Answer:
<em>The correct option is D) homologous structures</em>
Explanation:
In evolutionary studies, a homologous structure can be described s a similar structure which is present in different species. This is because these spices might have a common ancestor in the past. For example, the forelimbs of humans and bat. They perform different functions but their structure is similar. They are also derived from the same embryonic origin. These similarities show that the bats and humans might have shared a common ancestor in the past.
Answer:
Monohybrid cross and Dihybrid cross are two genetic crossing methods that are used to study the inheritance of allele pairs.
Explanation:
These are useful in understanding the inheritance of traits from one generation to another. Monohybrid cross is a genetic cross that involves a single pair of genes that is responsible for one trait.

If the larva had one head at the posterior pole, it would be normal. The larva would have two heads, one at the front of its body and the other in the center.
What is bicoid mRNA?
When translated, bicoid protein forms a morphogen gradient that shapes the embryo's head and thorax if bicoid mRNA localizes to the anterior of the Drosophila egg.
How does the egg's bicoid RNA influence development?
According to recent research, Bicoid specifies the anterior of the Drosophila embryo in two different ways. It initially suppresses posterior development. It accomplishes this by attaching to and preventing caudal RNA, which is distributed throughout the egg and early embryo, from being translated.

Eubacteria are considered to be “true bacteria”. They are characterized to a lack of nuclear membrane, single circular chromosome and have cell walls composed of peptidogycan. A popular classification system divides all living beings into three domains: Eubacteria, Archaea, and Eukaryotes Hope this helps!
