the poles, its landscape is characterized by a layer of snow that covers most of the ground. In addition, the climatic conditions are extreme, which limits the number of plant and animal species that can live there. According to the above, the correct answer is C. The climate is harsh, which limits the number of species that can live there.
