The right option is; c. biomes
Savanna is considered a transitional biome because it is intermediate between two biomes.
A savanna is a tropical grassland ecosystem that is characterized by widely spaced scattered trees. Savanna is an extensive plain that is regarded as a transitional biome because it is intermediate between moisture equator forests and tropical deserts. It covers about 20% of the earth’ surface. Savanna has seasonal water availability and during the dry season, there are strong evaporation which makes the trees such as baobab to shed their leaves while bushes and grasses wither.
I think the answer is sexual reproduction to carry out selective breeding.
From the diagram above, I dont think that organisms of the same order share a stronger evolutionary relationship than organisms in the same phylum. This is because, after kingdoms, the subsequent categories of increasing specificity are: phylum, class, order, family, genus, and species.
<h3>Levels in taxonomic classification</h3>
At each sublevel in the taxonomic classification system, organisms become more similar.
Organisms that share similar physical features and genetic sequences tend to be more closely related than those that do not.
Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among living organisms.
<h3>Phylogenetic tree</h3>
A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms
<h3>
Taxonomical classification</h3>
Taxonomy is the scientific study of naming, defining and classifying groups of living organisms based on shared characteristics. There are seven main taxonomic ranks:
- kingdom
- phylum ( in animals )or division ( in plants )
- class
- order
- family
- genus
- species.

<h2>Answer:</h2>
Chromosomes are structures present in the nucleus of the every organism's cell and it is the DNA packed with histones proteins.
Explanation:
DNA deoxyribo nucleic acid is the nucleotide sequence which is the blue print of the structural and functional characteristics of the whole organism.
Nucleus of the call is very small to be contain the DNA of cell. So DNA is present in the condense form by wrapping around the histones proteins which is known as cell division.
At the time of cell division, it is present in chromosomal form to equally divide the genetic material.
Answer:
The condition of the Earth had to become favourable before it could support any form of life.
The formation of the different layers around the earth like the ozone layer was necessary before life could originate. Primitive species such as some prokaryotes were able to live in hydrothermal conditions during the initial times. With the passage of time, as the concentration of oxygen increased due to photosynthetic prokaryotes, situations became favourable for eukaryotic organisms to arise.
