Human eyes have a very different morphology from that of fly eyes. If Pax6 sequence and function is highly conserved, how can on
MatroZZZ [7]

Answer:

Nutritive and varied stimulus exposure divergence

Explanation:

No doubt that Human and Eyes of fly have Pax6 conserved sequences and their primary function is highly conserved.but there is a very simple explanation for their morphological divergence. First divergence takes place where flies have totally different stimulus exposure and that continuous exposure develops a more suitable hexagonal facets by evolutionary point of view are necessary for quick motion detection. Although they can only differ between bright and dark, they don't provide a very pure vision but this is necessary for them. The ectopic expression can be explained by their different nutritive exposure over the course of their evolution.

) A field biologist finds an unfamiliar single-celled organism in a sample from the surface of a marshy area. What observations
liberstina [14]

Answer:

Genetic analysis, structure analysis and study the behaviour.

Explanation:

Genetic analysis, structure analysis and study the behaviour of organisms are the observations or tests that would make it possible to determine whether it is a protozoan, fungus, or algae because these analysis provides information about the genetic makeup and structure of their cell. If the cell wall is made of chitin then it is considered as fungi, if the cell wall is made of peptidoglycan then it is an algae and if the cell wall is not present then it is considered as animals like protist.

.Why must farmers fertilize their fields, yet a temperate deciduous forest regenerates and recharges without any problem?
ch4aika [34]
The trees in the wild, compared to the ones we grow, are meant for not being taken care of. Back in the dinosaur ages, the tress there did not need to be taken care of. These genes are passed down through each generation of plants. When a crop is planted by a human so many times, like corn, they become dependent and rely on a source instead of being able to deal with their surroundings
