Answer:

Dominant

Explanation:

The dominant allele will always be shown in the phenotype if it's present, because the other allele would be dominant or recessive. If both alleles are dominant, then the dominant one shows, if one of the alleles is recessive, then the dominant allele would show over the recessive one.

I think of recessive alleles as "weak" where, they just follow behind whichever other allele exists there. If the other one is dominant, then the recessive one is behind it, and no one can see it. If it other allele is recessive, a recessive allele will be in front.

The respiratory structure that contracts and relaxes to allow air to flow in and out of the lungs is the: Group of answer choice

ohaa [14]

The respiratory structure that contracts and relaxes to allow air to flow in and out of the lungs is option(c) i.e, the diaphragm.

<h3>What is the diaphragm?</h3>

The diaphragm, a delicate skeletal muscle that separates the chest from the belly, is located at the base of the chest. When you breathe in, it flattens and shrinks. As a result, the lungs experience a vacuum effect that draws air in. The diaphragm relaxes and the air is forced out of the lungs when you exhale.

signs of diaphragm issues:

Acid reflux, heartburn, coughing, and difficulty swallowing.
alterations to skin tone (skin may turn blue).
rapid heartbeat, pressure in the chest, and/or breathing difficulties (especially when lying down).
Headaches.
Hiccups that persist or recur frequently.

Patients who need surgery for conditions affecting the chest, including diaphragm issues, are treated by a thoracic surgeon.

garri49 [273]

The evidence supporting the idea that modern birds and reptiles share a common ancestor is that feathers are a derived characteristic that first evolved in reptiles. Feathers represent an evolutionary derived trait.

In evolutionary biology, an autapomorphy is a distinctive phenotypic trait referred to as a derived trait, which is unique to a particular group/taxon.

The derived traits are phenotypic features that arise during the evolution of a particular taxonomic group.

These traits (derived traits) differ from the phenotypic trait of the ancestor of the group.
