Answer:
knirps (a gap gene)
wingless (a segment-polarity gene)
kruppel (a gap gene)
even-skipped ( a pair-rule gene)
hunchback (a gap gene)
hedgehog (a segment-polarity gene)
Explanation:
The gap, segment-polarity and pair-rule genes play central roles in controlling embryonic development of arthropods. In the first place, the gap genes are associated with the formation of contiguous body segments, thereby mutations in these genes result in gaps in the normal body plan of the embryo. For example, in <em>Drosophila melanogaster</em>, mutations in the <em>knirps, Krüppel </em>and<em> hunchback</em> genes result in deletion of body segments. These genes are also known to regulate segment polarity genes, which determine the polarity of the embryonic parasegments by modulating Wnt and Hedgehog signaling pathways. Finally, the pair-rule genes work together with gap genes to control embryonic development of alternating body segments.
Answer:
MaxSan. The two fields of study that provide the core information that is used to classify organisms are: Morphology, a branch of biology that studies the form or structure of living beings. Biochemistry, is responsible for studying from a chemical perspective the composition, structure and functions of living beings
HOPE THIS HELPED!! XD
Answer:
A
Explanation:
Photosynthesis is the turning of light into energy (please correct me if I'm wrong)
the splitting of an atom is called "nuclear fission".
The answer is mucus.
A nonspecific defense is a type of defense in which the protection is always the same. It doesn't matter what the invader is. Physical barriers like the skin, the mucus secreated, protects us against invasion of microorganisms. The other options are specific defenses for a certain type of invador and will only work against them.
