Answer:
The correct answer is - option A. They evolved separately as they moved north and became two separate species
Explanation:
Greenish warbler is a leaf warbler present in many regions in the world and shows migration in winters in the Indian region. The main region of the migration is Tibetan Plateau.
They migrated from the southern part of these birds range and moved north and evolved separately from the main species and become two distinct species due to their geolocation and environment change.
Answer: the adult human body has 206 bones in total
to understand what the result of these crosses would be like, we need to know what is gene
<h3>Gene</h3><h3 />
The gene is a strand of a DNA molecule (deoxyribonucleic acid), which carries the characteristics that are genetically inherited. They are composed of a sequence of DNA and RNA (ribonucleic acid), responsible for the production and synthesis of proteins in the cell. The gene's greatest attribution, therefore, is to be a store and transmitter of information.
Genes can be classified into:
- Dominant genes: assume the specific characteristic in the offspring;
- Recessive genes: manifests itself in the absence of the dominant gene;
- Structural genes: are those that contain the information that will determine the structure of living beings;
- Operator gene: acts on the functioning of other genes;
- Regulatory gene: responsible for controlling the synthesis and transcription of other genes.

in genetics, are individuals who have pairs of genes that are identical or different alleles. This means that while the has two identical genes alleles, with the beings the opposite happens, since they have two different genes alleles.
with this information we can say that a white and short plant, when crossed with a plant for both traits, has 60% of this plant being with expression of the dominant genes and 40% of being with expression of the recessive gene.

Certain elements are required in large quantities, and others are required in small amounts by the body, but both are essential for the survival of the cells. The cells which are required in large amounts are called as macronutrients, while the ones required in small quantities are called as micronutrients, or trace elements.
Hence, the answer is trace elements or micronutrients.
