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.

KIM [24]

Answer:

Option E, C tactile (CT) afferent

Explanation:

Whenever a slow moving gentle touch experienced, the response is due to the nerve fibers called C-Tactile afferents (CTs).  

C-Tactile afferents (CTs) are unmyelinated mechanoreceptors  of low threshold and low conduction velocities.  

In humans, CT neurons are found in hairy skin.  

The pleasant feeling observed during a slow gentle touch is due to the interaction of  

CT neurons project to the insular cortex in the brain

Hence, option E is correct

Mandarinka [93]

Answer:

Options I and II

Explanation:

Evolution refers to the changes that occurs in the morphology, appearance and behavior of an organism over a due course of time. This changes occurs due to the natural selection method, where organisms undergoes changes and adapts to the newly habitable environment.

The above given options I and II are the evidences of evolution. The similarities in terms of bones and their defined structure between the bat wings and porpoise fins are signs of evolution that has taken place over a definite span of time. Also, the changes in the various breeds of dog that are caused by the artificial selection method is also an example of evolution.

Thus, the correct answers are options I and II.
